[0027] See also Figure 1 The present invention provides a technical solution: a portable digital Tang ball device based on visual recognition, comprising:

[0028] Camera 1, which collects and visually processes high-speed images of the Tang ball and the target position;

[0029] Infrared sensor 2, which detects the presence of Tangqiu;

[0030] An embedded main control 3, which is electrically connected to the camera 1 and the infrared sensor 2, and the embedded main control 3 obtains data and signals from the camera 1 and the infrared sensor 2, and the embedded main control 3 performs visual processing on the obtained data to obtain Tang ball flight data and performs game logic processing;

[0031] A communication module 4, which is electrically connected to the embedded main control 3, and the communication module 4 supports the embedded main control 3 to perform network communication with the outside;

[0032] A plurality of peripheral interfaces 5, which are electrically connected to the embedded main control 3, and the plurality of peripheral interfaces 5 are used to connect a display device, an external storage device and an audio device;

[0033] A power module 6, which is electrically connected to the embedded main control 3, and the power module 6 supplies power to all devices;

[0034] The camera 1 is a high frame rate industrial camera to ensure high-quality image acquisition;

[0035] The embedded main control 3 uses an ARM&L i nux embedded system, has sufficient computing power and resources, and supports image processing and data analysis;

[0036] The communication module 4 is an M.2 wireless network card, which supports network communication and LAN online battle functions;

[0037] The plurality of peripheral interfaces 5 are HDMI interface, USB interface and AUX interface, which expand the game function and interactivity;

[0038] The power module 6 is a 12V DC power supply, which is adapted to the voltage requirement of the infrared sensor 2. The 12V DC power supply converts the voltage into 5V DC through a step-down module. The 5V DC is used to power low-voltage devices such as the embedded main control 3. In addition, the power on and off status of the system can be controlled by a button, with instant power-on and delayed power-off.

[0039] Working principle: First, the infrared sensor 2 is used as a trigger switch to aim at the position where the Tang ball is placed to identify whether the Tang ball is hit. After the infrared sensor 2 is triggered, subsequent work such as video acquisition is started to reduce the working pressure of the system. The OpenCV image processing library is used to identify the hitting point. The video collected by the camera 1 is processed by setting a dynamic threshold and an HSV mask to realize the position recognition of the Tang ball and the target in the image. Subsequently, the image is denoised using graphics processing methods such as corrosion and expansion to enhance the stability and accuracy of recognition. After visual recognition, the position of the Tang ball in the image is obtained, and the frame displacement of the Tang ball is calculated by frame-by-frame difference, and the displacement data is smoothed by applying algorithms such as low-pass filtering. According to the speed change, it is determined whether the Tang ball interacts with the target, and then the position information of the Tang ball when it contacts the target is obtained. Finally, the position of the target recognition point in the image is mapped to the target coordinate system through perspective transformation to obtain the transformation matrix. The position of the hitting point is converted from the image coordinate system to the target coordinate system using the transformation matrix to realize the precise positioning of the hitting point on the target.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
