The invention discloses a large-screen interactive control method based on visual recognition of human body posture and gesture posture. The operator is photographed by a camera, the joint points of the human body of the operator in the field of view of the camera are recognized, and the posture of the human body of the operator in the field of view of the camera is recognized and gesture posture, calculate the height of the operator's eyes from the ground, height, upper arm length, height of the hand from the ground, etc., and determine the coordinate position of the operator's eyes on the large screen through the hands according to the data. The large screen controller gives feedback information to the corresponding large screen blocks according to the coordinate position on the large screen and the layout information of the large screen, and according to the human body posture and gesture posture of the operator. Using this method, the operator can realize the control method of directly interacting with the large screen without using any tools, the operation is flexible and convenient, the interaction is strong, the operator is not bound by a fixed position or cables, 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...
