Choke transformer box image real-time screening method based on rail web plug pin image recognition

Abstract

The invention provides a choke transformer box image real-time screening method based on rail web plug pin image recognition. The method comprises the following steps: S1, sending a trigger signal tostart a rail web plug pin camera and a choke transformer box camera to start continuous acquisition after inspection is started; S2, performing target detection on the image acquired by the rail web plug pin camera, and starting the choke transformer box camera to extract the image from the cache if the identification result contains the rail web plug pin; and S3, screening out an image containingthe choke transformer box, and storing the image. According to the method, a detection result of a rail web plug pin is used as a trigger signal of a choke transformer box acquisition camera storageimage; and the classifier is used for judging whether the to-be-detected image contains the rail web plug pin or not, so that the images without the choke transformer box can be reduced on the premisethat the choke transformer box is not missed, the detection efficiency of the choke transformer box can be improved, and the real-time performance of the image screening process is enhanced.

Description

technical field [0001] The invention relates to the field of image recognition, in particular to a real-time screening method for images of choke transformer boxes based on image recognition of rail plug nails. Background technique [0002] The choke transformer is installed at the rail insulation of the double-rail track circuit in the electrification section, and plays an insulating role in the signal current in the track circuit. It can not only separate the signal current in adjacent track circuits, but also allow the traction current to flow from one track circuit section to another track circuit section through it, without being isolated by the rail insulation. [0003] The choke transformer box is installed on both sides of the track, because the size of the choke transformer box on both sides of each track is not uniform, and the texture of the choke transformer box itself is less, and there are stakes and signal lights installed on both sides of the track Therefore...
