Ergonomics - 3-D scanning methodologies for internationally compatible anthropometric databases - Part 2: Evaluation protocol of surface shape and repeatability of relative landmark positions (ISO 20685-2:2023)
This document establishes protocols for testing of 3-D surface-scanning systems in the acquisition of human body shape data and measurements. It does not apply to instruments that measure the motion of individual landmarks.
While mainly concerned with whole-body scanners, this document is also applicable to body-segment scanners (head scanners, hand scanners, foot scanners). It applies to body scanners that measure the human body in a single view. When a hand-held scanner is evaluated, the human operator can contribute to the overall error. When systems are evaluated in which the participant is rotated, movement artefacts can be introduced; these can also contribute to the overall error. This document applies to the landmark positions determined by an anthropometrist. It does not apply to landmark positions automatically calculated by software from the point cloud.
The quality of surface shape of the human body and landmark positions is influenced by the performance of scanner systems and humans, including measurers and participants. This document addresses the performance of scanner systems by using artefacts rather than human participants as test objects.
Traditional instruments are required to be accurate to the millimetre. Their accuracy can be verified by comparing the instrument with a scale calibrated according to an international standard of length. To verify or specify the accuracy of body scanners, a calibrated test object with known form and size is used.
The intended audience is those who use 3-D body scanners to create 3-D anthropometric databases, the users of these data, and body scanner designers and manufacturers. This document intends to provide the basis for agreement on the performance of body scanners between scanner users and scanner providers as well as between 3-D anthropometric database providers and data users.
Ergonomie - 3‑D-Scanning-Methoden für international kompatible anthropometrische Datenbanken - Teil 2: Bewertungsprotokoll der Oberflächenform und Wiederholbarkeit der relativen Positionen von Orientierungspunkten (ISO 20685‑2:2023)
Dieses Dokument legt Protokolle für die Prüfung von 3D-Körperscansystemen beim Erfassen von Körperoberflächendaten und Körpermaßen fest. Es ist nicht anwendbar für Geräte, die die Bewegung einzelner Messpunkte messen.
Obwohl dieses Dokument überwiegend auf Ganzkörperscanner bezogen ist, ist es auch auf Körperteilscanner (Kopfscanner, Handscanner, Fußscanner) anwendbar. Dieses Dokument ist anwendbar für Körperscanner, die den menschlichen Körper in einer Einzelansicht messen. Bei Auswertung eines tragbaren Scanners kann die Bedienperson zum Gesamtfehler beitragen. Bei Auswertung von Systemen, bei denen der Teilnehmer bewegt wird, können Bewegungsartefakte verursacht werden; dies kann ebenso zum Gesamtfehler beitragen. Dieses Dokument ist anwendbar für die durch einen anthropometrischen Spezialisten festgelegten Messpunktpositionen. Es ist nicht anwendbar für die durch Software aus der Punktmenge automatisch berechneten Messpunktpositionen.
Die Qualität der Körperoberflächen des menschlichen Körpers und der Messpunktpositionen wird von der Leistung des Scannersystems und den Menschen, einschließlich der Person, die die Messung durchführt, und dem Teilnehmer, beeinflusst. Dieses Dokument behandelt die Leistung von Scannersystemen unter Verwendung von Artefakten als Prüfgegenstand, anstelle von menschlichen Teilnehmern.
Herkömmliche Geräte müssen auf den Millimeter genau sein. Die Überprüfung ihrer Genauigkeit kann durch einen Vergleich des Geräts mit einer Skala entsprechend einer internationalen Norm für Längen erfolgen. Für die Überprüfung oder Bestimmung der Genauigkeit von Körperscannern wird ein kalibrierter Prüfgegenstand mit bekannter Form und Größe verwendet.
Das Dokument richtet sich an diejenigen, die 3D-Körperscanner zur Erstellung von 3D-Anthropometrie-Datenbanken erzeugen und an die Nutzer der Daten sowie Entwickler und Hersteller dieser Körperscanner. Dieses Dokument verfolgt das Ziel, die Grundlage für eine Vereinbarung hinsichtlich der Leistung von Körperscannern zwischen Scanner-Nutzern und Scanner-Lieferanten zu bieten, sowie zwischen 3D-Anthropometrie-Datenbankanbietern und Datennutzern.
Ergonomie - Méthodologies d'exploration tridimensionnelles pour les bases de données anthropométriques compatibles au plan international - Partie 2: Protocole d'évaluation de la forme extérieure et de la répétabilité des positions relatives de repères (ISO 20685-2:2023)
Le présent document établit les protocoles d’essai des systèmes d’exploration à l’aide de scanners 3D de surface permettant de collecter des données sur la forme du corps humain et les mesurages. Il ne s’applique pas aux instruments qui mesurent le déplacement de repères individuels.
