A portable device includes a sensor, a video capture module, a processor, and a computer-readable memory that stores instructions. When executed on the processor, the instructions operate to cause the sensor to generate raw sensor data indicative of a physical quantity, cause the video capture module to capture video imagery of a reference object concurrently with the sensor generating raw sensor data when the portable device is moving relative to the reference object, and cause the processor to calculate correction parameters for the sensor based on the captured video imagery of the reference object and the raw sensor data. |
