Contexte du projet<\/strong><\/em><\/span>
\nCe projet comprenait le relev\u00e9 topographique et la documentation de l'existant d'un complexe h\u00f4telier \u00e0 Bali. Situ\u00e9 dans une zone dens\u00e9ment bois\u00e9e, le complexe a fait l'objet d'un relev\u00e9 portant sur un b\u00e2timent en construction mais non encore achev\u00e9. Le client exigeait des donn\u00e9es de nuage de points de haute qualit\u00e9, adapt\u00e9es \u00e0 la v\u00e9rification de l'existant et \u00e0 la mod\u00e9lisation int\u00e9rieure, afin de fournir une base fiable pour la conception, l'am\u00e9nagement int\u00e9rieur ou la planification de la r\u00e9novation. De plus, le projet n\u00e9cessitait l'int\u00e9gration des coordonn\u00e9es int\u00e9rieures et ext\u00e9rieures par RTK ou points de contr\u00f4le pour garantir un syst\u00e8me de r\u00e9f\u00e9rence spatiale coh\u00e9rent et pr\u00e9cis.

D\u00e9fis<\/strong><\/em><\/span>
\nLa v\u00e9g\u00e9tation dense et le terrain escarp\u00e9 ont fortement perturb\u00e9 les signaux GNSS et limit\u00e9 la visibilit\u00e9 directe, rendant les lev\u00e9s RTK traditionnels peu fiables. Bien que les stations totales offrent une grande pr\u00e9cision, la complexit\u00e9 de l'environnement et les fortes pentes ont rendu l'installation, le d\u00e9placement et la mesure des instruments fastidieux et chronophages, entra\u00eenant une faible efficacit\u00e9 et un risque de non-respect des d\u00e9lais. Par ailleurs, les exigences strictes du client concernant la qualit\u00e9 du nuage de points \u2013 lignes de murs pr\u00e9cises, repr\u00e9sentation claire des structures et surfaces lisses \u2013 ont pos\u00e9 des d\u00e9fis suppl\u00e9mentaires auxquels les m\u00e9thodes topographiques conventionnelles peinaient \u00e0 r\u00e9pondre.<\/span><\/p>\n

Solution<\/strong><\/em><\/span>
\nPour r\u00e9pondre aux d\u00e9fis pos\u00e9s par un environnement complexe et aux exigences de haute qualit\u00e9 en mati\u00e8re de nuages de points, le syst\u00e8me SL9 SLAM RTK a \u00e9t\u00e9 d\u00e9ploy\u00e9. En combinant la num\u00e9risation laser SLAM et le positionnement RTK, le SL9 a permis de capturer efficacement des donn\u00e9es spatiales continues et stables, m\u00eame sous une canop\u00e9e dense et dans des conditions GNSS limit\u00e9es. Cette approche a garanti une qualit\u00e9 de nuage de points optimale pour l'ing\u00e9nierie, tout en pr\u00e9servant l'efficacit\u00e9 op\u00e9rationnelle, offrant ainsi une base fiable pour la documentation de l'existant, la mod\u00e9lisation int\u00e9rieure et les applications de conception ou de r\u00e9novation ult\u00e9rieures.<\/span>
\nFlux de travail<\/strong><\/em><\/span><\/p>\n

1. D\u00e9ploiement rapide et num\u00e9risation en une seule touche<\/p>\n

Le syst\u00e8me SL9 SLAM RTK est dot\u00e9 d'une conception int\u00e9gr\u00e9e permettant aux op\u00e9rateurs de lancer la num\u00e9risation d'une simple pression sur l'\u00e9cran. M\u00eame le personnel non sp\u00e9cialis\u00e9 peut effectuer le lev\u00e9 de mani\u00e8re autonome apr\u00e8s une br\u00e8ve formation, ce qui r\u00e9duit les co\u00fbts de main-d'\u0153uvre et de formation.<\/span><\/p>\n

2. Flux de travail de num\u00e9risation vers carte compatible RTK<\/p>\n

Le syst\u00e8me RTK int\u00e9gr\u00e9 permet aux op\u00e9rateurs de scanner des zones d'int\u00e9r\u00eat sans suivre de parcours stricts, offrant ainsi flexibilit\u00e9 et efficacit\u00e9 dans des environnements de b\u00e2timents complexes.<\/span><\/p>\n

3. Syst\u00e8me de coordonn\u00e9es unifi\u00e9 int\u00e9rieur-ext\u00e9rieur<\/p>\n

Dot\u00e9 d'un module RTK haute pr\u00e9cision, le SL9 garantit l'alignement des donn\u00e9es int\u00e9rieures et ext\u00e9rieures dans un r\u00e9f\u00e9rentiel spatial unique, facilitant ainsi une int\u00e9gration transparente pour la conception, la construction et la gestion.<\/span>
\nR\u00e9sultats<\/strong><\/em><\/span><\/p>\n

1. Nuages de points de haute qualit\u00e9<\/p>\n

Les nuages de points obtenus repr\u00e9sentent clairement les murs, les colonnes et les \u00e9l\u00e9ments structurels avec des surfaces lisses et un minimum de bruit, refl\u00e9tant fid\u00e8lement l'\u00e9tat actuel du b\u00e2timent.<\/span><\/p>\n

\"Cartographie<\/p>\n

\"Cartographie<\/p>\n

2. Mesure et quantification rapides<\/p>\n

\u00c0 partir du nuage de points, les op\u00e9rateurs peuvent rapidement calculer le p\u00e9rim\u00e8tre, la surface au sol et le volume d'un b\u00e2timent, facilitant ainsi les lev\u00e9s topographiques, la v\u00e9rification des constructions et la gestion de projets tout en minimisant les visites r\u00e9p\u00e9t\u00e9es sur site.<\/span><\/p>\n

3. D\u00e9coupage de nuages de points et int\u00e9gration CAO<\/p>\n

Les donn\u00e9es peuvent \u00eatre import\u00e9es dans un logiciel SAT-LiDAR pour le d\u00e9coupage, l'extraction pr\u00e9cise des lignes de paroi et des limites structurelles. Le r\u00e9sultat vectoris\u00e9 s'int\u00e8gre facilement dans un logiciel de CAO pour le dessin, le m\u00e9tr\u00e9 et l'analyse technique, compl\u00e9tant ainsi un flux de travail enti\u00e8rement int\u00e9gr\u00e9, de l'acquisition sur site \u00e0 la documentation du projet.<\/span><\/p>\n
