Abstract
A method for depth mapping includes operating a projector at a first temperature to project a pattern of optical radiation onto a reference plane, capturing a first image of the projected pattern on the reference plane, using the first image and an optical and thermal model of the projector to compute multiple reference images associated with different respective temperatures of the projector. Using the projector, the pattern is projected onto a scene, and a temperature of the projector is measured while projecting the pattern. The method further includes capturing a second image of the projected pattern on the scene, selecting one of the reference images responsively to the measured temperature; and computing a depth map of the scene by comparing the pattern in the second image to the selected one of the reference images.
