Parameter Adjustment in NxView¶
This step-by-step procedure shall guide you to identify good stereo matching parameters for your respective scene. You can click the images on the left so see a larger screenshot or a short animation for each step.
Open the NxView parameter dialog and switch to the General tab.
Adjusting capture settings
Adjust the Target Brightness value such that you get a high contrast of the projected pattern in the camera images
It might be helpful to adjust the position or orientation of your camera or object in order to maximize projection contrast
Reducing ambient light also helps to improve image contrast and thus data quality in later steps
Select Quality Preset
Choose a settings preset according to your requirements. Use either a preset for static or dynamic scenes. Presets to the right provide increased data quality, presets to the left result in increased acquisition and processing speed.
Very long exposure times may lead to variable illumination or trigger delays. Please also read the illumination topic for your camera model.
If your computer is equipped with a CUDA enabled graphics card you should check if using CUDA results in increased performance. You can enable CUDA on the Global tab of the parameter dialog.
(optional) Increase Filling Region Size to fill small gaps with constant Z-value. This is only recommended for visualization. When processing 3D | data e.g. for searching CAD models filling should be switched off.
