Abstract
The present invention provides an object detection apparatus for detecting at least one object existing in an observation subject space. The object detection apparatus comprises an object model recording unitthat calculates and records an object model, which is an image expressing the form of a detection subject, a millimeter wave distance sensorthat calculates the distance to an object candidate by emitting millimeter waves so as to cover the entirety of the observation subject space at one time, a stereo image sensorthat calculates a characteristic image and a distance image having different viewpoints, a control unitthat selects an object candidate, a model conversion unitthat calculates a comparison model from the object model, a comparison image extraction unitthat extracts a comparison image from the characteristic image and distance image, and a similarity comparison unitthat calculates the similarity between the comparison model and comparison image, and when a maximum similarity is within a predetermined range, calculates the three-dimensional position of the object from the coordinates of the comparison image and the distance to the object candidate, and outputs the three-dimensional position of the object to the outside.
