Abstract

The application discloses a homonymous point matching method comprising the following steps: a plurality groups of images that are obtained after images of a target object are collected via a plurality of image collection modules are acquired, each group of images among the plurality groups of images are subjected to photometric normal direction calculation operation, normal direction images for each group of images are obtained, point cloud images that respectively correspond to all the normal direction images are obtained, a point cloud image set is obtained, homonymous point matching operation is performed via use of the point cloud image set, and a three dimensional homonymous point matching relation is obtained; according to the three dimensional homonymous point matching relation, amapping relation between corresponding point cloud data and image pixel points is determined, a homonymous point matching relation of corresponding images is determined via use of the three dimensional homonymous point matching relation and the mapping relation, and a two dimensional homonymous point matching relation is obtained. Via the method disclosed in the invention, a high accuracy homonymous point matching relation which is accurate in conversion is obtained. Based on the homonymous point matching method, the application discloses a corresponding homonymous point matching system, a three dimensional reconstruction and system and a photometric stereo shooting terminal.

Description

technical field [0001] The invention relates to the field of photometric stereo matching, in particular to a homonymous point matching and three-dimensional reconstruction method, system and photometric stereo camera terminal. Background technique [0002] Photometric stereo technology is a method of 3D surface reconstruction in order to obtain 3D models quickly and accurately. Using the method of photometric stereo vision to calculate the surface normal vector and recover the 3D surface information from the surface normal vector is a simple and fast 3D reconstruction algorithm, which is widely used in 3D game modeling and interactive animation. Among them, photometric stereo matching is an important step in 3D reconstruction. Through photometric stereo matching of multiple groups of images, stereoscopic image information is obtained to perform 3D reconstruction. [0003] The same-named point matching algorithm used in the prior art is not ideal enough to make accurate reg...
