Shivakumar","Kartik Mohta","Bernd Pfrommer","Vijay Kumar","Camillo J.

The goal of this work is to exploit the complementary strengths\nof the two sensor modalities, the accurate but sparse range measurements and\nthe ambiguous but dense stereo information. These two sources are effectively\nand efficiently fused by combining ideas from anisotropic diffusion and\nsemi-global matching.\n  We evaluate our approach on the KITTI 2015 and Middlebury 2014 datasets,\nusing randomly sampled ground truth range measurements as our sparse depth\ninput. We achieve significant performance improvements with a small fraction of\nrange measurements on both datasets. We also provide qualitative results from\nour platform using the PMDTec Monstar sensor. Our entire pipeline runs on an\nNVIDIA TX-2 platform at 5Hz on 1280x1024 stereo images with 128 disparity\nlevels.","url_abs":"http://arxiv.org/abs/1809.07677v1","url_pdf":"http://arxiv.org/pdf/1809.07677v1.pdf","source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","licence_url":"https://creativecommons.org/licenses/by-sa/4.0/legalcode","row_kind":"abstracts"},"code_links":[{"paper_slug":"real-time-dense-depth-estimation-by-fusing","repo_url":"https://github.com/ShreyasSkandanS/stereo_sparse_depth_fusion","is_official":0,"mentioned_in_paper":0,"mentioned_in_github":1,"framework":"none","reach":null}],"tasks":[{"task_slug":"depth-estimation","task_name":"Depth Estimation"}],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"atlas_url":null,"mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
