railroad's Issues

Test Data？

@mcserep
Hello,great work! Can you provide some test data, thank you very much!

When i use the region growth algorithm to segment powerline，how can i get seed cloud from my ".las" point cloud ?

Scans

Hi, thank you for sharing this great work! I'm interested in getting individual scans rather than the reconstructed point cloud. Is that possible? Could you share this information? Thank you in advance!

OpenCV Error

Hello there, we are trying to use this project to identify railroads but continually run into OpenCV errors whether with LAS or LAZ files. We've tried a couple different files of each format but see the same error. Screenshots of trace provided below, any insights would be helpful. Thank you.

Running on LAZ file:

issue opencv

hello MATÉ, i am working on your railroad detection algo , i got issues by executing the algo, i got this message << terminate called after throwing an instance of 'cv::Exception'
what(): OpenCV(4.5.4) ./modules/core/src/matrix_wrap.cpp:1667: error: (-215:Assertion failed) !fixedSize() in function 'release'>>
i seriously need your help to fix that issue. feel free to write in private.

have a good day
