Abstract
A laser scanning sensor includes a laser range finder, a scanning mechanism, a data acquisition portion, a dirt determination portion, an alert output control portion and a memory. The laser range finder is arranged inside a housing having an opening portion, and the opening portion is covered with a lens cover that can transmit laser light. In the dirt determination portion, a predetermined threshold to be compared with a received light level is changed based on maximum detection distance information in each measurement direction.
