FIG. 3 is a scene of at least one camera unit in a plurality of camera units sensing and tracking a dart according to an embodiment of the present invention.

The screen shown in FIG. 3 and the screen for tracking darts are only examples of the embodiments of the present invention. Those with ordinary knowledge in the field should be familiar with screens with different shapes or different changes are also included in the scope of the patent application of the present invention. In addition, although other variables, information and their combinations are not shown in FIG. 3, they are still included in the scope of patent application of the present invention.

In addition, the screen depicted in Figure 3 can be viewed through the display module of the dart game device 100 142 output, or output from the output unit (not shown) of the user terminal (meaning referee terminal), or output from various devices and terminals not mentioned above.

According to an embodiment of the present invention, each of the plural camera units may include a camera movement subunit to control the shooting direction of the camera unit. The camera movement sub-unit allows the camera module 150 to move up, down, left, and right with respect to the target (that is, the dart 111 or the player) and take pictures. In addition, the camera moving sub-unit can operate the camera module 150 to capture a position set by the user under the command of the controller 190.

In addition, each of the plurality of camera units includes a camera focal length adjustment subunit for controlling the focal length of the camera unit. The camera focal length adjustment subunit is used to adjust the focal length again, so as to maintain the focus when the situation changes, and prevent the target (that is, the dart 111 or the player) from moving away from or approaching the camera module 150, and the focal length is out of focus when the camera moves. In addition, the controller 190 can make the camera focal length adjustment sub-unit alternately and repeatedly perform optical zoom through commands, and use a predetermined magnification ratio to enlarge or reduce the image at the position set by the user. Among them, the camera focal length adjustment sub-unit can adjust the focal length through sonar detection or infrared beam. In detail, the camera focal length adjustment sub-unit is operated by emitting light or sound pulse waves (meaning ultrasonic waves). The camera focus adjustment subunit can measure the return time of the echo from the target (that is, the dart 111 or the player). The controller 190 can calculate the distance from the reference point to the target at the speed of sound by measuring the delay time of the ultrasonic echo. In this case, the controller 190 can adjust the focal length of the camera module 150 according to the calculated target distance. In addition, the focus adjustment sub-unit can measure the target distance by using an infrared beam. In detail, the camera focus adjustment sub-unit can measure the target distance through the method of the intensity and time of the infrared beam reflected by the object.

In addition, at least one camera unit of the plurality of camera units may include sensing player movement The operation sensing subunit. The operation sensing subunit may be an occupancy proximity sensor. The occupancy proximity sensor is used to detect the presence of a person or object at a predetermined location, and generate a signal when the object moves or stops. In addition, the occupancy proximity sensor can verify the existence of the target through the reference point, or its position, movement, partition, etc. to verify the proper position of the target. In detail, the occupancy proximity sensor is classified into a contact type or a non-contact type, which can include a photoelectric sensor, an inductive proximity sensor, a capacitive proximity sensor, and an ultrasonic proximity sensor.

As described above, when the operation sensing subunit of at least one camera unit in the plurality of camera units senses the dart 111, the controller 190 can be configured to further control the camera action subunit and the camera focus adjustment subunit, thereby tracking and shooting. The sensed dart 111.

In addition, the operation sensing subunit may be a human body sensor in the form of an infrared sensor. The human body sensor will be described in detail below. All objects have a temperature higher than absolute zero (-273), and emit radiation corresponding to the temperature or even between objects; the emitted far-infrared rays can be lower than the temperature of the human body. A higher temperature object can radiate more infrared rays than a lower temperature object, and its radiant energy peak is close to the short wavelength end, which means that when the temperature is higher, the radiated energy is close to the visible light region. The surface temperature of human beings will vary with wearing or surrounding temperature, from about 20°C to 35°C; the peak of the infrared wavelength distribution of radiation is about 10μm. The human body sensor can sense the presence of the player by sensing the change of infrared rays.

In addition, the human body sensor can be used for at least some of the camera units in the plurality of camera modules 150. In this case, the lens used in the camera unit of the camera module 150 may include a lens used in a human body sensor to sense the movement of a person, or include a light collector such as a mirror. The human body sensor itself has a very wide and undetectable area, because the human body sensor can only sense an approaching human body. At least some of the lenses in the camera unit can be achieved through the use of multiple mirrors or multiple Fresnel (Multi-Fresnel) lens (meaning flat lens with concentric grooves), combined with multiple mirrors, lenses and dome-shaped lenses, radially arrange a large number of sensing areas, and effectively sense the human body at a wide angle .

