Problems solved by technology

[0004] The present invention mainly solves the technical problem that the splicing seams in the mosaic diagram of the vehicle in the top view displayed by the existing vehicle-mounted 360-degree surround view system are constantly changing and unstable due to noise when the surrounding environment of the vehicle does not change, and provides a vehicle-mounted 360-degree surround view The display method and system, when the stitching seams at a certain position have little difference in adjacent time sequences, the stitching seams of the previous frame are reused, which greatly reduces the influence of

Embodiment

[0067] Embodiment: a kind of vehicle-mounted 360 degree look-around display method of the present embodiment, the front side, the rear side, the left side, the right side of the car are respectively provided with a camera, as figure 1 The following steps are shown:

[0068] S1: The projection module transforms the viewpoint of the image collected by each camera through the lookup table, and projects it to the top view of the vehicle;

[0069] The lookup table stores the nonlinear mapping relationship from the bird's-eye view coordinate system to each camera coordinate system, see formula (1); the pixel coordinates of the camera image corresponding to each pixel in the bird's-eye view are obtained through the look-up table, and then interpolated (such as double-line The value of each pixel in the top view can be obtained by way of linear interpolation), and the determination of the lookup table can be obtained by calibrating the internal and external parameters of each camera (...

Abstract

The invention discloses an onboard 360-degree around-viewing display method and system. The method comprises the following steps of: S1, enabling a projection module to subject images acquired by respective cameras to viewpoint transformation by looking up a lookup table and to project the images onto a vehicle top view; S2, subjecting the four camera images to optical alignment by using an exposure gain algorithm; S3, splicing the splicing seams of the images acquired by the adjacent cameras by using a splicing algorithm to obtain the vehicle top spliced view. The method reuses the splicing seam of a last frame when the splicing seam at a certain position is not large in adjacent timing sequential difference so as to reduce an influence of noise on the calculation of the splicing seam greatly for improving stability. In addition, the direct use of the splicing seam of the last frame also shortens the calculation time of splicing seam and improves algorithm efficiency.

Description

technical field [0001] The present invention relates to the technical field of vehicle-mounted surround view, in particular to a vehicle-mounted 360-degree surround-view display method and system. Background technique [0002] The car's 360-degree surround view system is one of the driving assistance functions. This system can display the surrounding conditions of the vehicle (including some short-range blind spots) to the driver under low-speed conditions. The existing 360-degree surround view system generally installs a camera on the front, rear, left, and right of the car body. Each camera collects data within the field of view, and then integrates the collected images through the processing unit, and fuses the overlapping parts to form a The 360-degree panorama is output and displayed on the display screen. [0003] When the vehicle-mounted 360-degree surround view system splices the images collected by the front, rear, left, and right cameras of the vehicle body, it ne...
