Lidar Essential Beam Model for Accurate Width Estimation of Thin Poles
Yunfei Long,Daniel Morris,Yunfei Long,Daniel Morris
While Lidar beams are often represented as rays, they actually have finite beam width and this width impacts the measured shape and size of objects in the scene. Here we investigate the effects of beam width on measurements of thin objects such as vertical poles. We propose a model for beam divergence and show how this can explain both object dilation and erosion. We develop a calibration method t...
