A sleeper recognition method and system based on image recognition and recognition code recognition

Abstract

The invention relates to a sleeper recognition method and system based on image recognition. The method includes generating an identification code for fixing on the corresponding sleeper according to the number of the sleeper; The identification code or the fastener is photographed, the image information of the sleeper identification code or the image information of the sleeper fastener is obtained, and the sleeper information containing the corresponding sleeper number and real-time mileage information is determined according to the image information of the sleeper identification code or the image information of the sleeper fastener; Update the sleeper information to the pre-established sleeper database. In the present invention, the identification code is set on the sleeper in advance, and then the identification code or fastener on the sleeper is photographed to obtain the image information of the identification code of the sleeper or the image information of the fastener of the sleeper, and then determine the sleeper number and real-time mileage information of the sleeper, and Updated to the sleeper database, the detection accuracy is high, and the maintenance cost is greatly reduced. At the same time, the installation and detection are very convenient, and it is very suitable for large-scale promotion and use.

Description

technical field [0001] The invention relates to the technical field of sleeper maintenance, in particular to a sleeper recognition method and system based on image recognition and recognition code recognition. Background technique [0002] The rapid detection technology of railway track geometric state is the development trend of railway track geometric state detection, and the track inspection trolley developed at home and abroad is the carrier of this technology. The track inspection trolley integrates various sensors such as wireless communication, sleeper recognition, inertial navigation system, distance measurement, and angle measurement. The sleeper recognizer is an important part of the track inspection trolley. Its detection accuracy directly reflects the quality and accuracy of track detection. When fine-tuning the track, it is necessary to know the exact mileage of the sleeper. The mileage of the existing track alignment may not be accurate. The number of sleepers...

Problems solved by technology

The sleeper recognizer is an important part of the track inspection trolley. Its detection accuracy directly reflects the quality and accuracy of track detection. When fine-tuning the track, it is necessary to know the exact mileage of the sleeper. The mileage of the existing track alignment may not be accurate. The number of sleepers may be wrong, and the distance between sleepers may be inaccurate. When fine-tuning the track and other operations, it is necessary to know the number of each sleeper accurately. When a sleeper is missed or wrongly detected, it will directly affect the The accuracy of all subsequent data detection and the detection quality of the entire data will affect the quality of track fine-tuning

At present, the method of mileage positioning and sleeper number identification is commonly used in railway track detection, but the mileage will have errors, and the method of brushing the sleeper number is costly and takes a long time, so a simple, effective and economical method is needed for identification Sleepers are used for positioning sleepers and track fine-tuning
