Abstract

The invention discloses a data calibration method and device. The method comprises the following steps: establishing a closed loop control system of a filter, performing iterative filtering processing for n times on the to-be-calibrated data by using a self-adaptive filter, wherein the filter parameter used in each iterative filtering processing is the filter parameter obtained after updating the difference between the output data obtained after former iterative filtering processing and the preset reference output data, thereby reducing the error of the output data and improving the data precision.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a data calibration method and device. Background technique [0002] At present, many smart devices have modules with high precision data requirements, such as batteries, sensors and other modules. The sensor of the man-machine will guide the direction of flight, and the sensor of the virtual reality device will affect the user's immersive experience brought by the rotation of the 3D scene. [0003] In order to ensure the accurate operation of smart devices, it is necessary to perform accurate data calibration on the modules that provide data output in smart devices to ensure that they can provide high-precision data. In the prior art, the calibration scheme provided by the original manufacturer of the above-mentioned modules is only It is limited to the data calibration of the module when it leaves the factory. In practical applications, the data error generated by the modul...
