A method and an apparatus determines a geometry of a scene by projecting one or more output image into the scene, in which a time to project the output image is t. Input images are acquired of the scene, in which a time to acquire each input image is t, and in which t>tand in which the input image includes a distinguishable stripe of pixels with an edge due to t>t. An amount of distortion of the edge is measured from a straight line to determine a geometry of the scene.
