The invention relates to the field of space positioning, in particular to an optical-inertial fusion space positioning method and a positioning system. The method specifically includes: arranging infrared feature points in the space to be positioned, and encoding based on the layout method; calibrating the infrared feature points, obtaining accurate three-dimensional coordinates of the infrared feature points, and storing them in the computing unit; Infrared camera, based on the image information of infrared feature points captured by the infrared camera worn by the target and the sensor data integrated by the infrared camera itself, the target is positioned through the optical and inertial fusion algorithm. The positioning system includes infrared feature points, an infrared camera and a computing unit. The invention adopts the positioning method of optical and inertial fusion, which not only avoids the defects of poor anti-blocking performance of optical positioning and the inability to accurately locate for a long time by inertial positioning, but also reduces the system cost by reducing the number of cameras deployed in the system.
Description
technical field [0001] The invention relates to the field of space positioning, in particular to an optical-inertial fusion space positioning method and a positioning system. Background technique [0002] With the rapid development of LBS, VR and other fields, spatial positioning technology has also attracted much attention and developed rapidly in recent years. The current mainstream indoor space positioning technology includes laser positioning technology, infrared optical positioning and so on. [0003] The laser positioning technology scans the positioning space through the laser transmitter firing several times per second to realize the position tracking of the photosensitive sensor. Laser positioning technology relies on a motor to drive the laser line to rotate and scan the positioning space, so its frame rate is limited by the number of motor revolutions. The same positioning space needs to arrange multiple laser transmitters so that the laser line covers the entir...
