摘要
利用目前方法对立体图像任意剖面轮廓线进行提取时,没有对图像进行预处理,存在轮廓线提取耗时长、提取完整度差和与实际轮廓线匹配误差大的问题。为此提出基于光切法的立体图像任意剖面轮廓线提取方法,该方法基于光切法对立体图像进行预处理,将图像分割成光带和背景图像,依据预处理后的图像及光带对初始立体图像任意剖面轮廓线进行处理,根据通过任意方向和任意位置的剖切,构建出三维形体;针对剖面与断层轮廓线之间的交点,采用凸包压入法将包络在初始轮廓线中的点添加到轮廓线内,从中获取完整的剖面轮廓线,实现对剖面轮廓线的提取。实验结果表明,通过对该方法进行耗时测试、完整度测试和与实际轮廓线匹配对比测试,验证了该方法的精准度高、有效性强。
During the extraction of arbitrary section contour of the stereo image,the lack of preprocessing image results in long time-consuming,poor integrity,and large matching error.In this paper,an arbitrary section contour extraction method of stereo image based on the light cutting method is designed.According to the light cutting method,the stereo image was preprocessed to segment the image(light band and background image).According to the preprocessed image and light band,any section contour of the initial stereo image was processed.The three-dimensional shape was constructed by cutting in any direction and at any position.According to the intersection between the section and the fault contour,the convex hull pressing method was applied to add the points enveloped in the initial contour to the contour,obtaining the complete section contour.Eventually,the extraction of the section contour was completed.The results show that this method has high accuracy and excellent effectiveness.
