| 2013-01-03 14:18:04 -0600 | asked a question | Webcam incompatible with OpenCV? Insufficient buffer memory error for device I have a usb camera that I am using for robotics related development purposes. I am using Ubuntu Linux. The webcam works fine with Cheese webcam capture, mplayer, v4l, ffmpeg, etc - I can capture images, videos, etc. However, when I try and capture image or video using OpenCV, I get the following runtime error:
Why would the camera not work with OpenCV? I tested the same OpenCV program with a different USB webcam and it works fine, it is just this webcam that is having problems with OpenCV. Is there any way I can get around this error? |
| 2012-10-03 12:15:10 -0600 | asked a question | OpenCV stitcher transform Dear OpenCV users, I have used the stitcher routine to stitch a set (SetA) of 6 images together to create a panorama. Now, I would like to stitch another set (SetB) of 6 images together, but with the same transform as applied to SetA. SetA are 8bit PGM images. SetB images are of different RGB values, and are not 8bit, but 16bit. I just want to stitch them together so I know that pixel (u,v) from setA matches to pixel (u,v) of setB. How can I do this? |

| 2012-10-02 13:20:20 -0600 | asked a question | Pixel to pixel mapping for stitcher routine? Dear OpenCV users, I have implemented OpenCV's stitcher() routine using C++. Let's say I have a set of 5 images, and they are all stitched together to create a panoramic image. How can I get the mapping of pixel (ap,bp) in the panoramic image to it's parent image (1 or 2 or 3 or 4 or 5) pixel (an,bn)? I see that the stitcher routine outputs Initial intrinsic parameters, and Camera parameters. But I do not understand those parameters |
