Abstract: This application discloses a method for processing three-dimensional data. The method may be applied to the field of intelligent driving. The method includes: for a target convolution operator in a convolutional neural network, a corresponding intermediate result may be first calculated by using one or more background values of three-dimensional data; then, when first data is processed, a corresponding intermediate result may be searched for based on a background identifier in a sparse distribution diagram; and further, a value of a voxel of second data is obtained based on the intermediate result, with no need to repeat a process of convolution processing for a plurality of times, thereby implementing convolution acceleration.
