Passive autofocusing system for a thermal camera
Most of the Thermal (Infrared) cameras nowadays are equipped with a motorized lens for
focusing a scene manually. The subjective nature of manual focusing makes it an inefficient
and cumbersome process. In contrast, Autofocusing (AF) obtains the best focused image
based on a quantitative measure with the benefits of convenience and intelligence. Various
AF systems for visual cameras have been developed, but relatively less amount of work has
been done for thermal imaging systems. This paper presents a Vision and Control based …
