Object detection system and object detection method

Abstract

The present invention provides an object detection system and object detection method, the object detection system comprising: a light emitting portion, it is used as a two-dimensional pattern of light emitted to the object; scanning block light, which is used in the space continuously by a predetermined change the emission direction of light as a two-dimensional pattern scanning operation is performed; light reflector, it is attached to a predetermined position on the object to be detected as imposed, and for the two-dimensional pattern light in the form of the opposite to the emission direction of the two-dimensional pattern has a light reflection direction; the reflected light detecting unit, which is for detecting the reflected light reaches the reflector and the light becomes the reflected light detecting portion light; and a reflective optical analysis unit, which based on a signal representing the reflected light of the reflected light is detected by the detecting unit, calculates the vertical angle of the light reflector and the horizontal-direction angle. The system and method of the present invention can be simpler and more accurate detection of the moving object.
