OpenCV + Zybo + SDSoC + linux

[RaulRB]

Hi friends,

I am trying to make an app with opencv in SDSoC but it isn`t working.

The code that i am using is this ( simple code to do a simple hello world):

#ifdef USE_OPENCV
#include <opencv2/opencv.hpp>
#endif

#include <iostream>

using namespace std;

#ifdef USE_OPENCV
using namespace cv;
#endif

int main() {

    #ifdef USE_OPENCV
    Mat im,gris;
    im = imread("lena.jpg");
    cvtColor(im, gris, COLOR_RGB2GRAY);
    imwrite("Gris.jpg",gris);
    waitKey(0);
    #endif

    return 0;

}

 

If i don't use de ifdefs it  has few problems like this:

Can you help me please?

Thanks,

Hi Raul,

Unfortunately I do not have much experience with SDSOC. Hopefully some of the more experienced community members can better help you. I have found some documentation that might help. Here and here are xilinx's SDSOC page. Here is a xilinx forum question dealing with SDSOC 2016.2 and OpenCV. 

thank you,

Jon

Thanks for the response Jon,

In fact I had been revised this link's few days ago.

The link from the Xilinx forum has examples for the zc702. I downloaded the example and compile in SDSoC, but I don't have this board and can't try it. The example uses the " ifdef opencv " sections for the opencv code. But I don't know if it works

I wrote the rest of the history in my previous post.

Regards,

Raúl
