Title: Device for estimating alignment error of sensor
Inventor: KIMOTO EIJI
IPC: G01C3/06
Filed: 1995-03-30
Abstract: PURPOSE: To calculate alignment error without receiving any influence of noises included in the observation position by obtaining a solution for the state formula while setting the alignment error of a sensor as a state variable when a plurality of objective positions are observed by using a plurality of sensors and estimating the alignment error. CONSTITUTION: An observation matrix generator 5 calculates the target observation matrix from the target observation positions of first and second observation devices 2 and 4. A device 6 for evaluating estimated values calculates the covariance matrix of the estimated value of alignment error based on the observation matrix. A calculator 7 for estimated value calculates the estimated value 8 of a second sensor 3 against a first sensor 1 based on the observation matrix and the covariance matrix of the estimated value for alignment error. Thus, since the alignment error is estimated by assuming a state formula using the target observation position in which the value 8 is set as a state variable, any influence of observation noises included in the observation error and observation position depending on the objective position is hardly given.
