SENSOR INFORMATION COMPLEMENTING SYSTEM AND SENSOR INFORMATION COMPLEMENTING METHOD
First Claim
1. A sensor information complementing system, comprising:
- a plurality of sensors;
sensor control means for acquiring sensor information from the plurality of sensors;
storage means for storing sensor information regularly acquired from the plurality of sensors;
relevant sensor selecting means for selecting, for each of the sensors, another sensor whose sensor information is correlated to sensor information of the sensor, by using stored sensor information;
sensor information estimating means for estimating information of a target sensor by acquiring sensor information of another sensor correlated to the target sensor; and
sensor information acquiring means for, when acquisition of sensor information of a sensor is requested, acquiring sensor information from the requested sensor if the sensor is available, and acquiring sensor information of the requested sensor estimated by the sensor information estimating means if the sensor is unavailable.

Abstract
Sensor information is regularly acquired from a plurality of sensors and stored. For each of the sensors, other sensors whose information is correlated are selected. When sensor information of a sensor is requested from an application program or the like, while if the requested sensor is available the sensor information is acquired directly from the sensor, if the requested sensor is unavailable the sensor information of sensors relevant to the sensor is acquired and the sensor information of the requested sensor is estimated. As a result, in a system comprising a plurality of sensors, sensor information of an unavailable sensor will be estimated in a short period of time.

6. A sensor information complementing method for estimating, in a system having a plurality of sensors, sensor information of a specific sensor on the basis of sensor information of other sensors when the sensor information is unavailable from the specific sensor, the method comprising the steps of:
-
regularly acquiring sensor information from the plurality of sensors and storing the sensor information; selecting, for each of the sensors, another sensor whose sensor information is correlated to sensor information of the sensor, by using stored sensor information; and estimating, when acquisition of sensor information of a sensor is requested, sensor information of that sensor by acquiring sensor information of another sensor correlated to that sensor. - View Dependent Claims (7)
