Laser triangulation range finder available under direct sunlight
Proceedings. 1988 IEEE International Conference on Robotics and Automation, 1988 The authors have developed a laser range finder (LRF) which enables a mobile robot to measure the distance to a natural object located 1-5 m ahead with an error less than 2%. The system uses a laser as weak as 1 mW, a safe level for human eyes, and is workable under bright daytime sunlight of about 100000 lx. This LRF can quickly process data and makes
