Estimating the Height of Sediment from Dog Trajectory and Ground Shape

Abstract

We aim to develop a method to measure the height of sedimentary sand from dog's moving trajectory and ground shape data. In sediment-related disasters, it is important to grasp the height of sedimentary sand for the search of victims. If we can visualize the search trajectory of rescue dog three-dimensionally, we can measure the sedimentary sand accumulated place and the depth of it comparing with the topographic map before the disaster. Therefore, we estimate the search trajectory of SAR dogs in three dimensions using the sensors, such as IMU and GNSS, which is mounted on dog. From the result of experiment, we can estimate the height of sedimentary sand from dog's running 3D trajectory.
