1. A face image processing method, performed by a payment processing server, the method comprising:
obtaining a plurality of lattice depth images acquired by performing a depth image acquisition on a target face from different acquisition angles;
converting each of the plurality of lattice depth images into a point cloud image, to obtain a plurality of point cloud images;
performing a fusion processing on the plurality of point cloud images to obtain a dense point cloud map;
converting the dense point cloud map into a dense lattice depth image; and
performing a face recognition processing on the dense lattice depth image to obtain a face recognition result.
