Automatic inspection method, system and device based on flight at specified height

Abstract

The invention discloses an automatic inspection method, system and device based on flight at a specified height, and the automatic inspection method based on flight at the specified height is used for an unmanned aerial vehicle. The automatic inspection method based on flight at the specified height comprises the following steps: measuring the flight height of the unmanned aerial vehicle relative to the ground, controlling the unmanned aerial vehicle to fly for a preset distance at the flight height, obtaining a visual image within the preset distance, and determining the measurement moving speed of a feature point in the visual image; and determining the actual moving speed of the unmanned aerial vehicle flying at the preset distance, and establishing a flight model by taking the flight height of the unmanned aerial vehicle relative to the ground as a target according to the actual moving speed and the measured moving speed. According to the invention, normalization and accuracy of the flight route of the unmanned aerial vehicle are realized.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to an automatic inspection method, system and equipment based on flight at a designated altitude. Background technique [0002] The development of UAV technology has brought a new way of power inspection, which has been widely used in power grids and achieved good results. Although the application of drones has brought great convenience to power inspections, it is not simply equipped with a drone, and the inspection work can be carried out smoothly. [0003] UAV power inspection has been developed to the present, and it is still in the stage of "human inspection is the main, and machine inspection is supplemented". The existing drone inspection methods face the actual signal occlusion in the inspection and maintenance work of transmission lines in mountainous and hilly areas, resulting in a small effective working distance.

AI Technical Summary

Problems solved by technology

The existing drone inspection methods face the actual signal occlusion in the inspection and maintenance work of transmission lines in mountainous and hilly areas, resulting in a small effective working distance. Manually operated drones for inspections lead to inconsistent inspection photo data standards, The data quality is uneven, and the inspection efficiency is low. However, due to the high training requirements and long cycle of flight operators, the promotion of UAV inspection operations is restricted. With the gradual increase in power operation and maintenance requirements, the inspection process is simplified. Improving the inspection efficiency has become an important topic in the development of UAVs in the field of inspections. Automation and intelligence will undoubtedly be an important direction for the development of UAVs. It is urgent to study a new UAV transmission line inspection operation and maintenance method to replace the current Manual work
