1. A vision system for a vehicle, said vision system comprising:

  • a plurality of imaging sensors disposed at the vehicle and having respective exterior fields of view, each of said imaging sensors capturing image data;

    a control disposed at the vehicle;

    wherein said imaging sensors are connected to said control via respective ones of a plurality of single core coaxial cables;

    wherein each said single core coaxial cable commonly carries (i) image data from the respective imaging sensor, (ii) power to the respective imaging sensor and (iii) communication data;

    wherein each of said imaging sensors is operable to transmit calibration data to said control;

    wherein each of said imaging sensors transmits calibration data when the respective imaging sensor is triggered to transmit calibration data;

    wherein said vision system, responsive to receipt of calibration data by said control, is operable to identify the respective one of said imaging sensors transmitting the received calibration data; and

    wherein each of said imaging sensors transmits calibration data responsive to detection of a particular pattern in the field of view of the respective imaging sensor.
