Title:
DATA ANALYSIS DEVICE, SEARCH SYSTEM, DATA ANALYSIS METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2024/048056
Kind Code:
A1
Abstract:
An objective of the present disclosure is to grasp the accurate state of a buried object or a hollow and identify the position thereof without limitation on location. Accordingly, a data analysis device 9 performs image data matching between first image data A1, which pertains to a first specified surface associated with radar search data A2 related to the first specified surface, and second image data B1, which pertains to a second specified surface adjacent to the first specified surface and associated with radar search data B2 related to the second specified surface, and composites the two pieces of radar search data to generate composite search data AB2. The data analysis device 9 performs image data matching between each of third image data pertaining to a specific surface 51 and fourth image data pertaining to a specific surface 52, the third image data and the fourth image data being acquired from a ground control-point measurement device 6, and specific image data that is at least one of the first image data or the second image data and includes the specific surface 51 and the specific surface 52, and performs calibration of an absolute position pertaining to the composite search data AB2 on the basis of individual absolute positions associated with the third image data and the fourth image data.
