AI Technical Summary

Problems solved by technology

Using vision, visual slam positioning, laser slam positioning and other methods for positioning, the amount of data processing is large, the cost of equipment is high, and the real-time performance is not enough.
However, using ultrasonic and aircraft reckoning to locate, because it is often interfered by other electromagnetic frequencies, the positioning accuracy is poor.
Light reflection and UWB, Bluetooth and other space beacon positioning have problems such as complex construction and affecting aesthetics

Abstract

The invention relates to an unmanned system space positioning method based on an LED light source. A positioning device involved in the method comprises LED light sources with identity information, anoptical detection component, a data processing board and a software algorithm. The LED light sources distributed in the motion space of an unmanned system emit optical signals with identity information, the data processing board drives optical detection components on the unmanned system to collect the spatial position and identity information of each LED light source under the control of a software algorithm, and the software algorithm analyzes the self-positioning of the unmanned system from the information. The indoor and outdoor space positioning method is provided for the unmanned systemby utilizing the LED light sources with the identity information, and the method can independently become a space positioning mode of the unmanned system, and can also become a calibration means for positioning modes such as satellite positioning, visual positioning, laser slam positioning, ultrasonic navigation positioning and aircraft calculation positioning.

Description

technical field [0001] The invention relates to a space positioning method for an unmanned system, in particular to an indoor and outdoor space positioning method for an unmanned system based on an LED light source. Background technique [0002] With the development of artificial intelligence technology, intelligent unmanned systems are becoming more and more popular in daily work and life. Accurate positioning is a prerequisite for intelligent unmanned systems to work normally or provide various services. At present, the relatively mature positioning methods mainly include satellite navigation and its ground augmentation station, visual positioning, visual slam positioning, laser slam positioning, light reflection positioning, ultrasonic navigation positioning, aircraft dead reckoning positioning, space beacon positioning, etc. [0003] Under outdoor conditions, using satellite navigation and ground augmentation station positioning signals for positioning is the main way f...
