Abstract
As a three-dimensional reconstruction method, the structured light formed by multiple reflection of neutral beam splitter mirror can effectively solve the problem caused by high reflectivity. In order to obtain more stripes, the jittering mechanism is used in the system. In addition, the linear algorithm can not make full use of the information between different structured light, which will produce a large error and inaccurate result. To solve this problem, we propose a correlation algorithm. In this algorithm, we use two structured light as the independent variables to obtain spatial information, and a related items is calculated to take full advantage of the information between different structured light. Experimental results show that the overall measurement error is reduced by 20-30% and the repetition accuracy of the system reaches 0.02 mm.
