What's New in DAVID-Laserscanner Version 1.6:


New Features:
- Calibration: Eraser tool with blue preview box, “Mask all”-Button, pale blue instead of white for eraser image areas.
- Scanning: Improved compensation of lens distortions while scanning.
- Scanning: “Fast” Mode for scanning (reduced scan result display update to 1 Hz).
- Shapefusion: Scan alignment mode “Rotation around axis” allows to specify a known angle of rotation (useful in conjunction with a turn table).
- Shapefusion: New checkboxes to switch visibility of scans on/off
- Shapefusion: Command File Interpreter (start .EXE with a command line parameter and read the 'out.log' file for getting help).

Bugfix:
- Fixed Registration ID problem
- Correct display of calib points after restart of DAVID when scale factor is not 60.
- Fixed problem of eraser tool when mouse cursor leaves the camera window while pressing a mouse button.

Miscellaneous:
- Depth image: pale shades of gray no longer used –> improved visibility of scanned regions
- Shapefusion: “Are you sure”-dialog for the “Arrange” button to avoid losing registration result


What's New in DAVID-Laserscanner Version 1.5:


New Features:
- Enhanced sub-pixel detection of laser-line and increased scanning accuracy.
- Alternative 'Poisson' mesh fusion method, which is more robust against inaccurate scan alignment and which gives water-tight results.
- “Combine”-Button for grouping/combining of multiple scans to one scan
- Pairwise fine registration is much faster.

Bugfix:
- Eraser problem when camera window was scaled up or down

- STL export in DAVID-Shapefusion
- “Thin shadow line” mode for using cord shadow instead of laser
- Shows FPS in title of live camera window and scan result window

- Possibility to reload the scanning results
- Undo button for undoing interpolation and filtering

Miscellaneous:
- Conversion to Microsoft .NET Framework 2.0

Bugfixes:
- No more problems with floating point numbers for calibration scale
- fixed video grabber bug that sometimes caused freezing after auto repeat

- Eraser Mode added (user “cleans” image, very useful :-))
- When calibration fails, you get a more detailed error description
- solved problem that has occured if some calibration points have touched the image border.
- Manual mode added (user shows DAVID the calibration markers by mouse)
- Added “Invert” toggle for bright markers on calibration patterns (Advanced Settings- new function Remove
- dark background

Scanning:
- When triangulation angle is too low, user gets a warning and measured values are ignored

- Added radio buttons for green or red laser

Miscellaneous:
- Save mesh: texture coordinates are now conform with the OBJ-specification.
- msvcr71d.dll is not used anymore
- 3D-Window: improved automatic camera adjustment.
