在Raspberry PI上运行OpenCV

Question

I am trying to test a simple example program on Raspberry PI, to start test OpenCV function on Raspberry PI.

After successful compilation, I get an empty window.

The code is an example code when could be found on the OpenCV website, however the only part I change is name of the picture.

IplImage* img = cvLoadImage("pic1.jpg", 3);

All I get in an empty window. The pic.jpg is saved in the home directory (home/pi) .

Anyone came across this before?

Regards

Answer 1

Make sure object file and jpg that you're trying to load is in the same directory. (home)

Or just use complete path like this.

IplImage* img = cvLoadImage("/home/pi/pic1.jpg", 3);

Hope it helps.
