Abstract

The invention provides a mobile robot and a positioning method thereof. The method includes the following steps that: the voice information of a user is acquired, the direction of the user is positioned according to the voice information; the mobile robot is rotated so as to make an image positioning unit face the direction; an image sequence is acquired, and the feature portion of the user in the image sequence is identified; and according to the position of the feature portion, the position of the user is calibrated, and the distance of the user is positioned. According to the mobile robot and the positioning method thereof of the invention, image acquisition is guided through voice positioning, the feature portion of the user in the image sequence is identified, according to the position of the feature portion, the position of the user is calibrated, and the distance of the user is positioned, and therefore, accurate positioning of the user who is adopted as a sound source can be realized; and the summoning or tracking commands of the user are further identified, and the mobile robot is driven to a position in front of the user after the user is accurately positioned.

Description

technical field [0001] The present application relates to the technical field of human-computer interaction, in particular to a mobile robot and a positioning method thereof. Background technique [0002] Existing positioning methods for robots to locate the speaking user usually use a simple sound source localization method, because sound source localization often has a certain direction error in practical applications, such as an angle error of 5°-10°, and cannot be accurate at the same time. The positioning distance makes it impossible to accurately locate the user. [0003] Furthermore, for service robots, there is a very important scene in human-computer interaction: calling the robot to let the robot know the direction and distance of the speaking user. After the robot obtains the positioning information of the direction and distance, it can turn to the user, move to the user, and interact with the user face to face. Because the existing positioning method is not acc...
