Complement of missing data in LiDAR Measuremen

Abstract

In LiDAR measurement, measurement loss caused by laser reflection not returning is called black spot. A black spot occur when a laser is irradiated on a specular reflection material or a material with a high absorption rate of infrared rays, in many cases, laser reflections are obtained from around the black spot. Conventionaly, in object recognition using LiDAR measurement, only measured data has been used. However, since LiDAR actively irradiates the laser, we thought that black spots also contained information for object recognition. Therefore, we propose a complement method of black spots in LiDAR measurement Moreover, we confirmed through several experiments that the pedestrian recognition accuracy improves by applying the proposed method.
