2017-03-16 04:27:22 -0600 | asked a question | upload GpuMat from memory pointer I want to upload a camera image to a GpuMat without unnecessary copy operations. I get the image as a naked char* from the camera API and at the moment convert it to a GpuMat approximately like this: Is this the "optimal" way to do it without copying data around? The CPU memory gets overwritten by the camera next time around, is this OK after I uploaded it to the GPU? Thanks! |
2016-11-29 08:33:06 -0600 | answered a question | non-aligned optical axis & effect on Stereo Calibration Bit late with my answer, but anyway: StereoCalibrate calculates the transforms necessary to create horizontally or vertically aligned images. If your horizontal setup has a (slight) vertical misalignment, you get rectified images which do not completely overlap vertically: from one image a bit from the top is cut of, from the other a bit from the bottom. As long as you have enough overlap for your application, the resulting stereo reconstruction should work fine, only with a reduced working volume. I am actually working with a ZED camera right now, which has a vertical difference of about 10 pixels of 720, and it works OK when calibrated. |
2016-09-15 09:13:05 -0600 | asked a question | Error in stereo_match.cpp example When I start the stereo match example in 3.1.0, I get an exception: in my opinion, the reason is the missing definition of the filenames in the CommandLineParser key string. In "stereo_match.cpp", instead of: it should read: Is this correct? Or am I missing something? |
