On-vehicle device and recognition support system

Abstract

The invention relates to an on-vehicle device and a recognition support system, capable of achieving cost reduction of the on-vehicle device and allowing a driver to reliably recognize the presence of a detected moving object while preventing detection omission of a moving object approaching an own vehicle from a blind corner for the driver. The on-vehicle device includes an imaging unit that captures an image of a wide angle range through a curved light receiver, a moving-object detector that detects a moving object approaching an own vehicle from a mounting direction of the imaging unit and from any direction other than the mounting direction, based on the image captured by the imaging unit, a collision-risk determination unit that determines a degree of collision risk indicating a possibility of collision between the moving object detected by the moving-object detector and the own vehicle, and a moving-object warning unit that warns presence of the moving object according to the degree of collision risk .

Description

technical field [0001] The present invention relates to an in-vehicle device and a cognitive support system mounted on a vehicle. In particular, the cost of the in-vehicle device can be reduced, and the omission of detection of a moving object approaching the own vehicle from the driver's blind spot can be prevented. An in-vehicle device and a cognitive support system for a driver to reliably recognize the presence of a detected moving object. Background technique [0002] In recent years, a large number of vehicle-mounted devices have been developed that detect moving objects around the vehicle from images captured by cameras and sensors, and report danger when the own vehicle and the moving object are likely to come into contact. [0003] For example, Patent Document 1 discloses an in-vehicle device that detects an obstacle that may come into contact with the own vehicle from images captured by a plurality of on-vehicle cameras mounted on a vehicle such as a motor vehicle,...

Problems solved by technology

[0008] However, the vehicle-mounted device of Patent Document 1 requires a plurality of vehicle-mounted cameras, and there is a problem that the cost required for the vehicle-mounted cameras increases.

[0009] In addition, since the vehicle-mounted device of Patent Document 2 displays the left and right images side by side on the display device, there is a problem that it is difficult for the driver to grasp the sense of distance between the left and the right.

[0010] In addition, in the vehicle-mounted camera of the vehicle-mounted device of Patent Document 2, images on the left and right sides are captured, but images in the front are not captured.

That is, since the front of the vehicle-mounted camera is a blind spot, it is impossible to detect an approaching vehicle with a high possibility of danger to the own vehicle.

Therefore, the front safety confirmation must be corrected within the driver's field of vision, but it is difficult to cover this blind spot only with the driver's field of vision
