Title:
INFORMATION PROCESSING APPARATUS, CONTROL METHOD, PROGRAM, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/062782
Kind Code:
A1
Abstract:
This information processing apparatus has a predicted position acquisition means, an estimated position calculation means, a reliability calculation means, and a speed calculation means. The predicted position acquisition means acquires a predicted position of a ship. The estimated position calculation means calculates an estimated position of the ship obtained by updating the predicted position on the basis of a comparison of data based on output of an external sensor provided to the ship and map data. The reliability calculation means calculates the reliability of the comparison. The speed calculation means calculates the speed of the ship at a first processing time on the basis of the estimated position at the first processing time, the estimated position at a second processing time immediately before the first processing time, and a time constant that is set on the basis of at least the reliability.
