Abstract
A 3D MultiSpectral Lidar. The system comprises a laser transmitter light source, a laser detection assembly, optics that couple the outgoing and incoming laser signals, a digital camera assembly for collecting passive light, a position and orientation system, and processing hardware. The system provides real-time georectified three dimensional images and topography using an airborne platform. The system collects time-synchronous lidar range and image data in an optical receiver. The individual images are then mosaiced and orthorectified in real-time. The lidar range data and image data are then coupled to a position and orientation system to transform the three dimensional range images to a single geographically referenced multispectral three dimensional image.
