Problems solved by technology

Therefore, the method of detecting the wheelbase cannot identify the same type of carriages in different countries
Moreover, sometimes the carriage is refitted (such as changing a passenger car to an insulated car, changing from carrying passengers to carrying goods) so that the objects to be carried change, but the axles usually remain the same, which makes it impossible to distinguish the objects carried in the carriage by detecting the axles

Abstract

The application relates to a train type identification method and system and a safety inspection method and system. The train type identification method according to the present disclosure includes using a line array camera that moves relative to the inspected train to continuously take pictures of the inspected train to generate multiple train sub-images, and splicing the multiple train sub-images to obtain the train of the inspected train image, extracting at least one train characteristic parameter from the train image, comparing the at least one train characteristic parameter with a pre-stored model template, and automatically determining the model of the inspected train according to the comparison result.

Description

technical field [0001] The invention relates to the field of train safety inspection, in particular to a train type identification method and system, and a train safety inspection method and system. Background technique [0002] Train type recognition has many applications in practice, such as in the field of train safety inspection or train maintenance. In the field of train safety inspection, it is necessary to distinguish different models to determine whether the inspected model is carrying people, so as to set different X-ray doses, or only perform X-ray scanning on the cargo compartment and not on the passenger compartment. This just needs to first identify the vehicle type to judge whether the vehicle type entering the inspection area is a passenger locomotive or a passenger car. [0003] Train models can be roughly divided into locomotives, passenger cars, trucks and other types, and trucks are further divided into container trucks, box cars, oil tank cars, board car...
