Method and system for tower deformation detection based on image UAV

Abstract

Embodiments of the present invention provide a method and system for detecting deformation of iron towers based on video drones. All key points of the tower, the key points are composed of the center point of the base, the center points of all cross arms and the spire. For the r-th orthographic image, determine the horizontal distance offset between the i-level key point and the j-level key point Determine the maximum value of the horizontal distance offset between the i-level key point and the j-level key point of all orthographic images as the i-level key The actual horizontal distance offset between the point and the j-level key point; based on the actual horizontal distance offset between any two key points in all key points, it is determined whether the tower to be detected is deformed. The method and system provided by the embodiments of the present invention realize the improvement of the deformation detection efficiency of the iron tower to be detected, and avoid the cumbersome on-the-spot measurement of the detection personnel.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a method and system for detecting deformation of iron towers based on image drones. Background technique [0002] In real life, the power grid needs to build iron towers, also known as pole towers. As the use time increases, the vertical iron tower will become inclined and deformed when the construction is completed. The traditional commonly used tower deformation detection methods mainly use theodolite, total station and other measuring equipment to measure the deformation of the tower. It is difficult to satisfy the work, and it is not easy to set up the instrument tripod. The light path between the instrument and the iron tower is easily obscured by trees, houses and other ground objects, resulting in poor sightlines. When measuring, it is necessary for personnel to climb the tower and set up a ruler to assist in the measurement, which greatly increases the r...
