As of the release of iSTAR Pulsar firmware v2.5.4 on 25th November 2019, capture modes have largely been locked-down so that they always use the same rate of capture. Two additional capture presets have been added to allow capture at a custom rate either outdoors or indoors if desired - for this, users must use the "Custom Outdoor" or "Custom Indoor" presets.
Please consult the article on Capture Presets for more information on this.
Data that will be downloaded directly from iSTAR Pulsar+ and processed offline in Immersive Studio may be captured and processed in one of two ways:
- Data is captured at the maximum rate of 7fps - users may then specify in Immersive Studio the frames to be extracted and stitched based on either time or distance
- Data captured at a custom rate, anything other than 7fps, will be be processed as-is in Immersive Studio - all frames captured will be stitched.
Users may switch to and configure their preferred capture rate method by connecting their mobile device to the iSTAR Pulsar unit, launching the mobile app, and browsing to the "Settings" option in the main menu:
Within the "Preferences" tab, users may select a custom capture preset, and will then see further options to configure rate of capture. Users may toggle between Image Count Spacing and Distance Spacing and use the slider shown to select an appropriate value:
Distance Spacing
Users may configure their device to capture a frame at a set distance - for example, the capture preset "Drive" is set to capture at 4 meter spacing, so a frame for every 4 meters travelled.now enable Distance Spacing and customise this as follows:
| Setting Value | Capture Rate |
|---|---|
| 0 m | 7 frames per second (no distance spacing applied) |
| 1 m | 1 frame per meter traveled |
| 2 m | 1 frame per every 2 meters traveled |
| 3 m | 1 frame per every 3 meters traveled |
| 4 m | 1 frame per every 4 meters traveled |
| ... | ... |
| 20 m (max value) | 1 frame per every 20 meters traveled |
Distance space requires a iSTAR Pulsar to have a GPS lock in order to operate, therefore this is not selectable when capturing using an Indoor capture mode. In areas where GPS signal may be limited, users are advised to use Image Count Spacing.
Image Count Spacing
Allows users to set their device to capture frames at a set frequency as opposed to at set distances as above. As iSTAR Pulsar's maximum rate of capture is 7 frames per second, the available custom values are fractions of 1/7.
