The GSI V-Stars Interface can be divided into 4 sections:
Section 1 - Provides data naming controls
Section 2 - Provides trigger functions to record data
Section 3 - Provides data type selection
Section 4 - Controls SA’s processing of that data
This section designates the Collection Group/Cloud and Target sent to SA for a particular target. Typically the target names sent to SA should match those used by V-Stars. To ensure this Check the Use VStars Label Check box. Checking the Inc check box will auto-increment Group/ Cloud names. When checked, the group or cloud name will automatically increment after each time data is sent to SA. In probing applications this should be turned off so that you can get multiple points in the same group(Figure 6-28).
Data triggering needs to be defined and set up within V-Stars. When in M-Mode either a single trigger can be sent or V-Stars can be set to a continuous mode. The buttons in section 2 then act as a start stop function for either M-Mode or S-Mode.
Trigger (M-Mode). The Trigger Button will initiate data trans- fer to SA in multi-camera mode. The data type sent is defined in the following section (Camera, Probe, Targets, Clouds (ProSpot), or Dream (6D)). This will either be a single event or a continuous transfer depending on the setting defined in V-Stars.
Data>>SA. Using the Data >> SA button will initiate an immediate project import from V-STARS. This is a great way to start and to get a constellation of points in SA to use as a frame of reference.
When a Trigger event is recorded data is sent from the interface to SA. The type of data sent is controlled by a set of radio buttons.
Data Source controls work as follows:
Camera. The camera transforms are sent to SA updating the camera positions shown in the graphics.
Probe. The most recent PROBE point is sent to SA. Checking the Avg chek box will send a single averaged point when the point count has been reached. Typically used in continuous mode.
Targets and Cloud (ProSpot). A filtered selection of particular target types can be sent based upon user selection (Figure 6-31). Selecting Cloud (ProSpot) will send data to SA in the form of a point cloud once a trigger event occurs. Note that the cloud sent will carry then name shown in the ‘Group/Cloud’ edit box.
The Set Labels buttons provide access to a filters control. They are used to set the V-Stars data types (labels) which will be sent when measuring either ‘Targets’ or ‘Cloud (ProSpot)’. The Targets data selection de- faults to “CODE”, and the Cloud (ProSpot) data selection defaults to “S”. The selections denote strings. When any of the selected strings are found in the V-Stars label of a point, that point will be sent to SA in the selected data form (‘Targets’ means points, and ‘Cloud (ProSpot)’ means a point cloud). To include additional data types simply check the use check box next to the data type.
Dream (6D). With this selected, under “Select Data Type to Send to SA”, if you select: Measurement, you will get point data with 6D data embedded. You can construct frames on these points using the embedded 6D data if desired. When set to Update, you will get 6D updates. With V-Stars M-Mode in “Continuous Trigger”, these updates can be used for 6D tracking (“TransTrack”) in SA. - Support for 6D tracking requires V-Stars v.4.9.1 or later.
Measurements. By default, the interface sends measurements to SA as points or clouds which are stored as such. This setting preserves this default behavior.
Update. Updates are not added to the SA Tree Database like Measurements. Rather, are used as updates for monitoring processes such as Watch Windows. Updates are meant to be used with Probe data (see section 3), but can be used with all but the Cloud data.
Batch Update. Originally intended for use with SA’s Instrument >> Automatic Measurement >> Measure Batch of Points, this command lets you transmit a batch of pts to the instrument, set tolerances, and update that set of points once the instrument sends the batch back to SA. Being photogrammetry, the V-Stars system sends them all back at once (those it can see at least).
V-Stars specific MP control can be obtained using the following commands:
Set Instrument Group and Target. Used to set the name controls in the interface for measurements.
Instrument Operational Check. This command includes a list of string based commands to set interface settings and perform basic operations. Refer to the MP Command Reference for a full listing of string commands.
