   Scroll pagebreak

   Note that, as usual, the color of the icons at the top of the Cameras view provides an additional indication of the camera status.

   

   This icon represents the centroid connection score: for the selected camera, the percentage of centroids that are contributing to reconstructions. A low centroid connection score (as shown in the above example), indicates issues with the selected camera.

4. Hover the mouse pointer over the Average reprojection error icon:

   This icon represents the reprojection error: the distance between the 2D image of the markers on the camera and the 3D reconstructions of those markers projected back to the camera sensor.
5. To investigate camera status further, hover the mouse pointer over any additional camera status icons to the left or right of the other two icons. These additional icons provide further information about the state of the camera: eg, a bumped camera icon and/or a camera temperature warning.

   

   For information about bumped cameras, see Fix bumped cameras.
   If one or more camera's operating temperature is inconsistent with its temperature at calibration, re-calibration is necessary (see Calibrate cameras).
