Abstract:

We investigate the advantages of a stereo, multi-spectral acquisition system for material classication in landscape scenes. To obtain additional bands of spectral information, and to ensure a high spatial resolution, we use commodity hardware to create a stereo, multi-spectral capture system. Whilst alternative systems are either slow or impractical when considering ground-level image acquisition, our resulting system allows for fast, simple, hand-held multi-spectral image acquisition. We show that foliage classication using images acquired with our 6-band design compares favourably to simply using a standard RGB camera.
