import numpy as np

定义 2D 关键点数组

key_points_a = np.array([[1,2], [3,4], [5,6], [7,8]]) key_points_b = np.array([[9,10], [11,12], [13,14], [15,16]])

计算每帧的骨骼中心

center_a = np.mean(key_points_a, axis=0) center_b = np.mean(key_points_b, axis=0)

计算偏移量

offset = center_b - center_a

将每帧的骨骼中心对齐

key_points_b_aligned = key_points_b + offset
