Triangulation method for distance measurements
Triangulation method is used for measuring 2D and 3D product parameters. The product is illuminated by a light line (usually a laser), and the resulting light footprint is scanned. By calibrating the camera system, the position of the light footprint in the room is then calculated and the required parameters are measured or the geometry is checked.
Measurement can take place in rotation, linear motion, or static position of the object.
Typically, this method is used for measuring and checking rolled or stretched products, measuring samples, robot navigation, checking the correct shape of a product, etc.
Measurement accuracy is up to ± 0.01 mm.
Selected solutions for this method:
The measurement of profiles of rolled products online is a contactless device that allows laser measurement of profiles of rolled cold and hot products directly in operation.
A stand-alone operating equipment device for accurate 3D measurement of the dimensions of samples under heavy conditions of metallurgical operation.
