Problems solved by technology
[0003] At present, there are two methods for detecting the straightness of scraper conveyors: one is to use ultrasonic sensors or sensing optical fibers to determine the straightness of scraper conveyors. It is easy to fail, and the straightness cannot be measured normally after failure
The other is to detect the running track of the shearer through the positioning sensor, and to detect the straightness of the scraper according to the relationship between the shearer and the scraper. This method is costly

The disclosure relates to a method for detecting the straightness of a scraper conveyor based on video recognition. The method includes: acquiring an image of the area where the scraper conveyor is located; identifying the scraper conveyor in the image and its instance segmentation; extracting the outer contour coordinate value of the scraper conveyor in the image; Calculate the linear correlation coefficient; if the calculated linear correlation coefficient is less than the preset threshold, it is judged that the straightness of the scraper conveyor does not meet the requirements. The scheme provided by this disclosure can use the image data of the scraper conveyor to obtain the straightness of the scraper conveyor through image recognition, avoiding the problem of detection failure caused by the damage of the sensor during use. At the same time, the hardware structure required by the method Simple, the price cost is more appropriate.
Description
technical field [0001] The present disclosure relates to the fields of image recognition and coal transportation machinery, in particular to a method and device for detecting the straightness of a scraper conveyor based on video recognition. Background technique [0002] According to the "Coal Mine Safety Regulations", the coal wall, scraper conveyor and hydraulic support of the coal mining face must be kept in a straight line. The scraper conveyor is used as the track of the shearer, and its straight line directly affects the straight line of the coal wall of the coal mining face and the service life of the shearer, coal mining efficiency and coal cutting quality. Therefore, it is very important to ensure the straightness of the scraper conveyor, and the research on the straightness detection technology of the scraper conveyor is an important measurement tool to ensure the straightness of the scraper conveyor. [0003] At present, there are two methods for detecting the st...
