Paper Abstract

Technological advances in digital imaging and liquid crystal tunable filters allow for a design of a both compact and cost effective multispectral camera system. Thus an image acquisition system for the visible and near infrared wavelength range can be realised consisting of conventional CCD cameras and tunable filters whose spectral transmittace is controlled electronically. Due to their limited internal payload the use of a lightweight, compact camera system is of particular importance for applications involving mini-unmanned-aerial-vehicles (mini-UAVs). Within the scope of this paper a both compact and economical data acquisition system for multispecral images is described. Despite of their limited functionality (e.g.regarding calibration) in comparison with commercial systems such as AVIRIS the use of these upcoming compact multispectral camera systems can be advantageous in many applications. In order to maintain the systems low weight and price this work proposes to separate data acquisition and processing modules, and transmit pre-processed camera data online to a stationary high performance computer for further processing. Special focus is laid upon transmission paths with limited bandwidth.
