Method and device for automatically correcting route of unmanned aerial vehicle

Abstract

The invention provides an unmanned aerial vehicle route automatic correction method and device, and the method comprises the steps: obtaining an image obtained by photographing at each aerial photographing point by a camera device according to a preset pan-tilt angle in a flight process based on an obtained planned route; the method comprises the following steps: acquiring positioning information of a target object in each image by using a pre-trained recognition model, correcting an aerial photographing point during image photographing when judging that a cradle head exceeds a limit based on the positioning information, and further correcting a planned route based on the corrected aerial photographing point to obtain an updated route. According to the scheme, the mode of obtaining the recognition model through pre-training is adopted, the image of each aerial photography point in the planned route can be recognized and detected, then the route is automatically corrected, and the problem that the efficiency is low due to manual recognition and adjustment is avoided.

Description

technical field [0001] The present application relates to the technical field of unmanned aerial vehicles, and in particular, to a method and device for automatic correction of UAV routes. Background technique [0002] At present, through data communication between the unmanned software and the gimbal, the gimbal automatically shoots according to the set aerial photography point and the preset pitch angle during the planned navigation mission of the drone. The image data is processed by the next application. However, in the process of route verification, there may be a phenomenon that the PTZ exceeds the limit of the aerial photography point. At present, the usual processing method is to adjust the PTZ angle by point-by-point manual editing during the route verification stage to avoid invalid aerial photography points. In the prior art, there is a lack of a method for automatically calculating and adjusting the angle, so as to effectively avoid the damage to the gimbal caus...

Problems solved by technology

However, during the route verification process, there may be a phenomenon that the aerial photography point pan / tilt exceeds the limit. At present, the usual processing method is to adjust the pan / tilt angle through point-by-point manual editing during the route verification stage to avoid invalid aerial photography points.

In the prior art, there is a lack of a method for automatically calculating and adjusting the angle to effectively avoid damage to the gimbal caused by the overrun of the gimbal rotation angle
