Results of the point-correspondence algorithm in the Computer Science Building. (a) Numbers label the detected points on the image and the corresponding matched points on the floor plan. (b) The floor plan is warped into the image space and overlaid on the original image. This example has 10 image points and 32 map points and completes matching in about 4 seconds. November 1, 2009
