Step 2: Adjust tilt angle and camera height
Now, adjust the camera tilt angle and vertical field of view until both mimics are
approximately the same size as a real person at that position in the scene. If an estimated
height is entered then adjust this along with the other two parameters.
Click and drag the ground plane to change the tilt angle, use the mouse wheel to adjust the
camera height and enter the value in Vertical Field of View edit box to change the vertical
field of view.
Apply the changes:
Once the changes have been applied, the Calibration Status reflects whether the operation
was successful, and if so, in which mode the camera is calibrated.
Step 3: Verify the setup
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.
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 Measurement Units Topic.
