You can set the minimum and maximum object size for detection by specifying numerical values or reference areas on screen. Objects of all sizes beyond the set values will not trigger detection.
To specify the size, do as follows:
In the Max. object height and Max. object width fields (1), enter the maximum height and width of a detectable object as a percent of the FOV height. The values should be in the range [0,05; 100].
Attention!
If you activate the Object calibration parameter in tracker settings, please note that in this case min/max size of objects is specified in decimeters, not in FOV percentage (see Configure Perspective).
To set the reference area on screen, do as follows:
Click the min button and set the minimum size of a detectable object. You can do so by dragging and dropping the nodes of the reference area.
Note
For your convenience, you can click the button and configure the mask on a still frame/snapshot. To undo, click this button again.
Click the max button and set the maximum size of a detectable object.
Note
By default, the maximum size is the whole size of FOV, so the nodes are located in the corners.
You have successfully set the minimum and maximum object size for detection.
Note
These settings will apply for all Scene Analytics detection tools on the selected camera.
