【摘要】 利用现场可编程门阵列(FPGA)作为主控芯片,研制了医用电子内窥镜的成像系统。主要包括4个部分:光学成像系统,CCD驱动、图像采集、编码电路(驱动CCD、控制图像采集与编码),彩色图像畸变实时校正系统(用于实时在线校正内窥镜光学系统的畸变),视频驱动亮度控制系统(调节光源的发光亮度)。最终研制成具有高分辨率(702×576)彩色图像畸变实时校正功能的医用电子内窥镜系统。更多还原

【Abstract】 Medical electronic endoscope(MEE) is a widely used medical instrument.Using the field programmable gate array(FPGA),four parts of work are accomplished: optical imaging system;driving of the charge coupled device(CCD),the functions of image data acquisition and display;a real-time correction system of image distortion via hardware is designed based on the dot-array plate arithmetic;automatic brightness control of electronic endoscope based on video-servo control method.Finally,a medical electronic endoscope system with a real-time correction system of high-resolution(702×576) color image distortion is developed.更多还原
