Human body posture estimation method and system based on multiple view angles

The invention belongs to the technical field of human body posture estimation, discloses a multi-view-angle-based human body posture estimation method and system, and provides a lightweight and efficient multi-view-angle three-dimensional human body posture estimation method. The method follows a two-stage processing thought, firstly, a two-dimensional joint point heat map of each view angle is estimated for a multi-view-angle posture, and then a three-dimensional human body posture is reconstructed according to the two-dimensional heat map, so that the complexity of a model is effectively reduced, and the real-time detection performance and action classification of a system are improved. According to the method, epipolar constraints in multi-view geometry are utilized to align and fuse heat maps of the same articulation point in different view angles, and the accuracy and geometric consistency of a two-dimensional attitude estimation result are further improved on the premise of not increasing learning param
