Yeah you are right good catch, my correction is wrong. There is indeed an additional typo on the tl.y >= im_grey.cols check that should be tl.y >= im_grey.rows But I'm still not sure the -1 is enough because in the next lines there is a im_grey.at<uchar>(tl.y+1,tl.x+1) which will be out of bounds because if tl.y == im_grey.rows -1 then tl.y + 1 = im_greys.rows.

Ah, I was ignoring this error putting the tracker in a try catch block. I finally decided to look into it this week. Found a solution and came here to put in a bug report and found that you beet me to the punch :) Anyways I'm curious if -2 is the proper solution. for myself I was changing the check for tl.y to be on the rows rather than the columns. if(tl.y>=im_grey.cols)tl.y=im_grey.rows-1 to if(tl.y>=im_grey.rows)tl.y=im_grey.rows-1 This fix makes sense to me. My rows and columns are different...

I was also getting the same error. I updated my opencv to version 4.5.4 and tried again and it was built successfully.

Hi ! Your CPU/Computer mostly affect the processing speed. The pose accuracy is mostly affected by the camera hardware, in particular its resolution (the bigger the better) in comparison to its field of view, as well as the marker distance from the camera (the further away the marker, the more imprecision increases). (And of course the algorithms, but let's consider the ArUco one here). For the choice of camera/CPU, it depends on your goal. The bigger the resolution, the more processing is needed,...

DM_VIDEO_FAST cornerUpsample-Bug and Workaround
-
Hello Robert, It seems like my bug in DM_VIDEO_FAST originates in the "Autosize" feature. Changing the "params.ts" value altering the MinMarkerSize that is used by the implementation of the markerdetector. This breaks the Resize or the ImagePyramid feature resulting in an error in the ID detection even though the contours are detected correctly (as far as i can tell). If you are having troubles with DM_FAST the only change from DM_NORMAL is the ThresholdMethod. markerdetector.cpp line 384-394: "...

Hello Robert, i also want to use the Library for the DM_FAST and the DM_VIDEO_FAST modes. DM_FAST works fine for me on my completely new installed Ubuntu 20.04 with OpenCV 3.4.13 and ArUco 3.1.12. However i also noticed DM_VIDEO_FAST not functioning correctly see picture attached. I tried it with and without a camera.yml and in the YT-Videos you can see Rafael Muñoz Salinas using it both ways and it functions correctly.

Yes, it is. I had calibrated the camera with aruco_calibration.exe several times and generated the .yml file. I got an error around 2 . However, to answer you I decided to repeat the whole process, and I got in calibrate an error of 0.6. And, with that new file, it works perfectly! Sorry for the inconvenience, and thanks for responding! :-) You can close the 'issue'. JC PS: I have suspicions about what could have happened...

Dictionary is a set of markers. Each library developer has proposed a set of valid markers they detect. I call this a Dictionary of markers.

Thank you a lot RODRIGO... great article, By the way, I have one question of you. Do you have any information about the ArUco marker calculation. For example I would like to create a marker configuration like a octagoan shape. Now, how Can I select markers such that errors rates like the inter-marker distances becomes less.

Hello, Hello David, I solved the problem,. I removed the assert at the begining of the "impl__aruco_getRTMatrix" in posetracker.cpp. And it worked,. Thanks a lot for your comments.
-
Yes to solve the issue you need to modify the source code and rebuild the library. If the problem still persists, I'm not sure what could be the cause. Do you have a different programming environment ? That may be the cause. Initially, to find the error, I observed that the output of tvecs and rvecs using std::cout was correct, but not once set as floats. Do you observe a similar behaviour ?
