Background giant screen content analysis platform

Abstract

The invention relates to a background giant-screen content analyzing platform. The background giant-screen content analyzing platform comprises a background giant screen, an NAND flash memory, an image-capturing device and a mean value analysis device, wherein the background giant screen is arranged behind a stage and used for providing different kinds of background content for various scenes of performances; the NAND flash memory is connected with the background giant screen and used for outputting the background content which the background giant screen needs to display in each time period,and the NAND flash memory is further used for outputting the background content which the background giant screen needs to display in current time period; the image-capturing device is used for capturing real-time image data of the background giant screen on the stage so as to obtain and output real-time captured images; the mean value analysis device is connected with the image-capturing device and the NAND flash memory and used for receiving the real-time captured images, a background reference image, a left background image and a right background image. Through the background giant-screen content analyzing platform, the background giant-screen content replacement precision can be improved.

Description

technical field [0001] The invention relates to the field of stage control, in particular to a background giant screen content analysis platform. Background technique [0002] The stage screen can divide a screen into multiple video screens for broadcasting. The display screens can be used independently, in combination, or in any combination to play related backgrounds. The stage screen can be displayed in partitions according to performance needs, and can realize the superposition of graphics and text, background The picture is played by a video signal processor or synthesized into the same picture for display, it can play close-ups of characters, it can be used for scrolling and playing of text, or it can be inserted and played, it can move the screen of the video screen horizontally, and it can also be raised and lowered to become text, personalized video screen, brightening, Beautify the stage background and stage ground, meet other requirements and advantages required b...

Problems solved by technology

[0003] In order to solve the technical problem that the background does not match the performance scene in the stage performance, the present invention provides a background giant screen content analysis platform, which can analyze the content of the background giant screen on the stage on-site, so that when the content does not match the current performance scene Provide corresponding prompts; establish an adaptive automatic adjustment mechanism for binarization thresholds, especially refer to neighborhood image thresholds for adjustment, which provides convenience for subsequent image processing; according to the matching results of the captured image and the background image, determine The captured image is offset from the direction of the preset shooting angle, and the capture device is driven and controlled based on the offset direction, so as to realize the automatic homing of the shooting direction of the capture device
