Abstract:
The aerial photograph image pickup method comprises a first step of acquiring still images along an outward route and a return route respectively, a second step of preparing a stereo-image with regard to three images adjacent to each other in advancing direction, and of preparing another stereo-image by relative orientation on one more set of adjacent images and of preparing two sets of stereo-images, a third step of connecting two sets of stereo-images by using feature points extracted from a portion of an image common to the two sets of stereo-images, a step of connecting all stereo-images in the outward route direction and in the return route direction according to images acquired in the first step by repeating the second and third steps, and a step of selecting common tie points from the images adjacent to each other in the adjacent course and connecting the adjacent stereo-images in the course.
Abstract:
A spectral image sensor device comprises a first optical system 47 and 48 including an objective lens, a luminous fluxes selecting member 55 for allowing a part of the luminous fluxes to pass via the first optical system selectively, an optical member 58 where the luminous fluxes selecting member is disposed so as to be at focal position on an object side or approximately at focal position on an object side, and an interference membrane is formed, and wavelength range of the luminous fluxes for passing through the luminous fluxes selecting member is selected, depending on position of the luminous fluxes selecting member, a second optical system 49 for guiding the luminous fluxes toward the optical member, and an image sensor 52 for receiving a light in wavelength range as selected by the optical member.
