Abstract

The invention provides a pod calibration method, device, electronic equipment and storage medium of a drone, relates to the technical field of drone control, and is invented to solve the problem of poor calibration effect of the pod; the method includes: obtaining the pod lens The actual picture taken; obtaining the virtual picture obtained based on the first frame angle of the pod; superimposing the virtual picture and the actual picture to obtain a processing result; according to the processing result, performing Calibration; the frame angle is used to represent the angle of the pod relative to the nose of the drone. The solution of the invention makes the calibration result of the pod accurate and the calibration effect better.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicle control, in particular to a pod calibration method, device, electronic equipment and storage medium of an unmanned aerial vehicle. Background technique [0002] In the application of the UAV, it is necessary to mount the camera equipment through the pod to take pictures. Existing pods mainly include two-axis and three-axis pods, and the three-axis pods have higher precision, so they are more widely mounted on UAVs. The frame angle of the pod (that is, the angle of the pod lens relative to the nose of the UAV) is obtained by an angle sensor. The sensors used include linear Hall, photoelectric encoder, magnetic encoder, etc. Structural changes or environmental changes may cause offsets and errors. For example, sensors such as Hall and magnetic encoders are deformed and displaced, resulting in changes in the detection distance, or the optical encoder enters dust and other impurities...
