Embodiment Construction

[0035] see figure 1 , which is a flowchart of a method for constructing a UAV inspection route according to an embodiment of the present invention.

[0036] The steps of the method for extracting and constructing a high-precision UAV route in this embodiment are as follows:

[0037] S1 obtains the video image loaded with the subtitle file taken by the drone;

[0038] S2 extracts the time and position information of the route point in the subtitle file in the video image;

[0039] S3 converts the geographic coordinates in the location information of the route points into Cartesian coordinates;

[0040] S4 calculates the corners formed by every three consecutive route points according to the time information of the route points, and deletes the corner points whose corners are lower than 90 degrees;

[0041] S5 connects the remaining waypoints sequentially, interpolates with a Bezier curve to optimize the trajectory of the waypoints into a curve;

[0042] S6 establishes key f...

Abstract

The invention discloses a method for constructing an inspection route of an unmanned aerial vehicle. The method comprises the following steps: extracting route point position and time information froman unmanned aerial vehicle subtitle file by using a data extraction technology, converting route point position coordinates by using a projection conversion algorithm, removing wrong route point coordinates, carrying out smooth processing on connecting lines of remaining route points, and simulating by using a three-dimensional rendering technology to realize monitoring and management of an unmanned aerial vehicle inspection process.

Description

technical field [0001] The invention relates to technical fields such as three-dimensional graphics rendering, three-dimensional simulation, data extraction, projection conversion, etc., and in particular refers to a method for constructing a UAV inspection route. Background technique [0002] UAV inspection video is the video image data collected during UAV inspection. For most UAVs (such as DJI UAVs), during the collection process, the location information at the time of collection is often recorded and embedded into the video data in the form of subtitles, so the subtitles can be The location information in the drone is extracted, and through the three-dimensional graphics rendering technology, the flight simulation and replay of the drone are realized, so that users can see the corresponding location and flight track of the drone on the map while browsing the video. This facilitates effective monitoring and management of the UAV inspection process. [0003] However, du...
