The multi-scale dual axial rotation laser image three dimension reconstruction system and the method thereof can solve the problem that non-angular points are difficult to reconstruct, and can be applied to multi-scale scope measurement.

Description

technical field [0001] The invention belongs to the technical field of image acquisition processing and three-dimensional reconstruction, and in particular relates to a multi-scale two-axis rotating laser image three-dimensional reconstruction system and method thereof. Background technique [0002] Three-dimensional reconstruction refers to the establishment of a mathematical model suitable for computer representation and processing of three-dimensional objects, which is the basis for processing, operating and analyzing its properties in a computer environment, and is also a key technology for establishing a virtual reality that expresses the objective world in a computer . [0003] An important function of 3D reconstruction of the scene is to obtain the 3D information of the scene. In traditional 3D reconstruction, corner extraction is often used for 3D reconstruction, but for objects without obvious corner points, its 3D reconstruction is difficult to achieve. In additi...
