多尺度大视场十亿像素成像技术

十亿像素相机可以获取信息量较大的图像，在天文观测、航空航天遥感等领域具有广泛的应用前景。受探测器和光学设计水平的限制，传统的大视场十亿像素成像通过小视场相机扫描和图像拼接实现。为解决传统十亿像素相机实时性不高的问题，文章研究一种新型多尺度大视场十亿像素成像技术，从实现十亿像素成像的条件出发，阐述该技术的原理、优势及应用领域；分析系统独特的技术指标，包括物理锥角、重叠率等，梳理和归纳新型多尺度大视场十亿像素成像系统走向实用化过程中必须克服的关键技术。研究结果表明，该技术可在不提高系统复杂性的情况下大幅提高监视实时性。

Multiscale Wide Field-of-view Gigapixel Imaging Technique

Gigapixel imaging camera can capture images with huge information, and is very useful in as-tronomical observation, airborne and spaceborne remote sensing, and so on. Constrained by detector and optical designing level, traditional gigapixel camera with large field of view usually captures images through scanning and mosaicking, which causes large areas unobserved within the time frame of a single acquisition. To overcome this problem, this paper researched a new multiscale gigapixel imaging technology. The paper first introduces the requirements of realizing gigapixel imaging, and then describes the imaging principle, advantages and ap-plication areas were shown. The unique technique parameters including physical cone-angle and magnification are analyzed. Finally, the key technology for realization of this new concept of multiscale gigapixel imaging is given. The results show the new gigapixel imaging technology can improve surveillance efficiency without adding systematic complexity.
