Embodiment 1

[0033] Embodiment 1 is basically as attached figure 1 Shown: a UAV aerial photogrammetry teaching system, including a sand table model, a UAV and a ground station; the sand table model is used to simulate the operating environment; the UAV is used to photograph and measure the sand table model, The ground station is used to set and generate the operating parameters of the drone; in this embodiment, the drone is a small shooting drone equipped with a single-lens camera, which is suitable for indoor simulation teaching.

[0034] The ground station includes a ground controller and a display; the display is used to acquire and display the operating parameters of the unmanned aerial vehicle; the control program of the unmanned aerial vehicle is stored in the controller; the control program of the unmanned aerial vehicle is used to set and Generate operation parameters of the UAV; the operation parameters include operation area, heading overlap, side overlap, flight speed, flight st...

Embodiment 2

[0047] The difference between this embodiment and Embodiment 1 is: the UAV control program also includes an acquisition module, an evaluation module and an analysis module;

[0048] The controller is also used to record the number of times of obstacle avoidance of the drone;

[0049] The acquisition module is used to acquire the operating parameters of the drone, the number of times of obstacle avoidance of the drone, and the shooting results of the drone;

[0050] The ground controller is also used to control the display to display the shooting results of the drone;

[0051] The mutual evaluation module is used to rate the operation process of the drone, and the levels include A, B, C, and D, with A being the best and decreasing in turn.

[0052] The evaluation module is used to evaluate the operation process of the UAV; the evaluation standard is: score the operation process of the UAV according to the clarity of the shooting results of the UAV; Fraction;

[0053] The ana...

Abstract

The invention belongs to the technical field of aerial photogrammetry, and discloses an unmanned aerial vehicle aerial photogrammetry teaching system. The system comprises a sand table model, an unmanned aerial vehicle and a ground station. The sand table model is used for simulating a working environment; the edge of the sand table model is provided with N electronic tags, and N is greater than or equal to 3; a reflecting plate is arranged above the sand table model; and the unmanned aerial vehicle is a shooting unmanned aerial vehicle, the unmanned aerial vehicle is used for carrying out shooting measurement operation on the sand table model, and the ground station is used for setting and generating operation parameters of the unmanned aerial vehicle. The position information of the unmanned aerial vehicle is determined by detecting the distance between the unmanned aerial vehicle and the electronic tag and the distance between the unmanned aerial vehicle and the reflecting plate. The problems that in the prior art, due to the fact that a traditional unmanned aerial vehicle navigation positioning mode cannot accurately position the unmanned aerial vehicle in a small-area room, an existing indoor teaching aerial survey mode is greatly different from actual unmanned aerial vehicle aerial survey operation, comprehensive teaching cannot be performed on unmanned aerial vehicle aerial photogrammetry, and the teaching effect is poor are solved.

Description

technical field [0001] The invention belongs to the technical field of aerial photogrammetry, and in particular relates to a teaching system for aerial photogrammetry of an unmanned aerial vehicle. Background technique [0002] Aerial photogrammetry refers to the operation of continuously taking pictures of the ground with aerial photography instruments on aircraft or other aircraft, and drawing topographic maps by combining the steps of ground control point measurement, surveying and mapping, and three-dimensional surveying and mapping. As a new aircraft, UAV is used in aerial photogrammetry. Compared with the aerial photogrammetry of traditional aircraft, it has the characteristics of flexible, efficient, fast, precise and accurate, low operating cost, wide application range, and short production cycle. , has obvious advantages in the rapid acquisition of high-resolution images in small areas and difficult-to-flight areas, so the demand for UAV aerial photogrammetry operat...
