DAVID-laserscanner in action

DAVID-laserscanner is a very low-cost system for contact-free scanning of 3D objects. The only hardware requirements, which are included in our Starter-kit, are a hand-held laser and a camera.

The Lasers provided in the David Starter-Kit are very low power and are designated completely safe for use (Class 1), even in the Classroom!

With DAVID-Shapefusion you can merge multiple scans that were made from different sensor directions in order to get a complete textured 360 degree model. This allows you to move the object freely between different scans.

Features of DAVID-laserscanner

	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)
	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.
	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. Besides that, you can use the gap interpolation and smoothing filters of DAVID software to refine your scans.
	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.
	Integrated 3d viewer
	Inspect your 3d model right after scanning with the integrated OpenGL-based 3D viewer of DAVID.
	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

	Outlier removal
	By moving a simple slider you can choose which surface segments will be removed and which will be retained. Also you can delete surface parts easily with your mouse. A preview of the result is shown in a 3D window.
	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.
	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.
	Texture support
	In all alignment and fusion steps, textures are processed along with the 3d data. The result is a fused triangle mesh with a fused texture.
	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.
	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.
	User-friendly handling
	The user interface of DAVID is easy to use and the scanning process is very simple.
	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.
	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 heads and fixed statues, for example. You can scan the objects from all sides, including top and bottom.
	Scalable setup
	Our approach is very scalable. You can simply scale the whole setup up or down to scan small or big object sizes.
	Hardware can be reused for other applications
	Since DAVID is largely a 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... further plans for future versions
	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 on the internet.
