Reconstruction of 3D objects from UAV EO imagery yields useful information, but can be time consuming and computationally expensive. View planning reduces processing time by selecting the optimal image set needed to reconstruct a scene. This paper demonstrates how view planning is used in a targeted manner to select a subset of images from a large existing image set to model specific vehicles or structures. Potential applications of the method include enabling 3D target classification algorithms and rapid geo-location. The method could also facilitate on-board reconstruction. The view planning algorithm is tested on five different targets, and is shown to reduce processing time for target models by up to a factor of 50 with little decrease in accuracy.
