Human body positioning method based on multi-perspectives and lighting system

Abstract

A human body positioning method based on multi-perspectives includes simultaneously capturing pictures from at least two perspectives angles and extracting human body feature points, matching the human body feature points of a same human body of a same position in different pictures to form matched point groups and calculating 3D coordinates of corresponding 3D point of each matched point group in a 3D space, further calculating and weighting spatial geometric error between the 3D point and each human body feature point of the corresponding matched point group in each original picture to obtain reprojection error of the 3D point, and subsequent to projecting each 3D point onto the ground to obtain single-point 2D coordinates thereof on the ground, weighting the projected single-point 2D coordinates according to the reprojection error of the corresponding 3D point to obtain a projection distribution of the corresponding human body on the ground.
