摘　　要：提出了在具有统一解析式连续背景场基础上实现迭代最近等值线的匹配算法,建立了局部连续背景场的最近点搜索模型,采用BFGS拟牛顿方法实现置信范围内最近等值点精确定位。分别对连续背景场的ICCP匹配算法和离散背景场的ICCP匹配算法进行了两组对比仿真实验。实验结果表明,连续背景场的IC-CP匹配算法在搜索最近等值点方面有了较大改进,匹配精度有了较大提高。A new iterative closest contour point algorithm based on continuous field with the unique analytic expression was presented.The model of searching the closest contour point is firstly built;then the BFGS method of quasi-newton was adopt to locate the closest contour point in confidence region.Finally,two simulation experiments with different conditions have been done to test the effect of the ICCP based on continuous field and the ICCP based on discrete field.From the simulation results,we can see that the new algorithm have been improved in the searching of the closest contour point compared to the normal ICCP and the matching precious of the new ICCP was improved significantly with this reason.
