由于鹰眼的特殊视觉机制,其具有大视场搜索、远距离探测和高分辨率成像等优点。基于鹰眼视觉原理,针对弹载光电探测平台,探索一种可以在大视场范围进行目标搜索,同时在关键区域进行目标自动定位和高分辨率成像的智能探测方法。在长波红外谱段,设计了五孔径大视场高分辨成像系统。基于Agent智能控制理论,提出了多传感器智能协同控制方案,实现大视场范围下的目标自动定位。研究了多孔径图像拼接和变分辨率图像融合方法,实现了大视场背景图像和高分辨目标图像的整体获取。研究结果表明,设计的多孔径探测系统可有效解决弹载环境下远场探测过程中大视场与高分辨的矛盾问题。

Because of its special visual mechanism, eagle eye has several advantages, such as a wide field of view, remote detection, and high-resolution imaging. In this paper, based on the eagle-eye vision, an innovative and intelligent detection method is presented that can automatically search for specific targets in key areas and create high-resolution images aimed at being part of a missile-borne optical-electric detection platform. In the long-wave infrared spectrum, a high-resolution imaging system is designed with five apertures. Based on the Agent intelligent control theory, a multisensor collaborative control scheme is established to realize automatic target positioning in a wide field of view. The multi-aperture image mosaic and variable resolution image fusion methods are studied to achieve the overall acquisition of large field of view background and high-resolution target images. Results show that our multi-aperture detection system can effectively solve the contradiction between large field of view and high-resolution in the far-field detection under an optical dome environment.
