Research on the Scoring Algorithm of Throwing Effect Based on Visual Motion Sensing Technology

Vision-based human-computer interaction technology, namely visual motion sensing technology, has made many application achievements. In terms of entertainment, there are many pioneering applications. Aiming at the combination of visual motion sensing technology and throwing game, this paper studies the throwing scoring algorithm of the motion sensing throwing target system for entertainment.In RGB-D target detection, get the detection frame coordinates of the face and hand at the end of the throwing, extract the depth information of the center point of the detection box, calculate the movement speed of the center point of the hand at the end of the throwing, compared with the lowest throwing speed, determine whether the throwing missed the target, and the distance between the center point is calculated, and the accuracy of the throwing is judged according to the distance of the two. A difficulty coefficient is designed according to the distance of the throw, comparing the difficulty coefficient to the number of cycles in last throw are multiplied to give the final score. The effectiveness of the algorithm is verified by comparing experiments with real throwing situations.
