Patent ID: 10308374

Abstract:
A stereo distance measuring apparatus includes a first optical camera and a second optical camera, a position-posture calculator, an image corrector, and a stereo distance measuring unit. The first and second optical cameras are provided in an elastic structure part of an aircraft and separated from each other. The first and second optical cameras constitute a stereo camera. The position-posture calculator calculates, on the basis of a displacement amount of the elastic structure part, first and second position-posture information regarding positions and postures of the first and second optical cameras, respectively. The image corrector generates first and second corrected images by correcting, on the basis of the first and second position-posture information, positions and orientations of images taken by the first and second optical cameras, respectively. The stereo distance measuring unit calculates a distance to a photographing target, on the basis of the first and second corrected images.
