Determination apparatus, determination system, determination method, and recording medium

A determination system comprising:

• a detector that outputs data in time series, in accordance with a result of detection of a detection target;
• and
• a determination apparatus which comprises:
• a data obtaining unit that obtains the data outputted by the detector;
• a data correction unit that compares reference data indicative of data to be outputted by the detector when the detection target passed through a specific area with the data obtained by the data obtaining unit, and corrects the data obtained by the data obtaining unit so that a data length of the data is equal to a data length of the reference data;
• a similarity determination unit that determines a similarity between the data corrected by the data correction unit and the reference data;
• and
• a determination unit that determines whether the detection target passed through the specific area or not based on a result of the determination by the similarity determination unit.

A determination method comprising:

• obtaining data from a detector that outputs data in time series, in accordance with a result of detection of a detection target;
• comparing reference data indicative of data to be outputted by the detector when the detection target passed through a specific area with the data obtained from the detector;
• correcting the obtained data so that a data length of the data is equal to a data length of the reference data based on a result of the comparison;
• determining a similarity between the data obtained by the correction and the reference data;
• and
• determining whether the detection target passed through the specific area or not based on a result of the determination.

A recording medium storing a computer program, wherein the computer program comprising:

• causing a computer to obtain data from a detector that outputs data in time series, in accordance with a result of detection of a detection target;
• causing the computer to compare reference data indicative of data to be outputted by the detector when the detection target passed through a specific area with the data obtained from the detector;
• causing the computer to correct the obtained data so that a data length of the data is equal to a data length of the reference data based on a result of the comparison;
• causing the computer to determine a similarity between the data obtained by the correction and the reference data;
• and
• causing the computer to determine whether the detection target passed through the specific area or not based on a result of the determination.
