| 摘要 |
Disclosed is an apparatus comprising a digital optical recording unit used for wide-angle recording of an image of a person, a creature, or an object whose spatial alignment and typical image-related characteristics are essentially defined, and a storage device for electronically storing the image. The aim of the invention is to create effective two-dimensional rectification in said apparatus. Said aim is achieved by means of a detection unit that two-dimensionally detects positions of the typical image-related characteristics of the recorded object relative to each other, a reference storage device containing positions of the typical image-related characteristics relative to each other, said positions corresponding to a standard arrangement, and a rectifying unit. Said rectifying unit is configured so as to read out the image stored in the storage device and rectify the stored image in accordance with a comparison between the relative positions of typical image-related characteristics of the recorded object in the detection unit and the relative positions of the typical image-related characteristics in the reference storage device, said positions corresponding to the standard arrangement. Also disclosed is a method for rectifying images recorded at a wide angle. |
