Example Embodiment

[0041] The present invention will be described in detail below with reference to the drawings and specific embodiments.

[0042] Reference figure 1 , Is the flow chart of mine moving target tracking and positioning. First, the multi-antenna radio frequency identification device is used 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 Finally, the two positioning results are merged by a weighted fusion algorithm to obtain the location information of the moving target. The image sensor has an antenna module and a wireless interface function, which is used to receive communication instructions from a multi-antenna radio frequency identification device. The specific implementation steps are as follows:

Abstract

The present invention discloses a mine mobile object tracking and location method. The method comprises the following steps: (1) employing a multi-antenna radio frequency identification device to perform identity identification of a mobile object in coal mine and obtain current position information of the mobile object; (2) employing the information to guide the starting or dormancy of an image sensor, detecting the mobile object in the video monitoring image and capturing the current position information; (3) performing information fusion processing of the mobile object position information obtained by the multi-antenna radio frequency identification device and the mobile object position information of tracking and location of the image sensor to obtain the mobile object position information being better than that through usage of a single location method; and (4) if the image sensor does not monitor the mobile object and cannot sense the position information of the mobile object, employing the multi-antenna radio frequency identification device to perform identification location. The mine mobile object tracking and location method fuses the advantages of rapid location of multi-antenna radio frequency identification and accurate location of video images so as to effectively improve the timeliness and accuracy of tracking and location of the mobile object in the core mine.

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...
