By using the video, and selection points from the image, a region can be defined. To do so perform the following steps:
Select the Add Region button and left-click in the graphics to define a polygon, use left-click to define anchor points for the region and right-click to complete the polygon, or Escape to cancel.
A “Region” has a single set of Point 2 Point Distance parameter to define the density of the scan. This density is defined from the distance to the anchor points. Be sure to define anchor points on the object you which to scan. A tighter grid will result in a longer scan time. It also has Grow / Shrink Width setting that allows you to expand or contract the size of an entire polygon. This can be quite helpful when you are trying to measure all of an object. You can first click to define a region by clicking on the object you wish to scan and then expand that region to encompass the entire object.
Add additional polygons within a region definition through use of the Add Polygon button, if needed. Select a polygon and chech or uncheck a box to toggle the polygon from interior / exterior in order to define exclusion zones.
Add additional Regions to the OVC as desired to define regions with different point resolution as part of a single scan.
Scan the part using either the red scanner button in the Toolbar or the scan button within the KeyBoard Drive dialog.
Do not use the full tracker interface Measure button or you will trigger a measurement using the saved perimeters within the selected measurement profile (see below).
By using the video, and selection points from the image, a Line can be defined. To do so perform the following steps:
By using the video, and selection points from the image, a region can be defined. To do so perform the following steps:
Select the Add Line button and left-click in the graphics to define a polyline, use left-click to define anchor points for the line and right-click to complete the polyline, or Escape to cancel.
A “Line” has a single set of Point 2 Point Distance, Line 2 Line Distance, and Line Width, parameters to define the density of the scan and its spacing. This density is defined from the distance to the anchor points. Be sure to define anchor points on the object you which to scan. A tighter grid will result in a longer scan time.
Linear scans - are just as you would expect, a single scan path from point A to point B along a polyline.
Cross Lines - offer an additional width to define a series of cross sectional scans along a defined polyline.
Add additional Polylines within a Line definition through use of the Add Polyline button, if needed.
Add additional Lines to the OVC as desired to define Lines with different point resolution as part of a single scan.
Scan the part using either the red scanner button in the Toolbar or the scan button within the KeyBoard Drive dialog.
Do not use the full tracker interface Measure button or you will trigger a measurement using the saved perimeters within the selected measurement profile (see below).
Measurements can be taken directly from the OVC camera using mouse clicks. This can be done using the play button in the drive control:
