Automobile panorama round-looking system realized by small-angle cameras

Abstract

The invention discloses an automobile panorama round-looking system realized by small-angle cameras, and relates to a technology applied to the field of automobile electronics and the field of active safety auxiliary driving of automobiles. The automobile panorama round-looking system comprises six or more cameras (including at least four ordinary cameras), mounting brackets corresponding to each of the cameras, a video capture and image processor host machine with six or more camera interfaces, a displayer, a function shifting switch and a connecting wire harness. According to the automobile panorama round-looking system disclosed by the invention, the problems that in the prior art, four wide-angle cameras are adopted, and the distortion degree of peripheral parts is high, so that the clarity is insufficient, and the implementation effect of the four wide-angle cameras on a big vehicle with a long vehicle body is poor are effectively solved. According to the automobile panorama round-looking system disclosed by the invention, the ordinary cameras are adopted, so that the number of sensed integral pixels of images is increased; the distortion degree is low, so that the number of the effective pixels is increased, and the clarity of the images is improved; and through a special mounting manner, the situation that objects in the periphery of the vehicle cannot disappear can be guaranteed, and a farther and greater displaying range in the periphery of the vehicle is obtained.

Description

[0001] Technical field: [0002] The invention belongs to the field of automotive electronics technology, and is also an active and safe auxiliary driving technology for automobiles. Used to assist the car driver to observe the situation around the vehicle when the vehicle is driving or reversing. [0003] Background technique: [0004] Existing panoramic car parking systems generally consist of 4 wide-angle cameras, image processors, and in-cab displays. The 4 wide-angle cameras are located at the front, rear, left, and right positions of the car. Generally, the front wide-angle camera is installed on the front grille of the car, the rear wide-angle camera is installed on the back door of the car, and the left and right wide-angle cameras are installed in the left and right rearview mirrors, respectively. The video signals collected by the 4 cameras are sent to the image processor, and the video images are corrected and spliced ​​through the image processing algorithm to form a bi...

Problems solved by technology

However, the geometric distortion of the camera itself is between 50% and 90%, and the distortion near the edge is very high. The overall image has a fisheye effect, and image correction will reduce the clarity of the overall image during image processing;

[0008] (2), the image splicing part is blurred and unclear:

[0009] Due to the high geometric distortion of the image collected by the edge part of the wide-angle camera itself, the image splicing part generally corresponds to the edge part of the camera, so the image definition of the splicing part is very poor;

[0010] (3), for vehicles with a longer body length, the image definition is too poor with the existing scheme:

[0015] (3) Since the number of cameras is different and the degree of distortion of the cameras is different, the required image processing techniques are different;
