1. A sensor alignment system for establishing and maintaining accurate alignment of optical sensors comprising: multiple image sensors collocated on a common substrate and mounted on an automotive vehicle for gathering object data around the vehicle using optical information; a first micro inertial sensor included with the sensors that measures at least one of rotation rate and acceleration along two or more axes of the sensors for the establishment of a sensor reference frame; a second micro inertial sensor mounted on the vehicle that measures at least one of rotation rate and acceleration along two or more axes of the vehicle for the establishment of a vehicle reference frame; and a processor determining an amount of misalignment of the sensor reference frame with the vehicle reference frame and aligning sensor target data with the vehicle reference frame according to the amount of misalignment.
