Abstract

Emerging dual-camera dual-band (DCDB) infrared camera systems are playing an increasing role in temperature estimation and range measurement. This paper discusses the optimal design of a DCDB imaging system that makes use of contemporary filter fabrication technologies and improving detector performance. A two-color stereographic system allows for the temperatures of the objects to be measured without assuming a priori knowledge of emissivities, as well as providing a basis for estimating the distances to the objects. Multiple system design approaches are compared and key elements of the design trade space are described, including the selection of camera separation distance and specific infrared passbands. Analytical support for the methodology is provided by analyzing data from simulated infrared scenes. Finally, data from a laboratory-based DCDB system are analyzed and compared with model predictions.
