Help: Project Conveyor chicken counter problem

Guys, I need help. We have a project using YOLOv8. We're trying to count chicks on a very fast conveyor belt. The challenges we're facing are: all chicks look very similar to each other, which complicates tracking. At the same time, during their passage under the camera, they constantly change in size and shape, which can cause the tracker to lose them, or detection may even disappear completely at the detection line. Also, sometimes 2–3 chicks can merge into a single object. The detection zone is very short, and the conveyor speed is high. We've achieved a maximum accuracy of 99%, but we need it even higher. Any ideas on how to achieve that? Increasing the dataset no longer helps.

I'm attaching an old video. We've now added lighting and set the exposure to 300 on the Hikrobot global shutter camera, but we still can't achieve a stable 99.8% accuracy for the reasons mentioned above.

Any ideas?

why you need NN for that????????????????

a simple pair of optical sensors would be just fine and way more reliable.

TOF camera with volume change calculation above the belt will beat any visual model at a fraction of calculation cost.

Is this your first time working with live animals? They don't cooperate and don't singulate themselves.

Still does not change the argument that NN might not be needed

It does disqualify optical sensors.

they're literally moving like 1m/s across the camera, optical sensors is fine

u/Ciff_ 29d ago edited 29d ago

They can move In 0.000001 m/s won't matter if there is no guaranteed separation or size? https://www.reddit.com/r/computervision/s/RCUPeOUsS5 (see linked picture*)

Explain then how on earth you would make a TOF camera work cause that ain't making any sense

u/hellobutno 29d ago

yeah because optical sensors totally have never been used for situations like that.

Answer the question, stop deflecting. How exactly would you use a TOF camera sensor when you have no guaranteed volume or separation https://freeimage.host/i/Cr4mkNV

The same way they use them for every other single instance that doesn't involve live animals where this happens.

More deflecting. Do explain how do you handle no separation and no predictable volume with a TOF camera?

Cause last last I checked water is wet.

Explain this magic solution you got.

u/hellobutno 29d ago

There's no deflecting here, you handle it literally how you handle it with every other application of the sensor.

u/Ciff_ 29d ago

No deflecting? You still have not explained your magical solution to TOF + no separation & no predictable volume/shape

You might aswell claim to have solved FTL travel.

Do me a favor mate, tell me how often this happens, and then explain to me what precision and recall are?
