Hand-held airplane structural member surface crack detection system based on image analysis and detection method thereof

The invention relates to the technical field of optical detection, in particular to a handheld aircraft structural part surface crack detection system based on image analysis and a detection method thereof.The handheld aircraft structural part surface crack detection system comprises handheld detection equipment, a computing platform and handheld display equipment, and the specific steps are as follows: collecting picture samples to establish a data set; establishing a convolutional neural network model; training the model; model conversion; starting the system; image acquisition; preprocessing the image; identifying cracks; outputting a detection result; judging an output result; iteratively training a crack recognition algorithm; after the iterative training of the crack recognition algorithm is completed, the problems of missing detection and misjudgment caused by long visual detection time and visual fatigue during the inspection of important bearing structural members and skins during the use or repair o
