摘要
为客观、定量地评价医用硬性内窥镜的光学性能,根据国内外相关检测检验标准,设计由高清CMOS图像传感器、精密机械装置、测试标靶组成的检测装备,编写Matlab程序对采集到的标靶图像进行自动分析和处理,实现基于机器视觉的检测医用硬性内窥镜角度、分辨率、几何畸变、色彩还原能力、光效、照明等光学参数的设备、方法和技术。对德国蛇牌PE 610 A型腹腔镜的测试结果表明:与厂家标称值和国家食品药品监督管理局测试结果符合良好,误差小于4%,其误差主要来源于图像传感器的无照电流。
To evaluate the optical quality of medical rigid endoscope objectively and quantitatively, the authors designed the equipment consisting of HD CMOS image sensor, precision machinery, and test targets according to all the important and related inspection standards, and write Matlab program to make it analyze and process images automatically. Based on machine vision, the research realizes the instrument,method and technology to evaluate parameters of angle, resolution, distortion, color restoration ability, brightness uniformity, illumination of medical rigid endoscopy. The test results of a laparoscope of the snake brand PE 610 A are well matched with the nominal value of manufacturer and those of SFDA, the errors are less than 4% and mainly come from the dark current of COMS image sensor.
