i using asp.net 4.0 , mvc 2.0 web application. project requiremrnt have use server side control in application not possibl in noraml case. ideally want use adrotator control , datalist control. i saw few samples , references in codepleax mvc controllib howwver found less useful. can tell how utilize theese controls in asp.net application along mvc. note: please provide functionalities related adrotator , datalist controls not equivalent functionalities thanks in advace. mvc pages not use normal .net solution makes use of normal .net components impossible. a normal .net page use event driven solution call different methods service side mvc use actions , view completly different way handle things. also, mvc not use viewstate normal .net controlls require. found article discussing mixing of normal .net , mvc.

c++ - OpenCV: wrap image to cylindrical coordinates -

-

i'm trying create panoramic image using opencv library. based on this, need warp image cylindrical coordinates. got formula convert 3d cartesian (x,y,z) cylindrical coordinate(θ,v) panoramic image mosaic paper , is:

  θ = tan−1 (x/z)    v = y/ √ (x^2 + z^2)

i have read opencv mailing list thread cylindrical image warping, based on paper, don't think need use camera calibration matrix. and, in website, problem has not been solved. th question is, how can convert opencv iplimage cylindrical coordinate , display them correctly?

thanks in advance.

unfortunately, need camera calibration if wish warp image cartesian cylindrical coordinates.

think it. if camera not calibrated, not know field of view of camera. if not field of view, can not map pixels optical rays. if not know optical ray corresponds pixel, there's no way express pixel in cylindrical coordinates.
