Abstract
Abstract Photogrammetric methods are provided for the preparation of anaglyphic orthophotographs in which first and second diapositives having overlapping image areas of at least 55 to 65 percent are positioned above a vertically adjustable plane in spaced apart relation and in a planar attitude corresponding to the attitude of the focal plane of the camera when taken. First and second coloured high intensity light beams are projected through the first and second diapositives, respectively, to generate first and second coloured image beams. The first and second image beams representing an image corresponding to a selected object distance from the focal plane of the camera are focused to intersect at a point. The vertically adjustable plane is then adjusted so that said point of intersection lies in the plane. Colour photosensitive material is then positioned in the vertically adjustable plane and the images from the first and second image beams are exposed thereon. The exposed material is thereafter developed to provide an anaglyphic orthophotograph wherein the first and second colour images are separated by a distance proportional to their relative vertical object displacement. Methods for preparing colour and infrared orthophotographs are disclosed in which said steps are modified by using colour negatives and or colour diapositives. Further, the photosensitive material is exposed in segments while the vertically adjustable plane is continuously adjusted during exposure to provide superposition of selected images, and printing one of said images.
