Binocular three-dimensional reconstruction method and binocular three-dimensional reconstruction system

Abstract

The invention discloses a binocular three-dimensional reconstruction method and a binocular three-dimensional reconstruction system. The binocular three-dimensional reconstruction method includes acquiring certain portions of a person or an object on a turntable by the aid of two cameras; turning the turntable by a circle to obtain three-dimensional point cloud data of the scanned object and reconstructing three-dimensional curved surface models of the scanned object; driving a 3D (three-dimensional) printer to carry out printing so as to obtain three-dimensional models of the measured object. The acquired certain portions of the person or the object on the turntable are irradiated by line infrared light. The core thoughts include that the position of the to-be-measured object on the turntable is corrected by a line laser device, so that the to-be-measured object can be positioned in the center of a rotary shaft; an industrial personal computer is connected with two cameras to acquire the portions, which are irradiated by the line infrared light, of the measured object, and the turntable rotates at the constant speed by the circle under the control of the industrial personal computer; acquired images are extracted by an infrared center, and point cloud data can be generated; binocular point cloud data are fused and denoised; curved surfaces are reconstructed according to the fused point cloud data; the three-dimensional models of the measured object are printed. The binocular three-dimensional reconstruction method and the binocular three-dimensional reconstruction system have the advantages that the person or the object can be three-dimensionally reconstructed, the three-dimensional models of the person or the object can be printed, the binocular three-dimensional reconstruction method and the binocular three-dimensional reconstruction system are speedy and stable and are high in precision, and application requirements on quickly acquiring three-dimensional models of measured objects can be met.

Description

technical field [0001] The invention belongs to the technical field of machine vision three-dimensional reconstruction and model processing, and in particular relates to a binocular three-dimensional reconstruction method and system. Background technique [0002] 3D reconstruction has been one of the important research fields of computer vision. In recent years, the research on 3D reconstruction technology has made great progress, and the 3D models constructed by it have been used in various fields such as model processing, clothing manufacturing, medical imaging, cultural relics protection, film and television special effects, and computer games. At present, the 3D reconstruction methods based on computer vision can be divided into passive and active methods according to the lighting conditions. The passive method does not provide an additional light source, and only collects and processes images through the camera under natural light conditions. It is mainly divided into ...

Problems solved by technology

The point structured light method can only measure the three-dimensional information of one point on the target at a time, and it takes too long to measure the entire three-dimensional information of the target, and the efficiency is low, which is not conducive to practical application; although the line structured light method can obtain one light bar on the target at one time All three-dimensional information, but there is a camera blind spot problem; although multi-line structured light can avoid the camera blind spot problem and improve image processing efficiency, it increases the complexity of calibration and the light bar matching problem
