A foreign object detection algorithm is proposed,which is adapted to the inspection robot working outdoor in the smart substation. First,the template images are manufactured for electric inspection equipments. SIFT method is utilized to match with the template images for detecting the pending device region from the real?time image captured by the robot,and then a normalized method is produced to both device ROI images to reduce the light influence. After the two binary images per?formed,an improved Hu moment algorithm is utilized to compare with the difference of the same device. If foreign object is sus?pended on the target device,the difference region will be marked in real time by the proposed method. Experimental results show that the proposed method is both effective and accurate.
