摘要

摘要:折反射周视系统作为近十几年发展起来的一种新型周视视觉实现形式，相比相机旋转扫描、多相机图像拼接和鱼眼镜头大视场成像等常规方法，在小型化、结构灵活性、成本和实时性方面具有优势。本文综述了折反射周视系统的成像模型、系统标定、畸变校正和全视场清晰成像等基本问题研究状况，讨论了折反射周视系统在红外成像和立体视觉领域的扩展应用研究现状，最后总结了目前存在的问题，并提出未来折反射周视成像系统将围绕非单视点成像模型、提高空间分辨力的方法和处理算法实时实现开展研究。

Abstract:As a new panoramic vision system developed in recent 10 years, the catadioptric panoramic system has advantages in miniaturization, structural flexibility, low cost and real-time compared to conventional methods such as camera rotation scanning, multi-camera image stitching, and fisheye lens large field imaging. In this review, the recent progress in basic catadioptric panoramic system, including imaging models, system calibration, distortion correction and overall well-focused imaging, are summarized. Moreover, the extended applications in infrared imaging and stereo vision are also presented. Finally, the existing unsolved problems are discussed. It is also suggested that the future catadioptric panoramic system will focus on non-single view imaging model, improving of the spatial resolution method and implementing of the real-time processing algorithm.
