Lidar Calibrations

1min

A LIDAR calibration is represented as a LidarCalibration object and consists of a position expressed with three coordinates and a rotation in the form of a Quaternion. Optionally, the sensor's field of view may be specified by providing an object that has a sweep start angle and sweep stop angle. The field of view may also optionally include the depth to which the field extends.
Key
Value
Parameters
rotation_quaternion
A RotationQuaternion object
w, x, y, z
position
A Position object
x, y, z
field_of_view (optional)
