  • Patent number: 8218824
    Abstract: An orthographic projection creating unit creates an orthographic projection image from an optical image of an ground surface acquired by an optical camera, and a DSM generating unit generates a DSM from the orthographic projection image. A laser point group data generating unit generates three-dimensional point group data based on a laser measurement result of the ground surface by a laser measuring device. An object generating unit groups altitude data of the DSM and altitude data of the three-dimensional point group data for each of objects such as buildings. A synthesizing unit extracts the same objects from the grouped altitude data of the DSM and three-dimensional point group data, associates the objects with each other based on respective coordinate information thereof, and replaces altitude information of the optical image by high-accuracy altitude information of the three-dimensional point group data for each of the objects.

  • Patent number: 7233872
    Abstract: The error of a sensor in motion capture system is corrected. An acceleration sensor determines the direction of gravity (G1) in a still initial state. The direction G1 will never change always if a drift dose not occur. However, actually if an object to which an acceleration sensor is attached moves along a coordinate axis, the direction gradually changes due to a drift with time. According to the invention, after a given time has passed, the acceleration sensor is stopped to determine the direction of gravity. Referring to the data on this determination, the true direction of gravity to be judged is compared with the direction of gravity G1 influenced by the drift. The difference between them is assumed to be an error due to a drift, and the error is subtracted from the determined value to correct the error of the measurement value.

  • Patent number: 6972757
    Abstract: Disclosed is a pseudo 3-D space representation system capable of creating a cubic pseudo 3-D space with a plurality of 2-D images by simple operation. An operation display means displays plural images to a user who is requested to specify a same area on each of two or more images by using an area specifying means. A specified area associating means associates the specified area on one image with the specified area on the other image as one set or plural sets of common parts. An image transforming means transforms one or both images by matching the specified areas by affine transformation and an image display means displays both images as superposed on one the other.
