Description: 在图像测量等工程应用中,需要获得目标的高精度图像边缘信息.本文首先介绍了一种基于Facet模型的亚像素边缘检测算法,该方法具有抗噪能力强,定位精度高等优点,但是计算复杂度太高.针对此缺点,本文研究了一种改进算法,将其与Mallat的小波变换模极大算法有效的结合,不仅处理速度提高了10倍左右,而且所提取的边缘效果也有所改善.实验结果表明,本文的方法不仅能获得高精度的边缘信息,抗噪能力强,而且处理速度快。-Need to obtain the target image measurement and other engineering applications, high-precision image edge information. This paper first introduces a sub-pixel edge detection algorithm based on the Facet model, the noise immunity, high precision positioning, but the computational complexity too high. this shortcoming, this paper, an improved algorithm, Mallat wavelet transform modulus maxima algorithm effective combination, not only the processing speed of about 10 times, and extracted the edge effect is also improved. The experimental results show that this method can not only get to the edge of the high-precision, noise immunity, and processing speed.

Description: 曲面拟合法是一种高精度、计算量小、抗噪性能强的方法，当前已被广泛地应用于
各种场景。比如岩石材料的变形测量、电子器件变形的测量、基于掌纹图像相关匹
配的重复定位技术等。曲面拟合法能够成功计算出亚像素位移的前提是整像素搜索阶
段可以正确搜索出模板的整像素匹配点，一旦整像素匹配点搜索出现错误，那么亚像素
测量阶段所得到的位移距离就会失去意义。
使用不同的拟合函数对相关系数矩阵进行曲面拟合，会对结果产生一定的影响，比
较常用的拟合函数有二次函数、三次函数、高斯函数等。(Surface fitting method is a high-precision, computational complexity is small, strong anti-noise performance method, has been widely used in various scenes. For example, deformation measurement of rock materials, deformation measurement of electronic devices, and repetitive location technology based on palmprint image correlation matching. Surface fitting method can successfully calculate the sub-pixel displacement on the premise that the whole pixel search stage can correctly search the template of the whole pixel matching point, once the whole pixel matching point search error, then the sub-pixel measurement phase of the displacement distance will be meaningless.
Using different fitting functions to fit the surface of the correlation coefficient matrix will have a certain impact on the results. The commonly used fitting functions are quadratic function, cubic function, Gaussian function and so on.)
