Sensor delay time estimation device, sensor delay time estimation method and recording medium

A sensor delay time estimation method, comprising:

• acquiring a plurality of observables from a plurality of sensors, each of the plurality of sensors being different, and each of the plurality of sensors detecting and outputting a respective observable from among the plurality of observables;
• and
• estimating, based on the observables for a period of time, a time delay from detection to acquisition of observables other than one reference observable for the period of time,
• wherein the reference observable is output by a reference sensor of the plurality of sensors, the reference sensor having a minimum delay time from detection to acquisition of its respective observable with respect to other sensors from among the plurality of sensors.

A non-transitory recording medium that records a program that is executable by a computer to perform a sensor delay time estimation processing, the sensor delay time estimation processing comprising:

• acquiring a plurality of observables from a plurality of sensors, each of the plurality of sensors being different, and each of the plurality of sensors detecting and outputting a respective observable from among the plurality of observables;
• and
• estimating, based on the observables for a period of time, a time delay from detection to acquisition of observables other than one reference observable for the period of time,
• wherein the reference observable is output by a reference sensor of the plurality of sensors, the reference sensor having a minimum delay time from detection to acquisition of its respective observable with respect to other sensors from among the plurality of sensors.
