Abstract
A scanning camera for capturing a set of oblique images along a curved scan path on an object plane within an area of interest, each image of the set of images associated with a viewing angle and a viewing direction relative to the object plane, the scanning camera comprising an image sensor; a lens; a scanning mirror; and a drive coupled to the scanning mirror; wherein the drive is operative to rotate the scanning mirror about a spin axis according to a spin angle; the spin axis is tilted relative to a camera optical axis; the scanning mirror is tilted relative to both the camera optical axis and the spin axis and positioned to reflect an imaging beam into the lens, a viewing angle and a viewing direction of the imaging beam relative to the object plane varying with the spin angle; the camera optical axis is tilted at an oblique angle relative to the object plane; the lens is positioned to focus the imaging beam onto the image sensor; and the image sensor is operative to capture each image by sampling the imaging beam at a corresponding value of the spin angle corresponding to the viewing angle and the viewing direction of the image.
