Embodiment Construction
[0039] The preferred embodiments of the present invention will be specifically described below in conjunction with the accompanying drawings.
[0040] 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 parallel accelerated display method for large-scale performance dynamic stage video that coordinates and controls the display content of LED display screens and uses parallel processing for acceleration.

The invention relates to a large-scale performance dynamic stage video parallel acceleration display method. The method comprises the following steps of 1, designing a source video; 2, starting a producer thread for each display time point in parallel according to a time sequence, and executing the following operations: S1, allocating a source memory and a target memory; S2, obtaining a dynamic stage model corresponding to the time point; S3, unfolding the display screen on a corresponding source image plane, and obtaining a segmentation area according to the corresponding relation between theunfolded geometrical shape and the source image; S4, outputting all display screen segmentation areas to a target memory, and outputting the display screen segmentation areas to a stage screen control video file; and 3, sequentially outputting the stage screen control video files containing all time points to a display controller. According to the invention, while the accurate stage modeling video background is realized, the hardware complexity of dynamic stage management is reduced, and the memory utilization efficiency and the data processing 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 parallel acceleration display method of a dynamic stage video of a large-scale performance. 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 of the stag...
