Title:
SYSTEM, METHOD, AND PROGRAM FOR ESTIMATING POSITION OR CHANGE IN POSITION OF RIGHT-ANGLED STRUCTURE OF STRUCTURE, AND STORAGE MEDIUM STORING PROGRAM
Document Type and Number:
WIPO Patent Application WO/2019/098280
Kind Code:
A1
Abstract:
A system, method, and program that, for a structure that has a right-angled structure in which a first section that has a horizontal-direction surface or a surface that is inclined at exactly a prescribed angle from the horizontal direction and a second section that has a vertical-direction surface or a surface that is inclined exactly the prescribed angle from the vertical direction form orthogonal surfaces, make it possible to find the position or the change in position of the first section in a first direction that is orthogonal to the horizontal-direction surface or the surface that is inclined exactly the prescribed angle from the horizontal direction, e.g., the height or the change in height of the floating roof of a floating roof tank; and a storage medium that stores the program. The system, method, and program are for estimating the position or the change in position of the right-angled structure of the structure using an SAR intensity image of the structure, without the need to frequently collect a large quantity of high-resolution SAR images, and without the need to create 3D data.
