Title:
データ処理装置、データ処理方法およびデータ処理プログラム
Document Type and Number:
Japanese Patent JP7077044
Kind Code:
B2
Abstract:
Data processing is enabled by which by which three-dimensional point group data with fewer errors can be obtained based on measurement data acquired by a mobile body that moves in a measurement section. A data processing device (100) includes a trajectory calculating unit (112) configured to calculate a trajectory of a mobile body (27) that moves in a measurement section, based on measurement data acquired by the mobile body (27), a virtual level difference detecting unit (113) configured to detect a virtual level difference occurring in the trajectory, a trajectory smoothing unit (114) configured to smooth the trajectory in a section before and after the virtual level difference according to a magnitude of the virtual level difference, and a point group data generating unit (115) configured to generate synthetic point group data by synthesizing the smoothed trajectory and point group data included in the measurement data.
