Camera Installation (Object)
Install a camera so that an object to detect (human, cars, bikes, etc.) must not be overlapped with other objects.
- A camera should be installed so that an object does not tilt more than 30 degree.
- The size of the object on the image should be larger than 1/16th of the image size.
- The minimum size supported for reliable detection is 120 x 68 pixels or higher
(1920x1080 resolution)
1) If the object is a human
2) If the object is a car or a bike
The following conditions can reduce the accuracy of Line Crossing function.
• If the gap between the person in front and the person behind passing through the line is narrow. (same for
cars or bikes)
• High density crowds in which objects pass both inside and outside of the line
• The environment in which objects stay or loiter near the line.
