  • Patent number: 11009348
    Abstract: The interior of a first measurement surface and the interior of a second measurement surface traveling together with a measuring vehicle are scanned to acquire first measurement coordinate points and second measurement coordinate points, respectively. A first comparison point cloud representing a comparison part on a surface of a structure is extracted from the first measurement coordinate points. A second comparison point cloud representing a comparison part on the surface of the structure is extracted from the second measurement coordinate points. A difference between the first comparison point cloud and the second comparison point cloud corresponding to measurement of a common comparison part on the surface of the structure is calculated. Error having time dependence included in the first measurement coordinate points and the second measurement coordinate points is calculated on the basis of the calculated difference. The measurement coordinate points are corrected on the basis of the calculated error.

  • Patent number: 11002552
    Abstract: A slope sample value at a sample point on a target route and a distance sample value from a reference point on the target route to the sample point are calculated based on three-dimensional position data of the target route. Undetermined elements contained in a model formula for the approximation formula representing relation between the slope sample value and the distance sample value are determined using an error evaluation formula for the model formula. The error evaluation formula contains a slope error evaluation component for evaluating a slope error between the slope sample value and a slope model value that is calculated using the model formula, and an altitude error evaluation component for evaluating an altitude error between an altitude model value that is obtained through integration of the slope model value and an altitude value that is obtained from the three-dimensional position data.

  • Patent number: 10740936
    Abstract: In a trolley-wire display device, a display reference point of point-group data is set for each point on a trolley wire having a height and a displacement measured based on a reference obtained from rails. First and second points on a track center line are used to calculate a first distance, and a third distance based on the first distance and a second distance. The first point corresponds to the display reference point. The second point corresponds to each point on the trolley wire. The first distance is a distance from the first point to each second point. The second distance is a distance from a positional start point to the first point. The third distance is a distance from the start point to each second point, and is used to create display data for displaying a height and a displacement of each point on the trolley wire.
