CIE TC 2-62

PTB

The outputs of this project, especially regarding luminance measurements of HDR contrasts as present in typical Near-Field Goniophotometer measurements, will be disseminated to TC2-62 by PTB as a member of the TC. The TC meets in regular basis (i.e., at least twice a year). Feedback on the presented results will be sought.

CIE TC 2-86

EPFL, METAS, PTB

The outputs of the project, especially regarding glare evaluation using HDR imaging, will be disseminated to TC 2-86 by EPFL who chairs the TC, and METAS and PTB as members of the TC. The TC meets in regular basis (i.e., at least 3 meetings per year). Feedback on the presented results will be sought.

CIE 237:2020 “Non-Linearity of Optical Detector Systems” describes the characteristic of an CCD-based but already outdated ILMD, namely having a rather low ADC-resolution and thus low dynamic range. Also, the CIE 244:2021 “Characterisation of Imaging Luminance Measurement Devices” lacks aspects of the above mentioned HDR mode for imaging systems realised by post-processing of image sequences.

For the measurements according to the new CIE recommendations CIE 232:2019 “Discomfort Caused by Glare from Luminaires with a Non-Uniform Source Luminance” and CIE 243:2021 “Discomfort Glare in Road Lighting and Vehicle Lighting” just published, a high spatial resolution and a high dynamic range is required, which could only be provided by HDR imaging.

The work and results of this project are relevant to these technical reports, which are being looked at by CIE TC 2-86, CIE TC 2-95 and CIE TC 2-96

CIE TC 2-95

METAS, PTB

The outputs of the project, especially regarding obtrusive light evaluation using HDR imaging, will be disseminated to TC2-95 by METAS who chairs the TC, and PTB as a member of the TC. The TC meets in regular basis (i.e., at least 3 meetings per year). Feedback on the presented results will be sought.

CIE TC 2-96

PTB, CSIC, METAS

TC2-96 deals with the revision of ISO/CIE 19476, the standard for characterising illuminance and luminance meters. The output of the project, especially the generic model to evaluate HDR images, will be used to pave the way to standardise HDR procedures for luminance measuring devices. The outputs of this project will be disseminated by PTB who chairs the TC, and CSIC and METAS members of the TC. The TC meets in regular basis (i.e., at least 2 meetings per year). Feedback on the presented results will be sought.

CIE TC 3-57

EPFL, TUB

The outputs of the project, especially regarding glare evaluation using HDR imaging, will be disseminated to TC3-57 by EPFL and TUB. The TC meets twice a year. Feedback on the presented results will be sought.  

CIE TC 4-xx

TUB

TUB will share the outputs of the project with this new TC, which will be established to continue the work of TC 4.33 (Discomfort glare), and focus on specific recommendation for models depending of application and measurement of all relevant photometric data based on CIE 243:2021 (chaired by TUB). The TC meets twice a year.  Feedback on the presented results will be sought.

CIE TC 4-50

TUB

TUB will share the outputs of the project with this TC, which is responsible for the measurement and characterisation of road reflexion and road marking with HDR; for wet roads high luminance (high contrast) are produced by headlamps; and has a need of description for in-situ measurements. The TC meets twice a year.  Feedback on the presented results will be sought.

CIE TC 4-58

METAS

Project outputs related to measurement of colourful outdoor scenes using HDR imaging will be disseminated to TC4-58 by METAS. The TC meets in regular basis (i.e., at least 3 meetings per year). Feedback on the presented results will be sought.

CIE TC 8-18

CSIC

CSIC is member of CIE TC8-18. CSIC will brief the committee members on the developments of the project, The TC meets in regular basis (i.e., at least twice a year).  Feedback on the presented results will be sought.

CIE JTC 12

CSIC (chair), CMI, CNAM, METAS, PTB

The outputs of this project, especially regarding HDR algorithms and traceability, will be communicated to this committees by CSIC. The TC meets in regular basis (i.e., at least twice a year).  Feedback on the presented results will be sought.

CEN TC-169 – WG11

EPFL

CEN TC 169 WG 11 will meet regularly during the project lifetime to revise the EN17037 and EPFL will share the outputs of the project, in particular the glare evaluation using HDR imaging, with this working group.  Feedback on the presented results will be sought.

The European standard EN 17037:2019 [2] (on daylight) proposes the use of an HDR imaging measurement system using a fish-eye lens for verifying the daylight glare probability (DGP) for site measurements. This project addresses these types of devices and the uncertainty propagation for glare evaluation, accounting for geometrical effects due to the fish-eye lens of the camera.

CEN TC-169 – WG7

METAS, PTB

CEN TC 169 WG7 meets more than once a year either face to face or by WebEx. METAS as current representatives in CEN TC 169 WG7 will forward information from CIE and this project to CEN and seek for their feedback.

PTB is reports and contributes to CEN TC 169 via the German national standardisation body DIN by being a member of the advisory board of DIN and by memberships in the technical committee DIN FNL-3.

DIN FNL

PTB

The progress and results of the JRP will be reported in the German national standardisation body DIN by PTB being a member of the advisory board of DIN and by the membership of PTB (co-chair) in the technical committee DIN FNL-3 “Photometry”.  The TC meets at least twice a year.  Feedback on the presented results will be sought.

The European standard EN 13201:2015 [3] (road lighting) allows the use of ILMDs for the determination of disability glare based on the threshold increment f_TI. This project will have a significant impact on the use of this method and increase the confidence of the users.

Specific fields are addressed in different national standards and guidelines (cf. for Germany LiTG TR10, TR12.3, TR40; but also LAI (Guide for light emission).
