specific Embodiment approach 1

[0042] Specific implementation mode one: refer to figure 1 and figure 2 Specifically explaining this embodiment, a method for image recognition of a damaged bathtub of a railway freight car described in this embodiment includes the following steps:

[0043] Step 1: Obtain the linear image of the passing truck, locate the bathtub area from the image, and perform cropping;

[0044] Step 2: Use the trained deep learning model to segment the image corresponding to the bathtub;

[0045] Step 3: According to the segmentation results of the deep learning model, the image processing method is used to further obtain the information of the segmented parts, and the bathtub damage is judged according to the prior knowledge.

[0046] 1. Image preprocessing

[0047] (1) Image collection

[0048] By building high-definition equipment around the truck tracks, high-definition line scan images of passing trucks are obtained. As truck components may be affected by rain, mud stains, oil sta...

Abstract

An image recognition method for damaged bathtubs of railway freight cars, which relates to the technical field of freight train detection, aims at detecting faults by manually inspecting images in the prior art, because inspectors are prone to fatigue and omissions during the work process, resulting in For the problem of low detection efficiency, the present invention uses image processing and deep learning methods to automatically identify bathtub faults, and only needs to confirm the alarm results manually, which can effectively save labor costs and improve detection accuracy. The present invention applies deep learning algorithms to In the automatic identification of bathtub damage faults, the stability and accuracy of the overall algorithm are improved; since the background of the bathtub board is an ever-changing floor image, the FasterInception network is used to detect whether the image contains a bathtub, and then the U‑NET network is used to detect whether the image contains the bathtub. Subimage detection faults, reducing the impact of images that do not contain bathtubs on segmentation results.

Description

technical field [0001] The invention relates to the technical field of freight train detection, in particular to an image recognition method for a damaged bathtub of a railway freight train. Background technique [0002] The broken fault of the bathtub of the truck is a fault that endangers the driving safety. At present, manual inspection of images is mostly used for fault detection. As the inspectors are prone to fatigue and omissions during the work process, resulting in missed inspections and wrong inspections, affecting driving safety. The method of automatic image recognition can improve the detection efficiency and stability. In recent years, deep learning and artificial intelligence have continued to develop and mature in technology. Therefore, using deep learning to identify the damaged fault of the truck bathtub can effectively improve the detection accuracy. Contents of the invention [0003] The purpose of the present invention is to propose a bathtub for r...
