Aircraft-based mapping method, device and system

Abstract

The invention discloses an aircraft-based mapping method, device and system. The aircraft-based mapping method comprises the steps of acquiring an image of an aircraft during flight, and displaying areference mark and an image for alignment in an image display interface; receiving trigger operation input by a user; recording a mark point in the image according to the trigger operation; and acquiring position information of an actual mapping point corresponding to the mark point according to a mapping relation between the image and the true position. According to the aircraft-based mapping method disclosed by the embodiment of the invention, the problem of low mapping efficiency of a mapping person can be solved compared with artificial dot mapping; and compared with traditional unmanned aerial vehicle mapping, the mapping control process is simplified, the mapping efficiency is improved, and the corresponding high-accuracy position information can be mapped within a short time.

Description

technical field [0001] The invention relates to the technical field of UAV flight control, in particular to an aircraft-based surveying and mapping method, device and system. Background technique [0002] There are two main methods for map surveying and mapping, one is surveying and mapping by unmanned aerial vehicle. Generally, UAV surveying and mapping needs to plan the route in advance and then use the UAV to survey and map according to the route. In the later stage, the photos need to be stitched by software. This kind of surveying and mapping method is too complicated and time-consuming. For some routes that urgently need high-precision Not practical for the occasion. [0003] The other is to perform manual surveying and mapping. Manual surveying and mapping generally means that workers hold hand-held surveying and mapping equipment in their hands to manually walk on the sites that need to be surveyed and mapped (such as manual surveying and mapping of farmland boundar...
