Abstract

The invention discloses a data processing method and device as well as a compass calibration method and device and relates to the technical field of computers. Original data acquired by a compass is subjected to coordinate transformation to generate transformed data; the transformed data and the original data are used together as calibration data of the compass; the original data is used for expanding data for calibration; the problem that the data for calibrating the compass is insufficient is solved and subsequent compass calibration work is convenient to carry out.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a data processing method and device, and a compass calibration method and device. Background technique [0002] An electronic magnetic compass is generally installed on the UAV to control its heading to ensure the accuracy of the flight trajectory. The measurement accuracy of the electronic magnetic compass plays a very important role in the flight control of the UAV. [0003] Affected by environmental factors and the electronic magnetic compass itself, the electronic magnetic compass usually has measurement errors. Therefore, the electronic magnetic compass needs to be calibrated. Before the electronic magnetic compass is calibrated, a large amount of data needs to be collected for calibration. However, in the prior art, insufficient data collected for calibration often occurs due to reasons such as irregular operation, which brings inconvenience to the calibration of the ele...
