After reading msc_bence.pdf , any monocular cameras is suited for the blort? So I think the color camera in the kinect2 can be used. I set the camera info:=/kinect2/qhd/camera_info and camera image:= /kinect2/qhd/image_mono in the learnsift.launch , but failed. Meanwhile I do the same work in the tracking_histogram_with_kinect.launch ,failed either.

How can I slove this problem?

I have installed BLORT. When I run the program , there is no 3D image in the windows,I try to press "r",but it doesn't work either! I have installed OpenGL,CUDA and OpenCV.

Hello,

I am looking at using BLORT without a gpu. Is it possible to compile BLORT with SIFTCPU or simply without GLSL or CUDA?
I am asking because I would like to use BLORT with a PR2 that does not have a GPU.

Thanks

A .ply file which is listed in the tracking.ini but not found is not reported anyhow, but the tracker fails with segfault when looking up the entry in the ModelEntryList.

due to typo or non-existent file

Otherwise this will not be usable on one of our robots.
