Embodiment Construction

[0044] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0045] The present invention is a visual detection method of underground belt deviation, such as figure 1 shown, follow the steps below:

[0046] Step 1. Read the real-time video stream of the underground belt:

[0047] Use the intrinsically safe camera to shoot down the underground belt, and transmit the image signal to the underground industrial computer through the switch. The edge of the belt in the real-time shooting image is parallel to the upper and lower boundaries of the image, and the starting point and end point of the belt in the image are the left and right sides of the image respectively;

[0048] When the present invention is used, the intrinsically safe camera shoots the edge of the belt vertically, the angle between the camera and the vertical direction is less than 10°, the vertical height between the camera and the belt is g...

Abstract

The invention discloses a visual detection method for the deviation of an underground belt, which is specifically implemented according to the following steps: 1. reading the real-time video stream of the underground belt; 2. processing the real-time video stream obtained in step 1 through two frame differences, and judging the belt Whether it is running; 3. Preprocess the real-time video stream to obtain the image-enhanced preprocessed image; 4. Calculate the belt offset coefficient; 5. Determine whether the belt is offset. The invention can avoid the occurrence of false detection caused by uneven material in the original detection method, quantify the belt offset coefficient, and improve the detection accuracy of the belt offset.

Description

technical field [0001] The invention belongs to the technical field of visual detection, and relates to a visual detection method for the deviation of a belt in a downhole. Background technique [0002] The underground belt system is an important part of coal mine production, and the premise of ensuring the stable production of the mine is to ensure the stable and reliable operation of the underground belt system. In actual production, the occurrence of belt deviation has caused severe challenges to downhole stability and safe production, and has become a common failure of downhole belt operation. How to detect whether the belt is offset in time and avoid secondary damage caused by the undiscovered belt offset, thereby reducing the economic loss of coal mining enterprises, ensuring the safe operation of underground personnel, and improving the stability of underground belt operation. [0003] The current detection method is mainly electronic detection method. Chinese patent...
