Rail Straightness Inspection after 3D Scan Demonstration

DREAMTNS.LTD, RIEGL’s distribution partner based out of South Korea, performed a “Rail Straightness Inspection” demonstration with the RIEGL VZ-400i and the PointShape Inspector software to find out how precisely they could inspect the straightness of rails.


The RIEGL VZ-400i was used for 3D scanning & post-processing for this test project. The rail measured is 25m long, clearly bent and the 3D data had to be acquired within 5 minutes. The team scanned some sample rails directly after production. The PointShape Inspector software was able to check bending inspection with the Straightness GD&T feature.


The rail in the yellow box was the test object for the straightness analyzing.
