Sensor Calibration Tool
For Autonomous Vehicles
The integration of sensors has become the standard for most autonomous vehicles, but spending hours calibrating them consumes valuable testing and development time. The Dataspeed Sensor Calibration Tool is meant to aid users in setting up the extrinsics calibration of a suite of sensors on a vehicle. This convenient tool reduces the hassle of sensor setup and allows the user to spend more time on essential autonomous or data collection research.
Lidar Ground Plane Alignment
This calibration mode inputs the point cloud from a 3D lidar sensor, detects the ground plane in the cloud, and then adjusts the roll angle, pitch angle, and z offset of the transform from vehicle frame to lidar frame such that the ground plane is level and positioned at z = 0 in vehicle frame.

Multi-Lidar Alignment
This calibration mode inputs point clouds from two 3D lidar sensors and computes the translation and orientation between the sensors’ coordinate frames. It does this by comparing distinguishing features in the overlapping point clouds.
Lidar-Camera Overlay
This tool overlays a lidar point cloud on a camera image in real time according to the current extrinsic transform between the two sensors. This can be used to adjust and verify the transform.

Camera-Camera Overlay
This tool constructs a composite image that visualizes the overlap between two camera images according to the current extrinsic transform between the cameras. This can be used to adjust and verify the transform.
