 Maximum detection height: Objects above this height are not detected;
 Minimum detection height: Objects below this height are not detected;

3. Calibrating Ground

After enabling the rule, set up corresponding parameters;
Select Calibration Config;
Take actions following the digital marks as above:
 Click Clear first
 Click Ground.
 As shown in the image, draw a large frame from the upper left to the lower right to cover the
ground in the visual field;
 Click Save, and the computation for calibration takes about 10s;
 Displays the camera height and angle. Make sure the displayed values are consistent with
the actual values;
Note: In ground calculation, select bare ground surface where there are textures (make sure
the ground is not too bright and thus reflective).
