Hello, I have an issue with a deepstream - nvdsanatics’ line crossing feature.
For objects and lines that are far away(where y coordinate is small) and moving slowly(there is little change in bbox coordinates), “line crossing” does not count them even when they passed the line.
The track id of the object does not change, and it seems that its bottom center coordinate passes the line in the right direction.
However, when objects are moving relatively fast, they are counted properly even on the lines far beyond.
We do not see any miscount when lines are close.
- Does line crossing is affected by the slow movement of the bbox.
- If correct, is there a way for us to customize the line crossing function?
Below is the analytics config file used.
