摘要

投影仪-激光雷达系统在使用激光雷达校准投影仪后对远距离物体进行投影映射。使用配备RGB摄像头的激光雷达，用户只需两次扫描即可校准投影仪。由于该系统知道从投影机拍摄的每个像素的光线公式，因此可以进行准确的投影。特别是，该系统介绍了如何在获得公式的过程中进行线性插值，以及使用户能够立即知道所需部件在二维图像中的三维坐标的方法。通过远距离实验，所提方法的投影映射结果误差小于5mm，现有系统最大误差为30mm。

Projection Mapping Method Using Projector-LiDAR (light detection and ranging) Calibration

The projector-LiDAR system performs projection mapping on a long-distance object after calibrating the projector using LiDAR. With LiDAR equipped with an RGB camera, users can calibrate the projector in just two scans. Because this system knows the ray formula for every pixel shooting from the projector, it can make accurate projections. In particular, the system introduces how to perform linear interpolation in the process of obtaining a formula and a methodology that allows users to immediately know the 3D coordinates of a desired part in a 2D image. Through a long-distance experiment, the projection mapping result of the proposed method showed an error of less than 5mm, and the existing system had a maximum error of 30mm.
