在linux环境下 编译opencv (C++）工程

工程目录如图所示

首先需要编译生成三个.o结尾的文件

执行以下三个编译命令

 g++ -c CalculateStem.cpp  -o CalculateStem.o -I/usr/local/include/ -lraspicam -lraspicam_cv -lopencv_core -lopencv_highgui  -lopencv_imgcodecs

 g++ -c Curvefit.cpp  -o Curvefit.o -I/usr/local/include/ -lraspicam -lraspicam_cv -lopencv_core -lopencv_highgui  -lopencv_imgcodecs

 g++ -c ExtractCenterLine.cpp  -o ExtractCenterLine.o -I/usr/local/include/ -lraspicam -lraspicam_cv -lopencv_core -lopencv_highgui  -lopencv_imgcodecs

最后生成program 执行文件
 g++ CalculateStem.o  Curvefit.o  ExtractCenterLine.o -o  program  -I/usr/local/include/ -lraspicam -lraspicam_cv -lopencv_core -lopencv_highgui -lopencv_imgcodecs -lopencv_imgproc

使用

./program   命令执行改文件
