Embodiment Construction
[0041] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0042] refer to figure 1 , is the flow chart of mine moving target tracking and positioning. First, use the multi-antenna radio frequency identification device to identify the target and obtain its current position coordinate information, and then use this information to guide the image sensor to turn on or sleep, and use the background difference method to detect the target in the video surveillance image and perform multi-view fusion to achieve more accurate positioning , and finally through the weighted fusion algorithm to fuse the two positioning results to obtain the location information of the moving target. The image sensor has an antenna module and a wireless interface function, and is used to receive communication instructions from the multi-antenna radio frequency identification device. The specific implementation steps are as fol...

The invention discloses a mine moving target tracking and positioning method. It is characterized in that it includes the following steps: (1) using a multi-antenna radio frequency identification device to identify the moving target in the coal mine and obtain its current location information; (2) using this information to guide the image sensor to turn on or sleep, and to detect (3) The location information of the moving object obtained by the multi-antenna radio frequency identification device and the location information of the moving object tracked and positioned by the image sensor are fused to obtain a location superior to that of a single positioning method. (4) If the image sensor does not monitor the moving target and cannot perceive its position information, a multi-antenna radio frequency identification device is used for identification and positioning. This method combines the advantages of multi-antenna radio frequency identification rapid positioning and accurate positioning of video images, which can effectively improve the real-time performance and accuracy of moving target tracking and positioning in coal mines.
Description
technical field [0001] The invention belongs to the coal mine underground positioning technology in the technical field of mobile communication, and in particular relates to a mine moving target tracking and positioning method which combines multi-antenna radio frequency identification and video positioning. Background technique [0002] Tracking and positioning of underground moving targets in coal mines is used to curb over-capacity production, prevent personnel from entering dangerous areas, emergency rescue for accidents, timely discovery of personnel who fail to ascend wells on time, management of leaders who go down the mine to lead shifts, management of special operators, attendance of underground operators, and management of on-the-job with certificates, etc. play an important role. [0003] Due to the large attenuation of wireless transmission underground in coal mines, GPS signals cannot cover the underground roadways of coal mines. At present, the position monito...
