Unable to mark vanishing lines
I was trying to set my own vanishing lines for my video, but when I move my move over the image the lines are plotted with even clicking. Unfortunately I cannot use the new method as I am unaware of the location of the video. Hence please let me know how to fix this.
The lines will only be plotted when you click within the UI. Please try to use another monitor if your current one cannot display the full interface.
Thank you! I have tried different monitors but still have the same issue where the lines are plotted without clicking. When I try to move mouse in the UI the lines are automatically plotted.
I am using Opencv4. So I had to update the code by replacing elements like "CV_AA" to match the current commands. Is that causing the problem? Which version of OpenCV should be used for the code to run?
We were using OpenCV 3.6 at that time. Maybe "CV_AA" is no longer available in the latest version?
Yes it is not available along with few others. So I had to replace them. I will try using 3.6
Unfortunately I did not find Opencv3.6. The official documentation only mentions up to 3.4 and the 4 and later versions. I have tried 3.4 but it says libopencv not found. I was unable to find a way to manually install it. is there any alternate version or resource ?
@Ashish2Parimi You can try any version as long as "CV_AA" is available. It seems there is an alternative in the latest OpenCV version that might help: https://github.com/xiaohulugo/VanishingPointDetection/issues/3
I was able to make all the changes and run the code now. Although the final part Speed estimation runs for around 30 seconds and throws the following error. I do have 48772 images.
When I had a search, they mention its related to RAM. Please let me know if its a hardware limitation or is there any way to make it run. If possible recommend specifications.
I am using Intel 9750H GTX 1660Ti 6GB 16GB Ram
Thanks Ashish
I have also tried running it on a different system. and got the following error.
Specs: Xeon E5-2630 v2 Quarto k4000 64GB ram
Hello,
I was able to solve the problem. It was related to the index of trk2d.txt which starts from 1 but the code considers it from zero. Despite of altering lines 303,304. The if loop in 315 fails to assign objects to vvoTrkNd vector at index zero. I had to add few lines to make it work. But not sure if its the right thing to do.
