When using the PinholeCameraModel class, I'm getting the following
runtime error:

OpenCV Error: Assertion failed (src.isContinuous() && src.depth() ==
CV_32F && ((src.rows == 1 && src.channels() == 2) ||
src.cols*src.channels() == 2)) in undistortPoints, file
/home/dfseifer/ros/stacks/vision_opencv/opencv2/build/opencv-svn/src/cv/cvundistort.cpp,
line 383

with the following code:

cv::Point2d uv;
uv.x = b.x; uv.y = b.y; //valid image coords
cv::Point2d uvrect;
pcam_.rectifyPoint( uv, uvrect );

I made this error go away when I changed the rectifyPoint section to
the following:

const cv::Mat src_pt(1, 1, CV_32FC2, const_cast<double*>(&uv_raw.x));
cv::Mat dst_pt(1, 1, CV_32FC2, &uv_rect.x);
cv::undistortPoints(src_pt, dst_pt, K_, D_, R_, P_);

where CV_32FC2 used to be CV_64FC2

I am using box_turtle release (updated today) with Ubuntu 10.04.

My question is, was this a bug in the image_geometry package, or was
my code wrong?

Thanks as always,
-Dave
