Picture synthesis calibration method

Abstract

The invention discloses a picture synthesis calibration method, and relates to the field of automobiles. The picture synthesis calibration method achieves safe driving of the automobiles. The picture synthesis calibration method comprises the steps that a first point coordinate of any one point is obtained and recorded while a rearview mirror camera is unfolded; a relation between the first point coordinate and an identical world point coordinate is built and recorded; a relation between a pixel value and the first point coordinate of the same point in a first distortion picture is obtained through an internal parameter model and recorded; a relation between the pixel value and the world point coordinate of the same point in the first distortion picture is obtained and recorded; a second point coordinate of any one point is obtained and recorded while the camera is folded; a relation between the second point coordinate and the first point coordinate of the same point is built and recorded; a relation between the pixel value and the second point coordinate of the same point in a second distortion picture is obtained through the internal parameter model and recorded; a relation between the pixel value and the world point coordinate of the same point in the second distortion picture is obtained and recorded. The picture synthesis calibration method is applied to an automobile safety system.

Description

technical field [0001] The invention relates to the field of intelligent safe driving of automobiles, in particular to an image synthesis calibration method. Background technique [0002] With the development of society, cars have entered every household, and people are paying more and more attention to the safety performance of cars. The intelligent safety driving system of cars has become a development trend. [0003] In the actual driving process, because the car driver cannot know the surrounding environment at the same time, it is easy to cause accidents such as scratches and bumps. Therefore, the current car intelligent safety driving system can provide the driver with a 360-degree panoramic view around the car to facilitate driving. Operators perform operations such as safe parking. Among them, the imaging system consists of four wide-angle cameras and a controller. The front camera is installed on the front bumper, the rear camera is installed on the rear license pl...
