Image processing method and system for intelligent parking

Abstract

The invention discloses an image processing method and system used for intelligent parking. The method comprises the steps that environment images surrounding a target vehicle are acquired; overlooking transformation is conducted on the environment images, and corresponding overlooking environment images are obtained; the continuous mapping from the overlapping area of every two overlooking environment images to a closed disk is established according to the overlooking environment images; continuous functions on the closed disk are established according to the continuous mapping; and the overlooking environment images are fused according to the corresponding continuous functions. The environment images surrounding the target vehicle are transformed into the overlooking environment images, the continuous functions corresponding to the overlapping areas are established according to the overlapping area of every two overlooking environment images, horizontal and vertical gaps of the overlapping area of every two overlooking environment images can be eliminated at the same time, smooth transition is achieved, and a better image fusing effect is achieved; and when a driver parks the vehicle, excellent vehicle surrounding environment information can be provide for the driver, and the driver is assisted to safely and accurately park the vehicle at the positions of a parking space and the like.

Description

technical field [0001] The invention relates to the technical field of automobile intelligence, in particular to an image processing method and system for intelligent parking. Background technique [0002] With the development of the economy, great changes have taken place in people's lives. In order to save time and cost, many people choose to travel by car. [0003] With the increase in the number of people traveling by car, and the high population density of most cities in our country, this makes the parking spaces more and more compact. Accurately putting the car into the parking space or accurately parking the car has become a must-have skill for every driver. . However, there are often blind spots in the viewing angle during the reversing process, which causes the driver to encounter scratches during the reversing process.

Problems solved by technology

However, there are often blind spots in the viewing angle during the reversing process, which causes the driver to encounter scratches during the reversing process. In order to solve this problem, many vehicles are equipped with vehicle auxiliary safety reversing systems to integrate the surrounding environmental information of the vehicle. And the position information of the vehicle is fed back to the display screen in the car in the form of a top view, and the driver performs safe and accurate reversing and parking according to the prompts of the display screen

[0004] However, at present, the display screen of the auxiliary safety reversing system of the vehicle cannot display the environmental information around the vehicle very well. This is because the auxiliary safety reversing system often splices at least two images of the same scene to form a large scene image.

For example, the patent document whose application number is CN201110070860.9 discloses an image processing method and subsystem in a vehicle auxiliary system, which stitches the images, but only estimates the weight by the ratio of the distance between the pixel point and the two boundaries, This results in uneven transition of overlapping areas, so that there are still gaps in the image stitching process

This makes the display screen of the vehicle auxiliary safety reversing system unable to present the environmental information around the vehicle well, and cannot give the user a good visual effect.
