<p>Method and apparatus for capturing and processing images of terrain 6, comprising: using each of a plurality of cameras (14, 5 16, 18, 20) to capture an image of a surface of the terrain thereby producing a plurality of camera images. Each camera image comprises a plurality of pixels and are registered to create a plurality of sets of registered pixels, which are then classified. Ground penetrating radar (8), captures a radar image (24) of the terrain and a detection algorithm is performed on the radar image (24) to detect an at least partially subterranean object or a terrain feature (26) in the radar image. The detected object or terrain feature (26) is associated with at least one classified set of registered pixels (28, 30), preferably by projecting at least part of the object or terrain feature and at least one camera image onto a common plane. Classification of the pixel sets may be achieved by determining a spectral signature and comparing it to a spectral stored in a database. Preferably, the frequency range of each camera overlaps at least partially with that of another camera. The camera may respectively detect the following frequencies: ultraviolet, visible light, and infrared.</p> |
