An accurate method for the extraction of line structured light stripe

In order to improve the accuracy in the On-line measurement of rail profile with a line structured light based on machine vision, the accurate extraction of a structured light stripe is a necessary and key step.An accurate extraction method is proposed for the structural light stripe in practical applications.The structured light stripe is separated and extracted accurately based on the geometric characteristics of the structure light stripe in the binary image.And the noise in the captured image is removed with region segmentation method.The above method was tested in laboratory conditions.Experiment results show that the developed method can effectively solve the problem of the accurate extraction of structured light stripe in real time.
