Selection method of take-off and landing points in urban areas for fixed-wing unmanned aerial vehicles

Abstract

The selection system used in the present invention includes a database module, and also includes a sequentially connected measurement area range determination module, a field survey module, a data processing module, and a correction reminder module; The steps of the height difference L of the take-off and landing point of the UAV, the pre-selection step of the take-off and landing area, the optimization step of the take-off and landing area, the steps of determining the take-off and landing point and implementing the correction step; Quickly realize the optimization of take-off and landing points in the urban environment, greatly improving the aerial survey accuracy of fixed-wing UAVs, taking into account the premise that when the height difference of take-off and landing points increases by 1m, the UAV will fly forward 10-20m more when landing Conditions, set the correction steps to prevent the drone from deviating from the scheduled landing point, greatly reduce the take-off and landing error, ensure the safe take-off and landing of the drone, greatly reduce the aerial survey cost of the drone, and reduce the workload , which is more suitable for promotion.

Description

Technical field [0001] The invention belongs to the technical field of drone aerial surveys, and relates to a fixed-wing drone take-off and landing technology, and more specifically, to a method for selecting a fixed-wing drone urban take-off and landing point. Background technique [0002] As we all know, fixed-wing UAVs have a wide range of aerial surveys, fast speed, and high efficiency, and are increasingly used in terrain surveying and mapping. However, due to their fixed-wing properties, this type of UAV has stricter requirements for landing locations. Harsh. The Tianbao UX5 drone needs a flat ground that is at least 50 meters long and 30 meters wide. It is best to choose a field that is open, relatively soft and free of hard objects such as rocks, and try to avoid hard landing on cement roads. When performing surveying and mapping tasks, it is inevitable to encounter more complicated terrain conditions and unable to find a large area of ​​open space, which is extremely de...

AI Technical Summary

Problems solved by technology

The selection of take-off and landing points takes a lot of time, resulting in a waste of manpower and material resources

In addition, the existing methods for selecting take-off and landing points in urban areas for drones are all aimed at the ideal urban environment, and there is no special detailed classification of the urban environment, and there are no measures to deal with the impact of sudden weather conditions; the most important Yes, the existing methods for selecting take-off and landing points in urban areas for UAVs do not have special aerial survey correction measures, and UAVs tend to deviate from the scheduled landing points, and cannot perform safe take-off and landing in urban areas very well and accurately.
