I am writing a code for object detection and coordination finding in OpenCV. In windows, everything is done and the program is working wit no problem, but I need to move it to Linux and run OpenCV in Raspberry pi 3 and Linux Debian platform. I have tried many ways to install the OpenCV on Raspberry Pi and after long hours spending, I was not successful in loading te #inlcude files of OpenCV to use and also I cannot even define a "Mat" for loading an image.

I appreciate any help or tip to solve this issue.

Thanks

Have you installed the OpenCV development packages from the repository (usually suffixed with -dev )? Without knowing the specific components of OpenCV you are using, version or programming language, I am assuming you want to use the most common header files. You may need to include others depending on your requirements but the following is a basic guide.

From the terminal install the header files with:

$ sudo apt-get install libcv-dev libhighgui-dev

The current version in the repositories is 2.4. If using C++, the header files are included as an example:

#include <opencv2/core/core.hpp>
#include <opencv2/highgui/highgui.hpp>

In your code use the namespace using namespace cv; or prefix OpenCV objects with cv:: as in cv::Mat image; or cv::Point point;.

Again in C++ don't forget to add the following, usually at the end of your compile statement:

`pkg-config --cflags --libs opencv`

For example:

$ g++ test_opencv.cpp -o test_opencv `pkg-config --cflags --libs opencv`
  • How is your experience with the debian opencv package? I did build openCV 3.2 with cmake and neon optimization and believe this is the way to go, although it's some work to get all the prerequisites. – Philippos Apr 26 '17 at 6:09
