  • Patent number: 7023468
    Abstract: The photo survey service system of the invention comprises an image information receiving means 12 for receiving image information from customer's terminal equipment 8 via a telecommunication circuit network 10, which image information is obtained by taking photographs of an area 4 under survey having a plurality of stations 2-1, 2-2, . . . 2-n from a plurality of points using a digital camera 6 at a fixed focal length, an analysis processing means 14 which uses computation processing to calculate a three-dimensional vector relation of each station from the received image information on the basis of a difference in parallax between both images of adjacent photographing points, and an analytical result transmitting means 16 for transmitting information on the calculated three-dimensional vector relation of each station to the customer's terminal equipment 8 via the telecommunication circuit network 10.
