Opencv Error Assertion Failed (s = 0) In Setsize

wongjustin99 commented Dec 12, 2012 @kylemcdonald Hi there, thanks for getting back to me. AKA, I don't really know the exact problem. I got this error when I tried to fill it by making a single vector of 3D points accurate, then duplicating that vector once within objectPoints for each image I had.

Let us know if so! Magic popcount numbers Is space piracy orbitally practical? This is I believe what is meant by the "scn == 3" thing….somehow saying the source doesn't have at least 3 color channels.

Here's the OUTPUT of the compile. How would tampering with voter registration rolls be detected?

The check seems to be getting called on my objectPoints vector…but according to the for loop it is called from it should always fail. Have you done plenty of assumption checking? You signed out in another tab or window. Print things out in different ways, make sure to print them out just before the calibrateCamera call, etc.

It's likely not your object or image points. Your cache administrator is webmaster. What "actually" happens at T-minus-0 Does this use of std::make_unique lead to non-unique pointers? Pas de panique, on va vous aider !

Right now, the config data is stored between ~/.uWho and ~/.config/JoshConwaySoft/ I would prefer everything be stored in a single directory, preferrably ~/.uWho . When attempting to calibrate a stereo camera pair, I was having the oddest issue: running on my professor's test images, I got imperfect but decent results.

You saved me many hours of stupid trial and error. Check This Out Reload to refresh your session. Terms Privacy Security Status Help You can't perform that action at this time. I just had to fix this pathname so that the source Mat was a valid (non-empty) Mat.

  • Fix: In my case, this meant that, like the destination Mat, the source Mat was empty…I had written a wrong pathname to get the image data I wanted to undistort.
  • Everything works fine till final calibrateCamera function call…..

  • I believe nimages is "number of images," so the assertion is failing because there isn't a greater-than-zero number of images to calibrate.

I'm new to qt creator and I'm stuck at how to change the paths for these std::string face_file = (QDir::homePath() + QString("/.uWho/face.xml")).toUtf8().constData(); QFile face(QDir::homePath() + QString("/.uWho/face.xml") ); QDir uWhoconfig( QDir::homePath() + That's the worst. Collaborator kylemcdonald commented Aug 12, 2012 i see, it's probably a bug with how i've wrapped the image loading, or somewhere i should be reallocating but i'm not.

You mentioned your rvecs and tvecs are of the right type; are they properly filled?

Let me know if you figure it out.

First of all, shouldn't I be seeing a total of 12 lines of printout? Incredibly. We recommend upgrading to the latest Safari, Google Chrome, or Firefox. I eventually discovered that, for whatever reason, the chessboard corners on my images were being found in the opposite direction from the ones on the sample images.

You could pass us your code and I could take a look at it, maybe some other people who have commented might see it and be able to help. I ought to write up some hints on how I got this to happen in the first place, as well…getting OpenCV working with Xcode isn't really trivial. Usage of wish for expressing regret Idiom/expression that means "to suddenly tell some news" to someone? The Detect Thoughts spell is trivializing social encounters.

I don't really remember why that conversion is necessary. I'm guessing you're sanity checking each factor by printing out values at run time? I am not sure if I still might be missing something to check at assertion part .
