PURPOSE:To provide a direction measuring device which can calibrate the error accompanying the direction measurement of a target by calibrating the error accompanying the direction measurement of a target by estimating, from the relation between a standard light emitter and a sensor, the structural deformation quantity on a structural model for a soft structure on which the sensor is mounted, and further display the estimation result and the calibrated position measurement of the target. CONSTITUTION:A direction measuring device is provided with a standard light emitter 2 and a sensor 3 to estimate the structural deformation quantity on a structural model for a soft structure part on which the sensor 3 is mounted on the basis of the deviation between the direction data of the standard light emitter 2 detected by the sensor 3 and a predetermined standard direction data to the standard light emitter 3. On the basis of the structural deformation quantity, the error accompanying the direction measurement of a target is calibrated. The device is further provided with a display means 5. |
