The invention provides an incomplete detection method and device. The incomplete detection method comprises the steps of obtaining a plurality of two-dimensional images only comprising a to-be-detected object from a plurality of remote sensing images for the same to-be-detected object; performing feature point matching on every two two-dimensional images to obtain a plurality of feature point pairs; generating a three-dimensional image of the to-be-detected object according to the plurality of feature point pairs corresponding to every two two-dimensional images; performing registration fusionon the plurality of three-dimensional images to obtain a target three-dimensional image of the to-be-measured object; obtaining a test distance between at least one group of test points in the targetthree-dimensional image; and determining whether the to-be-tested object at the position corresponding to the test point is incomplete or not according to the difference between the test distance anda preset standard distance. According to the incomplete detection method, the whole detection process is automatically executed by a computer, so that the manpower is saved, and the detection precision is improved, and the probability of misjudgment and missed judgment is greatly reduced.
Description
technical field [0001] The invention belongs to the technical field of remote sensing images, in particular to a defect detection method and device. Background technique [0002] The transmission line is mainly responsible for the transmission of electric energy, which plays a vital role in the safe and reliable operation of the power grid and directly affects the stable development of the national economy. However, since most transmission lines are exposed to the natural environment, they experience external environmental damage such as wind and sun, rain and snow, lightning strikes, pollution migration and subsidence, and also need to withstand the internal pressure of mechanical loads. The above factors will cause the components of the transmission line to age or even be damaged to varying degrees. If the hidden dangers in these transmission lines cannot be discovered and eliminated in time, it may bring great harm to the transmission link and pose a serious potential thr...
