How to quickly create a compelling 3D crime scene reconstruction
Karen Hughes, Training Manager at Leica Geosystems, explains
Hi, I am Karen Hughes, Training Manager at Leica Geosystems, part of Hexagon.
I will show you how to create compelling crime scene reconstruction using the point-cloud data collected from three different sensors: an RTC360, a BLK360, and a BLK2GO.
After the data is collected at a scene, it is imported into Cyclone REGISTER 360 and combined to show the entire scene from any perspective.
The green link shown on the site map and the low link errors indicate that the scene is tightly stitched together.
Cross-sections through the point cloud using the TruSlicer tool verify the scene as aligned correctly.
A 1-metre pole certified by NIST is placed at the scene to measured after the data is collected to verify the accuracy of the data.
Evidence at the scene is marked by geotags, which enable investigators to attach images, video footage from cameras around the scene, witness statements and other pertinent information.
Limit boxes can isolate specific areas of interest, such as evidence and trajectory rods. They can also be used to remove the ceiling of a room or the top of the building to present a bird' s-eye view of the scene and aid navigation.
The crime scene is published from REGISTER 360 in the LGS format. The LGS file is opened in Map360 for detailed crime scene analysis.
TruView, our free viewer, navigates through the scene and presents the data easily.
