Acces point cloud

  • Hello everyone!

    I have a simple question, how can you acces the point cloud of the camera? Or is points_3d the point cloud?

    I have been experimenting with both the Tau Lidar camera and an external library called open3d, which is used to visualize point clouds. I tried to use points_3d to visualize the point cloud by converting it into a .ply file, but noticed the point cloud wasn't as accurate as i had hoped it to be.

    Here are some examples as to what I mean:

    This is something similiar to what I expect/desire, an accurate point cloud based of what the camera sees:

    What is the correct way of getting the point cloud from the camera? Or is the points_3d list indeed the point cloud, but is it not getting an accurate result due to, for example, an incorrect integration time?

    Thanks in advance for any help! I would love to hear what I am doing wrong or how I could get my wanted result. I would even be grateful for an explenation of how to actually get the point cloud. Thanks!
