摘要

提出了一种探针定位测量方法.利用探针上的标记点(可用摄像机定位)建立探针坐标系

运用机器视觉中的立体视觉和坐标系变换的原理

由摄像机坐标系下标记点的坐标得到探针尖端的坐标

实现视线被遮挡的手术部位的视觉定位

摆脱了测量精确度的提高对于探针制造工艺的依赖

显著提高了定位精度(将绝对误差值缩小到1mm)

并进行了实验研究

结果表明:这种方法在实际定位测量中的良好效果

克服了传统探针的准确度由于制作工艺原因无法提高从而成为手术精进的瓶颈的问题

该方法还可应用于外科手术之外的领域

能够扩展到其他探针定位的工业场合.

Abstract

A probe positioning method is proposed

which sets up a probe coordinate system using markers caught by camera and makes out the transformation between probe coordinate system and reference coordinate according coordinate transformation theory in computer vision. Then

the coordinate of the probe tips on operation place out of sight can be worked out. This method can avoid the dependence on techniques in improving operation precision and decrease absolute error to 1 mm. Experiment data and results are also attached to show the excellent efficiency of the method. It solves the bottleneck in improving operation precision because of technical reason. The method can be used not only in operation field

but also in other many industrial occasions.
