Abstract

The invention discloses a belt motion state monitoring method based on video processing, and belongs to the technical field of motion detection. The method comprises the following steps: firstly, preprocessing a video, and then detecting a moving object; setting a zone bit according to the area of a motion area in the video, and judging whether the belt in the current video frame is dynamic or static; defining a state machine to realize dynamic conversion of four motion states of the belt, and then judging the state of the current video frame according to the flag bit and the accumulated valueof the flag bit, so that the motion state of the belt is judged and an alarm is given in real time. According to the invention, the non-contact detection of the belt is realized, the normal operationstate and the no-load operation state of the belt can be judged and distinguished, the support of a laser emitter and hardware equipment is not needed under the condition of ensuring the accuracy ofthe detection result, and the implementation cost of monitoring the motion state of the belt is reduced.

Description

Technical field

[0001] The present invention belongs to the technical field motion detection, and more particularly the belt state monitoring method based on motion video processing. Background technique

[0002] Due to the special conditions of production of coal, ore transport belt as the material of important equipment, the production status of their work is critical to mine safety. Intelligent motion mine belt condition monitoring, maintenance to reduce labor costs, improve mine safety production has a significant meaning.

[0003] A conventional belt motion state monitoring method, the detection is generally based on a method of image processing hardware, or video-based technique. For example, the patent CN201610970736, based on the obtained logical data and ultrasonic ranging belt speed and whether meandering of the belt, but such monitoring hardware-based method, when applied to relatively harsh production environments, such as underground coal mines and the like, can easi...
