This is in regard with the spherical projection from 3d lidar points to a 2d plane.I actually have a pcap lidar file and the code expects a pcd file as input,I tried converting the pcap to pcd using matlab but the resultant intensity image is bad.Do you have any source to suggest which can help me to convert the pcap to pcd format as expected by the code.
I am using a velodyne VLP- 32C lidar.
Any suggestion is appreciated.
Thank you

Hi, Thank you for the great work.

I want to use spherical projection on my VLP-16 lidar and use ROS that subscribe /velodyne_points topic instead of loading bin file. But I'm not sure about how to use ros topic as input.

May I have your suggestions?
Any help is much appreciated!

Hello, I am trying to follow the build instructions. When I get to typing cmake .. on the command line, I get the following error:

CMake Error at /opt/homebrew/lib/cmake/vtk-9.2/VTK-targets.cmake:973 (set_target_properties):
  The link interface of target "VTK::jsoncpp" contains:

    JsonCpp::JsonCpp

  but the target was not found.  Possible reasons include:

    * There is a typo in the target name.
    * A find_package call is missing for an IMPORTED target.
    * An ALIAS target is missing.

Call Stack (most recent call first):
  /opt/homebrew/lib/cmake/vtk-9.2/vtk-config.cmake:138 (include)
  /opt/homebrew/share/pcl-1.13/PCLConfig.cmake:271 (find_package)

  /opt/homebrew/share/pcl-1.13/PCLConfig.cmake:554 (find_external_library)
  CMakeLists.txt:6 (find_package)

Any guidance on whether this is related to my MacOS or whether this repo is still functioning?

Hey @anirudhtopiwala ,great work!
I am trying to convert my vlp-16 point cloud to 2d image by using this repo.I changed the following parameters in the code
For VLP-16
Fov_Up = 15 degrees
Fov_Down = -15 degrees
Num of Lasers = 16
Length of the image =1024
But I got a very bad result.Is there any other thing I am missing out?

Thank you
