Wavefront measurement-based target object depth information acquisition method

Abstract

The invention discloses a wavefront measurement-based target object depth information acquisition method. The method uses a wavefront measurement device to measure the wavefront information of target object point radiation spherical waves, and then the sphere center of the spherical waves is calculated according to wavefront, and thus, the space position of the target object point is obtained. As the space target object can be regarded to be formed by discrete matter points one by one, when the wavefront measurement device completes position calculation on all target object points, the depth information of the whole space target object can be acquired. The method adopts a wavefront measurement method in physical optics to acquire the depth information of the target object, the complicated traditional geometric optics and projective geometric calculation methods are got rid of, and a foundation is laid for digital holographic recording and display of the space target object.

Description

technical field [0001] The present invention relates to the technical field of object depth information acquisition, in particular to a method for acquiring object depth information based on wavefront measurement. Background technique [0002] In the field of computer vision, the technology of obtaining the depth information of the target has attracted the attention of scientific researchers. The acquisition of depth information can not only enable the robot to better recognize human expressions, gestures and body movements in order to realize human-computer interaction, but also enable the robot to autonomously locate space targets and build maps, so as to improve the intelligence level of the robot. Therefore, the device and method for depth acquisition have broad application prospects in fields such as game entertainment, medical treatment, and education. At present, the existing relatively mature depth information acquisition technologies include stereo vision technolog...
