Embodiment Construction

[0052] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0053] The present invention is a shadow removal method of pothole image, such as figure 1 shown, including the following steps:

[0054] S1. Collect road surface pictures through the visual acquisition system, obtain images containing potholes, and construct the original data of the pothole data set: the visual acquisition system is fixed on the hood of the car, such as figure 2 As shown in , use the Open CV toolbox function to obtain the video frame containing potholes from the captured video;

[0055]The visual acquisition system includes a monocular camera or a binocular camera. The monocular camera uses image matching for image recognition, and then estimates the d...

Abstract

The invention discloses a method for removing shadows of pothole images, comprising: S1, collecting road surface pictures through a visual collection system, acquiring images containing potholes, and constructing raw data of pothole data sets; S2, processing pothole data sets Raw data is grayscaled; S3, performing shadow detection on the grayscaled image, and segmenting it into shadowed areas and non-shadowed areas; S4, using an improved shadow removal model on the segmented image to remove the shadowed area; solving It is easy to misdetect shadows and potholes in grayscale image processing, and the shadow removal effect needs to be improved, which affects the safe and stable driving of smart vehicles.

Description

technical field [0001] The invention relates to the technical field of image information processing of intelligent vehicles, in particular to a shadow removal method for pothole images. Background technique [0002] With the rapid economic growth, intelligent vehicles are becoming more and more widespread. In order to ensure the safe and stable driving of intelligent vehicles, machine vision and image processing technology are generally used to determine obstacles and distance measurement in front of intelligent vehicles; in the image processing process In the process, the image is often converted into a grayscale image and then preprocessed, but the grayscale characteristics of the shadow are very similar to those of the potholes, and it is very likely that the shadow is misdetected as a pothole, or the pothole is mistakenly detected as a shadow , affecting the shadow removal effect, causing unnecessary actions of the intelligent vehicle, or affecting the safe and stable dr...
