Embodiment Construction
[0016] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0017] A method for identifying fruit tree diseases and insect pests in complex backgrounds based on dilated convolutions, comprising the following steps:
[0018] Step 1: Use digital cameras and video cameras arranged in the orchard to collect images of diseases and insect pests on fruit tree leaves, scale the collected images into a uniform size format, divide the scaled images into different disease types according to categories, and add labels, Get the original training set with sample labels;
[0019] In this embodiment, the size of the image is uniformly scaled to a color image with a size of 256×256×3; since the lesion area accounts for a relatively small proportion in the entire image, the image is first cropped, and the image is cut into 4 different subimages, Mark the lesion area of the image in the sub-image respectively, use a circle to...
