System for collecting and processing 10K*10K ultrahigh resolution images

Abstract

The invention discloses a system for collecting and processing 10K*10K ultrahigh resolution images, belonging to the field of image collection and processing. The system mainly comprises four subsystems, namely an array camera with four camera link output outlets in shunt output, a multichannel image synthetic controller, a low voltage differential signaling (LVDS) image acquisition card, a standard peripheral component interconnect (PCI) bus and a computer system, wherein, the image data source obtained by the array camera is delivered through multiple camera link ports in a shunt mode; the multichannel image data are received and are rearranged to integrate into a 1-path ultrahigh resolution image by the multichannel image synthetic controller, and the 1-path ultrahigh resolution image is transmitted to the LVDS image acquisition card; and the control of the LVDS image acquisition card is finished by the computer. By utilizing the system, the problem of collection, processing, display and storage of the ultrahigh resolution image is solved; the computing capacity of the complete set of the system can be multiplied under the condition of stacking and combination of hardware resources, thus the resolution image up to 20K*20K can be processed.

Description

technical field [0001] The invention relates to a 10K*10K ultra-high resolution image acquisition and processing system, which belongs to the field of image acquisition and processing. Background technique [0002] In the prior art, the resolution of high-definition image signals is 1080P, 1080i (resolution 1920*1080) or 720p (1280*720), but for some special applications, such as satellite reconnaissance, aerial photography, meteorological imaging, remote sensing imaging, medical treatment and other fields . (such as aerospace and remote sensing), 1080P and 1080i are far from meeting the requirements. With the improvement of semiconductor technology, 10K*10K (ie 10240*10240) or even higher resolution pixel sensors have appeared, but because the image data generated by such sensors is large, a single black and white image generated by it, The resolution of each image is up to 100MB. Even if the camera outputs 10 frames per second, the total data flow will reach 1000MB / s. If...

Problems solved by technology

[0003] In the existing image acquisition card with Camera-link, the theoretical maximum input data (Full Camera Link) is 680MB / s, so it is impossible to process the image information of cameras with a resolution equal to 10K*10K or higher Therefore, an ultra-high resolution image acquisition and processing system is required to acquire and process ultra-high resolution images
