Problems solved by technology

[0003] However, the traditional stereo matching algorithm has unavoidable mis-matching of some weak texture areas in the image, resulting in some road areas that are in contact with road objects (obstacles) being misdetected as foreground (obstacles), resulting in the final detected object Outlines and distances are inaccurate

Embodiment Construction

[0036] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0037] The stereo matching optimization method provided by this application can be applied to a vehicle intelligent driving system. The vehicle intelligent driving system involves an industrial computer and a camera. The industrial computer obtains the image to be matched captured by the camera, performs edge filtering on the image to be matched, and obtains each image point The gradient information and texture strength of the image are filtered out, and the stereo matching is performed after the weak texture image points are filtered out, and the disparity image obtained a...

Abstract

The present application relates to a stereo matching optimization method, device, computer equipment and storage medium. The method includes: acquiring the first image to be matched and the second image to be matched; determining the texture intensity of each image point according to the gradient information of each image point; removing the first type of image points in the first image to be matched to obtain The third image to be matched, the third image to be matched includes a second type of image point and a third type of image point; according to each image point in the third image to be matched and its corresponding image point in the second image to be matched , to obtain a parallax image, each image point in the parallax image corresponds to each image point in the third image to be matched; according to the texture intensity and parallax value of each image point in the parallax image, the third image point in the parallax image class image points for smoothing. Adopting the method can improve the ranging accuracy while maintaining the outline and continuity of the object.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular to a stereo matching optimization method, device, computer equipment and storage medium. Background technique [0002] Stereo vision has been widely used in intelligent driving scenarios. By performing stereo correction on the left and right images of the binocular camera, and then performing stereo matching, the 2D image can be converted into a 3D point cloud according to the camera parameters and the result of stereo matching, and then through the aggregation The class algorithm obtains the location information of obstacles. Obtaining a clear and continuous point cloud and accurate distance information are crucial for obstacle detection. [0003] However, the traditional stereo matching algorithm has unavoidable mis-matching of some weak texture areas in the image, resulting in some road areas that are in contact with road objects (obstacles) being misdetected ...
