Embodiment Construction
[0054] The present invention will be further described below in conjunction with drawings and embodiments.
[0055] Such as figure 1 Shown is the general flow chart of the present invention; The inventive method is by testing the outdoor car target scene and the civilian house target scene in the woods, and the experimental results show that the polarization difference between the artificial target and the natural background can be fully utilized, and the polarization characteristics The image and the infrared intensity image are fused, and the specific steps are as follows:
[0056] (S1) Acquisition and preprocessing of infrared polarization image information
[0057] Use the long-wave infrared polarization imaging detection system to collect no less than three channels of the target scene (different analysis directions, such as I 0° , I 60° , I 120° ) of the infrared polarization image, the Stokes polarization state can be calculated. Image preprocessing includes image ...
