Abstract

The invention discloses a device for indoor three-dimensional space positioning based on rotary light patterns. The device comprises a periodical flashing light source and a uniform rotation special-shaped fan blade, wherein the plane of the fan blade is parallel with ground; a connecting line between the center of the light source and the center of the fan blade is vertical to the ground; a plurality of devices are arranged on the plane which is parallel with the ground, and the fan blade rotary cycles and light source flashing cycles of the devices are different. The invention also provides a method for the indoor three-dimensional space positioning based on the device. The method comprises the following steps of detecting the change rule of different light patterns by a photosensitive sensor, so as to judge an included angle between a to-be-positioned target and the rotation axis vertical line of the fan blade, and a direction included angle between the to-be-positioned target and the centerline of each fan blade; then, determining the position of the to-be-positioned target by the position of the light source. The device has the advantages that the positioning accuracy is high, the positioning result is stable, the layout cost is low, the hardware requirement of target positioning is low, the number of simultaneously positioned targets is more, the expanding of positioning range is easy, and the like.

Description

technical field [0001] The invention belongs to the field of optoelectronic information technology, and more specifically relates to an indoor three-dimensional space positioning method and device based on rotating light patterns. Background technique [0002] When it comes to positioning and navigation, the most popular technology now is the GPS satellite positioning system. China has also launched its own satellite positioning system, the Beidou Satellite Positioning System. However, satellite positioning can only be used in outdoor environments. Once indoors, satellite positioning cannot be used because the satellite signal attenuates too fast. [0003] Indoor 3D positioning usually has high requirements for positioning accuracy. The existing indoor 3D positioning methods are mainly based on image recognition methods, but this method not only requires high computational complexity and corresponding energy consumption, but also needs to collect a large number of pictures ...
