Abstract
In this work we present an algorithm used to automatically register a sequence of ladar images taken from a sensor flying a known flight path . The registration is performed with no human operator intervention. The resulting mosaic is accurate to one pixel. The algorithmic approach was developed in such a way to allow for near real time processing. The initial method can be extended to registration of multiple views of a scene, with four degrees of freedom (translation and in plane rotation). In this work we will restrict ourselves to rigid body transformations. The registered mosaic is an important step in geolocation using a reference digital elevation map, and will be explored in future work.
