医用肠道内窥镜图像纹理分析的寻径方法研究

Research of Contour Analysis on Endoscopy Navigation

描述采用纹理分析法进行寻径引导内窥镜头部的方法,该方法首先对内窥镜图像进行边缘提取,然后对边缘线进行骨架提取,最后对边缘线进行分组连接和决策,计算出内窥镜头部偏摆所需的数据。通过实验验证了该方法的可行性及可靠性,该方法的应用可弥补传统方法中因暗区不明显而无法引导内窥镜的不足,提高了内窥镜视觉导航的精度和可靠性。

In this paper, a new method of contour analysis is presented to find path in endoscopy navigation. At first, edge detection is used to endoscope image. Then we do skeleton extraction and connect the edge skeleton to contours by grouping criteria. At last we can get navigation information by analyzing the contours. Experiments show that this algorithm has good precision and stability.
