Problems solved by technology

[0003] At the same time, in view of the existing on-site construction of the power station, in order to facilitate the survey of the current building appearance, find possible safety hazards, or compound the gap between the actual size and the architectural drawings, manual on-site measurement is required
[0004] However, due to the large base of the power station, its roof and side walls are often difficult to provide more accurate data obtained manually, and there are certain safety hazards during the manual survey

Embodiment Construction

[0021] Below in conjunction with the examples, the specific implementation of the present invention will be further described in detail. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0022] The UAV-based power station site survey method is different in that:

[0023] First of all, the image collection of the power station site is carried out through the drone. During this period, in order to obtain more accurate measurement data, the drone performs satellite positioning on the collected images, and binds specific geographic information parameters with image information. Or, in order to realize one-to-one fixed-point survey, drones can also be used to collect images of corresponding points according to satellite positioning. In this way, different survey needs of the power station site can be met.

[0024] Afterwards, through the image processing terminal, the image is filtered and pro...

Abstract

The invention relates to a power station site survey method based on an unmanned aerial vehicle. The method comprises the following steps: collecting an image of a power station site through an unmanned aerial vehicle; filtering the image and processing the image into a 3D model through an image processing terminal; acquiring real scale data based on the 3D model through a data processing terminal; and finally, finding points of difference from the real scale data, and completing data modeling. A site image can be collected directly through an unmanned aerial vehicle, and there is no need to shoot or measure a site image artificially. There is a unique way of conversion for generating a 3D model from a plane image, which facilitates processing and reference by the backend. Better scale conversion is available, real data can be obtained from the 3D model, and the accuracy of survey is improved. The method is simple to implement. Roof can be surveyed, and dead angles can be measured. Potential safety hazard caused by artificial survey is avoided.

Description

technical field [0001] The invention relates to a survey method, in particular to a drone-based power station site survey method. Background technique [0002] As far as existing technologies are concerned, UAVs can be divided into military and civilian uses according to their application fields. In terms of military use, UAVs are divided into reconnaissance aircraft and target aircraft. In terms of civilian use, drones + industry applications are the real rigid needs of drones; currently, they are used in aerial photography, agriculture, plant protection, selfies, express delivery, disaster rescue, wildlife observation, infectious disease monitoring, surveying and mapping, news reports, and power inspections. Applications in fields such as disaster relief, film and television shooting, and romance manufacturing have greatly expanded the use of drones themselves. Developed countries are also actively expanding industry applications and developing drone technology. [0003]...
