Point Cloud LiDAR Modules from China
1 resources tagged with "Point Cloud"
Point cloud output is the deliverable when sourcing LiDAR modules from Chinese makers like Hesai, Livox, and RoboSense — spinning, solid-state, or MEMS units that stream 3D distance data into ROS or autonomy stacks. The 905nm vs 1550nm wavelength choice trades cost against range and eye-safety margin, and frame rate plus angular resolution determine point density. Note that some higher-end automotive LiDAR falls under export-control scrutiny, so confirm shipping eligibility early.
When you source a LiDAR module, match point density, range, and field of view to your perception task, and verify the SDK exposes a ROS driver if you need it. The pitfall is buying on max-range specs that assume ideal reflectivity targets.

FAQ
What's the difference between 905nm and 1550nm LiDAR?
905nm uses cheaper silicon detectors but is eye-safety limited on power; 1550nm allows higher power for longer range at higher cost. For short-to-mid range robotics, 905nm is the common choice.
Are there export restrictions on Chinese LiDAR?
Some automotive-grade LiDAR is subject to export control depending on specifications and destination. Confirm the supplier can legally ship your model to your country before committing.
