Usage:tesseract imagename outputbase [-l lang] [-psm pagesegmode] [configfile...]

pagesegmode values are:

0 = Orientation and script detection (OSD) only.

1 = Automatic page segmentation with OSD.

2 = Automatic page segmentation, but no OSD, or OCR

3 = Fully automatic page segmentation, but no OSD. (Default)

4 = Assume a single column of text of variable sizes.

5 = Assume a single uniform block of vertically aligned text.

6 = Assume a single uniform block of text.

7 = Treat the image as a single text line.

8 = Treat the image as a single word.

9 = Treat the image as a single word in a circle.

10 = Treat the image as a single character.

-l lang and/or -psm pagesegmode must occur before anyconfigfile.

tesseract imagename outputbase [-l lang] [-psm pagesegmode] [configfile...]

tesseract 图片名 输出文件名 -l 字库文件 -psm pagesegmode 配置文件

例如：

tesseract code.jpg result -l chi_sim -psm 7 nobatch

-l chi_sim 表示用简体中文字库(需要下载中文字库文件，解压后，存放到tessdata目录下去,字库文件扩展名为 .raineddata 简体中文字库文件名为: chi_sim.traineddata)

-psm 7 表示告诉tesseract code.jpg图片是一行文本 这个参数可以减少识别错误率. 默认为 3

configfile 参数值为tessdata\configs 和 tessdata\tessconfigs 目录下的文件名
