【摘要】 介绍了医用电子内窥镜畸变实时校正系统的原理与设计实现。在硬件设计中采用视频编码器和视频解码器分别实现对输入模拟信号的解码和输出数字信号的编码,并以SRAM作为输入畸变图像和输出校正图像的存储器。系统的控制中心选用可编程逻辑器件FPGA,以实现对硬件系统功能的灵活修改和扩充。更多还原

【Abstract】 This paper introduces the theory and design of real-time distortion correction system of medical elec-tronic endoscope (MEE). In hardware design, video decoder is utilized to decode input analog signals and videoencoder to encode output digital signals. SRAM is used as memorizers of aberrant input images and calibratedoutput images. Field programmable gate arrays (FPGA) is selected as the control center of the system to imple-ment flexible modification and expansion of system function.更多还原
