Intersense OrientationWhen configuring offsets and settings for the Intersense IS-1200, you will also need to take into account the Intersense Orientation in relation to the production cinema camera.
To access the Airtrack/Intersense Configuration window, navigate to the Tracking Tab and, under Sync or Location, you will need to have them set your Sync and/or Location trackers as to Aitrack and/or Aitrack/Intersense respectively. Click on “Configure” next to either of these trackers to open this Configure window.
To enter the Intersense orientation, we reference the Intersense camera as pointing all the way forward, with the Intersense sticker facing up and with its connector sticking to the right as being 0 degrees for Pan and 0 degrees for Tilt. This is the Intersense’s default orientation.
- Yaw/Pan - refers to the rotation of the Intersense in a horizontal plane.
- Pitch/Tilt – refers to the rotation of the Intersense in a vertical plane
With that in mind, if we have the Intersense on top of the production cinema camera, pointing straight up, at 90 degrees (perpendicular to the cinema camera), the Intersense Orientation would be 90 degrees tilt.
Lightcraft’s omni mount for the Intersense is equipped with a spring detente pin that clicks in tilt position at every 22.5 degrees. So at every “click” the IS-1200 will be set to a known angle.
Intersense Orientation with Floor TargetsWhen using Portable Floor Targets, it is not uncommon to point the Intersense to the floor. In that case, the references are still the same, but the angles become negative numbers.
As a side note, some Intersense mounts have labels that say “front” and “back”. These, when the Intersense is pointing down, become reversed and “Front” actually points back in this configuration.
Outdoor TrackingOutdoors, where the targets are usually located to the left or right of the camera, the Intersense is then oriented to the left or right of the camera. With the Intersense label facing up, the following are correct orientation values:
- Intersense pointed to the right of the main camera: +90, 0 for pan and tilt
- Intersense pointed to the left of the main camera: -90, 0 for pan and tilt
