Methods and systems for calibrating sensors of a computing device

摘要

Methods and systems for calibrating sensors on a computing device are described herein. In an example implementation, a computing device may perform a method to calibrate one or more sensors, which may include receiving an indication that a sensor has been calibrated. The computing device may further receive independent observations of a motion of a device from the calibrated sensor and a potentially non-calibrated sensor. The device may determine as independent estimation of motion based on the movement of the device corresponding to the outputs of the respective sensors. Based on whether or not the estimation of motion as provided by the potentially non-calibrated sensor is within a threshold variance of the estimation of motion as provided by the calibrated sensor, the computing device may provide instructions to adjust parameters of the non-calibrated sensor.

1. A method performed by a device having a plurality of sensors, the method comprising:
receiving information indicating that a first sensor of the plurality of sensors has been calibrated; receiving from the first sensor and a second sensor of the plurality of sensors outputs indicative of independent observations of a motion of the device; determining a first estimation of the motion of the device based on the output of the first sensor and a second estimation of the motion of the device based on the output of the second sensor; determining whether the second estimation of motion of the device is within a threshold variance of the first estimation of motion of the device; and based on whether the second estimation of motion of the device is within the threshold variance of the first estimation of motion of the device, providing instructions to adjust one or more parameters of the second sensor.
