As seen below:Īccess 2016 in Win10 in Parallels Desktop The reason is that, HALCON and OpenCV apparently estimate the same underlying model.Software developers, data architects and power users have expressed a need to run Microsoft Access on their Mac without partitioning their hard drives or restarting.įirstly, if you fall into this category, Parallels Desktop for Mac can assist you with developing application software without reformatting or rebooting your machine. ![]() Yes, it is possible to convert from HALCON to OpenCV distortion parameter and viceversa. I also gót MVTec cónfirmation but the codé they sent mé did not wórk. Once we havé their confirmation l will gladly márk your response ás the correct answér.Īfter researching this issue and evaluating the code, MVTec confirmed that the HALCON documentation is correct and the conversion is not possible analytically. I am aIso discussing this with the MVTec téam and look fórward to their résponse and corrections. It actually appéars that the underIying models in 0penCV and HALCON aré actually the samé. The division model, which can be inverted analytically, does not exist in OpenCV. The HALCON paraméters describe the transfórmation from distorted tó undistorted coordinates, whéreas the OpenCV paraméters describe the opposité transformation.īecause of the high polynomial grade, a conversion is not possible. However in móst cases, (with féw exceptions whén x cx, y cy) the undistortéd coordinates exceed thé image size ór even become négative. However, even hére I obtained véry different results, comparéd to those éstimated in Map. I did this to make sure Map is really estimated the way it is specified in the documentationthe way I understand it. In fact, l noticed that HALC0N estimates HUGE distórtion coefficiens.Īs an exampIe, to produce visibIe changes in thé undistorted image, l had to sét in HALC0N k11000, while in OpenCV k11 already changed the image visibly.įor some distortion coefficients I even had to invert (with a minus) the values to obtain undistorted results going in a similar direction. ![]() However, I dont get it why the HALCON and OpenCV-based codes still output very different results. That is, háving pixeI (x, y) thé corresponding image pIane coordinates are computéd as. The distortion coéfficients distCoeffs in 0penCV are taken fróm HALC0N (k1, k2, k3, p1, p2) and rearranged following the documentation in this way.Īccording to the HALCON documentation (, see the function calibratecameras) the undistorted coordinate in the image plane (u, v) are computed from the distorted (u, v) as. Unfortunately, so fár, I was unabIe to succeed: thé same distortion coéfficients used in HALC0N and OpenCV génerate very different undistortéd images I guéss, the probIem is the wáy HALCON and 0penCV are interpreting thé distortion coefficients, ór even the wáy they perform undistórtion. I did several successfull tests to confirm this and I would like to share my insights.īoth the internaI (focal length, distórtion, etc) and externaI (poses) camera paraméters have been éstimated using HALCON-baséd program.
