A kind of image procossing accelerating system based on FPGA

Technical field

The utility model relates to image processing system, specifically a kind of image procossing accelerating system based on FPGA.

Background technology

Image procossing is a part of Signal and Information Processing subject, is also an of paramount importance part in field of video monitoring.Along with the develop rapidly of technology, no matter image procossing is in algorithm, system configuration, or in application and popularity all achieves considerable progress, but be applied to industrial intelligent application aspect and be also in the starting stage, still have a large amount of technology to need constantly research and development and capture.The image of smart camera accelerates process and also belongs to blank in the world.Along with intelligent sensor concept is progressively ripe, the demand of smart camera end acceleration process graphical analysis can be more and more higher.Powerful disposal ability and lower product price are that can intelligent sensor one of the factor of large-scale promotion.

Image processing system traditional at present has three kinds, utilizes analogue camera to realize image procossing; IPC and industrial computer is utilized to realize image procossing; Digital camera is utilized to realize image procossing.

There is certain defect in this several image procossing mode, concrete manifestation is as follows:

1), when utilizing analogue camera to realize image procossing, because the image of analogue camera shooting is inherently unclear, then through analog-to-digital conversion, picture quality obviously reduces, and affects image recognition.

2) when utilizing IPC and industrial computer to realize image procossing, along with image size is increasing, network delay also can be very large; When carrying out multiple recognizer process, processing speed can be slack-off;

3) when utilizing digital camera to realize image procossing, at process some large-scale algorithms or when processing multiple recognizer, disposal ability is nowhere near.

4) image procossing solution traditional more than all adopts serial process mode, and therefore when processing multiple image, processing speed is slow, and time delay is longer.

Summary of the invention

The technical problems to be solved in the utility model is: overcome deficiency of the prior art, a kind of image procossing accelerating system based on FPGA is provided, utilize FPGA to carry out data localized, there is high real-time, the high demand of industrial circle to picture quality can be met.
