IR-visible image sensor for diagnosis of ground object

A monitoring system using both visible (VIS) and infrared (IR) images has been developed for the measurement of reflectance characteristics of land surface and buildings. An uncooled infrared detector array of monolithic 320 X 240 bolometers is used for the observation in thermal infrared region in the wavelength of 8 - 12 micrometers . Two images from a visible camera and an infrared camera, which are co-aligned on the same optical axis, are registered using an image processing board in real time. The registration error among images obtained at the same time is investigated. Using the system, temperature distributionof ground objects put out of doors is estimated, where the real-time identification between VIS and IR images is important.
