The only hardware requirements are a simple commercial hand-held laser and a standard camera.
Feature
Compatible to most cameras with Microsoft Windows drivers (WDM):
You can use nearly every MS-Windows compatible camera with WDM support, like your web-cam or fire-wire camera. You can even use your camcorder if you can connect it to your PC (and if you have suitable WDM drivers).
Feature
Precise and automatic camera calibration:
It is not possible to get accurate 3d data with an uncalibrated camera. Fortunately DAVID provides a well-integrated and easy to use calibration for automatic computation of the camera's pose and focal length, as well as for compensation of radial lens distortions. Therefore you can accurately scan your objects with absolute scale.
Feature
Data smoothing and interpolation:
By moving the laser like a paintbrush, you can sweep over the object until the scan results are smooth and all gaps are filled. Beside that, you can use the gap interpolation and smoothing filters of DAVID to refine your scans.
Feature
Texture support:
You can grab a camera shot that will be used as texture. The texturized 3d model can be inspected in the 3d window. Furthermore DAVID exports texture coordinates, which allows you to import the textured object in third-party software.
Feature
Integrated 3d viewer:
Inspect your 3d model right after scanning with the integrated OpenGL-based 3D viewer of DAVID.
Feature
File export:
Save your scanned object as Alias Wavefront OBJ file. The OBJ-format is an well-established plain text format for triangle meshes and is supported by many 3d applications. (Further file formats can be exported with DAVID-Shapefusion.)

Features of DAVID-Shapefusion

With DAVID-Shapefusion you can merge multiple scans that were made from different sensor directions in order to get a complete 360 degree model. This allows you to move the object freely between different scans.
Feature
Outlier removal:
By moving a simple slider you can choose which surface segments will be removed and which will be retained. A preview of the result is shown in a 3D window.
Feature
Automatic and user-driven alignment:
A precise alignment of your scans is very easy. Just choose one of six different registration modes and a few seconds and mouse clicks later, you get the aligned result.
Feature
Robust surface fusion:
You can fuse/merge the aligned scans with a single mouse click. The result is a connected regular triangle mesh. Our fusion method is more than just an ordinary mesh stitching, since it calculates the average of overlapping surface parts and reduces noise and outliers.
Feature
User-defined mesh resolution and mesh smoothness:
You can define the mesh resolution and smoothness value to optimize the fusion result for your intended application.
Feature
OBJ, PLY, and STL file export:
Choose between the OBJ, PLY, and STL file format to save your fusion result or your aligned and filtered 3d scans.

Advantages over other systems:

The flexible scanning technique of DAVID has several advantages over other systems.
Feature
User-friendly handling:
The user interface of DAVID is easy to use and the scanning process is very simple.
Feature
Manual laser movement:
You can manually sweep the laser line over the object like a paintbrush. The illumination direction is flexible and allows an interactive avoidance of laser shadow problems and outliers. Only the lightweight laser has to be held and therefore allows a convenient scanning process.
Feature
No need of a rotation table, no expensive actuators:
You need no actuators for rotating/translating the laser plane or for rotating/translating the object. Therefore it is also possible to scan e.g. heads and fixed statues.
You can scan the objects from all sides, even from the top and the bottom.
Feature
Scalable setup:
Our approach is very scalable. You can simply scale the whole setup up or down to scan small or big object sizes.
Feature
Hardware can be reused for other applications:
Since DAVID is a pure software solution that does not rely on specific hardware, you can save money and re-use your own hardware (especially your camera) for other applications.

In the future...

Short-term plans for future versions.
Feature
Texture fusion:
Stitch/merge multiple textures in order to get a complete 360° texture.
Feature
Export of *.swf (flash) and/or java files :
Export your object to an internet-compatible 3d format and use it for your 3d product presentation in the internet.
