Analysis apparatus, analysis method, and storage medium

An analysis method performed by a computer, the method comprising:

• acquiring a plurality of pieces of analysis target data collected at a plurality of edges;
• determining first analysis target data satisfying a first condition from among the plurality of pieces of analysis target data;
• specifying a first detection position indicating a position at which each piece of the determined first analysis target data is detected at the plurality of edges and a first detection time indicating a time when each piece of the determined first analysis target data is detected at the plurality of edges by referring to a storage that stores meta information corresponding to the plurality of pieces of analysis target data;
• acquiring a feature amount corresponding to each piece of the first analysis target data from the plurality of edges;
• calculating a correlation coefficient of the feature amount between respective pieces of analysis target data included in the first analysis target data;
• specifying a first range of the first detection position and a second range of the first detection time of the analysis target data for which the calculated correlation coefficient satisfies a predetermined relationship, from among the first analysis target data;
• determining second analysis target data which satisfies a second condition from among the plurality of pieces of analysis target data;
• specifying a second detection position and a second detection time corresponding to the determined second analysis target data by referring to the storage;
• determining whether specific analysis target data in which the specified second detection position is included in the first range and the specified second detection time corresponds to the second range is included in the second analysis target data;
• and
• acquiring any one piece of the specific analysis target data from the plurality of edges when it is determined that the specific analysis target data is included.

A non-transitory computer-readable storage medium storing a program that causes a computer to execute a process, the process comprising:

• acquiring a plurality of pieces of analysis target data collected at a plurality of edges;
• determining first analysis target data satisfying a first condition from among the plurality of pieces of analysis target data;
• specifying a first detection position indicating a position at which each piece of the determined first analysis target data is detected at the plurality of edges and a first detection time indicating a time when each piece of the determined first analysis target data is detected at the plurality of edges by referring to a storage that stores meta information corresponding to the plurality of pieces of analysis target data;
• acquiring a feature amount corresponding to each piece of the first analysis target data from the plurality of edges;
• calculating a correlation coefficient of the feature amount between respective pieces of analysis target data included in the first analysis target data;
• specifying a first range of the first detection position and a second range of the first detection time of the analysis target data for which the calculated correlation coefficient satisfies a predetermined relationship, from among the first analysis target data;
• determining second analysis target data which satisfies a second condition from among the plurality of pieces of analysis target data;
• specifying a second detection position and a second detection time corresponding to the determined second analysis target data by referring to the storage;
• determining whether specific analysis target data in which the specified second detection position is included in the first range and the specified second detection time corresponds to the second range is included in the second analysis target data;
• and
• acquiring any one piece of the specific analysis target data from the plurality of edges when it is determined that the specific analysis target data is included.
