Sampling position-fixing system
First Claim
Patent Images
1. A sampling position-fixing system comprising:
- an inputting unit that inputs image data as an analyzing target;
an image correlating unit that correlates the image data with map data;
a unit that extracts feature vectors of the image data correlated with the map data by the image correlating unit;
a classification processing unit that performs clustering for the extracted feature vectors on a feature space to obtain a plurality of clusters of feature vectors;
a center area setting unit that extracts feature vectors that locate in vicinity of centers of respective said plurality of clusters on the feature space and maps the extracted feature vectors on an image space to derive cluster center expressing areas respectively corresponding to the centers of the clusters;
a representative point extracting unit that extracts representative points respectively representing said plurality of clusters from a plurality of candidate points composing said cluster center expressing areas by selecting one candidate point from the candidate points composing the cluster center expressing areas contained in areas corresponding to each of the clusters as a representative point, on the basis of distances from other representative points; and
an outputting unit that outputs the extracted representative points as sampling positions.

Abstract
In the case of collecting samples, it is difficult to select a representative point of a target area. Thus, the samples are collected from certain positions, resulting in generation of variations of data. The target area is specified on an image to extract features from the target area. Further, clustering is performed for the features on a feature space to obtain representative features, and the obtained representative features are extracted as sampling points.
