摘　　要：研究了三维激光彩色扫描仪中获得物体表面色彩信息的方法．针对装置特点，研究了在彩色扫描图像序列中，物体表面采样点在激光入射面和相机主光轴面的成像对应关系，提出了利用采样点在相机主光轴面的像获得色彩信息的方法，有效地克服了传统结构光测距装置中由于结构光源照射带来的色彩失真和物体表面复杂而造成侧面遮挡的影响．Acquirement of color information of the objects surface in three dimension laser color scanner is explored. The relationship between the sample points image in the laser plane and its image in the main optics axis plane are studied. A new method is presented which obtains color information from the image in main optics axis plane. Two problems in traditional structure light system can be solved, one is that colr is changed by laser, the other is invisible because of side occluding.
