Information technology — Computer graphics, image processing and environmental data representation — Style representation for mixed and augmented reality

This document specifies: 1) Constructs for representing and specifying various augmentation and presentation styles. While augmentations can be in modalities other than the visual (e.g. aural, haptic), this work addresses the visual augmentation style only. 2) A model for how to associate the stylization constructs to the augmentation objects. Specifically, the MAR behavior object in ISO/IEC 3721 is extended for this purpose. 3) Other miscellaneous functionalities and abstractions that support the stylization of augmentation objects.

Information technology — Computer graphics, image processing and environmental data representation — Mixed and augmented reality (MAR) reference model

This document defines the scope and key concepts of mixed and augmented reality, the relevant terms and their definitions and a generalized system architecture that together serve as a reference model for mixed and augmented reality (MAR) applications, components, systems, services and specifications. This architectural reference model establishes the set of required sub-modules and their minimum functions, the associated information content and the information models to be provided and/or supported by a compliant MAR system. The reference model is intended for use by current and future developers of MAR applications, components, systems, services or specifications to describe, compare, contrast and communicate their architectural design and implementation. The MAR reference model is designed to apply to MAR systems independent of specific algorithms, implementation methods, computational platforms, display systems and sensors or devices used. This document does not specify how a particular MAR application, component, system, service or specification is designed, developed or implemented. It does not specify the bindings of those designs and concepts to programming languages or the encoding of MAR information through any coding technique or interchange format. This document contains a list of representative system classes and use cases with respect to the reference model.

This document identifies the reference framework for the benchmarking of vision-based spatial registration and tracking (vSRT) methods for mixed and augmented reality (MAR). The framework provides typical benchmarking processes, benchmark indicators and trial set elements that are necessary to successfully identify, define, design, select and apply benchmarking of vSRT methods for MAR. It also provides definitions for terms on benchmarking of vSRT methods for MAR. In addition, this document provides a conformance checklist as a tool to clarify how each benchmarking activity conforms to this document in a compact form by declaring which benchmarking processes and benchmark indicators are included and what types of trial sets are used in each benchmarking activity.

ISO/IEC 18025:2014(Main)

Information technology — Environmental Data Coding Specification (EDCS)

ISO/IEC 18025:2014 provides mechanisms to specify unambiguously objects used to model environmental concepts. To accomplish this, a collection of nine EDCS dictionaries of environmental concepts are specified: classifications: specify the type of environmental objects; attributes: specify the state of environmental objects; attribute value characteristics: specify information concerning the values of attributes; attribute enumerants: specify the allowable values for the state of an enumerated attribute; units: specify quantitative measures of the state of some environmental objects; unit scales: allow a wide range of numerical values to be stated; unit equivalence classes: specify sets of units that are mutually comparable; organizational schemas: useful for locating classifications and attributes sharing a common context; and groups: into which concepts sharing a common context are collected. A functional interface is also specified. As denoting and encoding a concept requires a standard way of identifying the concept, ISO/IEC 18025:2014 specifies labels and codes in the dictionaries. ISO/IEC 18025:2014 specifies environmental phenomena in categories that include, but are not limited to, the following: abstract concepts (e.g., absolute latitude accuracy, geodetic azimuth); airborne particulates and aerosols (e.g., cloud, dust, fog, snow); animals (e.g., civilian, fish, human, whale pod); atmosphere and atmospheric conditions (e.g., air temperature, humidity, rain rate, sensible and latent heat, wind speed and direction); bathymetric physiography (e.g., bar, channel, continental shelf, guyot, reef, seamount, waterbody floor region); electromagnetic and acoustic phenomena (e.g., acoustic noise, frequency, polarization, sound speed profile, surface reflectivity); equipment (e.g., aircraft, spacecraft, tent, train, vessel); extraterrestrial phenomena (e.g., asteroid, comet, planet); hydrology (e.g., lake, rapids, river, swamp); ice (e.g., iceberg, ice field, ice peak, ice shelf, glacier); man-made structures and their interiors (e.g., bridge, building, hallway, road, room, tower); ocean and littoral surface phenomena (e.g., beach profile, current, surf, tide, wave); ocean floor (e.g., coral, rock, sand); oceanographic conditions (e.g., luminescence, salinity, specific gravity, turbidity, water current speed); physiography (e.g., cliff, gorge, island, mountain, reef, strait, valley region); space (e.g., charged particle species, ionospheric scintillation, magnetic field, particle density, solar flares); surface materials (e.g., concrete, metal, paint, soil); and vegetation (e.g., crop land, forest, grass land, kelp bed, tree).

ISO/IEC 19775-1:2013(Main)

Information technology — Computer graphics, image processing and environmental data representation — Extensible 3D (X3D) — Part 1: Architecture and base components

ISO/IEC 19775, X3D, defines a software system that integrates network-enabled 3D graphics and multimedia. Conceptually, each X3D application is a 3D time-based space that contains graphic and aural objects that can be dynamically modified through a variety of mechanisms. ISO/IEC 19775-1:2013 defines the architecture and base components of X3D. The semantics of X3D describe an abstract functional behaviour of time-based, interactive 3D, multimedia information. ISO/IEC 19775-1:2013 does not define physical devices or any other implementation-dependent concepts (e.g. screen resolution and input devices). It is intended for a wide variety of devices and applications, and provides wide latitude in interpretation and implementation of the functionality. For example, it does not assume the existence of a mouse or 2D display device. Each X3D application: implicitly establishes a world coordinate space for all objects defined, as well as all objects included by the application; explicitly defines and composes a set of 3D and multimedia objects; can specify hyperlinks to other files and applications; can define programmatic or data-driven object behaviours; can connect to external modules or applications via programming and scripting languages; explicitly declares its functional requirements by specifying a profile; can declare additional functional requirements by specifying components.
