Crime, Accident, and Fire Scenes
the Focus3D Laser Scanner and SceneVision-3D Software do for you?

At the scene - capture the scene in 3D and color with the Focus3D
Measurements of an entire crime or accident scene - tens of millions of measurements -
automatically. The Focus3D does a complete 360° scan in about 2 minutes and measures everything it can see. It uses only the space needed by a
standard photographer's tripod. Scan from multiple locations and combine the
scans to capture everything.
- automatically take high-resolution images, blanketing a scene - in less
than 2 minutes.
These pictures are automatically combined with the measurements
to create color models. Take additional close-up photos with a calibrated
camera to add extra detail to key areas of the scene with high-resolution
On your laptop - view, measure, diagram, reconstruct, present with
the distance between any two points - just point and click on your
laptop - or measure the perpendicular distance from any point to the floor
or to a wall. Make these measurements on your pc at the scene, or back in your office, from the data captured. Minimize time
and effort at the scene. Make additional measurements, as needed, months or
years later - long after the scene has been disturbed.
- Combine multiple scans of
a scene into a single 3D computer graphics model
quickly and easily. Do 3D Crime Scene Reconstruction in minutes.
the model from any vantage point. Look at the scene directly from
above, from outside the window, from inside a closet.
- Create outline
diagrams of the scene - with accurate measurements - quickly and easily. Use
the Wall Wizard to quickly and easily produce all the edges of a
room, complete with measurements. Display the 3D model with the
measurement lines - or just show the lines alone as a simple diagram. Add
accurate, measured outlines of doors, windows, furniture - any objects in
the scene - directly from the data captured with the DeltaSphere scanner.
- Analyze blood
- Add high-resolution, photo
'hot spots' of critical data.
- Create specific Viewpoints
corresponding to the location of an officer or suspect. Show the location of
the viewpoint in the scene - and demonstrate precisely what was visible from

display the location of the camera for any photo taken with the DeltaSphere
- Create a 'walk through' of
the scene for automatic replay.
- Present the 3D model of
the scene to colleagues or in court. Show the scene from any viewpoint, at
to the left is a scan of one room in a staged murder scene. It is a
360° scan with approximately 28 million measurements - begun with a
single touch. It takes the Focus3D approximately 4 minutes to
produce this scan. Scans with approximately 10 million points can take
less than a minute.
| The data that appears
curved, like the edge of the floor or the top of the window, results
from displaying this 3D data as a 2D projection. These are not
distortions in the data. When displayed in 3D these edges display

image shows a close-up of the data shown in the image above. As soon as this data is
transferred to SceneVision-3D you can measure the distance between any two points.
If you can see two points in a scan you can find the
distance between them. SceneVision includes many more advanced
measurement functions as well - including the Wall Wizard for find all
the edges of rooms, angle measurements, and perpendicular measurements..
the scanned data, SceneVision-3D automatically creates a 3D computer graphics model of the entire
scene, or of objects in the scene. This image shows a 'wire frame' model -
surfaces created by connecting the points from the scanner. This
model can be viewed from any viewpoint in SceneVision.

above. This is not just an image - it's a full, 3D model. SceneVision includes tools for
creating these solid, full color, 3D computer graphics models.

shows a simple, accurate outline of the murder scene above. It was
created in a matter of minutes using SceneVision-3D's measurement
functions. Even data not captured, like parts of the ceiling or corners
hidden by furniture, can be calculated by simply extending surfaces to
find the missing edges. SceneVision-3D's Wall Wizard produces
these measurements and drawings quickly and easily.
SceneVision provides functions and display for
visualizing close up images of blood spatter in 3D, and projecting their
trajectories from calculations made by the specialist, or within the
program. The image on the left shows simulated blood spatter on a wall.
Three spatter drops were measured and the purple lines represent their
calculated trajectories in 3D. The blue line represents a line from the
source drawn perpendicular to the wall.
In SceneVision, you can attach a close-up photo to any
point in a scene. In the image to the left, a photo of a weapon has been
added to the scene and will appear whenever the user double clicks on
the appropriate annotation.
Once the model is created, it can be viewed from any viewpoint in real time on
any standard PC. These two images below show the same scene from two other
viewpoints. (The black parts of the images are areas not scanned - either
outside the room or underneath the tripod. The 'floating' lines in the right
image are parts of the window seen in the left image.)
