OCR performance with a conveyor belt.

RyanLee

Could you explain some more detail about below sentence? what looks like and side effect for OCR function?
" but the OV9782 is global shutter, which might lead to images not being warped a bit."

Best regards,
Ryan.

Hi RyanLee ,
See the effect of moving object when using rolling shutter camera:

With global shutter, we don't have this warp effect (we still have motion blur at long exposures though).
Thanks, Erik

Hi Erik, Thank you for your information.
We have one more question. we are considering using your OAK-D-Pro W(global shutter, OV9782). Could we change its focusing distance after we received from you? or Can we ask you its customerized focusing distance if we need? We would like to have its best auto focusing performance as much as we can. And we hope to know the best way of focusing for moving objects (boxes) and its size will be diffent as well.

Best regards,
Ryan.

Hi RyanLee ,
No, CCMs lens are glued in place, so you would likely break the lens before being able to move it. Yes, for larger batches we can customize CCMs, please send email to sales@luxonis.com. Note that these are fixed focus, not auto-focus.
Thanks, Erik

Hi erik

I hope to cross-check one more. Ok we got the hardware point of view and we have one more queston with software point of view. are there any way to change its focus using software? runtime or during the boot?

Best regards,
Ryan.

erik

Hi RyanLee ,
Yes, if the camera is AutoFocus you can change the focus either in runtime (demo here) or during the boot;

camRgb = pipeline.createColorCamera()
camRgb.initialControl.setManualFocus(123) # 0..255

Thanks, Erik

RyanLee

erik That mean that it is not possible to change its focus with OAK-D-Pro W(OV9782). Because it is fixed focus. Am I right? I just hope to cross-check about it once more.

Best regards,
Ryan.

erik

RyanLee Yes, you are right.

Just wanted to say hi. It was pretty cool seeing the Korean waybill in this forum. Seems Luxonis camera is already going global haha.

RyanLee

GeonsooKim I think so. it is already globa. Would you mind asking you which application you are in now? Anyway nice to meet you.

Best regards,
