In correspondence-based point cloud registration, matching correspondences by point feature techniques may lead to an extremely high outlier ratio. Current methods still suffer from low efficiency, accuracy, and recall rate. We use a simple and intuitive method to describe the 6-DOF (degree of freedom) curtailment process in point cloud registration and propose an outlier removal strategy based on the reliability of the correspondence graph. The method constructs the corresponding graph according to the given correspondences a","authors_text":"Hao Wu, Hong Xie, Jicheng Dai, Li Yan, Ming Huang, Pengcheng Wei","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2022-05-16T00:37:57Z","title":"A New Outlier Removal Strategy Based on Reliability of Correspondence Graph for Fast Point Cloud Registration"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2205.07404","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:14d2f07af1650fb94dc8f3ebb015c7ed873950600a476795d1deab3154780c7b","target":"record","created_at":"2026-07-05T09:26:13Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"415ab137537ad150e5939f1932b4ddfb60fbe71a625aa9663115a858fd85eb31","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2022-05-16T00:37:57Z","title_canon_sha256":"96073ecf4a0faa2509a26be1db7e5c694a2bc1a886cae0afcf8bccb2ba3007a5"},"schema_version":"1.0","source":{"id":"2205.07404","kind":"arxiv","version":1}},"canonical_sha256":"f92a69dd447dd76e5e607ecba63944c411d5d1e55777c455f47f0c32a83274ba","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"f92a69dd447dd76e5e607ecba63944c411d5d1e55777c455f47f0c32a83274ba","first_computed_at":"2026-07-05T09:26:13.959776Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T09:26:13.959776Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"NBvxTWE66Ye4e9rHLbVfZtNzCsaC/hmbYs6U6cRlhoX5fC8jmUYVBfqoPmeN5JXg11NsXbfb7kn9m1agw4AvAA==","signature_status":"signed_v1","signed_at":"2026-07-05T09:26:13.960301Z","signed_message":"canonical_sha256_bytes"},"source_id":"2205.07404","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:14d2f07af1650fb94dc8f3ebb015c7ed873950600a476795d1deab3154780c7b","sha256:f659bd98c8789d2d99ae30da9367ddbfa147642c8d59d0cc9d27878bf657cbb2"],"state_sha256":"843e050d8d7b20a004c589d914d7a4802d567123534c2dc34c12aa49903830fc"}
