METHOD FOR PRODUCING AN IMAGE OF THE SURFACE OF THE EARTH FROM A MOVING CARRIER AND A DEVICE FOR IMPLEMENTING SAME

摘要

The method and a device for obtaining the Earth's image from a moving carrier are provided and relate to remote sensing of the Earth, specifically, to aerial photography, and can be used for photogrammetry, monitoring of vast areas and extended objects, large-scale mapping surveys and engineering design and surveys. The method provides Earth photographing at an angle to the vertical, which gradually increases toward the ends of the frame's longer side oriented transversally to the flight direction. During the formation of subframes making the frame of central projection, all photo sensors are exposed simultaneously, and the frame's bandwidth to length ratio is maintained at the 1 : 5...100 range. The device comprises photo sensors fixed in a holding fixture in such a way that, their optic axes projections onto a vertical plane are at an angle to the vertical, said angle unidirectionally varies from one photo sensor to another by the amount not exceeding the projection of the photo sensor view angle to said plane. Projections of said photo sensors' optic axes to another vertical plane, perpendicular to the first one form an angle that is no larger than 50 % of the projection of the photo sensor view angle onto this plane, thus ensuring high performance of the survey with concurrent improvement of the quality of the output image.
