摘要： It is an object to improve the accuracy of a house change judgment based on images and the like acquired by an airplane. A terrain altitude is subtracted from an attitude value of a digital surface model (DSM) acquired from an airplane or the like to generate a normalized DSM (NDSM). A judgment target region is segmented into a plurality of regions of elevated part for each elevated part with a size corresponding to a house appearing on the NDSM. An outline of the house is extracted from each region of elevated part and a house object containing three-dimensional information on the house is defined by the outline and NDSM data within the outline. The house objects acquired at two different time points, respectively, are compared to detect a variation between the two different time points, and a judgment as to a house change is made based on the variation.

摘要： It is aimed to enable analyzing vegetation growth conditions at multiple times of a year accurately using radar images obtainable from a flying body such as artificial satellites, etc. A plurality of radar images of a ground surface of a same target area, which have been taken at multiple times of a year by a radar device mounted on a flying body, are acquired. The acquired plurality of radar images is stored in a map database. While using as a criterion image a radar image of the plurality of radar images stored in the map database, taken at a predetermined time in the multiple times of a year, other radar images than the criterion image of the plurality of radar images, taken at other times than the predetermined time in the multiple times of a year, are aligned with the criterion image, respectively. Then, backscatter coefficients of specified areas in the plurality of radar images are extracted. Based on a backscatter coefficient of a specified area in the criterion image of the plurality of radar images stored in the map database, backscatter coefficients of other radar images than the criterion image of the plurality of radar images are calibrated. And, based on a correlation between backscatter coefficients of radar images and growth values of vegetation shown in the radar images, growth values of vegetation shown in other radar images than the criterion image of the plurality of radar images, whose backscatter coefficients have been calibrated in the calibrating step, are calculated using the calibrated backscatter coefficients.

摘要： Measurement of 3D displacement based on successively captured images of an object becomes difficult to be performed due to a load imposed on an operator along with an increase of the number of target portions defined on the object and that of time steps for displacement measurement. A device for displacement measurement executes stereo measurement relative to a stereo image to generate 3D shape information and orthographically projected image of an object for each time, and tracks the 2D image of the target portion through pattern matching between orthographically projected images at successive times to obtain a 2D displacement vector. The device for displacement measurement converts the start point and the end point of the 2D displacement vector into 3D coordinates, using the 3D shape information, to obtain a 3D displacement vector.
