Embodiment Construction

[0039] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0040] Such as figure 1 , the present invention provides a method for evaluating the flight accuracy of an unmanned aerial vehicle inspection system for overhead transmission lines, the method comprising the following steps:

[0041] Step 1: Check and calibrate the measuring equipment;

[0042] Step 2: Arrange signs on the drone body;

[0043] Step 3: After the UAV takes off, the measuring equipment measures the body of the UAV;

[0044] Step 4: Real-time analysis of the position of the drone;

[0045] Step 5: Evaluate the flight accuracy of the UAV inspection system.

[0046] In the step 1, first arrange the three-dimensional calibration field, use the measuring equipment to shoot the three-dimensional calibration field, so that the three-dimensional calibration field occupies the entire image; then use the direct transformation method to solve the probl...

Abstract

The invention provides a method for accurately evaluating flight of a UAV (unmanned aerial vehicle) inspection system of an overhead transmission line. The method comprises the steps of checking a measuring device; arranging markers on an UAV body; measuring the UAV body through the measuring device after the UAV takes off; analyzing the position of the UAV on real time; accurately evaluating the flight of the UAV inspection system. According to the method, the flight position and posture of the UAV body are measured to accurately evaluate the flight; the qualified UAV inspection system is screened, and the safety of devices in the line is ensured.

Description

technical field [0001] The invention relates to an evaluation method, in particular to a flight accuracy evaluation method of an unmanned aerial vehicle inspection system for overhead transmission lines. Background technique [0002] In the power system, drones are mainly used to inspect the transmission line equipment body and channel corridors, and detect equipment and channel defects. There are many types of UAVs, which can be divided into fixed-wing UAVs and unmanned helicopters according to the type. Both types have different applications in transmission line inspections. Among them, fixed-wing UAVs focus on carrying out transmission line channel inspections and disaster surveys. They can quickly discover hidden dangers such as fixed or mobile operations, wildfires, and illegal buildings in the channel. In disaster situations, they can quickly determine the scope of the disaster. Disaster situation. Unmanned helicopters focus on carrying out single-tower or section in...
