Fundamental Study of Very High Resolution Image Acquisition Method using Multiple Image Processing for Very High Resolution Image Communication

针对VHD图像采集成像系统的发展，提出了一种新的基于信号处理的方法来提高现有图像采集设备的空间分辨率。基于信号处理的图像采集方法通过处理和整合用多个不同相机同时拍摄的多个图像来产生具有足够高SNR的改进分辨率图像。经过理论分析和实验仿真，得到了以下结果：1.在两台摄像机光轴相交或对三维物体成像的情况下，一台摄像机拍摄的一幅图像的某个像素与另一台摄像机拍摄的另一幅图像的某个像素几乎重合。2.另一方面，利用像素孔径不同的多个相机使我们能够消除这种非均匀改善问题，因为在不同孔径的情况下，与相同孔径的情况不同，用一个照相机拍摄的一个照相机的像素决不会与用另一照相机拍摄的另一照相机的任何像素重合在这项研究中，我们显示了利用多个相机在其像素孔径不同的优势，但它需要研究鲁棒的配准算法，即使在严重的混叠效应和适用于不同的孔径的情况下。

Aiming at the development of an imaging system for acquiring VHD images, we presents a new signal-processing based approach to improve the spatial resolution of existing image acquisition devices. The signal-processing based image acquisition method produces an improved resolution image with sufficiently high SNR by processing and integrating multiple images taken simultaneously with multiple different cameras. After the theoretical analysis and experimental simulation, we have had the next results.1.In the case of the optical axes of the two cameras intersect or the case of imaging 3-dimensional object, a pixel of one image taken with one camera almost coincides with some pixel of the other image taken with the other camera. And hence in such portion spatial resolution is not improved satisfactorily.2.On the other hand, the utilization of multiple cameras various in their pixel apertures enables us to remove this non-uniform improvement problem, because in the different-aperture case, unlike the same-aperture case, a pixel of one camera taken with one camera never coincides with any pixel of another camera taken with another camera irrespective of the arrangement of multiple imagers.In this research, we show the advantage of utilization of multiple cameras various in their pixel apertures, but it is requires that investigation of robust registration algorithm even under severe aliasing effects and available in the different aperture case.
