ATS600 Scanning

Basic Scan Operations

The Over View Camera (OVC ) can be directly accessed from both the Toolbar (Figure 3-90) and the full instrument interface (Drive head/ OVC). Basic scan options can be performed directly from this control and do not require the use of any measurement profiles. This ap- proach is simple in that you define a region and can immediately scan that region, but does not offer the ability to save regions or control additional filtering. These options are available as part of a measure- ment profiles definitions (see following sections.

To perform a basic scan do the follow:

  1. Open the OVC camera using the Drive Beam Icon.

  2. Define regions and lines as desired. See section below for more information on the OVC controls.

  3. Press use the Red custom profile button (which is preset to OVC Scan for the ATS) to control start and stop of the scan.

 

This same basic scan control can be accessed from the OVC button in the full interface as well.

When the OVC Scan button is pressed the tracker will measure *All* the regions defined on the controller, both lines and polygons. Therefore you need to remove any definition you do not want to directly use. Specific regions can be saved as part of a measurement profile for use later if needed. The greater controls and options for this are as follows.

This independent measurement process can also be directly accessed from the full interface using the Drive Head/OVC button. The Camera but- ton will open the tracker OVC and the Scan button can be used to initiate a scan defined directly.

Linear or Cross-Line Scan:

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:

  1. 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.

  2. Add additional Polylines within a Line definition through use of the Add Polyline button, if needed.

  1. Add additional Lines to the OVC as desired to define Lines with different point resolution as part of a single scan.

  2. 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).

 

 

Saving Scan Region Definitions with Measurement Profiles

The definitions of scan Area and Line regions have been streamlined as follows:

 

The ATS600 also offers 2 primary default measurement profiles that can be edited and saved with user defined region definitions:

As always, these three are just default starting points, and you are free to define your own custom profiles. Note also that Stable Point measurement profiles also work very well with reflectorless measurements.

Regions used to define the extents of Area Scans are defined in advance as part of a measurement profile definition. To do so, select one of the predefined Area Scan profiles as the active measurement profile and press the View Selected Profile button to edit the profile settings.

An Area Scan profile offers the following settings:

NOTE: You can move the tracker head to the desired position, and click directly in the profile grid on the Min Distance and Max Distance labels to make the tracker set these by measuring the distance to the surface where it is pointing.

 

 

Operation

Notice at the bottom of the Measurement profile is a selection for the Operation this allows you to choose what type of data is sent to SA. So for example you want to send points rather than cloud points you can edit a profile to do that, or vice versa. With cloud points selected there is a buffer size that controls the size of the chuck of data sent to SA. So for example if you choose a buffer size of 2000 point and start scanning, SA will not get any data until this buffer is reached and then will receive 2000 points. This helps SA not get bogged down with a continual data stream.

Line Scans using Lines and Polylines

Line definitions provide an alternative way to measure either in a linear progression or using a series of crossing lines perpendicular to a poly line. This measure mode is accessed using a Line Scan Acquisition

A Line Scan profile offers the following settings:

*Note - Lines are saved as part of the measurement profile. To clear them out you will need to delete them from within the OVC and Save the measurement profile. You should then see a notification “No Lines defined in Line Scan mode on the controller”. Re-opening the OVC will re-import any saved regions from the measurement profile.
