Abstract:

Human pose estimation usually uses a single RGB image to locate the key points of human body to estimate the position of human body and joint points. Ball games are usually regarded as fast sports, and errors cannot be avoided in judging the technical legitimacy of players by subjective observation. Therefore,based on the estimation of human body posture, the athlete posture analysis technology is used to assist training and penalty. This method effectively avoids the traditional system positioning the athlete posture due to human subjective judgment error. At present, the research of human pose estimation can be divided into traditional algorithm and deep learning algorithm. Based on the deep learning algorithm, it can be divided into single person pose detection and multi person pose detection.Through the construction of neural network,human pose estimation based on deep learning algorithm uses machine learning method to extract image features and read image information,and perform performance comparison and analysis on mainstream data sets for human pose estimation. The application of human body posture estimation in ball games can provide scientific reference for athletes' daily training, and also ensure the fairness and justice of athletes in the game to the greatest extent.

Key words: human pose estimation, video recognition, ball game, key point positioning, feature extraction, neural network, target detection, supplementary training
