multiple scan locations of multiple rooms. In addition to the data types described above, you can
add labels, text, measurements, and even blood spatter analyses to a scene file.
One of the advantages of scene files is the ability to add information and analyses to the scene
without changing any of the data – preserving the integrity of the original captured data files. In
addition, scene files use the data files without creating new copies of them – enabling the
creation of more than one scene file from the same set of data – perhaps by two different users.
3.2.1
Creating Scene Files from a Scan Session
Scanning a scene with the DeltaSphere-3000 can produce a large number of files. SceneVision
provides a standard organization scheme so that all files are produced with a logical naming
scheme and are stored with a logical file organization. The general organization is:
A folder for the entire scene
A subfolder for each scan containing the range file for that scan
In each scan’s subfolder, another subfolder for all photos associated with that scan.
Figure 17 illustrates a scene composed of three scans (lr_body, lr_doorway, lr_reference) with
an additional folder for
freehand
photos. This is discussed further in Section 4.

SceneVision-3D Uses
SceneVision provides many different functions for a variety of uses – depending on your
particular task and the goals for your work.
3.3.1
Acquiring Data
SceneVision controls the DeltaSphere-3000 scanner – both for laser scanning and image
acquisition with its (optional) digital camera. All instrument control – from aiming and setting
scan parameters to file naming – is through SceneVision. Sections 4 and 6 describe
SceneVision’s scan controls.
