HP 3D - Software to Create a Low Cost 3D Scanner
The HP-laserscanner is a very low-cost system for contact-free scanning
of 3d objects. The only hardware requirements are a data projector and
a vision camera. Starter kits are available to help get you scanning
in a short
Try the HP
S3 scanner kits for plug and scan.
If you don't want to start
searching and tinkering,
Starter-Kit contains all necessary hardware and software to set
up your own 3d scanner!

3. Start scanning by
aiming the camera at your object and pressing a button.
4. Gaze at the 3D window and export your result to .OBJ
5. Optional: Automatically stitch several

Features of HP Laserscanner
Compatible to most cameras with Microsoft Windows drivers
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
Precise and automatic camera calibration:
It is not possible to get accurate 3d data with an uncalibrated
camera. Fortunately HP 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
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.
that, you can use the gap interpolation and smoothing filters
of HP to
refine your scans.
You can grab a camera shot that will be used as texture. The
texturized 3d model can be inspected in the 3d window. Furthermore
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 HP.
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
Features of HP-Shapefusion
With HP-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
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
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
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
just an ordinary mesh stitching, since it calculates the average of
overlapping surface parts and reduces noise and outliers.
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 HP has several advantages over
The user interface of HP is easy to use and the scanning process is
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
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 HP 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.
