Embodiment Construction

[0058] In the process of the invention, the inventor has studied and tested many times, and when considering the problem of how to reduce the detection workload of the detection post, he has also thought about following the conventional way of thinking of "enhancing the automaticity of detection" (ideal The result is: all detections are automatically carried out by machines without manual participation), but it cannot be supported by the current technical reality (the detection accuracy of various detection methods is low), because the lack of detection due to low accuracy leads to the train The harm caused by security is immeasurable. Based on this, the inventor thought of the method of "providing only abnormal images (or images suspected of abnormality) to the inspectors" (hereinafter referred to as the method of "selecting abnormal images") to reduce the number of images provided to inspectors. quantity, thereby reducing the detection workload of the vehicle inspectors and ...

Abstract

The invention relates to an image processing method and device and a train fault detection system. The method comprises the steps of collecting a plurality of images of each carriage of a train; sequentially using the images as current processing images to conduct abnormal detection process so as to confirm abnormal images and mark abnormal areas on the images; providing the abnormal images on which the abnormal areas are marked for train inspection station equipment. According to the method, each collected image is detected in a preset mode, only the abnormal images are provided for detecting staff, and the number of images needing watching by the detecting staff is reduced, so that the detecting workload of train inspection staff is reduced, working efficiency is improved, transmission data volume in a remote transmission process is reduced, and the consumption of transmission resources is reduced.

Description

technical field [0001] The invention relates to the technical field of train fault processing, and more specifically relates to an image processing method and device for train fault detection and a train fault detection system. Background technique [0002] With the development of railway technology, the automation of various tasks is increasing day by day. For example, the detection of train faults has shifted from on-site manual detection of vehicles to the analysis of vehicle images, that is, taking images of various positions or parts of the train, and then manually The image is analyzed to determine whether there is a fault, without the need for inspectors to visit the scene in person, and the train does not need to stop because of the train inspection, which improves the transportation efficiency. [0003] However, the image analysis provided by the above-mentioned prior art replaces the actual detection method, although it can provide the convenience of detection to a...
