Update calibration
After the calibration is completed, if the splitting effect of the "marker" point in the 3D view is not good, or if the calibration time is too long apart from the usage time, resulting in poor results, you can update the calibration to keep the camera in Live playback mode. Open the "Calibration Pane",and select the "Update" option in the window. Updating the calibration does not require placing an L-shaped rod first, But it is necessary to ensure that there are no other miscellaneous points in the field of view except for the T-shaped pole. If there are any miscellaneous points in the camera's field of view, you can repeat the steps of "Preparation for calibration"；
Click "Next" and proceed to the T-calibration. In the T-calibration window, if you are loading a calibration file that has been merged with partition calibration, select the area number for updating calibration in "Area". If you want to update the entire area for calibration, select "All" and check the "Protect Current Camera Correction" option to prevent camera parameters from being modified during the update calibration process；
Repeat steps 4 and 5 of 'Initial Calibration' to perform T-calibration. After the calibration time is up, click "Next" and the software will automatically calculate. After completion, the calibration result will be displayed in the window (such as "Poor", "Normal", "Good", "Perfect", if the calibration result shows "Poor", it is recommended to recalibrate, otherwise it can be saved and used normally). Click "Next" to perform L-type calibration；
Place the L-shaped rod into the field and ensure that there are no other miscellaneous points except for the four points of the L-shaped rod. Click "Next" to perform the L-shaped calibration. After the calibration is successful, click the "Finish" button to complete the calibration. Click the "File Save Calibration File" option in the bottom right corner of the software interface to save the updated calibration configuration file. If the L-shaped calibration fails, a pop-up window will prompt；
L-type calibration failure may be due to：
In addition to the four points of the L-shaped pole, there are other miscellaneous points in the field that cause the software to be unable to correctly recognize the L-shaped pole；
During the update calibration, perform L-shaped calibration. The position of the L-shaped rod should be aligned with the position of the L-shaped rod during system calibration, and the difference between the two should not be too large；
The selected L-shaped rod length parameter is inconsistent with the actual L-shaped rod length parameter. For specific settings of L-shaped rod length parameters, please refer to the instructions in "Calibration Settings"；
Solution to L-type calibration failure during update calibration：
Eliminate environmental factors and remove other miscellaneous points in the site except for the four points of the L-shaped pole；
Is the L-shaped rod parameter in the self-test software setting consistent with the actual L-shaped used；
Click Previous to return to the previous step and perform the L-type calibration again；
If the calibration still fails, please consult the technical engineer.
When updating the calibration, if the user does not need to update the coordinate system position in the 3D view after the T-shaped calibration is completed, there is no need to perform L-shaped calibration. Click Finish to save the updated calibration file. After the L-shaped calibration is completed, the coordinate system in the 3D view will be consistent with the placement position of the L-shaped rod during the L-shaped calibration.
