<p>The serving action of volleyball will affect the result of the match, but the conventional evaluation method is difficult to accurately evaluate the quality of serving only through naked eye observation. Therefore, this paper tries to develop a volleyball service evaluation system based on optical processing and image recognition, and studies the application of optical processing technology in the volleyball service evaluation system, so as to improve the objective evaluation and analysis ability of volleyball service quality. Firstly, optical processing technology is used to process the video of volleyball serving process, and the key information of serving action is extracted by image recognition algorithm. Then, the extracted information is compared with the preset standard, and the volleyball serving quality is evaluated by evaluation algorithm. By analyzing the experimental results of a large number of volleyball service videos, the system can accurately identify and evaluate the quality of volleyball service, which has certain reliability and accuracy compared with the manual evaluation results, and can effectively improve the evaluation and analysis ability of volleyball service quality, and provide certain support for volleyball training and competition.</p>
