Embodiment Construction
[0015] The present invention is based on the beam transmitting and receiving system of white light LED, utilizes the long and narrow space in the traffic tunnel to establish a top-down multi-receiver sensing system with an opaque plate, and sets a center vertically upward on the top of the positioning object (unmanned aerial vehicle). LED light source with fixed irradiation and divergent irradiation angle range. Collect the graphic data of different incident angles and different projected areas formed by the same LED light source and opaque plate on multiple receivers, and establish a basic model. Comparative analysis is carried out at the convergence center connecting all receivers to obtain the flight changes of the positioning object in the three-dimensional coordinate system and determine its behavior state. The white light LED positioning method designed on the basis of the above model completely avoids the interference of electromagnetic radiation of electrical equipment...
