Abstract

In order to deal with the complicated field environmental conditions that real-time video image process systems have to confront

a general-purpose real-time video image process system is designed

which is extendable and can be applied to multiple field environmental conditions simultaneously. Image process systems based on FPGA+DSP architecture are widely used in the field of image process

because the DSP processor is of high calculating performance and the FPGA is of high real-time performance

while the Compact-PCI bus is extendable because its interface with the computer is already standardized. Combining both advantages

a new general-purpose video image process system is designed based on Compact-PCI bus and FPGA+DSP architecture. Hardware experiments show that

this system can be equal to capturing and processing video images of 320256~1 0241 024 pixels

8~14 bits and maximum frequency of 100 Hz real-timely. Besides

it can also realize real-time control by means of the Compact-PCI bus

of which the result is pretty good. It indicates that this system is capable of dealing with complicated environment

such as infrared and visible scenes. It is real-time and effective. It provides a new possible solution to video image capture and process.
