Problems solved by technology

[0003] There is a sprinkler detection method, which first extracts the foreground object in the road image, and then further judges whether the extracted foreground object is a sprinkler. This sprinkler detection method is easily affected by factors such as light and image position, and its accuracy is relatively low. Low

Embodiment Construction

[0033] In order to make the above objects, features and advantages of the present invention more comprehensible, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0034] In order to facilitate the understanding of the technical content and advantages of the present invention, two different detection methods for road spills are firstly introduced. One is the road spill detection method based on foreground detection. First, the background is extracted according to the road image, and the foreground object is extracted on this basis, and then the extracted foreground object is further judged whether it is a spill. The stickiness is poor, because the real road conditions are very complex, different light intensities, shadow occlusion, etc. will seriously affect the detection results of this method. The other is a road spill detection method based on a machine learning algorithm. This method requires a l...

Abstract

The present invention provides a method for detecting road spills, computer equipment and storage media. The method for detecting road spills includes: acquiring an image to be detected; identifying a vehicle from the image to be detected based on a preset target detection algorithm, and obtaining Including a first image sub-block and a second image sub-block of the vehicle, the area of ​​the second image sub-block is larger than the area of ​​the first image sub-block; extracting the foreground object in the second image sub-block, Generate a third image sub-block containing the foreground object; calculate the similarity between the third image sub-block and the first image sub-block; when the similarity is less than or equal to a preset value, determine that there is a spilled object . The invention can accurately judge whether there are road throwing objects.

Description

technical field [0001] The invention relates to the technical field of computer vision, in particular to a method for detecting road spills, computer equipment and a storage medium. Background technique [0002] With the rapid development of urban roads, road safety has become a key issue that cannot be ignored in the traffic field. Spilled objects are one of the main reasons for threatening road safety. If abnormal spilled objects on the road are not cleaned up in time, they will cause serious safety hazards. Therefore, it is necessary to judge whether there are spilled objects on the road, and notify the staff to clean up on the spot in time. [0003] There is a sprinkler detection method, which first extracts the foreground object in the road image, and then further judges whether the extracted foreground object is a sprinkler. This sprinkler detection method is easily affected by factors such as light and image position, and its accuracy is relatively low. Low. Conten...
