Problems solved by technology

The shortcomings of the calculation method of the system are as follows: compared with high-resolution computer images, the number of lifting device arrays is relatively small, and block effects are prone to occur when displaying images with rich content, which reduces the overall demonstration effect of the system

Embodiment Construction

[0031] Aiming at the problem of motion control of the lifting mechanism array, the present invention proposes a technical approach to drive the movement of the lifting mechanism array that conforms to the human visual viewing characteristics, and adopts image edge sharpening and image quality evaluation technology in image processing technology to establish A frame extraction method based on image quality block effect evaluation, which effectively suppresses the block effect phenomenon that occurs during the display process of the lifting mechanism array, and enhances the overall visual impact of the display system.

[0032] Such as figure 1 As shown, the three-dimensional dynamic scene display system of the present invention includes a projector 1 , a lifting mechanism array 2 and an industrial computer 3 . The projector 1 is used to project images and videos to the lifting mechanism array. The elevating mechanism array 2 is composed of multiple elevating mechanisms placed h...

Abstract

The invention provides a lifting mechanism array control method for a three-dimensional dynamic scene display system. The method comprises the steps that downsizing processing is carried out on each frame image in a drive video; edge sharpening processing of the images is carried out on each downsized frame image; for each frame image after being processed through edge sharpening, blocking effect evaluation parameters of the image quality are calculated; for the images after being processed through continuous K frame edge sharpening, the sizes of the blocking effect evaluation parameters are compared, and the image with the smallest blocking effect evaluation parameter is used as the drive image of a lifting mechanism array; K is an integer larger than or equal to five; the motion height of a corresponding lifting mechanism is determined according to the grey value of each pixel in the drive image of the lifting mechanism array, and the lifting mechanism is driven to move to the determined motion height. The method can effectively restrain the blocking effect phenomenon occurring in the display process of the lifting mechanism array, and enhance the overall visual impact effect of the display system.

Description

technical field [0001] The invention relates to a three-dimensional dynamic scene display system, in particular to a control method for its lifting mechanism array. Background technique [0002] With the continuous development of my country's cultural undertakings, many large-scale performing arts activities and exhibition venues have higher and higher requirements for the application of multimedia technology. Traditional display systems only use computer graphics, multimedia projection, and other processing methods to render and display complex scenes. With the continuous improvement of the appreciation level of the broad masses of the people, this kind of traditional display means has gradually been unable to meet the actual appreciation needs. [0003] Chinese patent CN103212210A, the title of the invention "a three-dimensional dynamic mechanical performance system with variable content" introduces a stage performance system with variable content. Rhythmic three-dimensi...
