Embodiment

[0023] Please refer to figure 1 , the present embodiment provides an aircraft engine defect identification system based on real-time analysis of hole detection images, including:

[0024] The hole detection video acquisition module is used to collect the video images of the combustion chamber, compressor, high and low pressure turbine and other equipment components in the process of the aircraft engine hole detection operation in real time. Each frame of screenshot data is compressed and encoded by H.265 into a high-definition video with a resolution of 1920*1080 and 60 frames, and the continuous frame screenshots are transmitted to the image processing engine in real time according to the OTG transmission protocol format; the present invention adopts the hole detector and DP real-time Video collector, used by maintenance personnel during operation.

[0025] The image processing engine is connected to the hole detection video acquisition module to obtain continuous frame scre...

Abstract

The invention provides an aircraft engine defect identification system based on borescope image real-time analysis. The method is characterized by comprising the following steps: a borescope video acquisition module acquires a video image of an internal structure of an aircraft engine equipment part and transmits the video image to an image processing engine in real time; the image processing engine automatically recognizes defects such as cracks, pits, burns, notches, deformation, corrosion and material loss of the aircraft engine equipment component in each frame of video image in real time through a neural network image recognition analysis algorithm, and transmits a defect recognition analysis result to a data background; the data background is used for matching defect identification results found by the image processing engine with records in an aircraft engine defect index database, and confirming and recording defects and change trends; the system achieves the real-time tracking and monitoring of the defect state of an aircraft component, automatically learns and accumulates a defect feature database, carries out the precise recognition and quick verification of defects, and promotes the application and development of an intelligent maintenance and inspection technology in the field of aircraft operation and maintenance.

Description

technical field [0001] The invention relates to the aircraft route operation and maintenance industry, in particular to an aircraft engine defect identification system based on real-time analysis of hole-probing images. Background technique [0002] At present, the aircraft engine maintenance inspection adopts the endoscope camera and display screen of the hole detector, and the whole process of manual visual observation is used to check the equipment components in different areas inside the aircraft engine one by one, such as the combustion chamber, compressor, high and low pressure turbine, etc. for cracks, concave, etc. Defects such as pits, burns, nicks, deformation, corrosion, material loss, etc. Because the appearance of the equipment parts to be inspected is similar, and some defects are not obvious, the visual manual inspection method has the problems of missed inspection and inability to track the trend of defect changes in real time, thus posing a hidden flight saf...
