Problems solved by technology
[0005] However, since there may be a heat source such as a streetlight shaped like a pedestrian's head around the vehicle, there may be a problem that even if the above-mentioned far-infrared camera is used, the artificial object such as the streetlight may be misdetected as a living thing such as a pedestrian. body

Embodiment Construction
[0020] Hereinafter, embodiments of the present invention will be described with reference to the drawings. figure 1 It is a block diagram showing the configuration of an apparatus for monitoring the surrounding conditions of a vehicle in an embodiment of the present invention. The device has: an infrared camera 1, the number of which is one, which is mounted on the vehicle and can detect far infrared rays; an image processing unit 2, which detects the monitored objects around the vehicle based on the image data captured by the camera 1 The type is judged; the speaker 3, which sounds an alarm based on the judgment result of the type; the head-up display (hereinafter referred to as HUD) 4, which is used to display the image captured by the camera 1, but also to display Alarm display made by judgment result. In addition, the above-mentioned device for monitoring the surrounding conditions of the vehicle further has: a lateral angular velocity sensor 6 for detecting the lateral ang...

A peripheral monitoring device for a vehicle of the present invention is mounted in a vehicle, performs image-capture of a periphery of the vehicle, and in the captured image, extracts an image area for which there is a possibility of corresponding to a predetermined section of a predetermined type of object for peripheral monitoring in order to set a predetermined area in the bottom of the extracted image area. On the basis of the predetermined area, candidates for a predetermined type of object that exist outside the vehicle are extracted, and for each of the extracted candidates for the object, an assessment is made as to whether the candidate for the object is the predetermined type of object. Here, if no pattern different from the background has been captured within the predetermined area, or if the predetermined area has been partitioned into first and second areas in the left and right directions, respectively, and a pattern different from the background has been captured in only one of the first and second areas, then the object within the image area corresponding to the predetermined area is excluded from the candidates for the predetermined type of object. In this manner, it is possible to distinguish, for example, a pedestrian from such an artificial structure as a street light so as to detect thereof.
Description
Technical field [0001] The present invention relates to a device for monitoring the surrounding conditions of a vehicle. More specifically, the present invention relates to a device that can easily and efficiently distinguish and detect the desired type of comfort when monitoring the surrounding conditions of the vehicle. Monitoring object. Background technique [0002] In the prior art, people have proposed a device for extracting various monitored objects existing around the vehicle. The following Patent Document 1 describes a method of measuring distance: a camera is mounted on a vehicle, and the area where the object to be monitored has less movement is set in the image captured by the camera It is a local area, and the distance from the vehicle to the monitored object is measured according to the change rate of the size of the local area over time. [0003] Patent Document 1: Japanese Invention Patent No. 4486997 [0004] In the above method, the upper body area of the pede...
