Claim 0:
1. A method for determining a target anchor, the method comprising:
extracting a plurality of feature maps of an original image using a feature extraction network;
inputting the plurality of feature maps into a feature pyramid network to perform feature fusion to obtain a plurality of fused feature maps;
inputting the plurality of fused feature maps into a region proposal network respectively; and
using the region proposal network to implement operations as follows:
determining an initial anchor of a network head using the fused feature map based on a size of each fused feature map;
determining an offset parameter of the initial anchor based on a ratio of the size of the fused feature map to the original image;
generating a plurality of candidate anchors in different directions based on the offset parameter of the initial anchor; and
determining the target anchor from the plurality of candidate anchors.
