| 摘 要： | 为了提高桥梁变形检测的精度,文章提出了一种基于像素点灰度值插值的边缘检测方法。该算法首先对桥梁结构表面灰度图像进行插值运算,然后利用经典边缘检测算子检测结构变形。通过仿真实验证明该方法有效,变形精度满足工程检测要求。

| Abstract: | In order to improve the precision of the bridge deformation detection,this paper puts forward the digital image zoom combined with the classics approach for edge detection to calculate the gray image,then the edge detection approach is designed based on the interpolation of gray of pixels.Which carried on the edge recognition to detect the bridge deformation construction.This approach is proved to be simple,effective,satisfied to the requirements in the project detection by the simulation experiment. |
