Dear,
Does this lib support any GPU option?
such as sift feature extraction, feature matching etc.

Thanks and Best Regards,

How to visualize the result

Thank you for sharing this great project.
I build it from source on Ubuntu16.04, it rans well, but at last the result is save as result.act. I did not find any guide on how to visualize it, is there any way to transform it to PLY or OBJ format file?

zeros SIFT computed

Hello ZJU3DV,

I was trying your program on a Nvidia GTX 1070 for the Gangwan sequences. However, it extracted 0 SIFT features. Can you please provide a pointer on how to fix this problem?

Thank you!

Issues about running the demo on Ubuntu 16.04

Hello, I have runned the program on the Ubuntu 16.04 and got some output, but I'm comfused about the result and I don't know the meaning of the params in the output file, so is there any explaination about the v0-ftr.txt and v0.act files? and when running the program, the command line output is like the lines followed, and all of the frame feature match is failed, so I want to know if this is normal, and if not, how should I check this program. Very thanks,

SIFT features: 649

Bug find

I changed 'config_plant.txt' file for image paths only. But it can not run out a result.

how to get point cloud and trajectory

hi, although I set view = 1, I still cannot get point cloud and trajectory, could you tell me how to get that please, and BTW, what is in the .act file and how to read that?
