Your decimal point is not well resolved. The ocr() documentation says you should have 20 lines of image data to get a good prediction. Attach your gray scale or binary image if you need more help.

yes,sir,may be make some image process,such as im2bw、imbinary,and use the ocr number parameter,such as
ocr(bwt,'CharacterSet','0123456789');

Looks like you excluded the decimal point from your character set. I think that would need to be included. That is the character that he wants to find and it's having trouble detecting.
