High-definition panoramic video image collecting and processing system

Abstract

The invention discloses a high-definition panoramic video image collecting and processing system. The system comprises an imaging module, an image collecting and processing module and a display screen; the imaging module comprises an aspherical mirror, a camera module and an imaging lens, and the image collecting and processing module comprises a camera interface, an SPI-FLASH, an SDRAM, a displayer interface, a programmable logic gate array, a data signal processor, a clock module, an NOR-FLASH, a DDR2-SDRAM and a power module; the imaging module is electrically connected to the image collecting and processing module, and the image collecting and processing module is electrically connected to the display screen. In the high-definition panoramic video image collecting and processing system, real-time high-definition panoramic video image collection with the horizontal angle of 360 degrees and the vertical angle of 80 degrees can be achieved only by a single camera, and a collected annular image can be spread into a normal image convenient to observe by human eyes in real time and displayed.

Description

technical field [0001] The invention relates to the technical field of image acquisition and processing, in particular to a panoramic video image acquisition and processing system. Background technique [0002] Ordinary cameras have a limited field of view and can only capture scenes within a certain fixed-angle space in front of the camera. They cannot take into account all events that occur within the surrounding 360° range, and blind spots are inevitable. Panoramic imaging technology can simultaneously perceive scene information within 360° at any point in time and eliminate visual blind spots, so it has been widely used in military, video surveillance, machine vision and other fields. [0003] Panoramic imaging technology mainly includes: image stitching panoramic imaging technology, fisheye panoramic imaging technology, and catadioptric panoramic imaging technology. Image mosaic panoramic imaging technology needs to take multiple images and do post-processing through i...

Problems solved by technology

[0005] In view of the problem that the image processing speed is difficult to reach the video frame rate in the existing high-resolution catadioptric panoramic imaging processing technology, the present invention provides a high-resolution panoramic video image acquisition and processing system, which can achieve horizontal 360°, vertical 80° high-resolution panoramic video images are collected in real time, and the collected circular images can be expanded into normal images that are easy for human eyes to observe and displayed in real time
