Claim One:
1. A method for automated assignment of geodetic coordinates to pixels of images of aerial video, comprising: generating, with a processor, a first estimated camera model for a first video frame of the aerial video; applying a Lidar digital elevation model (DEM), with the processor using the first estimated camera model to register the first video frame; applying, with the processor, a plurality of iterative refinements to the first estimated camera model for the first video frame by composing the first estimated camera model for the first video frame with the Lidar DEM registration to generate a refined registration of the first video frame; sampling, with the processor and with reference to the first estimated camera model, the refined registration of the first video frame on a surface of the Lidar DEM to orthorectify the refined registration of first video frame; generating, with the processor, at least a second estimated camera model for a next video frame of the aerial video by registering the next video frame to the orthorectified refined registration of the first video frame and composing the at least the second estimated camera model of the next video frame with the orthorectified refined registration of the first video frame; sampling, with the processor and with reference to the at least the second estimated camera model, the next video frame on the surface of the Lidar DEM to orthorectify the next video frame; repeating the generating and the sampling for subsequent video frames of the aerial video; and assigning, with the processor, geodetic coordinates to pixels of images in the first video frame, the next video frame, and any subsequent video frames of the aerial video.
