摘要：采用线结构激光和一个彩色CCD摄像机构成三维彩色扫描系统，彩色CCD摄像机分两次对物体成像，首先摄取物体的彩色图片，然后利用滤光镜摄取激光光平面上物体的三维信息。最后采用彩色贴图技术将两次获取的信息重叠，便可得到物体的三维彩色信息。提出了激光光平面方程式三维测量方法，建立了相应的数学模型。进行了实验研究，给出了实验结果。

Abstract：The three dimensional colorful reverse engineering presented in this paper is composed of one line-strip laser and one colorful CCD camera.The scanned object is pictured twice by colorful CCD camera.First，the texture of scanned object is taken by colorful CCD camera.Then the three dimensional information of scanned object is obtained from laser plane equations by adding the filter to CCD camera.This paper presents model using laser plane equations and get pretty good result af-ter experiment verify.

Keywords：reverse engineering three dimensional colorful scanning laser scanning optic plane equations
