Color coding greatly improves the measurement efficiency of structured light three-dimensional(3D) measurement system. However, chromatic aberration (CA) reduces the measurement accuracy of the system. In this study, the lateral chromatic aberration (LCA) of camera and projector is analyzed by experiments, and the optimization model of LCA is studied according to the analysis results. Based on the study, a compensation method of system LCA is proposed. The simulation results show that the compensation method is feasible, and the experimental results prove that the proposed method can effectively reduce the measurement error caused by LCA.

结构光3D测量系统的横向色差分析与补偿

彩色编码大大提高了结构光三维（3D）测量系统的测量效率。但是，色差（CA）会降低系统的测量精度。本研究通过实验分析相机和投影仪的横向色差（LCA），并根据分析结果研究LCA的优化模型。在此基础上，提出了系统LCA的补偿方法。仿真结果表明，该补偿方法是可行的，实验结果表明，该方法可以有效降低LCA引起的测量误差。
