基于引导优化的立体匹配网络
Guided refinement for stereo matching network
摘要
Abstract
Numerous challenges exist in achieving high-precision stereo matching for intricate areas,such as small structures and edge regions.To address the issue of fine stereo matching in detailed areas,we propose a stereo matching network based on guided refinement is proposed.Firstly,a guided refinement module is con-structed,utilizing guided deformable convolution.Unlike deformable convolution,this module performs off-set and modulation scalar learning on additional input guide features to enhance the deformation parameter learning ability of deformable convolution.Secondly,a guided refinement stereo matching network is de-signed based on the guided refinement module.This network introduces a three-level cascaded cost aggrega-tion module,incorporating 3D cost aggregation and 2D guided refinement aggregation,progressively refining the registration accuracy of detailed region.Experimental results demonstrate that,compared with state-of-the-art algorithms on standard datasets such as SceneFlow and KITTI,the proposed algorithm achieves high-precision registration of detailed regions.Notably,the applicability test results of the guided refinement mod-ule on the KITTI2015 datasets indicate that the D1-noc and D1-all values of advanced algorithms such as Gw-cNet and AANet increase by approximately 20%after integrating the guided refinement module.关键词
