How to convert cv::Mat to rs2::frame ?

yliu54 — Tue, 23 Oct 2018 13:59:34 GMT

hello,

I have already seen this question in this community but didn't get the answer I want.

In rs_align, I have converted the rs2:: frame to cv:: Mat for using the joint bilateral filter provided by OpenCV to improve the quality of the depth map. The depth map of the processed mat type that is obtained cannot be used to call remove_background（）.

So,I just want to know how to convert cv:: Mat to rs2:: frame. If you can help me, I would be very grateful.

Thank you!

Intel support team member Eliza has stated on a past reply to this question in September 2018, "The memory in rs2::frame may be reused by librealsense/UVC. Converting from cv::Mat to rs2::frame (copy pixel array to a object of rs2::frame) is not a good idea. Note that when the camera captures images, the uvcvideo driver writes the frame information into the rs2::frame".

Thank you for your reply!

But in order to use cv::ximgproc:: jointBilateralFilter,I have converted rs2::frame to cv:: mat.I just want to transform the destination filtered depth map(rs:: mat) to rs:: frame for using the remove_background().

I do not know how to do such a conversion, unfortunately. Hopefully one of the Intel support team on this forum can provide some advice on this. Good luck!
