Embodiment Construction

[0043] The preferred embodiments of the present invention will be specifically described below in conjunction with the accompanying drawings.

[0044] In the three-dimensional dynamic multimedia stage used in large-scale performances, LED panels that can play videos are installed on the top surface and around the lifting platform. When the lifting platform lifts and forms a static stage shape, each video playback surface displays pictures or videos that match the program, and the lifting platform thus becomes a part of the stage background. Aiming at the dynamic stage used in large-scale performances, the present invention proposes a large-scale performance dynamic stage video editing and display method based on time-space consistency for overall control of LED display display content.

Abstract

The invention relates to a large-scale performance dynamic stage video editing and displaying method based on space-time consistency. The method comprises the following steps of 1, designing a sourcevideo and decomposing the source video into a video frame sequence; allocating a source memory and a target memory; 2, setting a display time interval of a display screen, and executing the followingoperations on each display time point: S1, reading all frame images at the time point into a source memory; S2, obtaining a dynamic stage model corresponding to the time point; S3, determining a display source image corresponding to a stage module display screen, and unfolding the display screen on the plane of the source image to obtain a corresponding segmentation area of each display screen inthe source image; and S4, outputting the segmented regions of all the display screens to a target memory, and then outputting the segmented regions to a display controller. According to the invention,while an accurate stage video background is realized, the complexity of stage management is reduced, and the memory utilization efficiency and the mapping speed are improved.

Description

technical field [0001] The invention relates to a digital video display method of a dynamic stage display screen, in particular to a large-scale performance dynamic stage video editing and display method based on time-space consistency. Background technique [0002] The stage provides space for performances. Whether a theatrical performance can achieve the desired effect, the stage is the foundation. The modern stage, especially the multimedia dynamic stage, creates more space for the development of stage art in a limited stage, and provides directors and choreographers with more changes and choices. [0003] The development of lifting platform is the representative of the development of stage machinery, and lifting platform is widely used in modern stage technology. From the initial small number of lifting platforms to the current use of large-scale lifting platforms, the lifting platform has changed from an auxiliary mechanical equipment of the stage to an important part...
