Verification Select a verification type, and then click Calibration Valid. To verify vertical ruler and horizontal ruler, respectively select Height Verification and Width Verification. Draw a straight line in the image to verify whether the rulers are correctly set. In case of big difference between the estimated value and the actual one, fine tune or reset parameters until the error requirement is met. 5.8.2 Rule Configuration Set rules for IVS, including cross fence detection, tripwire, cross region, abandoned object, moving object, fast moving, parking detection, crowd gathering, and loitering detection. For the functions and applications of the rules, see Table 5-6. Rule Cross fence Tripwire Intrusion Abandon ed object Moving object Fast moving Parking detection Table 5-6 Description of IVS functions Description Applicable Scene When the target crosses the set Road, airport, and other scenes with fence line from the defined direction, isolation zone. the system performs alarm linkage. When the target crosses tripwire from the defined motion direction, the system performs alarm linkage. When the target enters, leaves, or appears in the detection area, the Scenes with sparse targets and no occlusion among targets, such as perimeter protection of unattended area. system performs alarm linkage. When an object is abandoned in the Scenes with sparse targets and without detection area over the set time, the obvious and frequent light change. system performs alarm linkage. Simple scene in the detection area is recommended. Missed alarm omission might increase in the scenes with dense When an object is taken out of the targets, frequent occlusion, and detection area over the defined time, people staying. the system performs alarm linkage. In scenes with complex foreground and background, false alarm might be triggered for abandoned or missing object. Scene with sparse targets and less When the motion speed exceeds the occlusion. The camera should be defined speed to trigger alarms, the installed right above the monitoring system performs alarm linkage. area. The light direction should be vertical to the motion direction. When the target stays over the Road monitoring and traffic defined time, the system performs management. alarm linkage. Event 131
