  • Patent number: 10992928
    Abstract: A calibration system includes a grid assembly, a platform, and a controller. The grid assembly includes at least one planar grid. The platform couples to a device under test (DUT) and move the DUT to a plurality of test positions in accordance with a motion sequence. Each test position is reached by a rotation about at most two different axes, and as the DUT moves through the motion sequence, at least one camera on the DUT captures image information describing portions of the grid assembly and an inertial measurement unit (IMU) on the DUT captures IMU information. The controller determines calibration information for the at least one camera on the DUT and for the IMU based in part on a parameterized model of the motion sequence of the DUT, the captured image information, and the captured IMU information.
