Unable to mark vanishing lines #27

Open Ashish2Parimi opened 3 years ago

Ashish2Parimi commented 3 years ago

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. Screenshot from 2021-07-02 10-47-23

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.

Ashish2Parimi commented 3 years ago

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?

zhengthomastang commented 2 years ago

We were using OpenCV 3.6 at that time. Maybe "CV_AA" is no longer available in the latest version?

Ashish2Parimi commented 2 years ago

Yes it is not available along with few others. So I had to replace them. I will try using 3.6

Ashish2Parimi commented 2 years ago

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 ?

zhengthomastang commented 2 years ago

@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

Ashish2Parimi commented 2 years ago

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. Screenshot from 2021-08-09 16-41-12

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. pic

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.
