Abstract

The invention discloses a binocular visual sense reconstruction method considering three-dimensional distortion, belonging to the computer visual sense measurement technology field. The binocular visual sense reconstruction method considering the three-dimensional distortion introduces a three-dimensional distortion correction function to perform compensation optimization on a visual sense reconstruction result and realizes three-dimensional high accuracy remodeling. The binocular visual sense reconstruction method considering the three-dimensional distortion adopts a traditional binocular visual sense reconstruction method to obtain a three-dimensional reconstruction initial values of measurement points, solves a three-dimensional distortion compensation value on the basis of a relative relation between a standard object and a binocular camera and the reconstruction initial values, thus performs distortion compensation on coordinates of the camera of a tested point which are respectively extracted from a left image and a right image, combines with binocular visual sense theory to reconstruct, and realizes the binocular three-dimensional high accuracy reconstruction. The binocular visual sense reconstruction method considering three-dimensional distortion is high in reconstruction accuracy, can compensate the three-dimensional distortion of the binocular visual sense, realizes form and surface reconstruction of a part having a big curvature and a big size and improves three-dimensional reconstruction accuracy of the binocular visual sense.

Description

technical field [0001] The invention belongs to the technical field of computer vision measurement and relates to a binocular vision reconstruction method considering three-dimensional distortion. Background technique [0002] Binocular machine vision has the advantages of non-contact, multi-information, and fast measurement, and has been widely used in the measurement of aerospace and aviation large parts. The reconstruction process is an important link to realize the spatial three-dimensional field measurement of binocular vision. However, in the traditional binocular vision reconstruction, only the distortion change in the plane range is considered, and the three-dimensional concept of depth distortion is introduced. Therefore, in the depth direction Measurement accuracy is poor. However, due to the large size of aerospace parts, the three-dimensional size is large, and the geometric quantity changes in the depth direction are also large, therefore, the realization of th...
