Latest Patents

Jijie Xu holds a patent for a "Calibration system for concurrent calibration of device sensors." This system includes a grid assembly, a platform, and a controller. The grid assembly features at least one planar grid, while the platform is designed to couple with a device under test (DUT) and move it to multiple test positions according to a specific motion sequence. Each position is achieved through rotation about at most two different axes. As the DUT navigates through the motion sequence, at least one camera captures image information related to the grid assembly, and an inertial measurement unit (IMU) collects IMU information. The controller then determines calibration information for both the camera and the IMU based on a parameterized model of the DUT's motion sequence, along with the captured image and IMU data.
