Problems solved by technology

When the alarm or automatic brake is activated in a place where there are no pedestrians due to false detection, it will become a troublesome system for the driver and the reliability will decrease
[0006] In particular, when automatic braking is activated because there is no object (non-stereoscopic object) that is dangerous for the vehicle to collide with, it will put the vehicle in a dangerous state and impair the safety of the system

Embodiment Construction

[0054] Hereinafter, the first embodiment of the present invention will be described in detail with reference to the drawings. figure 1 It is a block diagram of the environment recognition device 1000 for a vehicle in the first embodiment.

[0055] The outside world recognition device 1000 for a vehicle is installed in the camera 1010 mounted on the car, or in the centralized controller, etc., and is used to detect a preset object from the image captured by the camera 1010. Detect pedestrians in the image ahead.

[0056] The external environment recognition device 1000 for a vehicle is constituted by a computer having a CPU, memory, I / O, etc., and predetermined processing is programmed, and the cyclic processing is executed at a predetermined cycle. Vehicle external recognition device 1000, such as figure 1 As shown, it has an image acquisition unit 1011, a processing area setting unit 1021, a pedestrian candidate setting unit 1031, and a pedestrian determination unit 1041. A...

Abstract

Disclosed is an environment recognizing device for a vehicle, capable of reducing false detection of artifacts such as utility poles, guardrails, and markings painted on road surfaces with a small processing load during detection of pedestrians using pattern matching. Specifically, the environment recognizing device comprises an image acquiring unit (1011) that acquires an image in front of the vehicle in which the device is installed; a processing-region setting unit (1021) that sets processing regions for detecting pedestrians from the image; a pedestrian-candidate setting unit (1031) that sets pedestrian candidate regions for determining the presence of pedestrians from the image; and a pedestrian determining unit (1041) that determines whether the pedestrian candidate regions are pedestrians or artifacts in accordance with rates of amounts of change in tones in predetermined directions within the pedestrian candidate regions.

Description

technical field [0001] The present invention relates to an external environment recognition device for vehicles that detects pedestrians based on information captured by imaging elements such as vehicle-mounted cameras. Background technique [0002] In order to reduce the number of casualties caused by traffic accidents, the development of preventive safety systems to prevent accidents before they happen is being developed. In Japan, accidents in which pedestrians die account for about 30% of the total number of traffic accident deaths. In order to reduce such pedestrian accidents, a preventive safety system that detects pedestrians in front of the vehicle is effective. [0003] The preventive safety system is a system that works in situations where the possibility of an accident is high. For example, when there is a possibility of collision with an obstacle in front of the vehicle, an alarm is used to prompt the driver to pay attention, and when a collision is unavoidable, ...
