Cyra Targets

Targets represent previously measured points

Targets Are Used For The Registration Process

Target Pattern is Automatically recognized by software

Software

Z&F Laser Control Software

Bentley MicroStation V8i software

LFM Modeller & Server software

Matlab, Surfer and Arc Map software

Scan Registration

CAD Modeling Scan Processing

Generate Contour Lines

Before Registration After Registration

Registered Scans

Method

First Use Leica GPS RTK to determine the (X,Y,Z) coordinate points for the Z&F 3D Laser Scanner & Target Locations.

Setup Z&F 3D Laser Scanner & Target At Points & Perform Scans Around Selected Project Area.

Using Computer Software Register Scans, Create 3D Model, & Contour Lines For Topographic Map

Results

Contour Lines Can Be Generated

Conclusion

Initial Scope-To Develop A Method Using Surveying Techniques & Instruments To Create A 3D Topographic Map of Small Project Area

Results-Develop A Method That Created A 3D Scan Overview of the Project Area That Can Be Used As A 3D Topographic Map
