However, the current available object detection systems are not well-optimised for construction applications, due to the tedious setups incorporated for referencing an object to a system and inability to cope with the elements imperfections. In this paper, we propose a flexible object pose estimation framework to enable robots to autonomously handle building components on-site with an error tolerance to build a specific design target without the ne","authors_text":"Mohamed Dawod, Sean Hanna","cross_cats":["cs.CV"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.RO","submitted_at":"2019-08-22T05:44:08Z","title":"BIM-assisted object recognition for the on-site autonomous robotic assembly of discrete structures"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1908.08209","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:da3753e7408fd7fd2882c3d6bcd011a25b8f86f245a0ff0261bdd807fba789b8","target":"record","created_at":"2026-07-04T23:59:10Z","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":"a1e9bbc72a6ba1f15b8d55e239be05f48c0ceb16780c277b0ccc107b34a82e80","cross_cats_sorted":["cs.CV"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.RO","submitted_at":"2019-08-22T05:44:08Z","title_canon_sha256":"fdaaec057a43d59279fb431bdb7d0a7f93190922b61d84583f631c05feeb1d93"},"schema_version":"1.0","source":{"id":"1908.08209","kind":"arxiv","version":1}},"canonical_sha256":"1512420e8e3863bb2c63ea6f35422ab2cc55f22eea432bb49b39b7dd58636e9e","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"1512420e8e3863bb2c63ea6f35422ab2cc55f22eea432bb49b39b7dd58636e9e","first_computed_at":"2026-07-04T23:59:10.609013Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-04T23:59:10.609013Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"jl9WZDkfa3QDluVQy1L+Q0sMyF7iMOA9F4VS80yndgg0FPIztL4j7zi6fyWjbLTKKVFV+YqnErbqMTWgtyZ6Cw==","signature_status":"signed_v1","signed_at":"2026-07-04T23:59:10.609371Z","signed_message":"canonical_sha256_bytes"},"source_id":"1908.08209","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:da3753e7408fd7fd2882c3d6bcd011a25b8f86f245a0ff0261bdd807fba789b8","sha256:c3a9dce74dfd70318317bfaee75be7954066b8bc4f0c3069cf677353106c43ee"],"state_sha256":"3521c46c75a585961f64848c4fa8fe2eb7d273bde5161d01bd79b8a73c14e0de"}
