Abstract
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.
