### My Question

I am having trouble with my point cloud files in PCD format when using Open3D. After reading the files into Open3D using the read_point_cloud function, the point cloud appears to be segmented into horizontal aranged that are approximately 25cm apart along the y-axis. Within each aranged line, the points are spaced approximately 3cm apart along the y-axis. However, the total number of points in the point cloud remains unchanged.

I have tried visualizing the same files using LIDAR 360 and CloudCompare, and they appear normal. The problem only seems to occur after reading the files into Open3D.
