Abstract

A versatile system for collecting and analyzing multispectral images is described. This innovative system uses state-of-the-art video and microprocessor technology to collect and digitize image data in real time; an IBM-PC compatible unit is used as the host computer. The solid-state video camera is designed to automatically collect sequential multispectral images, at the rate of 60 images per second, in six user-defined spectral bands. Data can be recorded and displayed using standard video equipment. The system is small, rugged, light-weight, and suitable for collecting field data for diagnostic or surveillance purposes, from ground level or from aircraft. An automatic, focal plane, shuttering system permits collection of blur-free images of rapidly changing scenes. The microprocessor-based digitizer has programmable resolution and digitizes complete spectral sequences in real time. Software is provided for collection and display of images and to facilitate histogram, ratio, and spectral time series analysis. Other software tools are provided for various image processing tasks including the construction of color composite spectral images. The elements of this system and their performance are described in this paper, and issues of resolution and calibration are discussed.
