Information processing device, information processing method, and program

Abstract

This technology extracts feature points from subjects photographed through a fence, achieving high flexibility without requiring massive computing resources. [Solution] The information processing device includes a calculation unit that extracts feature point clouds from images taken of a fence having a mesh-like periodic pattern and an object behind the fence, treats the feature point clouds as two-dimensional sparse data, and performs autocorrelation on the data to identify point clouds that appear at a specific period from the feature point clouds.

Claims

1. A calculation unit extracts feature point clouds from images of a fence having a mesh-like periodic pattern and objects behind the fence, treats the feature point clouds as two-dimensional sparse data, and performs autocorrelation on the data to identify point clouds that appear at a specific period from the feature point clouds. An information processing device equipped with the following features.

2. The calculation unit extracts a plurality of peak points in the image obtained by the autocorrelation, obtains a vector that has a direction from the first peak point to the second peak point adjacent to the first peak point, and whose length is the distance between the first peak point and the second peak point, The point cloud is identified based on the set of points that overlap with other points when one of the multiple points included in the feature point cloud is moved in the direction of the vector by an integer multiple of the length of the vector. The information processing apparatus according to claim 1.

3. The calculation unit extracts the feature points of the object by removing the point cloud from the feature point cloud. The information processing apparatus according to claim 1.

4. The aforementioned fence is a fence for a rack on which information and communication equipment is mounted, and the aforementioned object is information and communication equipment. The information processing apparatus according to claim 1.

5. An information processing method performed by an information processing device, A feature point cloud is extracted from images of a fence with a mesh-like periodic pattern and an object behind the fence. This feature point cloud is treated as two-dimensional sparse data, and autocorrelation is performed on the data to identify point clouds that appear at a specific period from the feature point cloud. Information processing methods.

6. A program for causing a computer to function as an arithmetic unit in an information processing device described in any one of claims 1 to 4.
