The distributed and coordinated information processing apparatus according to the present invention is distributed in a predetermined field to eliminate the need for a centralized server, which is a single failure point of the system, and to perform estimation and judgment processing stably even if there is a node failure or the like. Distributed and coordinated information processing apparatus, wherein information indicating the certainty of a set of hypotheses of the state of the surrounding environment based on the measurement detection means for measuring the surrounding environment using the sensor device and the measurement result of the surrounding environment And estimation means for generating estimation determination information, communication means for receiving estimation determination information generated by another distributed coordinated information processing apparatus in the field, and an adjacent for managing information of the other distributed coordinated information processing apparatus It has management means and fusion means for fusing the estimated judgment information generated by the own device and the estimated judgment information received from another distributed coordinated information processing apparatus.
