2014-11-10 07:13:01 -0600 | asked a question | Camera calibration tutorial: assertion failed Hi, I am developing an algorithm which measures dimensions of an object. I noticed that measurement error rises when moving out of image center. So I decided to calibrate my camera. I came across this tutorial. The code I used is the same as in the tutorial AND in the openCV sample code directory (opencv\sources\samples\cpp\tutorial_code\calib3d\camera_calibration). The program finds all needed files - the configuration file, list of image names, images. So that is not the problem. When I run it, it throws an error:
The error seems to happen in the following statement: But it finds chessboard edges thou! Then I commented it and the error showed up a little later. The next thing I tried to create calibration all on my own. I wrote this program: } And again, same thing. All functions seem to work properly, finds corners, draws them on the image, shows them, only when I want to close window on waitKey(), the program throws same error again. I am very confused. Please help. Thank you! |
