Deep neural network target detection method based on multi-scale receptive field feature fusion

Abstract

The invention relates to a deep neural network target detection method based on multi-scale receptive field feature fusion, and the method comprises the steps: collecting a training sample image whichcomprises three RGB channels, and attaching object detection box labels and the category label information of each object; converting image data and label data in the collected image data set into aformat required by training the deep convolutional neural network through preprocessing; designing a deep convolutional neural network structure based on multi-scale receptive field feature fusion; designing a deep neural network structure applied to target detection, determining an input layer and an output layer of the network according to the structure of input and output data during design, determining the number of multi-scale receptive field feature fusion modules and the number of convolution layers in the neural network, and determining the number of times of network training loop iteration and the final convergence condition of the network; and according to the structure of the trained target and model, defining a required loss function, and in the training stage, carrying out regression on the category of the target and the offset of the detection frame.
