Embodiment Construction

[0016] The present invention is described in more detail below in conjunction with accompanying drawing example:

[0017] An embedded-based image processing system of this resolution, which consists of: Camera Link camera interface, SSRAM with a capacity of 4M×16 bits, FPGA1EP3C80F780I7, SDR SDRAM, EP3C80F780I7, and display driver.

[0018] It is characterized by real-time processing of images, using ping-pong operation, one memory area is used for the acquisition of a new image, and the other memory area is used for the processing of the entire image just collected, which is collected within one image field cycle and processing must be completed, and then switch the memory region it works on, alternately.

[0019] Its characteristic is that the SSRAM selected by the system is CY7C1472BV25 of CYPRESS company, the working voltage is 2.5V, the organizational structure is 4M×18bit, it is a synchronous SRAM with pipeline, the nominal working frequency is 200MHz, it can operate in ...

Abstract

The invention discloses a resolution image processing system based on embedded type. The resolution image processing system based on embedded type comprises a camera interface of Camera Link, SSRAM with capacity of 4M*16 bit, RPGA1EP3C80F780I7, SDR SDRAM, EP3C80F780I7 and a display drive; two SDR SDRAMs of 16M*16 bit are used for displaying the cache transmitted by the kilomega network; FPGA2 used for performing the tasks except for panorama unrolling and bell interpolation operation, including the drive for display, receiving and sending of the gigabit Ethernet; a gigabit Ethernet interface, a display interface used for displaying the image of the camera at real time or the unfolded image; the camera is used for collecting the image data. The ping-pong operation is adopted for processing the image at real time, an internal storage is used for collecting the new image while the other internal storage is used for processing the whole image collected just now, the collecting and processing operation is finished in one image field period, and the working internal storage is switched and used alternately.

Description

technical field [0001] The invention relates to an image processing system, in particular to a system for developing high-resolution panoramic images applied under an embedded platform. 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 ...
