31 Oct 2008 ViALUX presents the 2nd generation of its DLP® based 3D camera. The compact device combines latest CCD camera technology with the outstanding switching rate and precision of the digital light projection. The new z-Snapper design led to reduced size and weight at increased speed and light efficiency.
The following properties enable efficient use in a wide range of applications:
- short measuring time ≥40 ms for a cloud of 300.000 (x,y,z) triples high accuracy, typically ≤ 0.1 mm for 500 mm field of view
- 3D data without the need of any mechanical movement
- synchronized use of multiple sensors with data output in the same coordinate system
- 4D operation mode for the recording of 3D sequences of dynamic scenes; 25fps@VGA resolution and 45fps@½VGA resolution, respectively
- support of additional calibrated cameras, e.g. for colour texture recording
- support of customer defined pattern projection for augmented reality applications
- ultra-portable by battery option and passively cooled LED light source
- rugged compact size housing (230x130x115 mm³) and only 2 kg weight
The z-Snapper 3D camera comes with a powerful software package that includes:
- the automatic system installation from DVD
- the convenient application program for system settings, 3D data acquisition, advanced 3D visualization, data export and analysis
- the comprehensive application programming interface (API-DLL) for rapid system integration
- the system self-calibration tool based upon photogrammetry
Applications are found in different areas where the access to the 3rd dimension is a valuable add-on.
Speed and precision of the z-Snapper 3D camera are essential for the use in industrial machine vision. Examples for product inspection are the dimensional monitoring of cast housings, the quality assurance for welded wire joints, and the PCB solder paste volume measurement.
The quick availability of 3D object data led to new approaches in automation&robotics. The portioning of salmon filet into pieces of equal weight or the 3D guided pick-up of objects by a robot are good examples. Object recognition can be significantly improved.
The ability of the z-Snapper to back-project any points or patters onto the 3D object surface is an outstanding feature enabling augmented reality systems. It has found application in the field of automotive crash test preparation.
Non-industrial applications can be divided in living and non-living scenes. Samples for the latter ones are traces on sites of crime like outdoor tire traces or shoe traces as well as 3D records of cultural goods.
The 3D still or video camera for the capturing of human beings is applied in medicine for orthopaedic purposes, for cosmetic surgery, and for patient position monitoring in radiotherapy. Scanning persons for biometry or for the production of custom tailored clothing are other examples.
