Main Page → Calibration → Continuous Calibration
The 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 to provide the most globally optimized tracking system.
For continuous calibration to work as expected, the following criteria must be met:
To enable Continuous Calibration, calibrate the camera system first and enable the Continuous Calibration setting at the bottom of the Calibration pane. Once enabled, Motive continuously monitors the residual values in captured marker reconstructions, and when the updated calibration is better than the existing one, it will get updated automatically. Please note that at least some number of markers must be being tracked in the volume for the continuous calibration to work. You will also be able to monitor the sampling progress and when the calibration has been last updated.
The status of continuous calibration can also be monitored on the Status Log panel.
Active anchor markers can be set up in Motive to further improve continuous calibration. When properly configured, anchor markers improve continous calibration updates, especially on systems that consists of multiple sets of cameras that are separated into different tracking areas, by obstructions or walls, without camera view overlap. It also provides extra assurance that the global origin will not shift during each updates; although the continuous calibration feature itself already checks for this. Please note that only active markers can be assigned as calibration markers. This is not supported for passive markers.
Follow the below steps for setting up the active anchor marker in Motive:
