Title:
WATER JET RAIL GRINDING CAR DIRT BLOWING AND SUCTION METHOD AND SYSTEM BASED ON IMAGE PROCESSING
Document Type and Number:
WIPO Patent Application WO/2023/197566
Kind Code:
A1
Abstract:
A water jet rail grinding car dirt blowing and suction method and system based on image processing, the method comprising: foreign matter detection cameras (63) collecting original surface feature images of a rail and a ballast bed, and then transmitting same to a foreign matter visual processing system; the foreign matter visual processing system performing calibration point extraction and matching on a template image by means of a camera calibration module to obtain calibration parameters; importing the calibration parameters into an image processing module and performing image preprocessing, and performing coordinate transformation restoration on the preprocessed image by means of a calibration parameter matrix; a foreign matter recognition and location module performing detection of foreign matters on the rail on the basis of template matching and genetic algorithm, and acquiring rail foreign matter detection data; a data processing module carrying out storage, search and analysis on the rail foreign matter detection data and generating a dirt blowing and suction solution; and, according to a visual detection algorithm, recognizing and locating foreign matter attachment information of each area, and intelligently controlling the dirt blowing and suction strength of each area, thus achieving self-adaptive cleaning for grinding scraps and dirt on the whole rail.
