#### Live View Screen Elements

This topic discusses the various screen elements available to you within the Live View tab.

PC-DMIS Vision - Live View showing Tracker and Targets

The elements in the Live View can be altered by clicking and dragging the handles (green or yellow dots) to the desired location. Handles can control the size, orientation, and start and end angles for the targets.

T racker: The visual user interface to features. In the Circle feature illustrated above, the tracker shows the size of the circle (1a - green dotted circle between the lines of the bright yellow donut), and allows the Start angle (1b), end angle (1c), and orientation (1d - altered by dragging the green dot handle on the end of a line) to be changed.

Target: Individual addressable user interfaces to point detection. For each region, you can control each Target parameter by clicking in the target, or by dragging the handles. Target parameters are changed in the Hit Targets tab of the Probe Toolbox. In the Circle feature above, the circle has three targets (2a, 2b, & 2c). Each target has slightly different point detection parameters. 2a - configured with a smaller scan width. 2b - configured to detect NO points.

PC-DMIS Vision - Live View showing ROI and FOV coordinates

ROI (regions of interest): During run time, PC-DMIS Vision may need to divide a target into pieces so that each piece may fit into the FOV. ROIs are different from Targets in that the target may be bigger than the FOV. There is no user interaction with ROIs except for some visual indicators (3a - the AutoShutter halo for the upper left piece outlines the ROI; the target piece that can safely fit into the FOV at this magnification).

FOV Coordinates: The overlay numbers at the top and bottom of the screen, list the X and Y positions for the top left and bottom right corners of the FOV (4a). When right-clicking and dragging in the Live View other numbers appear in brackets which show the distance the camera will move. Additional information is given, depending on currently selected Probe Toolbox tab, but in the example above you see feature and target name.

AutoShutter & Auto Compass: According to the Live View Settings, any manual features that you measure with Automatic Targets will make use of a technology called “AutoShutter” and "AutoCompass". See "Setting up the Live View" for more information on AutoShutter and AutoCompass settings found in the Live View Setup dialog box.

Auto Compass: This will guide the operator to move the stage to get the next feature into the Field Of View, by showing an arrow and a distance to move.

You need to move the stage so the entire dashed rectangle box is comfortably within the Field Of View.

Auto Shutter: Once the target is within the Field Of View, a colored light countdown is shown on the Live View where it checks for stage stability, before automatically performing the edge detection on all targets that are within the current Live View.

Note: If a stage movement is detected during AutoShutter, it will discard the points and automatically restart the countdown to measure again.
