CONVOLUTIONAL NEURAL NETWORK-BASED IMAGE PROCESSING METHOD AND DEVICE, AND UNMANNED AERIAL VEHICLE

摘要

Convolutional neural network-based image processing method and device are provided. The device includes a first on-chip memory and an arithmetic circuit configured to read a 3D feature map from a first on-chip memory by blocks the 3D feature map being divided into L blocks, perform processing of the current layer of the convolutional neural network on the 3D feature map by blocks; and store an output result of the current layer to the first on-chip memory. The first on-chip memory includes: S first storage spaces, each being used to store one of the L blocks included in the 3D feature map as input data of the current layer; and R second storage spaces, each being used to store output data of the current layer of one of the L blocks. L, S and R are integers greater than 1, and S and R are less than L.
