How to convert T265 fisheye frame data to opencv cv::Mat?

[SJhav]

Hi I want to do some image processing on the image captured from the T265 in openCV but for some reason it's not converting properly and when I do the imshow, it is just a blank a screen.

The active profile shows that fisheye is a Y8 based camera so I have used CV_8UC1 as the type in conversion but I suspect that I am missing something silly here.

rs2::frameset data = pipe.wait_for_frames(); rs2::frame fisheye = data.get_fisheye_frame(); cv::Mat fisheye_mat = Mat(Size(500, 500), CV_8UC1, (void *)fisheye.get_data(), Mat::AUTO_STEP); imshow("T265", fisheye_mat);

Thank you.

Hello SJhav,

Thank you for your interest in the Intel RealSense T265 camera.

Could you please let us know if you have checked the Imshow example? https://github.com/IntelRealSense/librealsense/blob/master/wrappers/opencv/imshow/rs-imshow.cpp

Thank you,

Eliza

Hey Eliza,

Thanks for replying me.

Yes I have tried it and it is not working. One of the reason being is the type used in there is CV_8UC3 but the fisheye_frame is gray single byte size image so it is not working.

Best,
