Abstract 

The speech will first introduce the main achievements of our team in the Minis-try of Science and Technology's Project “CoachAI” in the past four years, special-izing in how data were extracted from the match video. In the next stage, to real-ize the automated badminton shot collection and promote related data applica-tions, we have participated in the AI CUP competition under the topic of "Teaching Computer to Watch Badminton Matches", hoping to popularize the research and application of badminton tactics analysis.
