Problems solved by technology

[0002] In indoor scenes such as computer rooms, office areas, and warehouses, mobile robots need to obtain the current position of the robot in real time and perform path planning when moving and inspecting. Currently, commonly used technologies include laser radar, RFID, UWB, Bluetooth, and image vision. Each method has its own advantages and disadvantages in terms of deployment, price, and accuracy, but there is still a certain contradiction between operational accuracy and investment cost

Embodiment Construction

[0027] In order to clearly illustrate the technical characteristics of the present solution, the present application will be described in detail below through specific implementation modes and in conjunction with the accompanying drawings.

[0028] In the first embodiment, as in figure 1 As shown, proceed as follows:

[0029] S101. Positioning of the mobile robot: enter the specified position through the indicator symbol, adjust the orientation of the mobile robot according to the indicator line, and use the specified point for precise positioning;

[0030] S102. Obtain the moving path: obtain the overall layout through the path calibration system, and then optimize the optimal path through the path optimization system. During the process of optimizing the optimal path, for each steering angle and moving distance, assign values ​​according to the set weights , the path with the lowest weight is the optimal path;

[0031] S103. The mobile robot moves according to the optimal ...

Abstract

The invention discloses a visual indoor positioning method and system based on top indication symbols, and the method comprises the following steps: providing an indication assembly with a plurality of indication symbols at the top, and enabling a mobile robot to be located below the indication assembly; the mobile robot obtains an indication symbol, obtains position information and current orientation angle information of the mobile robot according to the indication symbol, then automatically plans a path, adjusts the advancing direction and then walks; wherein the indication symbol comprisesat least a first indication mark and a second indication mark, and the first indication mark and / or the second indication mark are / is further provided with an indication line used for adjusting the advancing direction of the mobile robot and an indication point used for adjusting the position of the intelligent mobile robot. The first indication mark and the second indication mark which are arranged in a matched mode are arranged, and direction positioning of the mobile robot can be achieved through arrangement of the opposite directions of the two marks.

Description

technical field [0001] The present application relates to a visual indoor positioning method and system based on top indicator symbols. Background technique [0002] In indoor scenes such as computer rooms, office areas, and warehouses, mobile robots need to obtain the current position of the robot in real time and perform path planning when moving and inspecting. Currently, commonly used technologies include laser radar, RFID, UWB, Bluetooth, and image vision. Various methods have their own advantages and disadvantages in terms of deployment, price, and accuracy, but there is still a certain contradiction between operational accuracy and investment cost. Contents of the invention [0003] In order to solve the above problems, the present application discloses a visual indoor positioning method based on top indicator symbols on the one hand, including the following steps: providing an indicator component with several indicator symbols on the top, placing the mobile robot u...
