Positioning method based on LED light fixture positioning and directional wheel combination positioning

Abstract

The invention discloses a positioning method based on LED light fixture positioning and directional wheel combination positioning. Wheels of a navigation vehicle are transformed into directional wheels; and a displacement monitoring positioning device is installed at the navigation vehicle. When the navigation vehicle is in an LED illumination area, the displacement monitoring positioning device collects information and transmits the information to an optical positioning system for processing to obtain coordinate information of the navigation vehicle; when the navigation vehicle is not in theLED illumination area, the displacement monitoring and positioning device collects the information of navigation vehicle driving and transmits the information to a displacement monitoring system, calculation is performed based on a odometer method and a displacement and polar coordinate algorithm by using the navigation vehicle positioning information as a reference to obtain coordinate information of the navigation vehicle; and when a user enters the LED illumination area again, positional correction is performed by using the collected optical signal information, so that the cumulative errorcalculated by the displacement monitoring positioning device can be corrected. On the basis of combined positioning of the e optical positioning system and the displacement monitoring system, the high-precision positioning of the indoor blind zone is realized.

Description

technical field [0001] The invention relates to a positioning method, in particular to a combined positioning method based on LED lamp light positioning and directional wheels. Background technique [0002] With the development of society and the continuous improvement of positioning technology, as we all know, GPS is very powerful, and its positioning accuracy can reach the meter level, and it is used by all walks of life. However, it also has an obvious defect, that is, it cannot locate when there is no GPS signal indoors. Various positioning technologies appear indoors, mainly including RFID, Bluetooth, ZIGBEE, WIFI, UWB, etc., but due to problems such as positioning accuracy, hardware layout and cost, they have not been well applied. In large shopping malls, airports or other areas, people tend to get lost indoors, and there is an urgent need for products with positioning and navigation. [0003] Using indoor LED positioning lamps, compile the information that needs to...

Problems solved by technology

[0004] In order to solve the defect that there are no LED positioning lamps in some indoor areas, resulting in blind spots for light positioning, the present invention provides a method based on the combined positioning of LED lamp light positioning and directional wheels. On the basis of using the indoor LED positioning lamp light positioning system , refit the wheels of the navigation vehicle into directional wheels, and install a displacement monitoring and positioning device on the navigation vehicle to realize continuous positioning and navigation in areas without LED lights, and at the same time reduce the laying of LED positioning lamps to achieve high-precision indoor positioning without blind spots
