uos / lvr2 Goto Github PK

Hi @spuetz, any plans for an lvr2_ros package and/or a refresh for organized_fast_mesh someday?

Is there any windows x64 compatibility planned?

Hi,

I am trying to reconstruct a mesh from a point cloud that was exported using google cartographers assets writer. The data used is from "Deutsche Museum" which was scanned by the google cartographer team.

I played around with different parameters such as the smallRegion, fillHoles, ransac, and the different algorithms MC, PMC, SF and MT.
No matter what parameters I choose, I always have alot of holes in the mesh, which look like the triangles are not connected correctly.

In this dataset the robot has a fixed position. I understand that since I don't provide the position of the robot (which is 0, 0, 0) the orientation of the normals can be inconsistent. Is this a problem for LVR when connecting the triangles?

Could it be, that the quality of the point cloud is just not good enough? Its a single room, which consists of 50M points.

Any advice is appreciated.

E: Für Paket »openmpi-dev« existiert kein Installationskandidat.

There is libopenmpi-dev (https://packages.ubuntu.com/bionic/libopenmpi-dev).

E: Paket libvtk-qt-dev kann nicht gefunden werden.

There is libvtk7-qt-dev.

Please clarify/adopt the README. Additionally, surely cmake-ncurse-gui is no mandatory dependency, or?

Problem: lvr2_reconstruct crashes on some meshes when both --optimizePlanes and --fillHoles are used

LVR version: 20.11.3 (9bb03a3)

System info: Ubuntu 20.04

How to reproduce:

I've attached some test data here: minimal_examle.ply

• lvr2_reconstruct -o minimal_examle.ply: works
• lvr2_reconstruct -f 15 minimal_examle.ply: works
• lvr2_reconstruct -o -f 1 minimal_examle.ply: works
• lvr2_reconstruct -o -f 15 minimal_examle.ply: crashes:

Hi,
im trying to compile LVR2 on Mac OS (10.15 Catalina).

It seems that OpenCL can not be found, but im unsure why.

I am getting the following error, when trying to use "cmake .." from build folder.

Any ideas, what I can try to debug this issue?

Hi,

I want to use a previously created .pcd cloud point as map for the mesh_navigation package. I understand that it needs to be transformed to h5 format.

I've tried the tools provided by this package after converting pcd to ascii point clouds, but I only get core dumps. I haven't been able to find any documentation, as I've been unable to make the documentation as instructed (make doc).

Can you kindly provide some example or instructions for building a h5 map from other data?

Thank you.

We're building packages in the robostack project, including this one to make it easy to install ROS with conda: https://github.com/robostack/ros-noetic

Unfortunately gdal seems to be missing from the package.xml file?

Currently the lv2r package is not installable in Noetic without conflicting with libpcl-dev.
The rosdep key has been fixed in ros/rosdistro#27768, but the lvr2 deb has not been updated since making it still uninstallable on noetic.

Is it possible to rebloom/release v20.11.2 in Noetic to fix the dependency list ?

Thanks!

What algorithms are used namely to generate the different mesh map as implemented in this repo?

I am getting the following error OpenCL error at /tmp/binarydeb/ros-melodic-lvr2-20.11.3/src/liblvr2/reconstruction/opencl/ClSurface.cpp:466 code=-1001(Unspecified Error) "clGetPlatformIDs(0, NULL, &num_platforms)" Wrong platform id terminate called after throwing an instance of 'boost::exception_detail::clone_impl<boost::exception_detail::error_info_injector<boost::lock_error> >' pure virtual method called terminate called recursively . I am not sure where the problem is since I also can't reproduce it on another similar embedded platform.
