Main Page → Calibration → Continuous Calibration
The new Continuous Calibration feature ensures your system always remains optimally calibrated, requiring no user intervention to maintain the tracking quality. It uses highly sophisticated algorithms to evaluate the quality of the calibration and the triangulated marker positions. Whenever the tracking accuracy degrades, Motive will automatically detect and update the calibration and provide the most globally optimized tracking system.
For continuous calibration to work as expected, the following criteria must be met:
There are three different modes of continuous calibration: Continuous and Continuous + Bumped.
The Continuous mode is used to maintain the calibration quality, and this should be utilized in most cases. In this mode, Motive monitors how well the tracked rays converge onto tracked markers, and it updates the calibration so corresponding tracked rays converge more precisely. This mode is capable of correcting minor degradations that result from ambient influences, such as the thermal expansions on the camera mounting structure.
This mode requires markers to be seen by all of the cameras in the system in order for the calibration to be updated.
The Continuous + Bumped mode combines the continuous calibration refinement described above with the ability to resolve and repair cameras that have been bumped and are no longer contributing to 3D reconstruction. By utilizing this feature, the bumped camera will automatically resolve and be reintroduced into the calibration without requiring the user to perform a manual calibration. For just maintaining overall calibration quality, the Continuous mode should be used.
The continuous calibration can be enabled or disabled in the Application Settings pane under the reconstruction tab. Set the Continuous Calibration setting to Continuous, or Continuous + Bumped to allow the feature to update the system calibration.
The status of continuous calibration can be monitored on the Status Log panel.
Duo/Trio Tracking Bars:
Duo/ Trio tracking bars can utilize this feature to update the calibration of tracking bars to improve tracking quality.
Do not use continuous calibration for updating calibration with cameras that have been moved significantly or repositioned entirely. While this feature may be able to handle such cases, this is not the intended use. When a camera is moved, you will need to manually calibrate the volume again for the best tracking quality.
