ISO 10360-13:2021(E)
Introduction
This document is a geometrical product specification (GPS) standard and is to be regarded as a general
GPS standard (see ISO 14638). It influences chain link F of the chain of standards on size, distance,
form, orientation, location and run-out in the general GPS matrix (see Annex H).
The ISO GPS matrix model given in ISO 14638 gives an overview of the ISO GPS system, of which this
document is a part. The fundamental rules of ISO GPS given in ISO 8015 apply to this document and
the default decision rules given in ISO 14253-1 apply to specifications made in accordance with this
document, unless otherwise indicated.
This document has two technical objectives:
1) to test the error of indication when measuring a calibrated test length across the global measuring
volume of the CMS;
2) to test the errors of indication within a locally intended measuring volume.
These two objectives correspond to:
a) the test performed for a probing system and a moving carrier of the probing system in combination
1)
as described in ISO 10360-2, ISO 10360-7, ISO 10360-8, ISO 10360-10, ISO 10360-11 and
ISO 10360-12;
b) the test performed dominantly for the probing system as described in ISO 10360-5, ISO 10360-7,
ISO 10360-8, ISO 10360-9, ISO 10360-10, ISO 10360-11 and ISO 10360-12.
The benefits of these tests are that the measured result has a direct traceability to the unit of length,
the metre, and that it gives information on how the coordinate measuring machine (CMM) or the
coordinate measuring system (CMS) performs in similar length measurements.
An optical 3D CMS as specified by this document is a contactless area measuring sensor delivering
3D data in several individual single views by an optical measuring principle and transforming it into
a common coordinate system. Typical optical measuring principles are pattern projection, fringe
projection and projecting-and-sweeping a scanned line, or similar, delivering single views without
assistance of external information related to position and orientation of the objects to be scanned
relative to the CMS. Typical registration principles are based on a best fitting of commonly captured
position information across at least two different single views by using either or both reference features
attached or surface features of the objects to be scanned.
This document is not intended to apply to other types of CMSs, for example:
— tactile CMMs (Cartesian metrological moving carrier), see ISO 10360-2;
— imaging CMMs (Cartesian metrological moving carrier), see ISO 10360-7;
— CMMs equipped with optical distance sensors (Cartesian metrological moving carrier), see
ISO 10360-8;
— laser trackers, see ISO 10360-10;
— X-ray CTs, see ISO 10360-11;
— articulated arm CMMs, see ISO 10360-12;
— measuring instruments intended to measure surface characteristics, see the ISO 25178 series;
— optical microscopes;
— hand-held laser-line type scanners.
1) Under preparation. Stage at the time of publication: ISO/DIS 10360-11:2021.

ISO 10360-13:2021(E)
Parties can apply this document to the above or other types of CMSs by mutual agreement.
This document specifies:
— performance requirements that can be assigned by the manufacturer or the user of the CMS;
— the manner of execution of the acceptance and reverification tests to demonstrate the stated
requirements;
— rules for verifying conformance;
— applications for which the acceptance and reverification tests can be used.
NOTE 1 Annex E describes possible limitations with regard to less cooperative surface characteristics,
such as colour, glossiness and roughness, and provides a suggested test that can give CMS users an idea of how
representative the maximum permissible error would be when measuring their specific industrial part.
NOTE 2 The optical 3D CMS can be moved and positioned by a manually or automated moving unit. The
position, orientation or both can be used as additional information for the registration.
NOTE 3 The acceptance and reverification tests are designed to mimic real but simple measurements
occurring in practice, subject to the rated operating conditions and the testing procedures. The user is advised
to consider the influence of additional or omitted conditions, procedural steps or both when applying the test
results according to this document to predict the performance of an actual CMS.
For more detailed information of the relation of this document to other standards and the GPS matrix
model, see Annex H.

Geometrical product specifications (GPS) — Acceptance
and reverification tests for coordinate measuring systems
(CMS) —
Part 13:
Optical 3D CMS
1 Scope
This document specifies the acceptance tests for verifying the performance of an optical 3D coordinate
measuring system (CMS) when measuring lengths as stated by the manufacturer. It also specifies the
reverification tests that enable the user to periodically reverify the performance of the optical 3D CMS.
This document is applicable to verification of the measuring performance of CMSs if the surface
characteristics (e.g. glossiness, colour) of the object to be scanned are restricted and within a
cooperative range.
This document does not apply to other types of CMSs, including those covered by the other parts of the
ISO 10360 series.

