Depth measurement by triangulation using a CCD camera and a projected laser stripe is well established. To obtain an image, rather than a profile, movement of either the stripe or the scene is required. We show that improper assumptions or errors in calibration of the scanning motion result in significant errors in image acquisition and describe and illustrate a procedure to rectify this. © 1998 Elsevier Science B.V.
