Railway track image processing method and system, storage medium and electronic equipment

Abstract

The invention is suitable for the technical field of railway track detection, and provides a railway track image processing method and system, a storage medium and electronic equipment. The method comprises the following steps of S100, acquiring railway track image data; S200, carrying out video coding on the image data to form a first type frame Ia and a second type frame group Pa; and S300, forming an image group Ga by using the first type frame Ia and the second type frame group Pa. Due to the fact that the image frames of the railway track have great similarity, the video coding principle is introduced, railway track image data is coded into a first type frame Ia and a second type frame Pab to form an image group Ga, a complete image is stored in the first type frame Ia, and difference data with the previous frame is stored in the second type frame Pab. Thus, through the differential compression mode, the compression rate of the railway track image data is greatly improved, and the image data size is reduced.

Description

technical field [0001] The invention relates to the technical field of railway track detection, in particular to a railway track image processing method, system, storage medium and electronic equipment. Background technique [0002] Railway track detection is an indispensable part of the safe operation of the railway network. During the railway track detection work, it is necessary to take pictures of the railway surface (including tracks, sleepers, fasteners, and roadbeds, etc.) to obtain image data of the railway as a tool for track detection. Basic data for archiving, defect analysis, retrieval and viewing; at the same time as the input of other systems for related processing (such as: defect detection, etc.). [0003] In the prior art, the method adopted for railway track inspection is to install an optical image acquisition device (usually a line array camera) at the bottom of the track inspection vehicle, and perform rapid image acquisition on the lower railway surface...

AI Technical Summary

Problems solved by technology

[0004] With the increase of the railway mileage and the improvement of the resolution of the camera equipment, the collected railway image data will be a huge amount of data, and the hardware cost required for storing and processing the huge amount of data is extremely high

At the same time, with the popularization of high-speed railways, the speed of track inspection vehicles increases, and the image compression speed of the front-end acquisition server is often lower than the image acquisition speed. As a result, the data collected by track inspection vehicles is too late to be compressed and lost, which seriously affects the collection results. completeness and accuracy of
