Object recognizing device

摘要

An object recognizing device for recognizing an object by transmitting laser light from a laser light source and receiving reflected light from the object by a light sensor, wherein the laser light source and the light sensor are disposed at a relative vertical distance of not less than 20 cm therebetween with a divergence angle theta 1 of the laser radiation emitted from the laser light source being set at a value of not more than 5 mrad and being smaller than an angle alpha formed between an optical axis of the laser light and an optical axis of the reflected light entering into the light sensor, and which is, therefore, capable of effectively recognizing any object even in an atmosphere containing aerosol, e.g., fog or haze.