3.1
optical 3D coordinate measuring system
optical 3D CMS
system performing measurements of spatial coordinates exclusively by optical sensors
ISO 10360-13:2021(E)
3.2
sensor measurement volume
volume of measurement of the sensor realized without movement of the sensor relative to the workpiece
fulfilling the specifications stated by the manufacturer
Note 1 to entry: Dimensional indication of sensor measurement volume stated by the manufacturer can
significantly differ from that which the sensor shows.
3.3
registration
transformation of coordinate systems that brings single-view coordinates into a unified coordinate
system
Note 1 to entry: A transformation is realized for example by a rigid transformation, consisting of either
translation, rotation or both.
Note 2 to entry: Each single view holds its own coordinate system and requires a transformation to the unified
coordinate system.
Note 3 to entry: The registration is invertible. The inverse registration can be performed by applying the inverse
transformation.
Note 4 to entry: In practice, the transformation parameters are derived first, then the transformations occur
either immediately or at a later stage.
Note 5 to entry: A registration can require a person to operate the CMS.
3.4
fusion
operation that merges two or more sets of measured coordinates into a unified set of measured
coordinates
Note 1 to entry: Fusions are performed to improve the measurement, e.g. to reduce the dispersion and the
mismatch of single views.
Note 2 to entry: Fusions are typically irreversible (not invertible).
Note 3 to entry: A fusion can include any number of elementary operations in combination or in sequence, such as
coordinate transformation, averaging, outlier rejection, decimation, convolution and filtration.
Note 4 to entry: The fusion can occur either immediately or at a later stage.
3.5
concatenated measurement volume
volume of measurement of the CMS obtained by movement of the sensor relative to the workpiece and
the registration fulfilling the specifications stated by the manufacturer
Note 1 to entry: The concatenated measurement volume can be determined by design of a measuring cabin
typically having a cuboid boundary or a three-dimensional size of the intended workpiece.
Note 2 to entry: A concatenated measurement volume can have either a significantly larger volume than the
sensor measurement volume or a similar volume to the sensor measurement volume.
3.6
single-view measurement
measurement of spatial coordinates done with an optical sensor without movement relative to the
workpiece
Note 1 to entry: Single-view measurement is performed with no movement of the carrier, registration or fusion.
Note 2 to entry: Single-view measurement can include repeated measurements, for example multiple exposures,
provided that no movement of the optical sensor relative to the workpiece occurs from the first exposure to the
last.

Note 2 to entry: Both percentiles, 95 % and All, are of the measured points according to the rated operating
conditions. When these conditions include pre-processing such as prefiltering or meshing, then the percentiles
apply to such points after this application.
Note 3 to entry: 5 % of the measured points in the “All” data set is eliminated to determine P .
Form.Sph.D95%:j:O3D
Outliers can be eliminated by this operation.
Note 4 to entry: It can be beneficial to evaluate probing errors from point cloud both from “95 %” population and
“All” population. A difference in these two test results can reveal influences of smoothing filters or equivalent
functions potentially pre-installed as an integral part of the CMS or the associated software, which is not always
transparently visible for users of the CMS.

Note 2 to entry: Both percentiles, 95 % and All, are of the measured points according to the rated operating
conditions. When these conditions include pre-processing such as prefiltering or meshing, then the percentiles
apply to such points after this application.
Note 3 to entry: The probing size error is determined by the errors of the sensors (caused by, for example, noise,
digitization, image distortion, optical interaction with the surface of the material standard, calibration, faulty
algorithms) and of the positioning system.

5 Rated operating conditions
5.1 Environmental conditions
Limits for permissible environmental conditions (e.g. temperature conditions, air humidity, vibration
and ambient lighting at the site of installation that influences the measurements) shall be specified by:
— the manufacturer, in the case of acceptance tests;
— the user, in the case of reverification tests.
In both cases, the user is free to choose the environmental conditions under which the testing is
performed within the manufacturer’s specified limits given in the CMS data sheet.
The user is responsible for providing the environment enclosing the CMS as specified by the
manufacturer in the data sheet. If the environment does not meet the specifications, then the maximum
permissible errors cannot be required to be verified.

5.2 Operating conditions
5.2.1 General
For all the tests described in this document, the optical 3D CMS shall be operated according to the rated
operating conditions and the default settings stated by the manufacturer.
If any of the conditions and settings are not specified, the user is free to choose.
The manufacturer may specify extra specifications for special operating conditions and settings at its
discretion.
Specific areas in the manufacturer’s manual to be adhered to include:
1) machine start-up or warm-up cycles;
2) qualification of the CMS;
3) achievement of thermal stability of the CMS;
4) location, type, number of thermal sensors when these are at least partially applicable;
5) software filters;
6) surface characteristics of the material standards such as colour, roughness, glossiness, light
scattering characteristics;
7) default procedures and settings for data registration and data fusion;
8) pre-installed smoothing function;
9) concatenated measurement volume if applicable.
NOTE The CMS qualification can include a number of adjustments and parameter settings, such as those
related to the geometry in a sub-system assembly, the illumination, the optical sensing and the numerical
filtration.
5.2.2 Material and surface characteristic of material standards
The material used for the material standards shall be stated by the manufacturer. Different materials
have different optical characteristics such as reflection factor, optical penetration depth (volume
scattering), colour or scattering characteristics, which can influence the test values. The roughness of
the material standard shall be negligibly small compared to the maximum permissible error.
Material, surface characteristics and colour of the material standards shall be described in the technical
documentation of the instrument that is available to the (potential) user. If the manufacturer fails to
specify the material, the surface characteristics of the material standard, or both, then the user is free
to choose.
If a specific surface preparation, such as usage of powder spraying or similar, is explicitly stated in the
technical data sheet, the surface preparation shall be used in the tests.
NOTE 1 Material standards can be made of diverse materials, such as ceramics or steel.
NOTE 2 Assessment of optical characteristics of the surface to be measured is described in Annex E.
Reference standards used for system qualification shall not be used for the tests described in this
document.
The length of each material standard shall be calibrated and the calibration uncertainty shall be taken
into account according to ISO 14253-1, when verifying conformity by acceptance or reverification tests.

5.2.3 Pre-processing
Pre-processing of raw measurement data as a part of the rated operating conditions shall be indicated
in the technical documentation of the instrument that is available to the (potential) user.
NOTE Pre-processing is typically implemented to realize ou
