A UAV video perception system for tracking coal shearers

Abstract

Provided is an unmanned plane video sensing system for tracking a coal cutter. The unmanned plane video sensing system comprises multiple four-rotor aircrafts, an infrared emitter, a coupler, and a computer. The aircrafts are equipped with cameras and controllers. The infrared emitter is arranged on the coal cutter and used for determining the spatial position of the coal cutter. The coupler is arranged on a working face and is used for forming a WLAN and communicating with the aircrafts via a wireless routing function. The computer is connected with the coupler through an Ethernet. The automatic unmanned plane tracking technology is applied to working face of a coal mine. A large number of cameras on the working face in the prior art are replaced by a few cameras so that cost is saved, cables are saved, and dense wire arrangement is prevented. The method uses little equipment so as to reduce latent fault points. The unmanned plane achieves following camera shooting, and adjustable distance and angles. Images captured by the unmanned plane are clearer than those captured by conventional cameras so as to achieve high flexibility and continuousness without switching. The system may achieve an unmanned plane sleep mode controlled by a controller, saves electric energy, and achieves a long time of endurance.

Description

technical field [0001] The invention relates to an unmanned aerial vehicle video perception system, in particular to an unmanned aerial vehicle video perception system for tracking an underground coal mining machine in a coal mine. Background technique [0002] The shearer is one of the most important equipment in the fully mechanized mining face, and its normal operation is the basis for the entire fully mechanized mining face to complete the mining operation. Therefore, the monitoring of the shearer is an important task in the fully mechanized mining face of the coal mine . In the past, the condition of the shearer drum and the surrounding roof and floor of the fully mechanized mining face has been visually inspected manually, and then adjusted according to the actual situation, which is laborious, poor in accuracy, and very unsafe. [0003] With the continuous advancement of fully mechanized mining technology, camera technology has been introduced underground in coal min...

Problems solved by technology

However, it can only monitor one target, and the target has no movement or a single movement mode. There are no strict requirements for the calibration method of the movement of the UAV, and it cannot be used in the harsh environment of the underground, nor can it be used for complex movement modes and numerous monitoring targets.
