Once you are happy that the scene is correctly calibrated, verify the settings by dragging the
mimics around and comparing them to other people or people-sized objects in the scene.
The more locations in the scene where the calibration is verified, the more accurate the
calibration will be.
The 3 calibration parameters can be fine-tuned in the same way as detailed in Step 2.
Refer to the
Topic for information regarding additional calibration
tools that can help improve the accuracy of the calibration.
Once the settings have been successfully applied, objects in the scene are annotated with
height, area, speed and classification. To change the measurement units between Metric
and Imperial, please refer to the
Tip: If it all goes wrong
If you find that the mimics get lost or disappear due to an odd calibration configuration, the
process can be restarted by clicking the "Restore Defaults" button.
Advanced Calibration Parameters
The advanced calibration parameters allow the ground plane to be panned and rolled
without affecting the camera calibration parameters. This can be useful to visualize the
calibration setup if the scene has pan or roll with respect to the camera.
Note that the pan and roll advanced parameters only affect the orientation of the 3D ground
plane so that it can be more conveniently aligned with the video scene, and does not
actually affect the calibration parameters.
To use the advanced parameters click on the advanced parameters button. Drag the pan and
roll slider controls to change the pan and roll of the ground plane.
