This topic discusses the controls located at the bottom of the Vision tab.
Live View Freeze - This button "pauses"
the update of the Live View display. This is useful if you want to keep
something on the screen to analyze or take a screen capture, but you want
the measurement to continue in the background. To restart the Live View
update, release this button.
Move to Previous Hit Target - This button moves
the Field of View (FOV) to the previous target in a list of targets.
Skip Backwards on Hit Target - This button moves
the FOV part way backward along a target towards the previous target.
This helps you see how an entire feature might be measured even though
the entire feature does not fit inside the FOV.
Skip Forwards on Hit Target - This button moves
the FOV part way forward along a target towards the next target. This
helps you see how an entire feature might be measured even though the
entire feature does not fit inside the FOV.
Move to Next Hit Target - This button moves the
FOV to the next target in a list of targets.
Snap Mouse Clicks to Edge - This button causes
selected points for feature creation to snap to the closest point along
the nearest edge. If this button is not selected, points remain where
they are clicked. For more information on this feature, see "Setting
Up the Live View".
Snap Mouse Clicks to Edge is also used at execution time for Manual Targets. If this option is on, and you drag and drop a manual target, PC-DMIS will do an edge detection to snap the crosshair to the edge.
AutoShutter - This button enables AutoShutter
capability to measure features. For more information on this feature,
see "Setting up the Live View".
Feature Compass - This button causes the AutoCompass
to display an arrow and the distance to move for the next target. For
more information on this feature, see "Setting
up the Live View".
Show Hit Targets - This button toggles the display
of targets in the Graphic Display window or the Live View. This is the
same functionality as the show target button on the Auto
Feature dialog box. This is particularly useful when you are using
the Quick Start window and the Auto Feature
dialog box is not open.
Lock Target To Part - When you select this button,
the software locks the display of targets in the Graphic Display window
or the Live View. If this is locked, you cannot click and drag the target
to a new location on the Vision tab.
Show Gray Scale - When you select this button,
the software shows a gray-scale depiction of the Vision
tab. This button only appears when a color camera is used. For black-and-white
or monochrome cameras, this button does not appear.
Overlay Transparency - When you select this button,
the software 
displays
a slider underneath it. You can drag the slider to
set the transparency of the overlays displayed within the Live View. The
transparency dynamically updates as you drag the slider. This is the only
place that you can change the overlay transparency. The default value
is 50%. 0% = fully transparent. 100% = solid.
Magnification - When you select this button,
the software displays
a slider underneath it. You can drag the slider to
set the magnification of the Live View without having to use Magnification
tab on the Probe Toolbox. The magnification dynamically updates as you
drag the slider. For more information on magnification, see "Probe
Toolbox: Magnification tab".
Display Gage - When you select this button, the
software toggles the display of the currently selected gage overlay. Select
the black down arrow to display the Gage
Selector toolbar underneath the button, enabling you
to select a different gage type to be displayed. For more information
on gages, see "Probe Toolbox:
Gages tab".
AutoVoid - When you select this button, the software
performs a void detection for the currently edited feature. It automatically
adds targets with zero point density at the detected void areas.
SensiFocus - This button executes an automatic
"sensible focus" on the center of the Vision
tab.
On a DCC machine, it automatically moves the stage and then returns it to the focus position. The parameters used for this focus do not come from Focus tab of the Probe Toolbox. Instead, they are based on available data such as pixel size, depth of focus, frame rate, and so on. The focus target size is fixed and located in the center of the Vision tab.
On a manual machine, this button is disabled.
SensiLight - This button performs an on-the-spot
automatic "sensible lighting" adjustment in an attempt to achieve
optimal results. The Illumination tab will quickly
be selected as this automatic adjustment is made. For additional information
on how SensiLight is used as a parameter for edge features, see the SensiLight
description under "Automatic
Hit Target - Edge Parameter Set".
Illumination Adjustment - This button toggles
the display of the Illumintation
Overlay on the Vision tab
so you can make adjustments to the illumination. For more information
on illumination, see "Probe
Toolbox: Illumination tab".
Laser On/Off - This button toggles the laser
on and off. This is available for systems with a laser probe or laser
pointer fitted (such as TESA VISIO 300 and 500).
