Problems solved by technology

[0004] Most of the current fastener inspections are mainly manual inspections. The patrol workers conduct on-the-spot inspections of the track lines. This method requires the patrol workers to carry a patrol bag with a weight of about 10 kilograms. The patrol length is about 20 kilometers, and the labor intensity is high. , and the working environment is harsh, safety cannot be guaranteed at all, the accuracy of detection is greatly affected by human subjectivity, there are a large number of missed and wrong detections, and effective detection cannot be carried out in remote areas

Embodiment Construction

[0058] All features disclosed in this specification, or steps in all methods or processes disclosed, may be combined in any manner, except for mutually exclusive features and / or steps.

[0059] Any feature disclosed in this specification, unless specifically stated, can be replaced by other alternative features that are equivalent or have similar purposes. That is, unless expressly stated otherwise, each feature is one example only of a series of equivalent or similar features.

[0060] Such as figure 1 Shown, the technical scheme that the present invention adopts comprises:

[0061] Step 1: Obtain an image containing fasteners.

[0062] Step 2: Locate the position of the fastener in the image once. Those skilled in the art know that the fasteners are located on both sides of the sleeper rail. When the image acquisition device is installed on the bottom of the train and the camera position is adjusted, it can be ensured that the sleeper rail is always in the middle of the ima...

Abstract

The invention discloses a railway fastener positioning algorithm and a device based on geometric matching, and relates to the technical field of railways, in particular to a railway fastener positioning algorithm based on image processing. The technical solution adopted by the present invention includes: step 1: acquire an image containing a fastener; step 2: perform a positioning on the position of the fastener in the image; step 3: perform a positioning on the fastener in the image area obtained by one positioning The secondary positioning area is obtained by template matching; step 4: perform feature recognition on the fastener in the secondary positioning area, and determine the position coordinates of the fastener.

Description

technical field [0001] The invention relates to the technical field of railways, in particular to an image processing-based positioning algorithm for rail fasteners. Background technique [0002] With the rapid advancement of my country's railway development, as of now, the national railway operating mileage has reached about 120,000 kilometers. The daily railway traffic volume is unprecedented. How to ensure the safe, stable and uninterrupted operation of trains has become an important mission of Chinese railway personnel. [0003] Railway line equipment is the basic equipment of the railway transportation industry. Reasonable maintenance of railway line equipment and timely and effective analysis, prevention and remediation of line equipment diseases are the keys to ensure safe railway transportation. In line maintenance, the daily inspection of fasteners is one of the necessary inspection items. Fasteners are key components for fixing rails on sleepers to maintain gauge...
