Can you have demo which detects and recognize numbers(5,6 or 7 digits on object) from camera?
I have some objects in which numbers is drawed and I want to recognize numbers in object when they moving from camera?

Thank you

Thanks.

IEVision uses OpenCV for object detection and Tesseract for OCR.

The problem here is that there is a lot going on in the image, so if you OCR the whole thing it will be:
- slow
- lots of false data

This is the OCR of the whole image:

R |
# %7 k \\\
B . S \,
B2 & P
y } L -
s -
Yt
(15498 B s -
- /[b ~ V
" V \:\
e
S h 3 B
"
N
AN
L
SHOT ON MI 9T
| LOJO RN


This is when selecting the text:

15498


There does not seem to be a good way here to automatically determine what needs to be OCR'ed to improve the process.

The other issue is orientation. Tesseract does not work well with text that is short and significantly rotated.

So, I'm afraid I don't have any good suggestions for you here.

Hi

Can you attach an image showing the type of numbers you are talking about?
