| Outline of Final Research Achievements |
This research establishes a technique for improving the positioning accuracy of inertial surveying. The study used an inertial measurement unit (IMU) with a camera, and the camera’s position as it took photographs was calculated using photogrammetry. This data was used as input for the external information on the Kalman filter to correct inertial surveying errors.
Our results are as follows. (1) An inertial surveying method using camera position information was developed. (2) A technique for adding a scale to the coordinates acquired using the structure from motion (SfM) method was developed. (3) A hybrid surveying method consisting of SfM and an IMU was proposed, and its effectiveness was proven. (4) A new application example of the surveying method created by combining photogrammetry with inertial surveying was demonstrated.
