Embodiment Construction

[0054] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0055]The present invention at first provides a kind of multi-channel panoramic video splicing method based on texture mapping, comprising the following steps:

[0056] S1: Acquire M channels of video images.

[0057] In a single FPGA ( UltraScale+ TM On the MPSoCs XC ZU7-1FFV), the high-definition panoramic video input by M channels is received by the high-speed serial transceiver of the FPGA, and the serial data is converted into parallel data and synchronous signals. M-channel video signals are processed in a parallel pipeline mode to perform brightness equalization algorithm respectively.

[0058] S2: Perform brightness equalization algorithm processing on M channels of video images respectively.

[0059] The high-definition panoramic vide...

Abstract

The invention discloses a multi-channel panoramic video tiled display method and system based on texture mapping. The method comprises the following steps: acquiring M channels of video images; respectively carrying out brightness equalization algorithm processing on the M paths of video images; performing texture mapping and splicing fusion processing on the M paths of videos processed by the brightness equalization algorithm; fusing frame data for display. The system comprises M paths of video sources, M paths of equalizers, N paths of drivers and N paths of displays, and further comprises an FPGA module. By adopting a single FPGA chip assembly line mode, multi-channel video splicing and fusion are realized through the method disclosed by the invention; according to the method, the multi-chip data interaction delay time is fully shortened, the design complexity is reduced, the problems of poor real-time performance and complex design when multiple paths of camera inputs are spliced into a panoramic image in the prior art are solved, and the method has the characteristics of short time delay and simple design.

Description

technical field [0001] The invention relates to the technical field of image processing and video processing, and specifically discloses a multi-channel panoramic video mosaic display method and system based on texture mapping. Background technique [0002] With the continuous development of science and technology, panoramic video display technology has penetrated into all aspects of people's life and work, such as culture and education, science and technology, security monitoring, etc., all have applications of panoramic video display technology. [0003] At present, multi-channel panoramic splicing display generally uses a combination of multiple processing units to realize the splicing display technology. Multiple processing units need to perform a large amount of data interaction in multiple aspects such as video data acquisition, preprocessing, splicing algorithm parameter calculation, and panoramic output display. , The real-time transmission of a large amount of data ...
