Follow-up curtain, control method and device, and storage medium

Abstract

The present application discloses a follow-up curtain, a control method and device and a storage medium. The follow-up curtain comprises a curtain body, a control component, at least one detector, a processor, and a driving motor; the control component comprises a processor, a detector and a driving motor, the at least one detector is used for sending a detection result to the processor, and the detection result indicates whether a captured object is in the edge region of the curtain; the processor is used for generating a driving signal based on the detection result, and the driving signal isused for changing the current running state of the driving motor; and the driving motor is used for changing the current motion state of the curtain based on the driving signal so that the captured object is located within an effective coverage area of the curtain. In the embodiment of the present application, whether the captured object is located in the edge region is detected and captured through the detector, a driving signal is generated by the processor based on the detection result of the detector so as to trigger the driving motor to operate and drive the curtain to move, thereby preventing the captured object from moving out of the effective area covered by the curtain, realizing follow-up movement of the curtain and ensuring smooth conduction of hybrid display imaging.

Description

[0001] technology neighborhood [0002] The present application generally relates to the field of augmented reality technology, and specifically relates to a following screen, a control method, a device, and a storage medium. Background technique [0003] In the mixed display live broadcast system, it is usually necessary to obtain the video information of the participants, process the video information, and combine it with the virtual scene to form the required mixed display result. For example, multi-participating teaching requires real-time collection of the scenes where teachers and students are located, and finally aggregates them to the server to generate virtual display scenes to achieve multi-participating mixed display teaching. [0004] When acquiring the video information of the participants, it is usually necessary to use a fixed green screen or blue screen as the background. After the video is acquired, it is convenient for keying processing and synthesizing a vir...
