Crashing on import #12

Open marcus-S90 opened 3 years ago

marcus-S90 commented 3 years ago

I am trying to import a file as either las or pcd and the program crashes with no message. I think it may be too large. Is there a work around for files ~5GB?

Hi, LAS file with size over 3 GB can have importing issues, I use workaround to tile the file using i.e. lastools(lastile) and process each tile separately and as final merge only segmented trees into one single project. This contains some manual work to join trees on the border.

I've tried tiling it but the program still crashes. Could this be related to the transformation matrix I'm choosing for the project?

marcus-S90 commented 3 years ago

I was able to get it to accept the tiles but its showing up almost as slices. I've attached the screen capture here. Thanks! 3DForest_Screencap

Your transformation Matrix Is wrong. Your can try negativně values to get it right. Od write coordinates od tvé Furst point in your cloud And se will fond thé right values.

Great yes the coordinates of the first point worked. Thank you!

Hi @janekT I'm using v0.50 and it crashes when I import .las even though its only 4MB in size. it works when I import the sample data base_cloud.pcd

janekT commented 3 years ago

@davodogster thats wierd. Maybe your las file is verion 1.4, that is not supported by liblas that is used for reading las files. can check it?

Sorry I am just ok with computer do you do the lastool (lastile) in R?

Thanks

Hi I used lastile as standalone app from lastools. https://rapidlasso.com/lastools/
