Problems solved by technology

[0003] For example, at night or in a backlight environment where there are both bright areas and dark areas within the camera's field of view, the dynamic range of the camera is insufficient and overexposure or underexposure may occur, which may result in the inability to use images to identify objects

Embodiment Construction

[0029] Next, embodiments of the present invention will be described below using the drawings.

[0030] figure 1 It is a structural diagram of the vehicle-mounted environment recognition device. The vehicle-mounted environment recognition device in this embodiment utilizes the vehicle-mounted camera in the vehicle to photograph the surrounding environment of the own vehicle to recognize obstacles, lane markings and other surrounding environments. In this case, it is possible to sound an alarm or perform vehicle controls such as emergency braking. The vehicle-mounted environment recognition device is constituted, for example, by a combination of hardware and software such as a camera device. As its internal functions, such as figure 1 As shown, it has an imaging unit 100 , an irradiation area setting unit 200 , an observation unit 300 inside an irradiation area, an observation unit 350 outside an irradiation area, an inside and outside exposure adjustment unit 400 , an identif...

Abstract

An onboard environment recognition device is obtained with which it is possible to improve recognition performance within the headlight illumination range and outside the headlight illumination rangeof a vehicle with an onboard camera. This onboard environment recognition device has: an imaging unit 100 for imaging, using a camera installed in the vehicle, at a wider-angle range than the headlight illumination range; an in-illumination / out-of-illumination exposure adjustment unit for setting appropriate exposure conditions separately within the headlight illumination range and outside the headlight illumination range; and a recognition unit 500 for recognizing images on the basis of the acquired images. Therefore, it is possible to maintain high recognition performance in the boundary regions of the headlight illumination range, and outside the range, and the present invention can also be used for wide-angle sensing at night.

Description

technical field [0001] The present invention relates to a vehicle-mounted surrounding environment recognition device that uses a vehicle-mounted camera to recognize obstacles, lane markings, etc. that exist around a self-vehicle. Background technique [0002] Commercialization of applications for recognizing the surrounding environment of the self-vehicle from a camera installed in the vehicle tends to increase. Among them, applications in preventive safety technologies that use recognized objects to prevent accidents before they happen, and vehicle control technologies that aim at autonomous driving are expected by the industry. Recognition technology for vehicle control requires high reliability. [0003] For example, at night or in a backlight environment where there are both bright and dark areas within the camera's field of view, the dynamic range of the camera is insufficient and overexposure or underexposure occurs, which may result in the inability to recognize obje...
