Abstract
Disclosed are a method for capturing three dimensional actions of multiple persons, a storage media and an electronic device. The method includes: obtaining synchronous video frames of multiple cameras, recognizing and positioning joint points in each synchronous video frame of each camera, to obtain two dimensional (2D) joint point of each person in each camera; calculating an anti-projection ray of each 2D joint point, and clustering coordinates of two endpoints of a shortest distance between two anti-projection rays to obtain a 2D personnel matching scheme, wherein the anti-projection ray is from a camera pointing to its corresponding 2D joint point; and performing a three dimensional (3D) reconstruction for each person according to the 2D personnel matching scheme, to generate 3D information of each person for capturing 3D actions.
