2017-01-05 07:39:11 -0600 | asked a question | False memory leaks in MFC Is there someone who uses OpenCV in the MFC application? I don't believe that I am the only person on the world who is using this combination. I have really annoying problem with false memory leaks. It is impossible to detect any real memory leak because false memory leak report is huge. I tried everything what I found on the internet but nothing works. I tried:
Nothing works. Still the same result. I'm out of ideas what to try. It is impossible to debug my application with these false memory leaks. Please, Is there someone who is using Opencv and MFC without problem? For example: Code: Result: |

2016-12-05 12:20:35 -0600 | asked a question | Asymmetric Circles Grid - large images problem Hi, I'm trying to calibrate a camera with Asymmetric Circles Grid. It works fine but only for very small images like 640x480. I need to calibrate with much bigger images but findCirclesGrid function cannot detect large circles. I found the problem is probably in SimpleBlobDetector settings. When I'm increased maxArea parameter to 50000. It's able to detect some of my source images but only those with ideally rounded circles. Images with perspective deformed circles aren't detected. How I must set other Blob detector parameters? Or the problem is elsewhere? Example: Detected small image, Not detected large image Edit: It seems that CALIB_CB_CLUSTERING flag solved my problem. |

2016-12-01 10:52:08 -0600 | asked a question | Calibrate camera - reprojection error Hi I'm trying to calibrate a camera for undistort and pose estimation. What is acceptable value of reprojection error? The best value I got is around 3 for 30 source images. When I use more images, like 70 or 100, the reprojection error is more than twice bigger and pose estimation is very inaccurate. |

2016-11-04 05:17:33 -0600 | asked a question | Weird memory leaks in MFC I have a problem with weird memory leaks. When I create simple MFC Dialog based application and add some Opencv code I get memory leaks warning even the OpenCV code is never executed. (OpenCV 3.1, VS11) I have added only this: And the result is: The code inside OnBnClickedButton1 function is never executed but it causing memory leaks. When I remove this code, it's ok without any memory leaks. I tried everything. Shared DLLs, Static libs, but still the same result. Maybe I forgot some settings, because I build OpenCV by myself. |
