Technical Field

[0001] The invention belongs to the field of sensors, and in particular, relates to a laser scanning sensor testing system and a testing method. Background Art

[0002] Laser scanning sensors are widely used in various fields, especially with the widespread popularization of intelligent equipment. For example, smart factories, intelligent transportation, autonomous driving, and smart devices all use laser scanning sensors.
