Embodiment 1

[0066] Examples of the present invention is applied for target identification transmission towers and insulators and the automatic head position tracking are described below:

[0067] figure 1 UAV is a method and system for inspection of module power a block diagram. The system includes a dual-spectrum video acquisition module, an image processing module, a dual mode video output module and a communication module. By dual-spectrum video capture module respectively by the visible light CCD and ICCD ultraviolet visible light image and the ultraviolet image acquisition corona discharge into the system (via the video capture module bis spectrum visible light by the visible light CCD image acquisition into the system by the double UV spectra of the video capture module ICCD corona discharge generates ultraviolet image acquisition into the system), to give the processed video image after the image processing module, the final video output dual mode module is divided into two, to transm...

Embodiment 2

[0076] The present invention is applied to an example of an abnormal discharge position detection of an insulator abnormally, as follows:

[0077] figure 1 Module of the module of the unmanned electric power inspection method and the system. The system includes a dual-spectral video acquisition module, an image processing module, a dual mode video output module, and a communication module. The ultraviolet image generated by visible light image and corona discharge generated by visible light CCD and ultraviolet light ICCD, respectively, and the image processing module is obtained, and finally dual mode video output module is obtained after the image processing module. Divided into two, all the way to the liquid crystal screen for visual output, and the other passes through the communication module to be encoded in a stream form.

Abstract

The invention discloses an unmanned aerial vehicle-mounted power inspection method and system based on embedded and dual-spectrum imaging. The system comprises a dual-spectrum video acquisition module, an image processing module, a dual-mode video output module and a communication module; visible light images and ultraviolet light images generated by corona discharge are collected into the system by a visible light CCD and an ultraviolet light ICCD through the double-spectrum video acquisition module, processed video images are obtained through the image processing module, finally, the processed video images are divided into two paths through the double-mode video output module, one path is transmitted to a liquid crystal screen to be visually output, and the other path is coded by the communication module and then is pushed in a code stream form. According to the invention, abnormal corona discharge position detection of an insulator and target identification of the insulator and a power transmission tower are realized, pose information can be transmitted, sensor information can be received, video files can be stored, and the problems of low inspection efficiency and high risk in a traditional electric power inspection method are solved.

Description

Technical field [0001] The present invention belongs to the field of electrical inspection, and more particularly to an embedded double-based spectral imaging UAV electrical inspection methods and systems. Background technique [0002] Perennial subjected to high voltage transmission line due to various natural conditions, prone to aging, damaged insulators, etc., thereby generating abnormal electrical discharge transmission line. In the field of power inspection, a common sensor includes a visible light camera, an infrared imager, imager UV space and scanners. Wherein a visible light camera is often used to identify defects visible or target shooting. Infrared camera is used to power line conductors, insulators and other infrared imaging target, characterized by a heat distribution is analyzed to determine the temperature of the target is within a normal range. The ultraviolet imager for capturing an abnormal discharge conditions on cables, fittings and other parts of the insula...
