Abstract: A method for calibrating a device having a first sensor and a second sensor. The method includes capturing sensor data using the first sensor and the second sensor. The device maintains a calibration profile including a translation parameter and a rotation parameter to model a spatial relationship between the first sensor and the second sensor. The method also includes determining a calibration level associated with the calibration profile at a first time. The method further includes determining, based on the calibration level, to perform a calibration process. The method further includes performing the calibration process at the first time by generating one or both of a calibrated translation parameter and a calibrated rotation parameter and replacing one or both of the translation parameter and the rotation parameter with one or both of the calibrated translation parameter and the calibrated rotation parameter.

Abstract: Disclosed here in are systems and methods for mapping environment information. In some embodiments, the systems and methods are configured for mapping information in a mixed reality environment. In some embodiments, the system is configured to perform a method including scanning an environment including capturing, with a sensor, a plurality of points of the environment; tracking a plane of the environment; updating observations associated with the environment by inserting a keyframe into the observations; determining whether the plane is coplanar with a second plane of the environment; in accordance with a determination that the plane is coplanar with the second plane, performing planar bundle adjustment on the observations associated with the environment; and in accordance with a determination that the plane is not coplanar with the second plane, performing planar bundle adjustment on a portion of the observations associated with the environment.

Abstract: Examples of the disclosure describe systems and methods for presenting virtual content on a wearable head device. In some embodiments, a state of a wearable head device is determined by minimizing a total error based on a reduced weight associated with a reprojection error. A view reflecting the determined state of the wearable head device is presented via a display of the wearable head device. In some embodiments, a wearable head device calculates a first preintegration term and second preintegration term based on the image data received via a sensor of the wearable head device and the inertial data received via a first IMU and a second IMU of the wearable head device. The wearable head device estimates a position of the device based on the first and second preintegration terms, and the wearable head device presents the virtual content based on the position of the device.
