摘要: 针对发光二极管（LED）技术和成像通信分析技术的成熟发展，结合井下人员定位系统定位精度的需求，提出了一种基于可见光通信与摄像仪图像采集分析技术的煤矿井下人员定位方法。该方法利用井下防爆摄像仪采集LED矿灯的可见光信号图像,识别与矿灯绑定的矿井人员编码信息；利用可见光图像识别算法，确定矿井人员的位置信息，定位矿井人员。试验验证表明:系统定位误差不大于0.4 m，响应时间不大于0.368 s，该定位方法能够有效提高位置定位精度和实时性。Abstract: Aiming at the mature development of light-emitting diode （LED） technology and imaging communication analysis technology, combined with the requirement of positioning accuracy of underground personnel positioning system, a coal mine underground personnel positioning method based on visible light communication and camera image acquisition and analysis technology is proposed. The method uses the underground explosion-proof camera to collect the visible light signal image of the LED miner’s lamp, and identifies the mine personnel coding information bound with the miner’s lamp, uses the visible light image recognition algorithm to determine the position information of the mine personnel and locate the mine personnel. The experimental results show that the system positioning error is not more than 0.4 m and the response time is not more than 0.368 s. The positioning method can effectively improve the positional positioning accuracy and real-time performance.
