Accurate positioning and recognition method for train number on basis of deep learning

Abstract

The invention provides an accurate positioning and recognition method for a train number on the basis of deep learning. The accurate positioning and recognition method comprises the steps of: collecting a train panoramic image, and carrying out size adjustment on the train panoramic image; constructing a train number positioning network, and taking an adjusted panoramic image as a training set totrain the train number positioning network; training a train number identification network according to the train number area output by the train number positioning network; performing size adjustmenton a to-be-identified train panoramic image, and inputting an adjusted train panoramic image into a trained train number positioning network so as to obtain an accurately-positioned train number area; and inputting the train number area into a trained train number identification network for identification so as to obtain a train number digital identification result. With the accurate positioningand recognition method provided by the invention, the train number sequence with any length can be processed; the defects of low positioning accuracy and difficulty in distinguishing small-size vehicle numbers for manual features in a complex scene and a conventional deep learning method are overcome; meanwhile, character segmentation is not involved; and overall recognition is achieved.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to a method for accurately locating and identifying train numbers based on deep learning. Background technique [0002] The automation of train inspection and cargo inspection operations is an important goal of railway informatization. As one of the basic tasks of inspection automation, the positioning and identification of train numbers can automatically record the number information and avoid consuming huge manpower and material resources. When an abnormal condition of a freight train or a passenger train is detected, the train number information is automatically used as a sign of the identity of the train, linked with the safety status information of the equipment, and an alarm is sent to the control center. Therefore, train number identification is used in train inspection and It is particularly important in the automation of cargo inspection operations. [0...