La majeure partie du présent document concerne les scanners pour le corps entier, mais il s’applique également aux scanners limités à une partie du corps (scanners pour la tête, scanners pour la main, scanners pour le pied). Il s’applique aux scanners corporels qui mesurent le corps humain dans une seule vue. En cas d’évaluation d’un scanner portatif, l’opérateur humain peut contribuer à l’erreur globale. En cas d’évaluation de systèmes dans lesquels le participant subit une rotation, des artéfacts liés au mouvement peuvent être introduits et contribuer aussi à l’erreur globale. Le présent document s’applique aux positions de repères déterminées par un expert en anthropométrie. Il ne s’applique pas aux positions de repères calculées automatiquement par le logiciel à partir du nuage de points.
La qualité de la forme extérieure du corps humain et des positions des repères est influencée par les performances des systèmes d’exploration et des humains, y compris les opérateurs réalisant les mesurages et les participants. Le présent document évalue les performances des systèmes d’exploration en utilisant des objets façonnés plutôt que des participants humains comme objets d’essai.
Les instruments traditionnels doivent être précis au millimètre près. Leur exactitude peut être vérifiée en comparant l’instrument à une échelle étalonnée par rapport à un étalon international de longueur. Pour vérifier ou spécifier l’exactitude des scanners corporels, un objet d’essai étalonné de forme et de dimensions connues est utilisé.
Le présent document s’adresse aux utilisateurs des scanners corporels 3D pour créer des bases de données anthropométriques 3D, aux utilisateurs de ces données ainsi qu’aux concepteurs et fabricants de scanners corporels. Le présent document est destiné à servir de base d’accord sur les performances des scanners corporels entre les utilisateurs des scanners et les fournisseurs de scanners ainsi qu’entre les fournisseurs de bases de données anthropométriques 3D et les utilisateurs de ces données.
Ergonomija - Metode 3D-skeniranja za mednarodno združljive baze antropometrijskih podatkov - 2. del: Protokol ovrednotenja površine telesa in ponovljivosti relativnih merilnih točk (ISO 20685-2:2023)
ISO 20685-2:2015 obravnava protokole za preskušanje sistemov za površinsko 3D-skeniranje v okviru pridobivanja podatkov o obliki človeškega telesa in povezanih meritev. Ne uporablja se za instrumente za merjenje premikanja posameznih merilnih točk.
Čeprav v glavnem obravnava skenerje celotnega telesa, se uporablja tudi za skenerje posameznih delov telesa (skenerje glave, rok in nog). Ta mednarodni standard se uporablja za skenerje telesa, ki merijo človeško telo v enem pogledu. Pri vrednotenju ročnega skenerja je treba upoštevati, da lahko upravljavec vpliva na skupno napako. Pri vrednotenju sistemov, pri katerih se subjekt obrača, je mogoče vpeljati artefakte premikanja, ki lahko ravno tako vplivajo na skupno napako. Ta del standarda ISO 20685 se uporablja za merilne točke, ki jih določi antropometrist. Ne uporablja se za merilne točke, samodejno izračunane s programsko opremo iz točkovnega oblaka.
Na kakovost površinske oblike človeškega telesa in merilnih točk vpliva učinkovitost sistemov skeniranja in vpletenih oseb, vključno z merilci in subjekti. Ta del standarda ISO 20685 obravnava učinkovitost sistemov skeniranja z uporabo artefaktov namesto človeških subjektov kot preskušancev.
Običajni instrumenti morajo biti natančni do milimetra. Njihovo natančnost je mogoče preveriti s primerjavo instrumenta in merila, umerjenega v skladu z mednarodnim standardom za dolžino. Za preverjanje ali določanje natančnosti skenerjev telesa se uporabi umerjen preskušanec z znano obliko in velikostjo.
Ciljno občinstvo so uporabniki 3D-skenerjev telesa za ustvarjanje 3D-antropometričnih zbirk podatkov, vključno s 3D-merilnimi točkami, uporabniki teh podatkov ter načrtovalci in proizvajalci skenerjev. Ta del standarda ISO 20685 je namenjen podajanju osnove za dogovor glede učinkovitosti skenerjev telesa med uporabniki in ponudniki skenerjev ter ponudniki 3D-antropometričnih zbirk podatkov in uporabniki podatkov.
