SYSTEM AND METHOD FOR SIMULTANEOUSLY MULTIPLE SENSOR CALIBRATION AND TRANSFORMATION MATRIX COMPUTATION

The present teaching relates to apparatus, method, medium, and implementations for simultaneously calibrating multiple sensors of different types. Multiple sensors of different types are first activated to initiate simultaneous calibration thereof based on a 3D construct including a plurality of fiducial marks. Sensors of different types including visual and depth based sensors operate in their respective coordinate systems. Each of the sensors is calibrated by acquiring sensor information of the 3D construct, detecting a feature point on each of the plurality of fiducial markers based on the sensor information, estimating a set of 3D coordinates, with respect to its coordinate system, corresponding to the detected feature points, based on which calibration parameters are generated. Sets of 3D coordinates derived in different coordinate systems are then used to compute at least one transformation matrix for corresponding at least one pair of the plurality of sensors.
