| description | In the field of intelligent operation and maintenance of subway trains, the detection of abnormal appearance of trains is an indispensable important link. From traditional manual inspections to 2D imaging image recognition methods of line array cameras, there are certain defects, which are not enough to achieve fast and accurate intelligent inspections. The image recognition method based on 2D imaging can solve the problems of slow manual inspection and missed inspection caused by fatigue. However, the abnormal problems that occur in the third dimension perpendicular to the imaging plane have not been well resolved. A bolt looseness detection method based on 2D/3D imaging was proposed, which avoided the impact of excessive changes in image pixel values caused by light, water stains, gray layers, etc. on the detection results in 2D imaging, and can be applied to abnormal detection of subway trains very well. |
