Abstract :
Based on the formula of image radiation, the influence of distance on the temperature measurement accuracy using IR thermal is analyzed in theory. A algorithm for correction based on neural network is proposed. The error caused from the difference between measuring distance and calibrated distance is reduced by correction when measuring in a short distance.
