Abstract

The invention belongs to the field of unmanned aerial vehicle aerial survey, and discloses an unmanned aerial vehicle aerial survey control point arrangement and identification method and system. Themethod comprises the following steps: S1, carrying out the planning of an aerial survey route of an unmanned aerial vehicle on a three-dimensional map; S2, obtaining a ground control point arrangementmap according to the aerial survey route of the unmanned aerial vehicle and a ground control point rule, wherein coordinate information of each ground control point is loaded in the ground control point arrangement map; S3, arranging ground control points according to the ground control point arrangement map; S4, collecting an image internally loaded with the ground control points according to the coordinate information of the ground control points through a three-dimensional attitude sensor and a GPS positioning module which are internally loaded in the unmanned aerial vehicle; and S5, identifying the image through a Dssd_Inception_V3 model. According to the invention, reasonable arrangement of control points and automatic acquisition and identification of images of the control points can be realized, so that a guarantee is provided for smooth aerial survey of the unmanned aerial vehicle.

Description

technical field [0001] The invention belongs to the field of drone aerial survey, and relates to a method and system for arranging and identifying control points of drone aerial survey. Background technique [0002] UAV aerial survey is a powerful supplement to traditional aerial photogrammetry. It has the characteristics of flexible maneuverability, high efficiency and speed, precision and accuracy, low operating cost, wide application range, and short production cycle. It has obvious advantages in acquisition and is widely used in land and resources monitoring and other fields. However, with the continuous deepening of related research and application fields, higher requirements are put forward for the accuracy of UAV aerial survey data, especially in the field of aerial survey. A certain number of control points are arranged in the drone flight area, and the control points are identified to calibrate the drone aerial survey data and improve the accuracy of the drone photo...
