发明名称 Methods and Systems for Cross-Validating Sensor Data Acquired Using Sensors of a Mobile Device
摘要 Methods and systems for cross-validating sensor data are described. An example method involves receiving image data and first timing information associated with the image data, and receiving sensor data and second timing information associated with the sensor data. The method further involves determining a first estimation of motion of the mobile device based on the image data and the first timing information, and determining a second estimation of the motion of the mobile device based on the sensor data and the second timing information. Additionally, the method involves determining whether the first estimation is within a threshold variance of the second estimation. The method then involves providing an output indicative of a validity of the first timing information and the second timing information based on whether the first estimation is within the threshold variance of the second estimation.

主权项 1. A method performed by a mobile device having a plurality of sensors, the method comprising: receiving image data and first timing information associated with the image data, wherein the image data includes images representative of a motion of the mobile device and is determined using a first sensor of the plurality of sensors; receiving sensor data and second timing information associated with the sensor data, wherein the sensor data corresponds to the motion of the mobile device and is determined using a second sensor of the plurality of sensors; determining a first estimation of the motion of the mobile device based on the image data and the first timing information; determining a second estimation of the motion of the mobile device based on the sensor data and the second timing information; determining whether the first estimation of the motion of the mobile device is within a threshold variance of the second estimation of the motion of the mobile device; and based on whether the first estimation of the motion of the mobile device is within the threshold variance of the second estimation of the motion of the mobile device, providing an output indicative of a validity of the first timing information and the second timing information.
