I am new to this field, I have collected some point cloud data using lidar sensor and camera and now I have .pcd files for the point cloud and .png files for the images. I wanted to make this data like the KITTI dataset structure for 3d object detection to use it in a model that uses kitti dataset as training data for 3D object detection. Therefore I want to change my .pcd files to .bin files like in kitti and also I need to have .txt files for labels, so i need to annotate my data in such a way that will give me the same label files like in kitti dataset. Can somebody help me ?. I searched a lot and all the labelling tools don’t output the same attributes that are in the .txt files of KITTI. This is the link for the KITTI 3D dataset. http://www.cvlibs.net/datasets/kitti/eval_object.php?obj_benchmark=3d

There is a lot of different questions in your post, so I'm going to answer those I can. Here is a snippet of code how you can read pcd file:
import open3d as o3d
pcd = o3d.io.read_point_cloud("../../path_to_your_file.pcd")
#print(pcd)
and then you can format it as you want, including writing to binary. This could be a helpful library, check this out
