Abstract

The invention discloses an area array structure optical system-based three-dimensional reconstruction method and system. The method comprises the following steps that: the projection plane coordinatesof a projector in a projection coordinate system are obtained according to the physical coordinates of the projector and the calibration parameters of the projector; the first camera plane coordinates of a camera in a camera imaging coordinate system are obtained according to the physical coordinates of the camera and the calibration parameters of the camera, and the first camera plane coordinates are converted to the projection coordinate system, so that the second camera plane coordinates of the camera in the projection coordinate system can be obtained; the forward projection view and reverse projection view of an acquired image are obtained, and a target area is encoded according to the difference image of the forward projection view and the reverse projection view; the point cloud image of the target area is obtained according to the projection plane coordinates and the second camera plane coordinates, and a depth image is generated according to the point cloud image; and three-dimensional reconstruction is performed on a target object according to the point cloud image and the depth image. The method of the embodiments of the invention has the advantages of high precision and high efficiency of three-dimensional reconstruction.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a three-dimensional reconstruction method based on an area array structured light system. Background technique [0002] Three-dimensional images are used more and more. Usually, a 3D image is obtained by converting a 2D image. At present, there are many conversion technologies. However, some conversions have low precision and some conversion efficiency is low, thus affecting the application of 3D images. SUMMARY OF THE INVENTION [0003] The present invention aims to solve one of the above-mentioned technical problems in the related art at least to a certain extent. [0004] Therefore, an object of the present invention is to propose a three-dimensional reconstruction method based on an area array structured light system, which has the advantages of high three-dimensional reconstruction accuracy and high efficiency. [0005] Another object of the present invention is...
