Active three-dimensional reconstruction system and method based on linear structured light rotation scanning

Abstract

The invention discloses an active three-dimensional reconstruction system and method based on linear structured light rotation scanning. The system comprises an image acquisition module, a rotary table motion module, a rotary table motion control module, an image processing module, a three-dimensional coordinate calculation module, a data transmission and reading module and a display module. The image acquisition module is arranged on the rotary table motion module, the rotary table motion module is connected with the rotary table motion control module, and the rotary table motion control module controls the rotary table motion module to rotate. The method can reconstruct and measure the three-dimensional shape information of the to-be-measured target, and has the characteristics of reasonable structure, high adaptability, high reconstruction precision and the like. Compared with a traditional three-dimensional reconstruction system based on a translation slide rail, the system adopts a rotary acquisition mode, so that the equipment size is smaller, the occupied space during operation is smaller, and a mechanical jitter error introduced in a traditional linear translation process can be effectively avoided.

Problems solved by technology

Surface structured light can generate more information on the object surface at the same time, but the matching of multiple light bands will bring a huge amount of system calculation, and the complexity of system calibration will be greatly increased, and the overall workload of the system is much larger than that of the line structured light method.
