基于FPGA的实时图像数据采集模块设计

Design of Real-Time Image Data Acquisition Module Based on FPGA

论述了基于FPGA的实时图像处理系统数据采集模块的设计方法。在该设计中,先将实时图像数据离散成ITU-656数据格式,然后把图像数据分奇偶场存储到SRAM的高8位和低8位字节中,从而实现帧存储,以方便后续处理。该设计在整个系统中进行了联调,经验证,能正确实现实时图像数据采集。

A real-time data acquisition module for image processing system was designed based on FPGA. In this design, the real-time image was converted into digital data. The odd- and even-field were placed into the upper and lower 8 bits of each byte in SRAM, respectively, to realize frame storage for further processing. The design was tested with the system, and results showed that the module can acquire real-time image data properly.
