I’m testing direction-detection function now. I wanna detect object’s 8 direction.
Please see below config :

direction-SE=96;1026;128;1058
direction-NW=96;1026;64;994
direction-SW=96;1026;64;1058
direction-NE=96;1026;128;994
direction-E=96;1026;128;1026
direction-W=96;1026;64;1026
direction-S=96;1026;96;1058
direction-N=96;1026;96;994

deepstream can’t detect 4 directions ( direction-SE, direction-NW, direction-SW, direction-NE ).
direction detection functions has a limit?
Why deepstream can’t detect 8 directions?

Could you update to the latest version 6.2 and try it? Theoretically, our latest version can support 8 directions.

6.0.1 support only 4 directions?

unfortunately, device cannot support deepstream 6.2.

You can just set 4 diretions, it can detect 8 directions according the angle.

Can you give a sample config file?
And How can I set 4 directions to detect 8 directions?

You can set the para like: direction-North-East=xxx;xxx;xxx;xxx. If an object travels in the same direction as paras you set, it will mark it on the text.

Thx for your reply.
But Deepstream 6.0.1 can detect only 4 directions. right ?
And Deepstream 6.2 can detect 8 directions? can I find that information at tech document ?

No. This algorithm has always existed that you can get directions by estimate the angle to the direction parameters you set.
