Method and system for obtaining full focal distance image without optical aberration

一种全焦距无像差图像摄取方法及系统

Abstract

The invention relates to a full-focus non-aberration image shooting method and system. With the method and system and based on the conditions and imaging principle of linear space, the lens in camera shooting apparatus can acquire degraded image data for images in camera; then, image partition can divide non-blend single object distance regions of single object distance according to the object distance, mix blend regions in a plurality of object distances, and moreover, perform full-focus non-aberration reconstruction, correction and overlapping into one plane for the non-blend single object distance regions and blend region belts; then, full visual field sharp digital images can be gained as well as object distance of all points in the visual field. Since the method and system utilize and realizes the full-focus non-aberration image shooting, the theoretic definition of the captured images can reach the level of complete consistence with that of plane images through optical system focusing, so that the overall images can provide full visual field and full-focus non-aberration sharp images and gain the maximum information volume.
本发明涉及一种全焦距无像差图像摄取方法及系统,利用该方法和系统依据线性空变的条件和成像原理,通过摄像装置的镜头获取被摄图像的模糊图像数据后,通过图像分区按物距划分出单一物距的非交融单一物距区域,混合多个物距的交融区域,并对非交融单一物距区域、交融区域带进行全焦距无像差重建、校正,并叠加到一个平面,得到全视野的清晰数字图像,并可得到视野内各点的物距。通过本发明,应用实现全焦距无像差拍摄,使被拍摄的图像理论上的清晰程度达到和在光学系统聚焦平面图像的清晰程度完全一致的水平,整个图像提供全视野,全焦距的无像差清晰图像,获得最大的信息量。
