针对眼角膜内皮细胞分析仪手动定位跟踪眼球, 提出了一种基于嵌入式自动定位跟踪系统的设计方法, 采用图像处理与红外测距相结合的方法, 对目标物体进行了实时定位跟踪实验, 实现了对目标物体的自动定位跟踪, x、y轴定位误差不超过7个像素点, z轴定位误差不超过3mm。经临床证实该方法具有高可靠性、实时性和可实施性。

In this paper, proposed is an embedded automatic locating and tracking system based on eye corneal endothelial cell analyzer manually locating and tracking eyeball. It is adopted the combining method of image processing and infrared distance measurement, then the real-time locating and tracking experiment was performed on the target object and the automatic locating and tracking function was realized on target objects. The locating errors of X and Y axis are not more than seven pixels and the positioning error of Z axis is not more than 3mm. The method is verified to own high reliability, real-time and practicability according to clinical tests.