When the human body sensor detects the player's movement, the controller 190 can be used to control the camera movement subunit and the camera focus adjustment subunit as described above, so at least one camera unit of the plurality of camera units will track and photograph the player. When the camera module 150 senses the player or the dart 111, the display module 142 displays the sensing area 113 generated by the controller 190. Among them, the sensing area 113 can display the focus frame of the target (that is, the dart 111 or a player's face) sensed by the camera module 150. In addition, when the camera module 150 senses the movement of the target, the display module 142 will track the target and display the sensing area 113. In addition, the display module 142 can display the sensing area 113 through various colors, shapes, and thicknesses.

On the other hand, the controller 190 uses the photos taken by the second camera unit 152 to identify the player. In detail, the second camera unit 152 is used to zoom in and photograph the player's face or upper body. In addition, the controller 190 can analyze the currently captured image of the user's face or upper body. In addition, the controller 190 can verify the player's identity by comparing the player's face or upper body image captured by the second camera unit 152 in advance.

In detail, the approved player identification technology is a facial recognition technology. Among them, the face recognition technology represents the biometric recognition technology, which recognizes the player's face through the pictures taken by the camera module 150, and identifies the player through the process of extracting the face area. In addition, the controller 190 uses information evaluation such as brightness, motion, color, and eye position to recognize the player's face and background in the pictures taken by the camera module 150. For example, the controller 190 uses the camera module 150 to photograph the player's face brightness difference, the background, and the main parts of the face such as eyes, nose, and mouth, so as to recognize the player's face. Play The home face information is stored in the memory 180 through the controller 190. The controller 190 finally compares the stored face information of the player with the photographed face picture of the player, and verifies the identity of the player by the pixel value of the picture.

In the embodiment of the present invention, the controller 190 analyzes the first picture taken by the first camera unit 151 to sense the throwing line 115 in the first picture. In addition, the controller 190 can add the throwing line 115 to the first picture as a highlight, so that the display module 142 can display and mark the throwing line 115 in the first picture. In addition, in order for the player to easily recognize the throwing line 115, the controller 190 may mark the throwing line 115 with various colors on the display module 142. In addition, when the controller 190 senses that the player exceeds the throwing line 115 when throwing a dart, the controller 190 will make a warning sound through the sound output module 141, and mark the throwing line 115 through the display module 142 to make the player aware of this For cheating.

In an embodiment of the present invention, the controller 190 can synthesize the action photos taken by the first camera module 151 to the fourth camera module 154 to generate a set of continuous picture data. The continuous picture data is a panoramic action picture. In addition, the controller 190 can extract multiple sets of still and action photos taken by the first camera module 151 to the fourth camera module 154, and create a panoramic picture from the extracted plural still photos or action photos. Among them, the controller 190 generates the trajectory of the dart 111 in the panoramic action photo. The controller 190 uses various display methods, such as lines and colors, to mark the trajectory of the dart 111.

According to an aspect of the present invention, the camera module 150 can photograph the process of the dart 111 thrown by the player reaching the target 110 to produce action photo data. The camera module 150 transmits the photographed image data to the controller 190, and the controller 190 stores the image data in the memory 180. In addition, the controller 190 can send the image data to the dart game server (that is, the server that determines cheating) through the communication module 160. In addition, the controller 190 transmits the photo data to the database server (not Draw). The dart game server (not shown) and/or the database server (not shown) can be two actually separated servers or the dart game server (not shown) and/or the database server ( (Not shown) can be integrated into one server, and then the functions implemented by both will be used to distinguish which server it is. In addition, as mentioned above, the same server can serve as a dart game server (not shown) and/or a database server (not shown) at the same time.

FIG. 4 is an action photo of the split screen output by a display module of the embodiment of the dart game device of the present invention.

The screen and the moving picture split screen depicted in FIG. 4 are only examples of embodiments of the present invention. Those with ordinary knowledge in the field can know that the scope of the patent application of the present invention includes screens of different shapes or other variable values. In addition, although other variables, information and their combinations are not shown in FIG. 4, they are still included in the scope of the patent application of the present invention.

In an embodiment of the present invention, the display module 142 can divide at least some of the action photos taken by the plurality of camera units, and output the action photos on a screen. For example, the display module 142 can divide and output the first action photo 401, the second action photo 403, the third action photo 405, and the fourth action photo 407 on one screen. In addition, at least some of the plurality of action photos can be output to one or more display modules 142. For example, when the display module 142 includes a first display module and a second display module, the first action photo 401 and the second action photo 403 can be output on the first display module. Similarly, the plurality of moving pictures taken by the plurality of camera units can be output to the display module 142 corresponding to the number.

