THE FAST AND EASY DIGITAL SCANNER

The new FastSCAN Cobra™ is 30% less expensive and 50% smaller, while retaining all functional capability, allowing continued ease of use and greater portability. FastSCAN Cobra instantly acquires three dimensional surfaces by gathering measurements made by smoothly sweeping a handheld laser scanning wand over an object - in a manner similar to spray painting. The object's image instantly appears on your computer screen and the finished scan is processed to combine any overlapping sweeps, significantly reducing the time to develop surface models of virtually any object with little or no metal content. The three-dimensional data can then be saved in industry-standard formats for loading into other programs.

FastSCAN Cobra is designed to scan non-metallic, opaque objects. The scanner works by casting a fan of laser light over the object, while the camera on the wand views the laser to record a cross-sectional profile of the object. The embedded FASTRAK™ is used to determine the position and orientation of the wand, enabling the computer to reconstruct the full three-dimensional surface of the object. Moveable objects may be scanned by attaching a second receiver to the object.

 

New Stylus Marker Functionality Option

Once initialized, pressing the stylus button generates a position and orientation marker within the tracker's spatial system. These coordinates are recorded by the FastSCAN Cobra software and displayed on the screen. Digital reference markers provide an indication of the exact position and orientation of the marked point. The digital reference can then be exported.

 

FastRBF Extensions Option

FastRBF extensions offer key scanning benefits:

  • Automatic hole filling

  • Smooth extrapolation of surfaces

  • Mesh simplification with scan detail preservation

  • Export guaranteed closed, water tight meshes

  • Mesh is characterized by more uniform triangles

  • Low pass filtering (smoothing) of scans

Auto stitches 3D images as you scan

Fast and flexible

Compact and portable

Quick and easy to set up

Minimal shape restriction

Scans moveable objects

Exports scanned object to industry standard formats

 

Export Smoothing

 

Two exports of the same surface at different export smoothing parameters. The Export Smoothing parameter controls how much smoothing FastSCAN Cobra uses when merging sweeps. A low value creates a more detailed surface, but will fail to merge more widely separated sweeps. A higher value will merge sweeps better, but will remove more surface details.

 

Its uses are as unlimited as your imagination!

  • Animation

  • Archeology

  • Architecture

  • Broadcast & Movies

  • Computer Games

  • Education

  • Industrial Design

  • Medical

  • Multimedia and Web Design

  • Rapid Prototyping and Reverse Engineering

  • Research

 

Scanning People

The handheld laser scanner can be used to digitize a human shape for animation, multimedia, custom apparel design, biomedical research, forensics, etc. The following example demonstrates the scanner's ability to:

  • scan a human subject rapidly while subject remains still

  • use the second receiver on a headband to track involuntary movement of the subject

  • scan a complicated surface with convolutions that would normally be obscured from a conventional turntable-based laser scanner

Scanning Objects

The handheld laser scanner can be used to digitize the surface of objects for animation, rapid prototyping, 3D measurement, archiving, etc. The following example demonstrates the scanner's ability to:

  • rapidly digitize the complete 3D surface of an object

  • save the data in industry standard formats to be used by other programs

 

Scanning Large Objects

The handheld laser scanner has been used by Ross Clarke of the Meat Industry Research Institute NZ to scan lamb and beef carcasses for 3D modeling by Andrew Pullan of Engineering Science, Auckland University. This demonstrates its ability to:

  • scan large objects

  • scan objects that are not rigidly mounted by attaching the reference to the object

  • take the scanner to the object

  • scan in harsh environments
