Video image fusion method based on wind turbine generator fault identification

Abstract

The invention provides a video image fusion method based on wind turbine generator fault identification. The method comprises the following steps: collecting video image information of a wind turbinegenerator; performing image framing processing on the video image information; carrying out gray scale conversion on the image after framing processing,and carrying out pixel-level image fusion underwavelet decomposition to obtain a first fusion image; performing pixel-level image fusion under a Laplace pyramid on the image after framing processing to obtain a second fused image; adopting an SIFTalgorithm for the framed image to obtain a third fused image under a feature level; carrying out entropy, joint entropy and root-mean-square error calculation on the three fused images; designing a GUI human-computer interaction interface, reflecting the three fusion processing algorithms and the calculation of the index quantity in the interface, obtaining a final fusion image through the obtained index value, and carrying out the fault recognition of the wind turbine generator through the final fusion image. The fault state of the fan external equipment can be better recognized, and the influence of a shelter at a single angle is avoided.

Description

technical field [0001] The disclosure belongs to the technical field of wind turbine fault identification, and in particular relates to a video image fusion method based on wind turbine fault identification. Background technique [0002] The safety of external equipment of wind power equipment is not only to effectively deal with the formation and outbreak of crisis, but more importantly, to predict and warn the possible factors of wind power accidents, so as to fundamentally prevent the formation and outbreak of crisis. The external equipment of wind turbines must adhere to the principle of combining prevention and emergency, and special attention should be paid to the system's ability to predict and identify in advance. It is beneficial to do a good job in strengthening the basic work of preparation, preparation and early warning of emergency management of crisis events, improve the ability of early warning and prevention of crisis events, and fully realize the organic com...

Problems solved by technology

Because the video has the continuity that a single image does not have, the video image has a huge amount of information, and it has the ability of spatial resolution and time resolution at the same time, but it is complicated and difficult to really extract and dig out this information
