Abstract

An object recognition device includes: a radar that detects objects in the vicinity of a vehicle a camera that detects objects by capturing an image of the vicinity of the vehicle an identical object recognition unit configured to recognize that an object detected by the radar and an object detected by the camera are the same object when the objects are present within a predetermined position range. The identical object recognition unit determines whether the objects are the same object by reducing the predetermined position range when detection using the radar device or the camera is interrupted and then detection is started again.

Claims

1. An object recognition device comprising:

a radar that detects objects in the vicinity of a vehicle;

a camera that detects objects by capturing an image of the vicinity of the vehicle; and

an identical object recognition unit configured to recognize that an object detected by the radar and an object detected by the camera are the same object when the objects are present within a predetermined position range,

wherein the identical object recognition unit determines whether the objects are the same object by reducing the predetermined position range when detection using the radar or the camera is interrupted and then detection is started again.

2. The object recognition device according to claim 1, wherein the identical object recognition unit gradually increases the predetermined position range when the same object is not present after the predetermined position range is reduced.

3. The object recognition device according to claim 1, wherein the identical object recognition unit recognizes that the object detected by the radar and the object detected by the camera are the same object when the objects are present within the predetermined position range for a predetermined period of time, and determines whether the objects are the same object by reducing the predetermined position range when detection using the radar or the camera is interrupted and then detection is started again.

4. The object recognition device according to claim 3, wherein the identical object recognition unit gradually increases the predetermined position range when the same object is not present after the predetermined position range is reduced, and changes the predetermined period of time with an increasing trend along with an increase of the predetermined position range.

6. The object recognition device according to claim 2, wherein the identical object recognition unit recognizes that the object detected by the radar and the object detected by the camera are the same object when the objects are present within the predetermined position range for a predetermined period of time, and determines whether the objects are the same object by reducing the predetermined position range when detection using the radar or the camera is interrupted and then detection is started again.
