Calculating the position of a measurement target using multiple measuring devices

A server, comprising:

• a communication circuit configured to communicate with a first electronic device and a second electronic device;
• a processor configured to execute one or more instructions;
• and
• a memory configured to store the one or more instructions,
• wherein the communication circuit is configured to
• transmit a measurement request for a measurement target to a plurality of roadside base stations, the plurality of roadside base stations including at least three roadside base stations,
• receive measurement information from the plurality of roadside base stations, the measurement information indicating respective distances between each of the at least three roadside base stations and the measurement target, the measurement information including
• first measurement information including a result of measuring the measurement target by the first electronic device, the first electronic device at a first roadside base station of the at least three roadside base stations, and
• second measurement information including a result of measuring the measurement target by the second electronic device, the second electronic device at a second roadside base station of the at least three roadside base stations,
• wherein the processor is configured to execute the one or more instructions to
• calculate a position of the measurement target based on the first measurement information, the second measurement information, a position of the first electronic device, and a position of the second electronic device, the calculating based on a determination that the first roadside base station and the second roadside base station are a closest two roadside base stations to the measurement target among the plurality of roadside base stations, based on the measurement information received from the plurality of roadside base stations, and
• transmit driving information to one or more vehicles based on the calculated position of the measurement target to cause the one or more vehicles to adjust navigation of the one or more vehicles.

A system for calculating a position of a measurement target, the system comprising:

• a first electronic device at a first roadside base station of at least three roadside base stations, the first electronic device configured to
• measure a first distance, which is a distance between the first electronic device and the measurement target, and a first relative speed, which is a relative speed of the measurement target with respect to the first electronic device, and
• generate first measurement information including the first distance and the first relative speed;
• a second electronic device at a second roadside base station of the at least three roadside base stations, the second electronic device configured to
• measure a second distance, which is a distance between the second electronic device and the measurement target, and a second relative speed, which is a relative speed of the measurement target with respect to the second electronic device, and
• generate second measurement information including the second distance and the second relative speed;
• and
• a server configured to
• receive measurement information from a plurality of roadside base stations, the plurality of roadside base stations including the at least three roadside base stations, the measurement information indicating respective distances between each of the at least three roadside base stations and the measurement target, the measurement information including the first measurement information and the second measurement information,
• calculate the position of the measurement target and an absolute speed of the measurement target based on the first measurement information, the second measurement information, a position of the first electronic device, and a position of the second electronic device, the calculating based on a determination that the first roadside base station and the second roadside base station are a closest two roadside base stations to the measurement target among the plurality of roadside base stations, based on the measurement information received from the plurality of roadside base stations, and
• transmit driving information to one or more vehicles based on the calculated position of the measurement target to cause the one or more vehicles to adjust navigation of the one or more vehicles.
