！！！官网编译教程！！！建议完整看完后再作操作。

https://github.com/tesseract-ocr/tesseract/wiki/Compiling#linux

1）必要流程

If they are not already installed, you need the following libraries (Ubuntu 16.04/14.04)

sudo apt-get install g++ # or clang++ (presumably)sudo apt-get install autoconf automake libtoolsudo apt-get install autoconf-archivesudo apt-get install pkg-configsudo apt-get install libpng12-devsudo apt-get install libjpeg8-devsudo apt-get install libtiff5-devsudo apt-get install zlib1g-dev

if you plan to install the training tools, you also need the following libraries:

sudo apt-get install libicu-devsudo apt-get install libpango1.0-devsudo apt-get install libcairo2-dev

2）leptonica编译（有2种方式，一种是github源码，一种是压缩包，我使用github源码）

sudo apt install gitgit clone https://github.com/DanBloomberg/leptonica cd leptonicaautoreconf -vi./autobuild./configuremake 

sudo make install

3）安装tesseract

cdgit clone --depth 1 https://github.com/tesseract-ocr/tesseract.gitcd tesseract./autogen.sh./configure --enable-debugLDFLAGS="-L/usr/local/lib" CFLAGS="-I/usr/local/include" makesudo make installsudo ldconfig

tesseract -v

测试效果如下图

4）安装训练文件

makemake trainingsudo make training-install

5）安装调试工具
下载官方的两个jar包，复制piccolo2d-core-3.0.jar and piccolo2d-extras-3.0.jar 到 tesseract/java文件夹下，网址：https://github.com/tesseract-ocr/tesseract/wiki/ViewerDebugging

sudo apt-get install default-jresudo apt-get install default-jdkcd tesseractcd javamake ScrollView.jarexport SCROLLVIEW_PATH=$PWD

在/tesseract/api/tesseractmain.cpp找到如下代码

插入以下代码

api.SetVariable("tessedit_dump_pageseg_images", "true");    api.SetVariable("textord_show_blobs", "true"); api.SetVariable("textord_show_boxes", "true");  api.SetVariable("textord_tabfind_show_blocks", "true");api.SetVariable("textord_tabfind_show_reject_blobs", "true");   api.SetVariable("textord_tabfind_show_initial_partitions", "true"); api.SetVariable("textord_tabfind_show_partitions", "1");    api.SetVariable("textord_tabfind_show_initialtabs", "true");    api.SetVariable("textord_tabfind_show_finaltabs", "true");  api.SetVariable("textord_tabfind_show_images", "true"); 

变成

保存。

cd tesseractmakesudo make installsudo ldconfig

6）下载语言包

我选择了tessdata

git clone https://github.com/tesseract-ocr/tessdataexport TESSDATA_PREFIX=/home/XX/tessdata

7）测试

tesseract rorate.png out -l chi_sim+eng

8)测试2

tesseract /home/joy/tesseract/testing/phototest.tif

关掉一个窗口，就跳出来了！

！！！！终于出现官网的图片了！

插入翻译：

The words found in the image are represented as blue rectangles. There are 3 menus:

MODES sets the mode for what a left-click or selection does. DISPLAY changes the requested displayed content of the window. (Not immediately) OTHER provides a bunch of miscellaneous global actions. If you right-click in the Editor Image window, you can change the values of any of the "new" config variables on the fly. Depending on what you want to change though, a lot of the useful variables are in the old style and cannot be changed this way. Some day, someone will update all the old style variables to new ones.

NOTE that the menus seem rather strange. This is because the tool was originally designed to provide the capability to create ground truthed files, in excruciating detail with labels on the characters, information on the connected components making up each character etc. Most of this functionality is redundant and hasn't been used in over 10 years. Some of the functionality advertised can easily crash the program, but the functionality documented here should work...

To show the characters, deselect DISPLAY/Bounding Boxes, select DISPLAY/Polygonal Approx and then select OTHER/Uniform display.

To zoom in, position the cursor over a word, and roll the mouse scroll wheel away from you 2 or three clicks. Each click doubles the size. To zoom out roll the mouse wheel towards you. If you haven't got a mouse wheel ... you may be out of luck. The Java code needs some work in this area.

Now select MODES/Recog words and click in a word. If you choose the word 'code' (the 2nd word on the 2nd line) then you should get something like this:
