객체 추적기 구성에 대한 권장 사항

To avoid false positives of Scene Analytics detection tools, please follow the recommendations here:

1. Configure the Tracker object object iteratively and check operation quality in each iteration.
2. The parameters that affect operation quality most are: Minimum size, Maximum size (see 검출을 위한 최소 및 최대 객체 크기 설정), and Sensitivity (see 추적기 기반 장면 분석 검출 도구의 일반 매개변수 설정).
3. It is recommended to use Auto sensitivity mode to ensure quality of the Tracker operation in changing lighting conditions.
4. If lighting is stable, it could be reasonable to adjust the Sensitivity value manually. Set Sensitivity value about 35 to detect objects with low contrast or about 15 to detect contrast object.
5. Minimum size is to be selected so that it is a little less than typical object size on the image.
6. Maximum size is to be selected so that it is a little greater than typical object size on the image, considering that the object can be joined with its shadow.
7. Lowering the Time of Object in DB allows excluding triggering of false static objects, while setting it to a higher value could allow not breaking off alarms for overlapping or temporarily disappearing objects in some cases.
