Recognizer configuration on CentOS
I usually forget some things.
Today, I reinstall my centos system and configure recognizer on it (Recognizer is my online version demo, powered by OpenSSE v1.10. You can get an offline version on my Github). This work actually took me two hours, it’s unbearable thing! So, I decide to record.
Until now, OpenSSE only dependent on OpenCV and boost (Core engine has canceled Qt library in new version). We start from OpenCV.
- Install all the required packages using yum
yum groupinstall "Development Tools" yum install gcc yum install cmake yum install git yum install gtk2-devel yum install pkgconfig yum install numpy yum install ffmpeg
- Create working directory and check out the source code
mkdir /opt/working cd /opt/working git clone https://github.com/Itseez/opencv.git cd opencv git checkout tags/18.104.22.168
You can chooce any OpenCV version not less than 2.4.
- Create the Makefile
mkdir release cd release cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local ..
- Build and install
cd /opt/working/opencv/release make make install
- Add OpenCV to system
cd /etc/ld.so.conf.d/ echo "/usr/local/lib/" > opencv.conf sudo ldconfig
wget http://sourceforge.net/projects/boost/files/boost/1.55.0/boost_1_55_0.tar.gz tar -zxvf boost_1_55_0.tar.gz ./bootstrap.sh --prefix=/usr/local ./b2 install --with=all
cd opensse/src mkdir build cd build cmake .. make make install
Recognizer (OpenSSE online version) build
Make sure database has a correct path before build recognizer(
recognize.cpp), and then
mkdir /tmp/opensse-tmp/ to cache temp image.
Run web api, everything is going well, Do you want to try?
