Train Wheel Abrasion, Measurement Method Using Contour Information
نویسندگان
چکیده
We present a method to recognize a complicated curved object from an image contour. We are developing a system that automatically measures train wheel abrasion from its contour image. Because a train wheel consists of a curved surface, the transformation of the image contour due to position variation affects the measurement accuracy. The 3D shape model of the train wheel is analyzed to compute on image contour model represented with a numerical equation. The system corrects the measured value using the relation between position variation and contour model. Experimental result shows that the system can measure train wheel abrasion with an objective accuracy.

متن کاملResidual Stresses Measurement in Hollow Samples Using Contour Method
Residual stresses are created usually undesirably during manufacturing processes, including casting, welding, metal forming, etc. Residual stresses alone or in combination with other factors can cause the destruction and fracture of components or significant decline in their service life. Therefore, it is crucial to measure the residual stresses. Contour method is a destructive testing method c...
