The invention discloses a multi-view vehicle data recorder, a target detection method, and intelligent driving system and an automobile. The multi-view vehicle data recorder comprises a wide-angle camera, a binocular stereo camera, an image analysis processor and a memory, wherein the wide-angle camera and the binocular stereo camera are respectively used for acquiring wide-angle images and stereoimages of targets in front of automobiles; the image analysis processor is used for carrying out target detection on the stereo images so as to obtain target distance information of the detected targets, and re-projecting the detected targets in the stereo images into the wide-angle images according to an image registration result between the wide-angle images and the stereo image so as to obtaintarget recognition information of the detected targets. According to the multi-view vehicle data recorder, advantages of the binocular stereo camera are utilized to obtain relatively correct detectedtargets and target distance information, the detected targets in the stereo images are re-projected into the wide-angle images so as to display the target recognition information of the detected targets, so that the multi-view vehicle data recorder has both the advantages such as wide view of the wide-angle camera and correct distance measurement of the binocular stereo camera.
Description
Technical field [0001] This application relates to the technical field of automobile assisted driving, in particular to a multi-camera vehicle recorder, a target detection method, an intelligent driving system and an automobile. Background technique [0002] The current vehicle-mounted recorder includes a camera and a vehicle-mounted terminal. The camera is generally installed in front of the vehicle body and collects road images in front of the car through the camera. The vehicle-mounted terminal detects obstacles on the road in front of the car through the road image collected by the camera and sends out warnings to the driver. [0003] At present, vehicle recorders include wide-angle camera-based vehicle recorders and binocular stereo camera-based vehicle recorders. Among them, vehicle recorders based on wide-angle cameras mostly use a camera with a wide-angle lens optical system, which has a large viewing angle and small blind areas. It has become the mainstream solution of the...
