Abstract
A position measurement method includes an exterior orientation parameter correcting step Sfor correcting exterior orientation parameters calculated in a step S, based on difference between photographing timing of an image and obtaining timing of a photographing position and/or a photographing posture measured outside, a bundle-adjusting step Sfor simultaneously adjusting a bundle of the exterior orientation parameters of one or more images and three-dimensional coordinates of characteristic points, based on the exterior orientation parameters corrected by the step S, a three-dimensional coordinate calculating step Sfor calculating three-dimensional coordinates of characteristic points subsequently detected in an area in which the density of the characteristic points is decreased, based on the exterior orientation parameters adjusted bundle thereof, and a repeating step for repeating processing from the steps Sto Suntil the image becomes a final image.
