ABSTRACT:
A portable multispectral data acquisition system for use on a vehicle such as an aircraft comprises a plurality of gyroscope-stabilized remote sensing devices synchronized to simultaneously capture images of a common spatial area in both visible and invisible bands of the electromagnetic spectrum, a computer and digital recorder to record and correlate the captured images with temporospatial reference information, image processing software to stack or layer the images and to extract and compare the images in order to identify and filter hidden or subsurface anomalies that are invisible to the naked eye, and additional image processing software to orthorectify the images to a three-dimensional digital terrain map and to stitch adjacent images together into a mosaic. Methods for using the portable multispectral data acquisition system are also provided.
