| Abstract: Currently, recognition and counting of fitness pose are limited by factors such as the training of large models and the diversity of movement types, which often results in poor real-time performance, accuracy, and stability in fitness pose recognition and counting systems. The proposed system aims to address these shortcomings by using BlazePose for action recognition, thereby meeting the requirements of real-time and stable identification of fitness poses. The K-Nearest Neighbors (KNN) algorithm is employed to facilitate movement classification and counting. Additionally, Tkinter is used to realize an interactive interface, which enhances the system's interactivity. A noteworthy aspect of this system is its ability to perform pose recognition and counting functions with a minimal self-collected dataset. Test results demonstrate that the system achieves a count accuracy rate of 95.5% and real-time detection speed of 30 Frames per Second (FPS), making it suitable for broad applications in fitness venues and online fitness platforms. |
