Problems solved by technology

However, when using this method, when the recognition of the same object is to be restarted due to the interruption of the detection of the object by the radar device, even if the detection of the object is restarted after the detection is interrupted, since it is determined that it has been detected multiple times in a row When the object is detected, the vehicle is controlled accordingly, which will also lead to the problem of delaying the corresponding control of the vehicle

Embodiment Construction

[0024] Hereinafter, an object recognition device according to an embodiment of the present invention will be described with reference to the drawings.

[0025] The object recognition device 10 according to the present embodiment is mounted on, for example, the vehicle 1 and is capable of recognizing objects (for example, pedestrians, other vehicles, structures, etc.) existing outside the vehicle 1 . Such as figure 1 As shown, the object detection device 10 has a radar device 11 , a camera device 12 and a processing device 13 .

[0026] A detection target area is set outside the vehicle 1, and the detection target area is divided into a plurality of angle areas at a certain angle. The radar device 11 emits radar waves as electromagnetic waves, and the radar waves scan in each angle area. The transmission waves emitted by the radar device 11 are reflected by objects outside the vehicle 1 (for example, pedestrians, other vehicles, etc.) to generate reflected waves, which are rec...

Abstract

An object recognition device (10) equipped with: a radar device (11) that detects objects in the vicinity of a vehicle (1); an imaging device (12) that detects objects by photographing the vicinity of the vehicle (1); and a processing device (13) that, when an object detected by the radar device (11) and an object detected by the imaging device (12) are present within a prescribed location range, recognizes that the objects are the same object. The processing device (13) recognizes that the object detected by the radar device (11) and the object detected by the imaging device (12) are the same object when both objects are present within the prescribed location range for a prescribed period of time. In addition, when the detection of an object by the radar device (11) or the imaging device (12) is interrupted and then the detection of an object begins again, the prescribed location range is narrowed or the prescribed period of time is reduced, after which the determination is made as to whether the objects are the same object.

Description

technical field [0001] The invention relates to an object recognition device. [0002] This application claims the priority of Japanese Patent Application No. 2013-142770 filed on July 8, 2013, and uses the content of the application here. Background technique [0003] There is a prior art device (see Patent Document 1) that detects pedestrians using a radar device and a camera mounted on a vehicle. [0004] Patent Document 1: Japanese Invention Patent Laid-Open Publication No. 2005-157765 [0005] However, in the device related to the above-mentioned prior art, in order to judge whether the object detected by the radar device and the object detected by the camera are the same object, a method of judging whether the object has been detected multiple times consecutively is used. method. However, when using this method, when the recognition of the same object is to be restarted due to the interruption of the detection of the object by the radar device, even if the detection...
