Users Manual

• type: Enumeration, is always DisparityC
• description: Mode for the depth measurements, which is always DisparityC.
Scan3dFocalLength (read-only)
• type: Float
• description: Focal length in pixel of image stream selected by ComponentSelector. In case of the
component Disparity, Confidence and Error, the value also depends on the resolution that is im-
plicitely selected by DepthQuality.
Scan3dBaseline (read-only)
• type: Float
• description: Baseline of the stereo camera in meter.
Scan3dPrinciplePointU (read-only)
• type: Float
• description: Horizontal location of the principle point in pixel of image stream selected by
ComponentSelector. In case of the component Disparity, Confidence and Error, the value also
depends on the resolution that is implicitely selected by DepthQuality.
Scan3dPrinciplePointV (read-only)
• type: Float
• description: Vertical location of the principle point in pixel of image stream selected by
ComponentSelector. In case of the component Disparity, Confidence and Error, the value also
depends on the resolution that is implicitely selected by DepthQuality.
Scan3dCoordinateScale (read-only)
• type: Float
• description: The scale factor that has to be multiplied with the disparity values in the disparity image
stream to get the actual disparity measurements. This value is always 0.0625.
Scan3dCoordinateOffset (read-only)
• type: Float
• description: The offset that has to be added to the disparity values in the disparity image stream to
get the actual disparity measurements. For the rc_visard, this value is always 0 and can therefore be
disregarded.
Scan3dInvalidDataFlag (read-only)
• type: Boolean
• description: Is always true, which means that invalid data in the disparity image is marked by a
specific value defined by the Scan3dInvalidDataValue parameter.
Scan3dInvalidDataValue (read-only)
• type: Float
• description: Is the value which stands for invalid disparity. This value is always 0, which means that
disparity values of 0 correspond to invalid measurements. To distinguish between invalid disparity
measurements and disparity measurements of 0 for objects which are infinitely far away, the rc_visard
sets the disparity value for the latter to the smallest possible disparity value of 0.0625. This still
corresponds to an object distance of several hundred meters.
