Problems solved by technology

[0003] 1) Due to the different textures of the parking lot, some sites will be more reflective, and the scattered light strips will seriously affect the extraction of parking space lines
[0004] 2) Some parking lots are dark (such as underground parking lots), and the parking spaces are not clear
[0005] 3) Due to the influence of dust on the camera or the noise of the camera itself, there are more noise points in the image, which affects the detection of parking spaces

Abstract

The invention provides an image preprocessing method and an image preprocessing system for parking spot detection. The method comprises the following steps: acquiring a parking spot scene image, wherein the reflective part of a parking spot scene is displayed in the parking spot scene image; and processing the parking spot scene image using a defogging algorithm, thus highlighting the information about the parking spots in the parking spot scene image and reducing the influence of the reflective part on parking spot detection. Problems, for example, light reflection of a site affects parking spot line extraction, parking spots are not clear in a dark environment, and an image has many noisy points due to adverse factors of a camera, can be solved effectively. The efficiency and accuracy of parking spot detection in an image are improved.

Description

Technical field [0001] The invention relates to the field of image processing, in particular to an image preprocessing method and system for parking space detection. Background technique [0002] The environment of the parking lot is more complicated, especially the underground parking lot. In the surround view image, it is extremely difficult to accurately detect the parking space due to the distortion of the angle of view. The quality of the collected image has a great influence on the vision-based parking space detection. In the image of the parking lot environment, the main factors that affect the parking space detection are as follows: [0003] 1) Due to the different texture of the parking lot, the reflection of some sites will be more serious, and the scattered light strip seriously affects the extraction of parking spaces. [0004] 2) Some parking lots are very dark (such as underground parking lots) and the parking spaces are not clear. [0005] 3) The dust on the camera or...
