Abstract

The invention discloses an embedding-based high-resolution image expanding platform system comprising a group of camera joints CameraLink, four 16bit SSRAM with the capacity of 4M, an FPGA1 specially performing panorama expansion and Bell interpolation calculation, two 16bit SDRSDRAM with the capacity of 16M, an FPGA2 used for performing all tasks, except for the panorama expansion and Bell interpolation calculation, including display driving and Gigabit Ethernet sending and receiving, a Gigabit Ethernet interface, a display interface used for displaying images of cameras or expanded images in real time, and cameras used for image data acquisition. The SDRSDRAM are used for displaying the Gigabit Ethernet and caching the Gigabit Ethernet transmission. The images are processed in real time in a manner of table tennis, one memory region is used for a fresh segment of image acquisition, another memory region is used for processing the just acquired entire image, acquisition and processing are completed in one image field period, the operations of the memory regions are switched, and the memory regions are used alternately.

Description

technical field [0001] The invention relates to an embedded platform system, in particular to an embedded high-resolution image development platform system. Background technique [0002] In recent years, with the development of digital cameras and even mobile phones from the original resolution of hundreds of thousands of pixels to tens of millions of pixels or even higher, the rapid development of image sensor manufacturing technology requires more and more image and video processing capabilities. come higher. Image processing systems have been widely used in many fields such as industrial production, military affairs, and medicine. The mainstream image processing system is composed of CCD camera, acquisition card and computer, etc. However, these systems often expose disadvantages such as complex structure, high cost, and large volume. With the continuous development of sensing technology, semiconductor technology and embedded systems, a new image processing system——embe...
