A real-time screening method for choke transformer box images based on image recognition of rail waist plug nails

Abstract

The invention provides a method for real-time screening of box images of choke transformers based on image recognition of rail waist plug nails. It includes the following steps: S1: After the inspection starts, send a trigger signal to start the camera of the rail plug and the box camera of the choke transformer to start continuous acquisition; S2: perform target detection on the images collected by the camera of the rail plug, and if If the result contains rail plug nails, start the choke transformer box camera to extract images from the cache; S3: filter out the images containing the choke transformer box and store them. In this method, the detection result of the rail waist plug is used as the trigger signal for the choke transformer box to collect and store the image of the camera, and a classifier is used to judge whether the image to be tested contains the rail waist plug, which can ensure that the choke transformer box is not missed. Reducing images that do not contain choke transformer boxes under the premise can improve the detection efficiency of choke transformer boxes and enhance the real-time performance of the image screening process.

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...
