The invention relates to an operation line corridor environmental factor change monitoring method, which comprises the following steps: identifying an edge curve of a building in an image by using Canny segmentation, and then performing standard Hough transformation on the edge curve obtained by Canny segmentation to identify a rectangular area, so that points and operand required to be calculated by the Hough transformation can be reduced, in other words, calculation of Hough transformation is only carried out on the detected edge points; and finally, finishing the positioning of the suspected house target through an improved ROI algorithm. According to the invention, the working efficiency of power transmission and transformation project operation line environment factor identification work is improved, and the edge information of buildings such as houses and plants can be accurately identified. 本发明涉及一种运行线路走廊环境因子变化监控方法，利用Canny分割识别图像中建筑物的边缘曲线，然后在Canny分割得到的边缘曲线上进行标准Hough变换来识别矩形区域，这样能减少Hough变换需要计算的点和运算量，也就是只在检
