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');

may be upload image to do some analysis

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.
