Methods for automatic 3D urban building modeling typically employ multi-view images as input to algorithms to recover point clouds and 3D models of buildings. However, such models rely heavily on multi-view images of buildings, which are time-intensive and limit the applicability and practicality of the models. To solve these issues, we focus on designing an efficient DSM estimation-driven reconstruction framework (Building3D), which aims to reconstruct 3D bu","authors_text":"Deke Tang, Kaiqiang Chen, Kun Fu, Liangjin Zhao, Wei Chen, Wenhui Diao, Wenjie Liu, Xian Sun, Yongqiang Mao, Zhirui Wang","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2023-01-11T17:20:30Z","title":"Elevation Estimation-Driven Building 3D Reconstruction from Single-View Remote Sensing Imagery"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2301.04581","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:a64b854ee3359f793a304abe0fb4588e302d5e330ba34082ae6a49a7d05213ed","target":"record","created_at":"2026-07-05T06:32:04Z","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":"aa63ca64f121326e7beb65065bc03927b9e102b80bc5a876e9d4c78857ea83e2","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2023-01-11T17:20:30Z","title_canon_sha256":"0e4093b5946f4b7b67c79609221c565b4bc1174efaa6740610d0db7365933855"},"schema_version":"1.0","source":{"id":"2301.04581","kind":"arxiv","version":1}},"canonical_sha256":"af6e312392ac9727a680588b1dda7bee5afaaa446e0019e4aa2c1caaddaa8d1e","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"af6e312392ac9727a680588b1dda7bee5afaaa446e0019e4aa2c1caaddaa8d1e","first_computed_at":"2026-07-05T06:32:04.935532Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T06:32:04.935532Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"CRt+ceKmIgI2eAuHukgwkivdQ2O8Wc2EGLG+rUMnh62iUZF75O0Nbqo4E3fND84dgYz/FE6bzO4y/g52R+uAAg==","signature_status":"signed_v1","signed_at":"2026-07-05T06:32:04.936035Z","signed_message":"canonical_sha256_bytes"},"source_id":"2301.04581","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:a64b854ee3359f793a304abe0fb4588e302d5e330ba34082ae6a49a7d05213ed","sha256:53cdb4cfcbcbb4dc2c1ddbb6fee3c819b0597fb483c4409bf4814a28d58adb8c"],"state_sha256":"682f442606c7b9e13ff10d08e86f9279ec8348463af00fc81b8b3afe2e1180ad"}
