<p>In the course of physical education teaching, the traditional teaching methods are often faced with problems such as the difficulty in providing accurate, timely and intuitive data feedback. Therefore, by utilizing real-time data simulation technology of heterogeneous sensors and embedded image system, more accurate and intuitive teaching feedback is provided to improve the teaching effect. The principle and characteristics of sensor and embedded image system are studied and analyzed, and the corresponding experimental platform is built. A series of PE teaching experiments are designed and implemented to provide real-time and accurate teaching feedback by collecting and analyzing the data obtained by sensor and image system. The experimental results show that the real-time data simulation technology using heterogeneous sensor and embedded image system can significantly improve the effect of physical education. Through intuitive data feedback, students are able to have a deeper understanding of the correctness and optimization direction of actions, and make timely adjustments and improvements. Teachers are also able to assess student performance more comprehensively and provide individualized instruction to different students.</p>
