[0070] Such as Figure 4 As shown, the method for taking pictures with a camera for a fully mechanized mining face according to the first embodiment of the present invention includes steps S101 to S103, and each step is described in detail as follows:

[0071] Step S101, collecting the actual motion information of the shearer.

[0072] In this embodiment, the mining camera is installed inside the top beam of the hydraulic support, and the shearer includes a left drum (front drum) and a right drum (rear drum), and the left drum and the right drum drive the shearer as a whole to move left and right. Mobile coal mining, that is, the motion states of the left drum, the right drum and the shearer as a whole in the embodiment of the present invention are consistent. Due to the large length of the shearer, the mining camera can monitor the motion state of the entire shearer by monitoring the motion state of the left or right drum of the shearer. Specifically for this step, during t...

[0081] On the basis of the first embodiment, the second embodiment can also adjust the shooting angle of the mining camera in combination with the position information of the coal mining machine, so as to further improve the video monitoring effect.

[0082] see Figure 5 , the second embodiment of the fully mechanized mining face mine camera follow-up shooting method includes the following steps:

[0083] Step S201, acquiring the position information of the left drum or the right drum of the coal mining machine, and acquiring the actual movement information of the left drum or the right drum of the coal mining machine.

[0084] In the second embodiment, during the moving coal mining process of the shearer, the mining camera information acquisition module acquires the position information of the left drum or the right drum of the shearer, the left drum or the right drum of the shearer collected in real time by the information transmission system. Information such as the movin...

[0098] During the left and right movement of the shearer, if the hydraulic support moves forward, the focal length between the mining camera and the shearer drum that needs to be monitored will continue to change, which will affect the mining camera's shooting of the shearer drum. clarity. Based on this, the difference between the third embodiment and the above-mentioned first embodiment and the second embodiment includes: Aiming at the situation that the hydraulic support moves forward during the left and right movement of the shearer, a mining camera is provided to automatically The method of focusing.

[0099] see Figure 6 In the following, the method for taking pictures with the video camera of the fully mechanized mining face according to the third embodiment will be described in detail. Include steps:

[0100] Step S301, acquiring the position information of the left drum and the right drum of the coal mining machine, the actual movement information of the left drum ...

Abstract

The invention relates to a mining camera following shooting method and system for a fully mechanized coal mining face. The mining camera following shooting method includes: collecting actual motion information of a coal cutter; analyzing an image shot by the mining camera, thereby obtaining monitoring motion information of the coal cutter contained in the image; and analyzing deviation of the monitoring motion information from the actual motion information, and adjusting the shooting angle of the mining camera according to the deviation. Through the scheme of the invention, in an underground leftward and rightward movement production process of the coal cutter, the mining camera can automatically perform real-time following shooting on the coal cutter in the fully mechanized coal mining face, the problem of a shooting dead angle in a coal mining process of the coal cutter is eliminated, and system cost of coal cutter video monitoring is reduced.

Description

technical field [0001] The invention relates to the field of fully mechanized mining monitoring, in particular to a method and system for monitoring the state of a fully mechanized mining face with a mine camera and a camera. Background technique [0002] At present, with the continuous improvement of the national fully-mechanized mining automation construction level, the country pays more attention to the safety of coal mine personnel and production equipment, and the coal shearer, as the most important production equipment in the fully-mechanized mining face, must be monitored by the underground coal mine video surveillance system. equipment. Such as figure 1 , 2 As shown, the fully mechanized mining face usually includes a shearer, a mining camera, a hydraulic support and an information transmission system. The mining camera is installed on the inside of the top beam of the hydraulic support. The camera performs real-time video tracking of the coal shearer. [0003] I...
