Detection probability of infrared and visible image fusion system
A method to calculate the target detection probability quantitatively for a infrared and visible image fusion system was proposed and a corresponding calculation model was established. First
the main factors affecting on the target detection probability were analyzed
and they were the spectral contrast of target and background
the characteristics of infrared and visible light detector
environmental illumination conditions
the integration of image quality
and the target size and distance. Then
five mathematical models on the effect factors mentioned above was constructed. On this basis
a calculation model for the detection probability based on infrared and visible image fusion system was completed. Finally
the experiments for two practical missions were performed. The first experiment show its results as follows: target detection probability of trees for a single detection system pvis is 0.294 8
pIR is 0.136 0
but the detection probability for the fusion detection system is 0.414 2
much higher than that of single detector
which verifies the validity of the calculation method of fusion system for target detection probability. It proves that the fusion image quality and the spectral characteristics of goal itself play important roles for target detection probability. Moreover
the experiment results of the model is accord with the human visual characteristics as well.
