Information processing device, measurement device and control method
A server device stores on a storage unit an advanced map database which includes feature information associated with a feature. The server device receives, from vehicle mounted devices equipped with external sensors which measure features, difference information indicative of a difference between feature information and the actual feature corresponding to the feature information. In accordance with the degree of reliability which is calculated based on a plurality of the difference information, the server device sends to the vehicle mounted device a raw data request signal for requesting the transmission of raw data which is measurement data of the actual feature.
1. A terminal device mounted on a moving body comprising:
a measurement unit configured to measure a position of an object existing in a vicinity of the moving body;
a storage unit configured to store measured data generated by the measurement unit;
a receiving unit configured to receive map information from an external device,
the external device including a storage unit configured to store feature information associated with a feature,
the map information including information on a request to transmit information associated with the feature;
a transmitting unit configured to transmit the measured data stored in the storage unit to the external device after a distance between the position of the moving body and a position specified by the request is equal to or smaller than a predetermined distance.
2. The terminal device according to claim 1 , wherein the information on the request to transmit information associated with the feature is information indicating that a degree of reliability of the feature is unknown.
3. The terminal device according to claim 1 , wherein the information on the request to transmit information associated with the feature is information indicating:
the position of the feature to be measured to generate the measurement data; or
a measurement position to measure the feature.
4. A control method executed by a measurement device mounted on a moving body, the control method including:
measuring a position of an object existing in a vicinity of the moving body;
storing measured data;
receiving map information, from an external device,
the external device including a storage unit configured to store feature information associated with a feature,
the map information including information on a request to transmit information associated with the feature; and
transmitting the measured data stored in the storage unit to the external device after a distance between the position of the moving body and a position specified by the request is equal to or smaller than a predetermined distance.
