Embodiment 1

[0045] The first step is to collect solar panel image samples and data processing:

[0046] Collect image samples of solar panels and divide them into qualified samples and defect samples. Defect samples include defect samples with solid black, hidden cracks, broken grids, shadows and open welding defects. When the qualified sample data is more than the defective sample data , it is necessary to resample the solar panel image sample data set, that is, to perform data enhancement on less defective sample data by zooming, shifting, flipping, changing the brightness of the picture, and adding Gaussian noise after mean filtering, and for a large number of qualified samples The data randomly deletes a part of the image sample data to balance the collected solar panel image sample data, thereby completing the collection of solar panel image samples and data processing;

[0047] figure 1 It shows that the types of solar panel image samples collected in this embodiment include quali...

[0072] Except that in the second step of solar panel image preprocessing, the finally obtained training sample set has 2800 samples, and the test sample set has 1000 samples, other steps are the same as in embodiment 1.

Embodiment 3

[0074] Except that in the second step of solar panel image preprocessing, the finally obtained training sample set has 3200 samples, and the test sample set has 1400 samples, other steps are the same as in embodiment 1.

Abstract

The invention discloses a solar cell panel defect detection method based on a multi-scale joint convolutional neural network. General image data processing of a neural network is involved. Firstly, asolar cell panel image sample is collected and data is processed; balancing the sample and then carrying out pretreatment operation; dividing the processed various types of images into a training setand a test set; building an experiment software environment and an experiment hardware environment after the data set is obtained; constructing a multi-scale joint convolutional neural network model;inputting the marked training set into the model for learning; and the test set is used for testing to complete the detection of the defects of the solar cell panel, so that the defects of single function, weaker generalization ability, incapability of ensuring the accuracy in an actual detection task, difficulty in universality of a set of parameters, fewer detectable categories, larger calculated amount and lower efficiency in the prior art of the defect recognition or detection method of the solar cell panel are overcome.

Description

technical field [0001] The technical proposal of the present invention relates to the general image data processing of neural network, in particular to the solar cell panel defect detection method of multi-scale joint convolutional neural network. Background technique [0002] With the development of society, the demand for green energy continues to increase. Due to the renewable, clean and pollution-free features of solar energy, the photovoltaic industry has developed rapidly, and solar panels are the core components of energy conversion, and their output is also rising. The battery board may be damaged during the process of production, transportation, installation and use. These defects caused by damage will seriously reduce the photoelectric conversion efficiency and service life of the solar panel. Therefore, it is necessary to detect the defect of the solar cell panel in time before using it, and replace the defective solar cell panel. In recent years, with the matu...
