Fixed Camera, Object ID change when occluded by a big object

[AhmedKhaled945]

Hello, i have a fixed camera with traffic feed, and one class of objects I have in this feed is vehicles, detection works really good, tracking is reasonable but for some cases, when a vehicle or an object is occluded with a very big object (like a bus for example), it disappears for 10-15 frames and then come back to view, with a different id,

tried to increase the value of track buffer to 30 frames, even 60, but nothing changed, still the same object is assigned with different id when it passes the big object,

Is there anything that can be done to prevent that?

Thanks in advance, @ifzhang

I am similar, the id changes when a person is completely covered by a person in front for about a dozen frames

@AhmedKhaled945 I think the only one for solving this issue using Re-id, but you will another problem is you have some vehicle are same, but you can use the topology of traffic you can earn a lot of information from it.
