We proposed a new topography measuring technique of a dam reservoir by combining UAV and compact wireless ultrasonic sounder. However, problems remained in terms of 1) communication distance limitation, 2) altitude setting during automatic navigation, and 3) measurement accuracy evaluation with RTK-GNSS and Narrow multi-beam sonar. Therefore, in this research, after improving the equipment and application, after conducting basic experiments on the measurement accuracy in the swimming pool, the field measurement was performed in the Ikeda Dam to comprehensively evaluate the practicability.
As a result, it was confirmed that the proposed measurement method has sufficient performance in practice under the measurement conditions implemented in this study.
