Abstract:
1. A method of obtaining three-dimensional (3D) surface data of an object scene, the method comprising: positioning a 3D imaging device so that a measurement field of view includes a portion of a directional view of an object scene and to acquire 3D data for the measurement field of view at a start of a first scan segment; translating the 3D imaging device while maintaining the directional view of the object scene so that the measurement field of view translates across a remainder of the directional view of the object scene during the first scan segment and the 3D imaging device acquires 3D data for the translated measurement field of view that are registered with the 3D data for the start of the first scan segment, the 3D data acquired during the first scan segment defining a backbone 3D data set; positioning the 3D imaging device so that the measurement field of view includes a portion of the directional view of the object scene for which 3D data were previously acquired during the first scan segment so that the 3D imaging device acquires 3D data for the measurement field of view that overlap a portion of the backbone 3D data set; joining the 3D data that overlap the portion of the backbone 3D data set to the backbone 3D data set for a start of a second scan segment; and maneuvering the 3D imaging device while continuing to acquire 3D data during the second scan segment so that the measurement field of view includes a portion of an orthogonal directional view of the object scene so that the 3D data for the measurement field of view that are acquired during the maneuvering of the 3D imaging device are registered to the backbone 3D data set.
