Large-screen interaction control method based on human body posture and gesture posture visual recognition

Abstract

The invention discloses a large-screen interaction control method based on human body posture and gesture posture visual recognition, and the method comprises the steps: photographing an operator through a camera, recognizing the human body articulation points of the operator in a camera view field, and recognizing the human body posture and gesture posture of the operator in the camera view field; calculating data such as the distance from eyes of an operator to the ground, the height, the upper arm length, the distance from hands to the ground and the like, and determining the coordinate positions where the eyes of the operator see the large screen through the hands. The large screen controller gives feedback information to the corresponding large-screen picture block according to the coordinate positions on the large screen and the layout information of the large screen based on the human body posture and the gesture posture of the operator. By using the method, an operator can realize the control method of directly interacting with the large screen without any tool, the operation is flexible and convenient, the interactivity is strong, the operator is not limited by a fixed position or a cable, and the operation fatigue is low.

Description

technical field [0001] The present invention relates to the technical field of electronic information, in particular, to a large-screen interactive control method based on visual recognition of human body gestures and gesture gestures. Background technique [0002] With the acceleration of the pace of intelligent construction in the whole field, the large-screen seat system composed of multiple display screens has been widely used in the military, public security, armed police, justice, customs, electric power, disaster prevention and many other fields. The command, control, and dispatch centers in the field, as well as the meeting room clusters of governments, enterprises and institutions, and hotels, provide comprehensive visual solutions for smart security, smart cities, smart transportation, smart inspection, smart education, and smart medical care. [0003] In the existing seat system, there is a fixed operating platform in front of the large screen, which is used for o...

AI Technical Summary

Problems solved by technology

[0004] In the existing seat system, the operator cannot walk freely in front of the fixed operating platform, the interaction with the audience is poor, and the long-term operation of touch, mouse and keyboard is easy to fatigue, which brings a lot of inconvenience to the operator
