摘要
研究了基于ICT切片图形三维重构的轮廓边界配准技术。提出了基于边界象素链的轮廓边界的配准方法,首先进行轮廓层次编码,然后对图像进行有向距离变换,并计算配准度构造配准关系表,最后由配准关系表获取相配准的轮廓边界。实验表明,该方法具有很高的准确性和有效性。
The edge-matching technique of 3D reconstruction based on industrial computerized tomography （ICT） slicing images was researched. In this paper an edge-matching method based on edge-pixels-chain was proposed. Firstly, every edge in a slice is coded on each layer, and then distance transforming is made to every slice. Secondly, matching degree is calculated in every two edges of every two slices, and then matching relation tables are created based on calculated matching degree. Finally, matching edge is picked out according to the matching relation table. The accuracy and effectiveness of the above algorithm is shown by experimental results.
