Sensors coupled to a vehicle are calibrated using a calibration environment that includes sensor targets, and optionally includes a motorized turntable that rotates the vehicle to different orientations, with the sensors capturing data at each orientation. The vehicle's computer identifies representations of the sensor targets within the data captured by the sensors, determines whether characteristics such as lighting or positioning of the representations of the sensor targets are optimal for calibration, sends signals to lighting systems or motorized target movement systems if necessary to adjust those characteristics, and calibrates the sensor based on the representations of the sensor targets.
