Abstract

The embodiment of the invention relates to a method and a device applied to indoor location of a mobile robot. The method comprises the following steps: estimating the current location of the mobile robot according to the indoor location technique of the mobile robot; accessing a reference object database and selecting a real location and relevant reference images from the database; navigating the mobile robot to the selected real location; shooting images by using a camera matched with the mobile robot to obtain shot images; comparing reference object images included in the shot images with reference object images included in the selected reference images; and determining location errors generated by the indoor location technique of the mobile robot according to comparison results. Through the method and the device applied to indoor location of the mobile robot according to the embodiment of the invention, the indoor location of the mobile robot can be improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of indoor positioning of mobile robots, and more specifically, to error determination and error correction of indoor positioning of mobile robots. Background technique [0002] With the rapid development and maturity of mobile robot technology, the application of mobile robots in indoor environments such as homes and public places is becoming more and more extensive. Various services and applications based on mobile robots require mobile robots to be able to know their own positioning information in real time, including their own position and heading, and then they can accurately reach the destination according to the planned path to complete the specified tasks. Therefore, indoor localization is one of the key technologies in the field of mobile robotics. [0003] Various technologies have emerged for indoor positioning, such as ultra-wideband technology, wireless local area (WLAN)-ba...
