Abstract

Target detection in 3-dimensional (3D), irregular point cloud data sets is an emerging field of study among the remote sensing community. Airborne topographic light detection and ranging (i.e., Lidar) systems are capable of scanning areas with single-pass post spacings on the order 0.2 m. Unfortunately, many of the current spatial search algorithms require higher spatial resolutions on a target object in order to achieve robust detection performance with low false alarm levels. This paper explores the application of Johnson's spin-image surface matching algorithm to low density point clouds for the purpose of providing a preliminary spatial cue to a secondary sensor. In the event that this sensor is an imaging device, a method is presented for transforming 3D points into a fixed, gridded coordinate system relative to the second sensor.
