tesseract4.0：ubuntu16.04 +x64+leptonica1.74.4源码安装（ViewerDebugging）工具记录

！！！tesseract官网有提供相关视频！！！

https://www.youtube.com/watch?v=vOdnt2h1U8U https://www.youtube.com/watch?v=WZLJucXZy-g ！！！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#linux1）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 libtool
sudo apt-get install autoconf-archive
sudo apt-get install pkg-config
sudo apt-get install libpng12-dev
sudo apt-get install libjpeg8-dev
sudo apt-get install libtiff5-dev
sudo apt-get install zlib1g-dev

if you plan to install the training tools, you also need the following libraries:
sudo apt-get install libicu-dev
sudo apt-get install libpango1.0-dev
sudo 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 git
git clone https://github.com/DanBloomberg/leptonica cd leptonica
autoreconf -vi
./autobuild
./configure
make

sudo make install

3）安装tesseractcd
git clone --depth 1 https://github.com/tesseract-ocr/tesseract.git cd tesseract
./autogen.sh
./configure --enable-debug
LDFLAGS="-L/usr/local/lib" CFLAGS="-I/usr/local/include" make
sudo make install
sudo ldconfig

tesseract -v

测试效果如下图


4）安装训练文件
make
make training
sudo make training-install5）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/ViewerDebuggingsudo apt-get install default-jre
sudo apt-get install default-jdk
cd tesseract
cd java
make ScrollView.jar
export 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 tesseract
make
sudo make install
sudo ldconfig

6）下载语言包我选择了tessdata

git clone https://github.com/tesseract-ocr/tessdata export 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:

!!!Do not install 

libleptonica-dev

 with apt-get, since you manually intsall leptonica later.
