The invention provides a barrier distance discrimination image generation method and device, and relates to the field of driving safety. The method comprises the steps: selecting a first image material and a second image material, carrying out the wire frame analysis of the first image material, obtaining an initial contour line of a target feature object which faces a vehicle tail angle from a cab of a vehicle, carrying out the error adjustment of the initial contour line according to the external scene features of the vehicle window features and the second image material, obtaining a real contour line of the target feature object which faces the vehicle tail angle from the cab of the vehicle, finally enabling the second image material to be overlapped with the real contour line, and generating a barrier distance discrimination image. According to the invention, the method and device are advantageous in that the method and device enable a driver to more accurately judge the distance between an object behind the vehicle and the vehicle through a display screen.
Description
technical field [0001] The present invention relates to the field of driving safety, in particular to a method and device for generating an obstacle distance judging image. Background technique [0002] In the process of driving, in order to increase the field of vision behind the car, more and more cars have added cameras behind the car, and then the pictures taken by the rear camera are displayed on the display screen in the car, so that the driver can conveniently and intuitively to see the image behind the car. [0003] However, although the driver has seen the image behind the car through the display screen, the driver does not know where the car or pedestrian in the image behind the car is relative to his own car, which may cause the driver to misunderstand the position of the object behind the car. judgment, accidents may occur. [0004] How to solve the above problems is the key point that those skilled in the art need to pay attention to. Contents of the inventi...
