Embodiment 1
[0079] refer to figure 1 The shown schematic diagram of a hidden danger target analysis method based on aerial images, the specific steps of the present invention are implemented as follows:
[0080] Step S101, acquiring visible light images through aerial photography during inspection;
[0081] During the inspection process of drones or helicopters, a suitable photoelectric pod can be designed to carry the required load equipment and visible light cameras for flight tasks. At the same time, inspection tasks can also be arranged to collect known information in the inspection area, including the number of poles and towers.
[0082] Step S102, in the visible light image, identify the target image containing the tower pole;
[0083] Since a large amount of image data will be obtained during the inspection process, through the screening of tower pole data, images that do not contain tower poles can no longer be processed, reducing a large number of analysis tasks.

Embodiment 2
[0130] Corresponding to the method provided in Embodiment 1, this embodiment also provides a hidden danger target analysis system based on aerial images, such as figure 2 As shown, it is a diagram of the module composition of the system, including:
[0131] Visible light camera 201, used to obtain visible light images by aerial photography during inspections;
[0132] A tower image screening module 202, configured to identify target images containing towers in the visible light image;
[0133] The insulator string detection module 203 is used to detect the insulator string in the target image containing the pylon;
[0134] A hidden target detection module 204, configured to detect hidden targets in the region of the target image above the insulator string;
[0135] The hidden danger object analysis module 205 is used to analyze the impact of the insulator string flashover on the detected hidden danger object.
[0136] In the scene of power inspection, hidden dangers are mo...

Abstract
The invention discloses an aerial-image-based hidden-danger target analysis method and system. The method comprises: a visible light image is obtained by aerial shooting during routing inspection; a target image containing a pole is identified in the visible light image; an insulator chain is detected in the pole-contained target image; a hidden danger target is detected in an area, above the insulator chain, of the target image; and an insulator flashoverinfluence analysis is carried out on the detected hidden danger target. According to the technical scheme, the pole-contained target image is identified and is selected; on the basis of the screened target image, the detection and analysis of the hidden danger target are realized based on the insulator chain detection, thereby carrying out rapid screening on lots of routing inspection aerial images and improving the hidden danger target identification and analysis efficiency. Compared with the prior art, with the method and system, the identification and analysis accuracy and efficiency of the hidden danger target are substantially improved.
Description
technical field [0001] The invention belongs to the technical field of helicopter power patrol inspection, and in particular relates to a hidden danger target analysis method and system based on aerial images. Background technique [0002] As the application of unmanned aerial vehicles / helicopters in the field of power inspection has been more and more recognized, the traditional task is issued by the leader in writing, and the inspectors rely on experience and memory to inspect along the transmission line, use paper records, and return The inspection mode that is sorted out by a special person is changing. There are some disadvantages in the traditional inspection method, such as: high labor cost and long inspection time; inspection is manually recorded, and there is a certain degree of subjectivity in the analysis of hidden dangers in transmission lines; Useful for statistical analysis, etc. [0003] At present, the technology of drones equipped with visible light camera...
