AI Technical Summary

Problems solved by technology

However, there is currently no network model specifically designed for infrared image target recognition, and the convolutional neural network needs strong computing power to support image processing. In order to ensure the accuracy of image recognition, the number of parameters of the deep neural network can reach tens of millions or even billions. , the computing power of the existing on-chip processor DSP is far from meeting the requirements

Existing convolutional neural networks usually use GPUs to achieve network acceleration. However, GPU power consumption is relatively high. For example, the power consumption of 1080ti boards commonly used in deep learning is usually around 250W, which is not suitable for intelligent photoelectric information processing systems. Low power consumption requirements, therefore, in order to achieve real-time detection and recognition of infrared air targets, it is necessary to develop an intelligent photoelectric information processing system based on real-time target recognition of embedded convolutional neural networks
