Abstract

The invention discloses a cuboid automatic detection and three-dimensional reconstruction system and method. The system comprises a driving displacement module, a laser scanning module, a texture acquisition module, and a central processing module. The driving displacement module comprises a multi-axis stepping motor driver, an X-axis translation table, a Y-axis translation table, a Z-axis translation table, a rotation table, and an objective table. The laser scanning module is disposed over the objective table and is used for acquiring the laser point cloud of the surface of a to-be-tested cuboid. The texture acquisition module is disposed on the Z-axis translation table and is used for acquiring the texture image of the surface of the to-be-tested cuboid. The central processing module is connected with the multi-axis stepping motor driver, the laser scanning module, and the texture acquisition module. The cuboid automatic detection and three-dimensional reconstruction system and method achieves automation in laser point cloud acquisition analsysis, image capturing and processing, and three-dimensional model reconstruction, may rapidly achieve the automatic detection and three-dimensional texture reconstruction of the cuboid, and solves low efficiency and large work intensity in the prior art.

Description

technical field [0001] The invention belongs to the technical field of three-dimensional reconstruction, and in particular relates to a system and method for automatic detection and three-dimensional reconstruction of a rectangular body. Background technique [0002] In the field of aerospace, it is necessary to detect and archive the shape information of some important cuboid parts in the spacecraft. For convenient and fast detection, rich and intuitive archives, the present invention designs and implements a system for automatically detecting and reconstructing three-dimensional models of cuboid parts based on the non-contact measurement technology of three-dimensional reconstruction. The 3D reconstruction technology based on computer vision refers to restoring the geometric outline information of space objects from multiple 2D images. The actual on-line inspection using 3D reconstruction technology has the advantages of non-contact, good flexibility, high precision, fast...
