 | Capture the location of all points in a crime or accident
scene without contaminating the scene. The DeltaSphere-3000 does a complete
360° scan in 12 minutes. It uses only the space needed by a tripod and
laptop computer. |
| Capture color in just a few minutes more. |
| Measure the distance between any two points - with the
cursor on your laptop. Take measurements back in your office from the data
captured. Minimize time and effort at the scene. |
| Create a computer graphics, 3D, interactive model of the
scene - from the actual scanned data. |
| View the model from any vantage point.
Look at the scene directly from above, from outside the window, from inside
a closet. |
| Present the 3D model of the scene to colleagues or in
court. Show the scene from any viewpoint, at any scale. |

The image below is a scan of a room. The operator selected a
vertical field of view of 65° and a
horizontal field of view of 360°. Each vertical 'scan line' contains approximately 860
points, and there
are 4800 of these scan lines, resulting in approximately 4 million points. 
A scan like this takes approximately 12 minutes. (The operator chose not to scan the ceiling but
could have. This would have captured all the data overhead in the same amount of
time. The range accuracy is better than
1/4in. The data that appears
curved, like the edge of the floor or the top of the closet, results from
displaying this 3D data as a 2D projection. These are not distortions in the
data. When displayed in 3D these edges display correctly.
This image shows the control software for the
DeltaSphere-3000 and the same scanned data displayed in the image above. This is
more than an image - it contains the 3D coordinates for every point in the image.
As soon as this data is acquired
you can measure the distance between any two points. The small circle on the
right highlights a single point identified on the wall. The circle on the left highlights the location
of the cursor (not shown) at a point on the foot. The circle below shows the distance between that point on the
wall and wherever the cursor is moved in the scene. In this case, the foot is
26.69 inches from the wall. New SceneVision
software makes this operation even simpler.
Using the scanned data and images captured, you can create a
3D model of the entire scene, or of objects in the scene. This image shows the
data, which has been processed and simplified (using
PolyWorks® software from InnovMetric), as a 'wire frame' model
. This
model can be viewed from any viewpoint in a graphics viewer. It can also be displayed with full color
captured at the scene.
This image shows the same data viewed with actual scene
color 'mapped' to the model above. This is not just an image - it's a full, 3D
model. The DeltaSphere comes with tools for mapping color to the 3D data.
Once the model is created, it can be viewed from any
viewpoint in real time on any standard PC. The 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.)
The images below were all created from a single scan of a
garage. They show views of the scene from a distance, close up views, and
a view from directly overhead - something that's difficult or impossible to
capture with a standard camera. (The DeltaSphere 3000's tripod was located in
the center of the circle on the floor. The operator chose not to scan directly
overhead - but could have with no additional time spent.)
The image below is an overhead view of the garage. When using a video camera, if
you want a view from overhead you need to place the camera overhead. Using
DeltaSphere 3D scene digitizer is different. Once you've created a model of a
scene, you can look at it from any viewpoint - even from locations where you
never placed the DeltaSphere.
