Crime, Accident, and Fire Scenes

What can the Focus3D Laser Scanner and SceneVision-3D Software do for you?

(Click on any image below for a larger version.)

 

 

At the scene - capture the scene in 3D and color with the Focus3D Laser Scanner

  • Capture 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.
  • Photograph - 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 insets.

On your laptop - view, measure, diagram, reconstruct, present with SceneVision-3D software

  • Measure 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.
  • View 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 spatter trajectories.
  • 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 that location.
  • Automatically produce and display the location of the camera for any photo taken with the DeltaSphere camera.
  • 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 any scale.
Capture Measurements

The image 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 correctly.
Color images taken automatically by the Focus3D are transferred automatically to the laser data and can be used to produce full color, 3D, computer graphics models of a crime scene.. 
Measure

This 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..

Model

Using 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.

View

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. SceneVision includes tools for creating these solid, full color, 3D computer graphics models. 

Viewpoint Locations

A person's location is illustrated with a vertical line and pyramid at the eye height as shown in the image on the left. Clicking on the pyramid changes the viewpoint to exactly what a person would see in that position. 

 

Outline

This image 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.

Blood Spatter

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.

Photo Hot Spots

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.)
