Outline of Final Research Achievements

In this study, we developed a methodology that integrates an inexpensive, extremely compact, and lightweight multi-frequency and multi-system GNSS receiver with RTK positioning technology and drone technology, all of which have recently been commercialized. This integration aims to enhance the accuracy of drone location information and the incidental location information of aerial photographs, thereby improving the alignment of photographs with maps. Specifically, we developed and evaluated the ACP method, which adds high-precision location information to select portions of multiple photos to create a photo map. Our findings show that this method improves accuracy by a factor of 5-10 horizontally and 100 vertically compared to cases where the ACP method is not used. Additionally, we applied and evaluated the accuracy of the CLAS positioning technology using the Quasi-Zenith Satellite MICHIBIKI.

Academic Significance and Societal Importance of the Research Achievements

本研究を達成することにより、一般的に利用されている価格帯のドローンでは到達することが難しかった高精度の写真地図作成が可能になる。また、はるかに高価な価格帯の一部のドローンに要求されている精度を、空間的により広い領域で実現することが可能になる。また、独自技術である「UAV斜め写真ブラウザ」の高精度化も同時に行うことができ、迅速・簡便な写真と地図の統合を高精度に行うことが可能になる。
