Scan 3d Focal Length#

The Scan 3d Focal Length feature provides the focal length in pixel of image stream selected by Component Selector. In case of the component Disparity, Confidence and Error, the value also depends on the resolution that is implicitly selected by Depth Quality.

The focal length is required to compute the 3D object coordinates from the disparity values. A detailed description of the calculation can be found under: Processing measurement results
