In this paradigm, all upsampling layers and refinement stage, which are indispensable in all existing point-based methods, are abandoned to reduce the large computation cost. The authors propose a fusion sampling strategy in the downsampling process to make detection on less representative points feasible. A delicate box prediction network including a candidate generation layer, an anchor-free regression head with a 3D center-ness assignment strategy is designed to meet the needs of accuracy and speed.","description_state":"present","introduced_year":null,"introduced_by":{"title":"3DSSD: Point-based 3D Single Stage Object Detector","paper":"/paper/3dssd-point-based-3d-single-stage-object","first_author":"Zetong Yang","n_authors":4,"url_abs":null,"archive_paper_url":"https://paperswithcode.com/paper/3dssd-point-based-3d-single-stage-object"},"source":{"url":"https://arxiv.org/abs/2002.10187v1","title":"3DSSD: Point-based 3D Single Stage Object Detector","url_on_a_paper_host":true},"code_snippet_url":null,"code_snippet_url_on_a_code_host":false,"categories":[{"area":"Computer Vision","area_id":"computer-vision","collection":"3D Object Detection Models","url":"/methods/category/3d-object-detection-models","pwc_aliases":[]}],"n_papers_tagged":1,"archive_num_papers":1,"papers_newest_first":[{"paper":"/paper/3dssd-point-based-3d-single-stage-object","title":"3DSSD: Point-based 3D Single Stage Object Detector","date":"2020-02-24","arxiv_id":"2002.10187","n_code_links":2,"syntology":null}],"papers_shown":1,"tasks":[{"task":"/task/object","name":"Object","papers":1}],"tasks_shown":1,"n_tasks":1,"usage_by_year":[{"year":"2020","papers":1}],"row_source":"methods_table","archive":{"source":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","archive_url":"https://paperswithcode.com/method/3dssd"},"syntology_read_at":"2026-09-24T18:15:14+00:00"}
