Abstract
A computer is configured to: specify the number of times of a time point when the target is detected at the same time point among time points by each set of two sensors among the three or more sensors by using whether the target is detected by each of the three or more sensors at each time point; generate information indicating connectivity regarding estimation accuracy of a relative positional relationship between sensors by using the number of times specified for each set of sensors and a variance of arrangement positions of the targets at the time points; generate information indicating a first relative positional relationship between two sensors having connectivity by using the information indicating connectivity; generates information indicating a second relative positional relationship between two sensors having no connectivity by using the information indicating connectivity and the information indicating the first relative positional relationship; and outputs the generated information.
