[0070] VGG convolutional neural network model reference figure 1 , mainly composed of input layer, convolutional layer, pooling layer, fully connected layer, and Softmax layer. VGGNet can be divided into 5 layer groups, including Conv1 convolutional layer group 1, Conv2 convolutional layer group 2, Conv3 convolutional layer group 3, Conv4 convolutional layer group 4 and Conv5 convolutional layer group 5, fully connected layer including FC6 Fully connected layer 6 and FC7 fully connected layer ...

Embodiment 2

[0077] A kind of recognition method of bamboo forest pests based on the convolutional neural network model of this embodiment, based on embodiment one, collects the image data of different growth stages of bamboo forest pests, for example, collects the image data of pests from eggs to larvae to adult stages, for training The model avoids the error in model detection caused by the large difference in the body characteristics of pests in different growth stages. Of course, the types of pests are different and the growth stages of pests are different. In addition, the color of the bamboo forest pest sample image is retained according to the situation, because the pest not only has differences in shape and texture, but color is also an important factor affecting the recognition accuracy. Therefore, in the data processing process, the input image data is not converted into a grayscale image. , but retains the values ​​of the RGB three color channels of the image.

Embodiment 3

[0079] A kind of bamboo forest pest recognition method based on convolutional neural network model of the present embodiment, based on embodiment two, bamboo forest pest sample image data is processed, obtains the bamboo forest pest sample image data set after processing, comprises the following steps:

[0080] Handle erroneous and repeated data in the image data of bamboo forest pest samples;

[0081] The image data of bamboo forest pest samples are expanded by means of data augmentation.

[0082]Expand the sample image data of bamboo forest pests by means of data enhancement: After screening, the number of samples of each insect is different. In order to improve the classification accuracy of the network, make the performance of the network better, and prevent problems such as overfitting, this embodiment Adopt the mode of data enhancement to expand the above-mentioned bamboo forest pest sample image data amount, by operating the above-mentioned bamboo forest pest sample ima...

Description

technical field [0001] The invention belongs to the technical field of identification and classification of agricultural and forestry pests, in particular to a bamboo forest pest identification method based on a convolutional neural network model. Background technique [0002] Our country is a large agricultural country. During the cultivation of crops, different kinds of pests are encountered every year, which makes the yield and quality of crops decline to varying degrees. When the disaster is severe, it may even lead to a large area of ​​crop failure. Accurate and effective classification, identification and identification of insects is an important prerequisite for timely pest control and avoiding huge economic losses of crops. Insects are the most diverse animals in the natural environment, and it is very difficult to identify them due to their varied shapes and rich textures. Traditional insect taxonomy and identification mainly rely on insect experts or insect taxono...
