Point Cloud View (3DPM and 3D Stereo)
The point cloud view offers the following advantages:
• Helps the user visualize the measurement to ensure proper cursor placement
and verify 3D data quality.
• Shows location of high and low points to help profile and depth cursor
positioning.
• Shows the level of noise relative to indication size. Move the probe tip closer
or adjust viewing angle if surface noise bumps appear significant relative
to the indication size.
• Shows ripple or waves, which may indicate dirt or oil on the gratings or reflections
bouncing off one surface onto another.
The MViQ offers two different point cloud image options: Full Image and
Measurement Image, either of which may be viewed full screen or in a split
view with the left-hand view containing the 3D Stereo or 3DPM image for
simultaneous cursor placement and point cloud inspection. In 3DPM split
view, the 2D image may be zoomed and panned using the touch screen.
The following apply to both Full Image (
1
) and Measurement Image (
2
):
• The cursor positions and the lines between the cursors are shown (
3
).
• For Depth Profile and Area Depth Profile, the profile slice along the surface
is shown.
• For Depth, Depth Profile, Area Depth Profile, and measurement utilizing a
Measurement Plane, a blue rectangle in the point cloud view indicates the
reference plane position (
4
).
• When a Measurement Plane is used with Point to Line, Area, or Depth
measurements, an Edge View Angle and Line (
5
) are shown to aid proper
view setup.
• Drag a single finger over the touchscreen (or use the joystick) to rotate the
point cloud.
• Use two fingers to shift or rotate the point cloud clockwise or counterclockwise.
• Slide two fingers together or apart to increase or decrease the zoom level
or select Zoom.
• Press Reset to return to the default view (second level
6
soft key).
With Full Image, the following apply:
• Shows all 3D data and all measurements with the active measurement
shown in bold.
• The colorized Depth Map indicates tip-to-target distance.
• Dotted lines show the corners of the field of view to help visualize tip and
surface positions (
7
). These are controlled by the 3D Perspective Lines
option on the Measurement and Annotation Settings panel.
With Measurement Image, the following apply:
• Only the active measurement and the 3D data near it are shown.
• With Depth Map on, a scale indicates the depth or height relative to the
reference plane.
