目前建筑施工测绘存在效率低下的问题。通过对目标图像进行灰度变换，以及包括图像校正、对比度展宽、灰度窗切片等图像处理方法对摄像机采集到的建筑外形目标图像边缘进行提取，从而获取目标结构的外形尺寸信息这一方法，可以有效解决该问题并且提升建筑结构检验的工作效率。MATLAB仿真实验结果表明这一方法取得了令人较为满意的结果。

Nowadays low efficiency is a problem to be solved in construction surveying and mapping. Method like by pro?ceeding gray level transformation for target image, and then by adopting image processing methods including image rectifi?cation, contrast broadening, gray level window section and etc. to extract the image border of the target image of the archi?tectural appearance which has been caught by video camera to obtain the information of target architecture's boundary di?mension is very efficient in solving such a problem and thus does a good job in promoting the work efficiency in the test of the architectural structure. The MATLAB simulation experiment results show that this method has obtained more satisfac?tory results.
