Abstract

The invention discloses a two-dimensional-code recognition method and a robot visual-navigation self-positioning method based thereon. A manner of apex angle positioning squares of an encoding patternof a two-dimensional code includes respectively arranging a positioning square at each of three of four apex angles of the encoding pattern of the two-dimensional code, and forming a middle nine-square encoding region by 3*3 numerical squares. According to the recognition method, horizontal and vertical division of nine regions are carried out on nine-square encoding regions to obtain corresponding binary numbers by decoding, view angle directions and a binary character string of each numerical square are determined according to different position combinations of positioning squares, data information of two-dimensional codes is obtained, two-dimensional-code information can be accurately extracted, and recognition is carried out according to the different view angle directions. Accordingto the robot visual-navigation self-positioning method, different intersections are marked through a nine-square encoding scheme, robot autonomous-positioning is realized according to encoding resultsof visual recognition, thus autonomous walking according to a set plan path is realized, costs are low, and the self-positioning method is also simple and reliable.

Description

Technical field [0001] The invention relates to a two-dimensional code recognition method and a robot vision navigation self-positioning method based on the two-dimensional code recognition method, belonging to the field of artificial intelligence technology. Background technique [0002] At present, inspection robots based on visual navigation are an important research topic in the field of artificial intelligence. The future commercial market is extremely widely used. For example, museum tour guide robots explain historical relics to tourists, and food delivery robots order and deliver meals to customers along the trajectory. For meals, the hotel service robot self-plans the path for customers to check luggage and guide customers to the guest room. While providing these services, the robot needs to know where it is currently and which direction to go next to reach the destination, etc. Then, the autonomous positioning of the robot has become an indispensable part of the robot'...
