Abstract
This paper provides an up-to-date review of research efforts in thermal camera and target object recognition techniques based on two-dimensional (2D) images in the infrared (IR) spectra (8-12μm). From the geometric point of view, a special target plate was constructed with a radiation source of lamp excited that allows all of these devices to be calibrated geometrically along a radiance-based approach. The calibration theory and actual experimental procedures were described, then an automated measurement of the circle targets by image centroid algorithm. The key parameters of IR camera were calibrated out with 3 inner and 6 outer of Tsai model in thermal imaging. The subsequent data processing and analysis were then outlined. The 3D model from the successful calibration of a representative sample of the infrared array camera was presented and discussed. They provide much new and easy way to the geometric characteristics of these imagers that can be used in car-night-vision, medical, industrial, military, and environmental applications.
