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.
