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 target analysis method and system. The method comprises the following steps: obtaining visible images through aerial photo during the polling; recognizing a pole-containing target image in the visible images; detecting an insulator string in the pole-containing target image; detecting a hidden target in the area of the target image above the insulator string; and carrying out insulator string flashover influence analysis on the detected hidden target. According to the scheme, the pole-containing target image is recognized, the pole-containing target image is selected, and the hidden target is detected and analyzed through detecting the insulator string on the basis of the screened target image, so that fast screening can be carried out on a large number of polling aerial images, and the efficiency of recognizing and analyzing the hidden target is improved; and compared with the prior art, the scheme has the advantage that the both correctness and efficiency of recognizing and analyzing the hidden target are remarkably enhanced.
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...
