| Popis: | The infrared imaging technology can acquire the intensity information of targets, and polarization imaging technology can acquire the polarization information of targets. Combination of the two technology is more conducive to the target detection and recognition. Experiments focused on typical targets under typical backgrounds, such as the plane in the sky, the ship on the sea, and the vehicle on the grass. In Experiments, the four-channel long wave infrared polarization imaging (LWIPI) system developed was employed to acquire images. Experimental results show that, compared with traditional long-wave infrared images, LWIPI has the following advantages:(1) the long wave infrared polarization degree image has a higher image contrast in a certain situation, which is beneficial to the target detection and recognition; (2) the long wave infrared polarization angle image can highlight target details, which is beneficial to the viewer's understanding of the content of the scene; (3) the long wave infrared polarization degree image and angle image can suppress clutter in a certain situation, which is beneficial to target imaging studies under the condition of a clutter. |
