3d scanning with DAVID 2.4.3
|
New version of free 3d scanning program DAVID 2.4.3 released.
The only requirements for building 3d scanner are: a simple commercial hand-held laser and, standard camera, two background planes and Windows PC with DAVID-laserscanner installed.
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).
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.
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.
Inspect your 3d model right after scanning with the integrated OpenGL-based 3D viewer of DAVID.
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.)
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.
The approach is very scalable. You can simply scale the whole setup up or down to scan small or big object sizes.
DAVID developers offer suite DAVID Starter-Kit, which includes a full tool set for 3d scanning available by 399,00 EUR.
On official site also available for customers: cameras by from 84,91 EUR, lasers by from 49,90 EUR scanning accessories.
