A plethora of methods and systems have already been proposed for the acquisition of the geometry of real-life objects ranging from those which employ active sensor technology, passive sensor technology or a combination of various techniques.\n  In this paper we present the development of a 3D scanning system which is based on the principle of structured-light, without having particular requirements for specialized equipment. We discuss the intrinsic details and inherent difficulties of struc","authors_text":"Charalambos Poullis, Kyriakos Herakleous, Qing Gu","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2014-06-25T14:51:21Z","title":"3DUNDERWORLD-SLS: An Open-Source Structured-Light Scanning System for Rapid Geometry Acquisition"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1406.6595","kind":"arxiv","version":2},"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":"sha256:44b8d02a584892cb3839028d2f6af7ce5d933f0d234f8413ae2cff459a7c7443","target":"record","created_at":"2026-05-18T01:08:27Z","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":"b0e2772188fc251fccce6699394d6b620a302171f9c600fffab9b41461f6a156","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2014-06-25T14:51:21Z","title_canon_sha256":"f6257371c737259c0d831a739560d384afbf14c151425c3a01e571c16a55c53d"},"schema_version":"1.0","source":{"id":"1406.6595","kind":"arxiv","version":2}},"canonical_sha256":"9cf140f57c7d43a0bbd8cfbf8087aecf9b5d514748f5bdcd9b64342926c35cac","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"9cf140f57c7d43a0bbd8cfbf8087aecf9b5d514748f5bdcd9b64342926c35cac","first_computed_at":"2026-05-18T01:08:27.533614Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:08:27.533614Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"7agObBjNrTB/8a4wcC4YsliJCJxREBh65wXQHgxgamDCtt0YvGbAZijg+Y32cXwJAyvK3/gJMTc3dfbaS/KeCg==","signature_status":"signed_v1","signed_at":"2026-05-18T01:08:27.534076Z","signed_message":"canonical_sha256_bytes"},"source_id":"1406.6595","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:44b8d02a584892cb3839028d2f6af7ce5d933f0d234f8413ae2cff459a7c7443","sha256:00f5d22c846df15fabc8ec84f02ca9281a997d52b8ffa4a74804a43580c9e1e9"],"state_sha256":"d3fcc734aed289af51555e60b059566f21d301ead1ce895d6cf9f3ac854d433d"}
