Implementation Of Super Wide-Angle Image Processing Algorithm By DSP

In modern opto-electronics detection field, the real-time image detection technique is very important, it is widely used in many practical image processing systems. Such as TV control and guide system, electronic endoscope in iatrical, monitor system in supermarket and so on. However in most of the applications, image distortion will be brought in due to the using of wide-angle lens in the image processing system, especially in systems using 180o wide-angel short focus lens. While the using of wide-angle lens achieves a wide imaging range, it also leads to serious image distortion which makes the imaging identification of objects very hard. So image processing systems must use digital imaging technic to revert the distortion image. This article use an appropriate arithmetic base on the characteristic of the wide-angel lens to revert the distortion image , and achive the revert image by the image processing system using DSP as kernel. The system also achieve the communication between DSP and PCI to transfer the image data. The key point of the system contains:(1)hardware design base on the dsp;(2)Communication between DSP and PCI to transfer the image data;(3)Image distortion revert arithmetic model of the wide-angel lens;(4)Optimizing the image distortion revert arithmetic;(5)Bootloader design of the system The major problem of the digital imaging processing technology is that the real-time processing of the image data requires very high operation speed. By utilizing most of DSP's merits, the image processing system introduced in this article implements completely hardware arithmetic which greatly increased the efficiency of the image processing course. Through the PCI interface, the processed image will be transfered to the computer to be displayed simultaneity or be disposed later..
