specific Embodiment

[0039] A neural network-based spray feature extraction method of the present invention, its flow chart is as follows figure 1 Two steps are shown. The first step is to train the model. First obtain the spray image and the corresponding working condition information. In this example, the size of the spray image is 400*400, the image is a grayscale image, that is, the number of channels of the image is 1, and the working condition information is the pressure and temperature of the spray.

[0040] A new image matrix is ​​formed by compounding the spray image and the spray working condition information, and the compound method adopts image interpolation and expansion methods. In this example, the column is used as the insertion object. Combine pressure and temperature into one sequence. In this example, the pressure is 2 digits, and the temperature is 3 digits. Put the pressure in the front and the temperature in the back, and the combination is 5 digits. Since the size of th...

Abstract

The invention relates to a spraying feature extraction method and device based on a neural network, and a storage medium. The method comprises the steps of 1, training a convolutional neural network,2, reading a model, and inputting a spray image. The method specifically comprises the steps of: 1, acquiring a spray image, forming a new composite matrix by combining working condition information and the spray image, acquiring a spray feature label, and inputting the new image matrix and the label into a neural network to obtain a structure weight under a specific neural network; and 2, readingthe model in the step 1 to obtain a spray image, compounding the spray image and the working condition information into a new image matrix, and inputting the new composite spray image into the modelto obtain spray characteristics. The invention creatively provides the method for compounding the spray image and the working condition information into the new image matrix, the method well highlights the influence of the spray working condition on the spray, the feature extraction result is more closely related to the working condition, the credibility is high, and the error is small.

Description

technical field [0001] The invention relates to the field of spray and computer technology, in particular to a neural network-based spray feature extraction method, device and storage medium. Background technique [0002] Aerosolology has become an international research field. Because of its wide range of applications, it can be applied to spray combustion, cleaning sensors, cleaning glass, from rocket spray, car spray to spray in home life, the application of spray is far beyond people's imagination. Therefore, it is extremely important to study spray characteristics, which include spray area, spray penetration distance, spray cone angle, etc. [0003] Now for the extraction of spray features, there is no uniform method and no convenient tool. And rely on high-precision tools such as high-speed cameras, Malvern particle size observers, etc. So how to extract spray features conveniently and quickly is a big problem at present. Today's computer vision technology is boomi...
