Evaluation of the State of Objects by Unmanned Aerial Vehicles

Abstract

The problem of protection and evaluation of the state of objects is considered in the paper. The advantages of using unmanned aerial vehicles for protection and assessment of the state of the objects are presented.

It can be adequately measured the status of objects by using operations such as filtering, contour selection, alignment, selection of image objects, skeleton, color definition and image intensity as outlined in the work. These operations, especially in the complex, allow improving the overall processing of images obtained using unmanned aerial vehicles.

The main features of unmanned aerial vehicles are considered, which allow monitoring the status of objects with their further evaluation. These include tactical; small or medium-sized; small, medium or long flight duration; not very high; with an airplane or helicopter aerodynamic scheme; ground or sea based; military or civilian; horizontal or vertical lift / landing; multiple and wide range of radius.

The structural scheme is developed and the algorithm of the unit of monitoring of an unmanned aerial vehicle for estimation of the state of objects with the subsequent possibility of upgrading due to the improvement of component parts is given. The main components of the monitoring block are considered, namely, the main controller, video camera, power module, stabilization sensors, bridge controller, half-bridge drivers, FPV module, which also consists of the FPV module video camera, transmitter, antenna and power module. The main parameters and functions of the components of the monitoring block are given, and possible analogues for the main components are proposed, namely the video camera and the main controller.

In the example of the original image, operations are carried out to evaluate the state of objects on the image obtained by the unmanned aerial vehicles, and analyze the result of their work.
