| Outline of Final Research Achievements |
The research was divided into two themes. (1) Basic analysis to clarify the basic characteristics of ground-based terrestrial lasers. (2) Creation of high-precision topographical data and acquisition of high-precision position information using the QZSS. As an application experiment of (1), an experiment using a wave-dissipating concrete block model was carried out. As a result of examining the relationship between the wave-dissipating concrete block and the number of point clouds, the characteristics of the ground-based terrestrial laser and the problems during observation were clarified.
As an application of (1) and (2), I proposed a method to prevent the missing or accident damage caused by "haikai" of people with dementia patients. By fusing high-precision position information from satellite data including the QZSS and high-precision topographical data from laser measurement, it is possible to contribute to the search when a person with dementia patients disappears due to wandering.

レーザデータ、衛星データ、地形データなど空間情報工学分野における夫々の技術は単独で用いられることが多い。本研究は高精度な位置情報が取得できる「みちびき」データと、地上型レーザ計測によって得られる高精度地形情報データを融合することにより、空間情報技術の新しい応用分野について検討することにある。最初に、地上レーザの観測特性を把握するため、2種類のモデル実験（平面的な対象物の観測特性と立体構造物の三次元特性）を実施した。
これらの結果を踏まえ、近年、国内でも大きな問題となりつつある見当識障害者（認知症患者）の「はいかい」による行方不明や事故被害の防止に対して空間情報工学を利用する方法を提案した。