In addition, the screen display sequence of FIG. 4 is not predetermined, and the screen combinations can be output on the display module 142 in various sequences.

In the embodiment of the present invention, when the player presets before the dart 111 hits the target Appearing in the pictures taken by the fourth camera unit for a period of time, the controller 190 will judge the throwing action of the dart 111 hitting the target as cheating. In detail, the controller 190 can recognize through the first camera unit 151 that the recognized player is standing at the throwing line 115. Although not shown in FIG. 4, a button and/or sensor can be installed on the throwing line 115. For example, when the player presses a button with his foot or is sensed by a sensor, the camera module 150 will start shooting. When the player enters the throwing line, the controller 190 will set the time from that moment (that is, the moment when the player presses the button with his foot or is sensed by the sensor) until the dart 111 hits the target 110, which is the aforementioned prediction. Set time.

In the dart game device 100 of this example, when the buttons and/or sensors installed on the throwing line 115 mentioned earlier sense the user input, the first to fourth camera units start to operate. Therefore, the number of camera units can be reduced. Electricity and/or data waste generated by continuous operation.

In addition, if the controller 190 in this example determines that a player (that is, someone other than the recognized player) appears in the picture taken by the fourth camera unit at a preset time, the controller 190 may determine that this example is cheating. In addition, if the controller 190 determines that at least a part of the player's body (that is, someone other than the player has been identified) appears in the picture taken by the fourth camera unit at a predetermined time, the controller 190 may determine that this example is cheating. In addition, the controller 190 may determine that when at least a part of the player's body appears in the picture taken by the third camera unit 153 (that is, a picture of the entire target) at a predetermined time, the controller 190 may determine that this example is cheating.

In another aspect of the present invention, the controller 190 can downsample the action photos received by the camera module 150 at a predetermined ratio. Downsampling represents the function that can reduce and generate the resolution of action photos. In addition, the controller 190 can select methods such as average sampling, bicubic downsampling, sub-sampling, etc., to reduce the quality of the received motion pictures. In addition, the aforementioned downsampling procedure will be executed by the host (that is, the host that determines the cheating) and the database host, not The dart game device 100. By performing downsampling, a large number of action photos can be stored in the memory 180.

FIG. 5 shows that the output module of the dart game device in the embodiment of the present invention sequentially outputs the action photos to the screen.

The screen depicted in FIG. 5 and the sequential output of action photos to the screen are only one embodiment of the present invention. Those skilled in the art should know that the scope of patent application of the present invention also includes screens with different shapes or different changes. In addition, although not shown in FIG. 5, the scope of patent application of the present invention is also included in other variables, information, and combinations thereof.

In an embodiment of the present invention, the display module 142 can output a plurality of action photos taken by a plurality of camera units on the screen in a predetermined sequence.

The controller 190 outputs a second motion picture 403 of at least a part of the player's body captured by the second camera unit 152 through the display module 142, which is used to verify whether the player throws the dart 111. For example, the controller 190 can recognize the player's face and verify the player's identity (as shown in FIG. 3).

In addition, the controller 190 can output the throwing line 115 taken by the first camera unit 151 and the first action photo 401 of the player's whole body on the display module 142. The first action photo 401 is an action photo of the throwing position and the throwing posture of the player throwing the dart 111. In addition, the first action photo 401 is taken to verify whether the player cheated when throwing the dart 111. For example, taking the first action photo 401 is used to verify whether the dart 111 thrown by the player exceeds the throwing line 115. In addition, the first action photo 401 can also be used to verify that the player does not exceed the throwing line 115 at a moment when throwing the dart 111, but only exceeds the throwing line 115 after throwing it. In this example, the fourth action photo 407 will be used to verify whether the player passes the throwing line 115 after throwing the dart. In addition, the first action photo 401 The function is to verify a situation (for example, whether to use a dart throwing device, etc.), and is not only used for the aforementioned cheating behavior.

Therefore, the controller 190 can sequentially output the third action photo 405 of the entire target taken by the third camera module 153 on the display module 142, and the fourth camera unit 154 between the throwing line 115 and The fourth action photo 407 of at least a part of the area between the dart game devices 100. Among them, the order of the third action photo 405 and the fourth action photo 407 can be changed. In addition, the first main action photo 405 and the fourth action photo 407 can be divided and displayed on the screen.
