In one embodiment, a method includes detecting multiple reference markers on a vehicle and multiple reference markers on a sensor array attached to the vehicle. The method includes determining a pose of the vehicle and a pose of the sensor array based on the detected reference markers on the vehicle and sensor array and a model of the vehicle and sensor array that includes expected locations of the detected reference markers on the vehicle and sensor array. The method includes computing an observed relative orientation between the sensor array and the vehicle based on a comparison of the determined pose of the sensor array and vehicle. The method includes determining a calibration factor for a sensor of the sensor array based on a comparison of the observed relative orientation between the sensor array and the vehicle to an expected relative orientation between the sensor array and the vehicle.
