Embodiment Construction

[0050] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0051] An embodiment of the pole number positioning method applicable to the complex scene along the track of the present invention

[0052] The present invention first uses image filtering, morphology and other means to preprocess the picture, and then locates the pole number according to the edge feature and texture feature, and performs digital recognition of the pole number. Recognition rate. The whole process is as image 3 As shown, it mainly includes the following steps:

[0053] 1. Collect the scene images along the track, and preprocess the collected scene images to make the images easy to segment and identify.

[0054]The preprocessing process first scales according to the width of the utility pole in the image, so that the width of the utility pole after scaling is 10 to 20. Generally, the reduction factor is an integer multipl...

Abstract

The present invention relates to a pole number positioning and identification method suitable for complex scenes along the track. The present invention firstly performs preprocessing of reduction and median filtering on the scene images collected along the track, and then uses a sobel filter with a large dimension Find the edge, and then use the Hough transform to detect the strongest edge, that is, determine the position of the utility pole, and then use the number plate co-occurrence matrix texture feature to locate the digital area; then carry out the digital recognition of the pole number, filter the image, and The 64-dimensional features of each digital image are obtained by valueization and segmentation, and the training model is used for recognition. After the number plate recognition is completed, all the recognition results will be reprocessed, and the number plate will be self-corrected according to the unique properties of the number plate. , through self-calibration, the recognition rate of the number plate is over 90%.

Description

technical field [0001] The invention relates to a pole number positioning and identification method suitable for complex scenes along a track. Background technique [0002] With the continuous improvement of the overall scale of the railway, the speed is continuously accelerated, and the running interval is continuously shortened, resulting in the safety of the railway becoming more and more important, and the detection task is becoming more and more heavy. The traditional method of manual inspection along the line is far from being able to adapt to the rapid development of railways, and the use of machine vision has become the general trend. [0003] In order to ensure the order of high-speed railway operation and improve the safety and reliability of power supply, the Ministry of Railways has established a high-speed railway power supply safety detection and monitoring system (6C system), hereinafter collectively referred to as the 6C system. Its purpose is to carry out a...
