Abstract
Disclosed are a method for locating a warehousing robot, a method for constructing a map, a robot and a storage medium. In a specific embodiment, a semantic map of a warehouse environment is constructed in advance, and the semantic map comprises a plurality of objects existing in the warehouse environment and semantic information of the objects. In the localization process, a warehousing robot uses its own image sensor to acquire an image or video data of a surrounding environment (), identifies target objects in the image or video data and semantic information of the target objects () to obtain the relative position relationship between each target object and the warehousing robot (), and then determines the location of the warehousing robot in the semantic map based on the relative position relationship and the semantic information of each target object (). The method for constructing a map is based on visual semantic localization. Because the method directly detects specific targets, the detection speed is fast, semantic information is rich, and the method is not easily influenced by other interference factors. The method gets rid of the dependence on signs in the warehouse environment and has high localization flexibility.
