Embodiment Construction

[0064] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0065] The present invention is a method for real-time positioning and identification of coal gangue on the ground movement belt, such as figure 1 As shown, it specifically includes the following steps:

[0066] Step 1, the data set is established; the data set is continuously photographed by a 2-megapixel camera for 7*24 hours, and the belt is hand-selected in the coal building of the fourth mine of Pingdingshan Tianan Coal Industry Co., Ltd. The size of the coal gangue is mainly concentrated in the range of 80-300mm, and the shooting angle is used to look down. The vertical distance between the camera and the hand-selected belt is about 50-100cm, and the xml file is generated after labelme labeling, and the final labeled images are more than 3000.

[0067] The specific process of step 1 is, see figure 2 ;

[0068] Step 101, data set dat...

Abstract

The invention discloses a real-time coal gangue positioning and identifying method for a ground moving belt. The method specifically comprises the following steps: step 1, establishing a data set; 2,training a target detection model; step 3, real-time image acquisition: transmitting the real-time images of the coal gangue on the ground moving belt to an industrial personal computer through a wired network camera to process real-time video streams; 4, extracting a model detection real-time video, and counting the types of target objects in the real-time video; and step 5, calculating the sizeof the coal gangue and determining the relative position based on the target object category determined in the step 4. The coal gangue on the moving belt is identified by adopting the image, so that the problem of environmental pollution caused by a ray method is solved.

Description

technical field [0001] The invention belongs to the technical field of image processing, and relates to a method for real-time positioning and identification of coal gangue on a ground motion belt. Background technique [0002] In the mining process of coal mining enterprises, gangue with different ash content on the coal face is transported to the coal building through the belt transportation system. Workers use experience to detect whether the target object on the belt is coal or gangue, and manually classify the detection results. With the development of sensor technology and image processing technology, how to automatically detect coal gangue targets in real time, locate and classify targets, and digitize the target information on the moving belt has become a problem that needs to be considered. At the same time, how to convert the detected pixel information into physical information, so as to facilitate feedback or storage for subsequent feedback devices and storage dev...
