Abstract
A method for measuring three-dimensional coordinates of an object surface with a line scanner, the line scanner including a projector and a camera, the projector projecting onto the object surface a first line of light at a first time and a second line of light at a second time, the integrated energy of the second line of light different than the first line of light, the camera capturing the reflections of the first line of light and the second line of light, a processor determining portions of the image that are saturated or have electrical noise, and determining three-dimensional coordinates of the object surface based at least in part on the processed data.
