Abstract: According to one aspect, a method includes positioning a lidar on a platform, measuring at least a first data point using the lidar, measuring at last a second data point using the lidar, processing the at least first data point and the at least second data point to identify a first estimated location of the vertex, and determining whether the first estimated location of the vertex meets the specification, wherein when it is determined that the first estimated location of the vertex meets at least one specification associated with the lidar, the lidar is verified. The platform rotates about a first axis, wherein when the platform rotates about the first axis, the lidar rotates about the first axis. The data points measured with respect to a target, the target having at least a first edge, a second edge, and a vertex at which the first edge meets the second edge.

Abstract: According to one aspect, a method includes obtaining an assembly, the assembly including at least a first assembly sensor and a second assembly sensor of a plurality of assembly sensors, and calibrating the first assembly sensor and the second assembly sensor. The method also includes calibrating the first assembly sensor and the second assembly sensor together, wherein calibrating the first assembly sensor and second assembly sensor together includes placing the assembly in at least a first pose relative to a plurality of calibration targets. The assembly is coupled on a vehicle, and the plurality of assembly sensors are calibrated after coupling the assembly on the vehicle. Calibrating the plurality of assembly sensors after installing the assembly on the vehicle includes causing the vehicle to move relative to the plurality of calibration targets and using the plurality of assembly sensors to make measurements using the plurality of calibration targets.
