Embodiment Construction

[0033] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. In the following description, the same reference numerals are given to the same components, and repeated descriptions are omitted. In addition, the drawings are only schematic diagrams, and the ratio of dimensions between components, the shape of components, and the like may be different from the actual ones.

[0034] This embodiment relates to a method for a robot to recognize a positioning mark. The size of the positioning mark increases as the setting height of the positioning mark increases. The positioning mark contains size information and setting height information. Such as figure 1 As shown, the method for the robot to identify the positioning mark involved in this embodiment includes:

[0035] 101. The robot collects the image of the positioning mark, obtains the size information and sets the height information;

[0036] 102. The robot ca...

Abstract

The invention provides a method and system for a robot to identify a positioning identifier. The size of the positioning identifier is increased along with the increase of the set height of the positioning identifier, the positioning identifier comprises the size information and the set height information, and the method comprises the steps that the robot collects an image of the positioning identifier and obtains the size information and the set height information; and the robot calculates the position of the robot based on the size information and the set height information. According to themethod and the system for the robot to identify the positioning identifier provided by the invention, the identification obstacle caused by different set heights of the positioning identifier is overcome.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a method and system for identifying and positioning marks by a robot. Background technique [0002] Mobile robots are currently used in the service industry, including catering, hotels, offices, warehousing and other fields. Commonly used positioning technologies for robots include UWB positioning, laser radar positioning, infrared positioning, visual positioning, inertial navigation, and positioning identification positioning. Among them, the positioning of the positioning mark has relatively strong stability and high accuracy. [0003] Positioning signs usually need to be set at high geographical locations in application scenarios, such as on the ceilings of hotels, restaurants, and offices. Even in the same application scenario, the height of the ceiling from the ground will be different, and the positioning marks are often set at different heights, which will cause obstacles...
