AI Technical Summary

Benefits of technology

The invented technology allows for accurate location correction based solely upon reflection-sided stickers attached to an object being marked or displayed during navigation. This helps improve accuracy over longer distances without relying heavily on external sensors like GNSS signals.

Problems solved by technology

The technical problem addressed in this patented text relating to robotic systems used at present time involves accurately navigated or guided movements caused by environmental factors like uneven surfaces that can change their shape overtime due to wear and tear from use. This results in errors when determining how well these mobile devices move within an area without being able to navigate them correctly through complex environments with many different types of things. Additionally, current methods require expensive sensors and equipment to track the location of the device's motion, making up one significant portion of costs associated with producing and maintaining robots themselves.

Abstract

The invention provides an auxiliary positioning system for reflective stickers. The auxiliary positioning system comprises a plurality of reflective stickers and a mobile platform. The reflective sticker is arranged in a navigation space. The mobile platform comprises a map establishing module, a positioning module, a laser scanning analysis module, a coordinate processing module, a judgment and comparison module and a correction module. The map establishing module is used for establishing a full-area map corresponding to the navigation space. The positioning module is used for positioning a positioning coordinate. The laser scanning analysis module is used for scanning the navigation space and obtaining a scanning azimuth distance coordinate of the reflective sticker relative to the mobile platform. The coordinate processing module forms a positioning azimuth distance coordinate according to a sticker point coordinate and the positioning coordinate. The judgment and comparison modulecompares the scanning azimuth distance coordinate with the positioning azimuth distance coordinate, and corrects the positioning coordinate through the correction module.
