Information synchronization device, information synchronization method, and information synchronization program

An information synchronization method of synchronizing, to a reference timestamp, data in which one or more labels for identifying respective one or more subjects on a video and one or more pieces of location information for identifying respective locations of the one or more subjects are respectively associated, the method comprising:

• receiving, by a computer, the data at each time;
• storing, by the computer, the received data into a buffer;
• and
• generating, by the computer, upon pieces of the location information at times before and after the reference timestamp being stored into the buffer for any of the labels, location information of the label at the reference timestamp by interpolation using the pieces of the location information.

A non-transitory computer readable medium storing one or more instructions causing a computer to operate as an information synchronization device configured to synchronize, to a reference timestamp, data in which one or more labels for identifying respective one or more subjects on a video and one or more pieces of location information for identifying respective locations of the one or more subjects are respectively associated, the one or more instructions causing the computer to execute:

• receiving, by the computer, the data at each time;
• storing, by the computer, the received data into a buffer;
• and
• generating, by the computer, upon pieces of the location information at times before and after the reference timestamp being stored into the buffer for any of the labels, location information of the label at the reference timestamp by interpolation using the pieces of the location information.
