Abstract：Aiming at the problem of human identity and motion recognition, a method based on low resolution infrared array sensor and using convolutional neural network for classification and recognition is proposed, which can identify the identity of people and actions of falling, sitting and walking. The convolutional neural network used in this paper is based on VGGNet. It consists of input layer, five-layer convolutional layer, three-layer pooling layer, one layer of fully connected layer and output layer. It automatically extracts information features in infrared thermal images, and classifies actions, avoids the cumbersome manual extraction features under good privacy protection. After experimental testing, the average accuracy of convolutional neural network algorithm recognition is 93.3%, of which the walking recognition accuracy rate is 100%, the sitting recognition accuracy is 90%, the fall recognition accuracy is 90%, and the identity recognition accuracy is 96.7%.
