Face recognition based control method of exhibition hall robot arm

Abstract

The invention relates to a face recognition based control method of an exhibition hall robot arm. The control method is characterized in that a target face with the shortest physical distance to a lens of shooting equipment for the exhibition hall robot arm is accurately determined from a 360-degree panoramic image with a face feature algorithm, and then a target face is subjected to forward calculation by combining a face attribute algorithm, and attribute information of the target face is obtained; then, control materials such as height, actions and intonation adapted to the attribute information of the target face are generated for the exhibition hall robot arm, and the exhibition hall robot arm is correspondingly controlled according to the control materials. Thus, spatial pose changedisplay of the exhibition hall robot arm can be performed according to the control materials adapted to the attribute information of the target face when the presence of visitors in an exhibition hallarea is accurately identified, power consumption of the exhibition hall robot arm is reduced, and more people are attracted to the exhibition hall area; besides, accuracy of face detection can also be improved.

Description

technical field [0001] The invention relates to the technical field of robot control, in particular to a method for controlling an exhibition hall robot arm based on portrait recognition. Background technique [0002] At present, the robot arm (belonging to a kind of robot) is mainly used in the field of industrial production. It can control an object or tool to change the spatial posture (position and posture), so as to complete the operation requirements of a certain industrial production. In order to reduce the labor cost in the exhibition hall area, more and more exhibition hall areas have begun to introduce the exhibition hall robot arm to replace the manual way to change the spatial posture of the exhibits. [0003] In practice, it has been found that the existing robot arms in the exhibition hall usually control the exhibits in accordance with a fixed program to display changes in spatial poses. Such changes in spatial poses cannot accurately identify whether there ...

Problems solved by technology

[0003] In practice, it has been found that the existing robot arms in the exhibition hall usually control the exhibits in accordance with a fixed program to display changes in spatial poses. Such changes in spatial poses cannot accurately identify whether there are visitors in the exhibition hall area. , so even if there are no visitors in the exhibition hall area, the exhibits are still controlled according to the fixed program to display the changes in the spatial pose, which will increase the power consumption of the robot arm in the exhibition hall; in addition, the changing display of the spatial pose It cannot be flexibly adapted to the attribute information (such as age, height) of visitors, which is not conducive to gathering more popularity for the exhibition hall area
