Automated Visual Inspection

 

These projects involve interdisciplinary collaboration between the Computer Vision and Robotics Laboratory in the Beckman Institute and the Railroad Program in the Civil and Environmental Engineering department. The goal of these projects is to advance the state of the art in automated train inspection using computer vision techniques to show the feasibility of system of this type being implemented in the transportation field.

IMG_2886Track Inspection Using Machine Vision

 

This project focused on automatically inspecting the condition of the track by identifying defective components, such as track fasteners and turnout components, using computer vision. Video was acquired by mounting cameras on a custom-build track vehicle.

LPC_Me_Train-mwIntermodal Load Monitoring Using a

Wayside Machine Vision System

 

This project involved the monitoring of the loading of intermodal trains to provide an aerodynamic analysis of the entire train to estimate its fuel efficiency. Two wayside sites were developed and tested with in-service trains on a the BNSF railroad mainline in Sibley MO.

Heavy haul railcars must be visually inspected frequently to ensure the structural stability of the railcar underbody. The goal of this project was to determine a method for inspecting underneath moving railcars. A commercial system based on this work has been developed and is commercially available.

VulcanBackground-smallMachine Vision Inspection of

Railcar Safety Appliances

 

Inspectors and carmen use safety appliances to mount and dismount railcars during yard operations. It is critical for their safety that these laters, handholds and sillsteps are in good condition. A machine vision system was designed and later implemented by two commercial vendors for operation on sevaral major railroads.

ic4_spring-smallMachine Vision Inspection of

Railcar Safety Appliances

 

This was the first interdisciplinary project, in collaboration with the Civil Engineering Railroad Program, for developing a machine vision system to perform railcar inspection. The railcar "truck" components detected for inspection where the wheel, the bearing endcap bolts, the spring nest, and the break shoe.
