Embodiment 1

[0063] like figure 1 As shown, this embodiment provides a technical solution: a deep learning-based terahertz image recognition method, including the following steps:

[0064] S1: Design and train a convolutional neural network

[0065] Design a convolutional neural network, the backbone network structure of the convolutional neural network is the VGG16 network structure, and replace the fully connected layer of the VGG16 network structure with a convolutional layer, and add four convolutional layers to form the convolutional neural network. Network structure, and then train the convolutional neural network to obtain the weight file of the convolutional neural network;

[0066] S2: Detect dangerous target information in terahertz raw images

[0067] Receive the original terahertz image, use the weight file formed by the training of the convolutional neural network to detect the dangerous target in the original terahertz image, and obtain the information of the dangerous targ...

Embodiment 2

[0107] The terahertz image recognition method based on deep learning in this embodiment mainly includes two parts: a convolutional neural network and a structured detection target sequence.

[0108] like figure 2 As shown, it is a block diagram of the overall process of target detection. The overall process of target detection is as follows: collect a large number of terahertz original images formed by the detection equipment, first undergo image preprocessing, send them to the convolutional neural network for training, and obtain the weight file of the network; Load the weight file of the network in the detection device to detect dangerous targets on the original terahertz image; when the detection device is in use, receive the original terahertz image transmitted by the device, and the weight file formed by the convolutional neural network The dangerous target in the Hertz original image is detected; the detected target information, through the target information structurin...

Description

technical field [0001] The present invention relates to the technical field of terahertz image recognition, in particular to a method and system for terahertz image recognition based on deep learning. Background technique [0002] Terahertz wave is a kind of electromagnetic wave, and the human body also emits electromagnetic waves in the terahertz band. Through certain technical means, the terahertz wave emitted by the human body is detected, and the detected image is processed to form a terahertz image. [0003] At present, due to its advantages of no radiation, non-contact, and non-stop, terahertz human body security inspection is more and more popular among customers and accepted by the general public in the security inspection industry. Due to the special imaging principle of terahertz images, which are very different from optical images, users without certain training cannot obtain effective information. [0004] Due to the special imaging principle of terahertz equip...
