概要

論文の詳細を見る
High-accuracy 3-dimensional measurement system was developed to acquire the Information of topography and plant status in the farm land. Laser scanners and a hyperspectral camera were used as sensors. The method which synchronizes between a GPS time and sensors were developed using low-cost synchronization circuit board. As a result, 1pps signal and 75Hz signal provided for laser scanners were synchronized with accuracy of 0.2μs and the laser scanner and 75Hz signal were synchronized with accuracy of 0.12ms.
