Color multi-line laser 3D measurement method based on laser MEMS galvanometer projection

The invention discloses a color multi-line laser 3D measurement method based on laser MEMS galvanometer projection. The measurement method comprises the following steps: multiple color line lasers encoded in different colors are generated through a computer; the color line lasers are projected by a laser MEMS galvanometer projection system; deformed color line lasers on a measured object are shot using a color camera, and the multiple line lasers in different colors are distinguished according to color tone; and multiple frames of images are scanned and shot by a laser MEMS galvanometer projection device, and the images are reconstructed and combined later to get the 3D shape of the object. 本发明公开了种基于激光MEMS振镜投影的彩色多线激光三维测量方法。该测量方法用计算机生成多条不同颜色编码的彩色线激光，利用激光MEMS振镜投影系统对其进行投射；用彩色相机拍摄被测物体上的变形彩色线激光，根据色调区分不同颜色的多条线激光；通过激光MEMS振镜投影装置快速扫描拍摄多帧图像，后期重建组合得到物体三维形貌。
