IEC 63033-3:2022

Overview

IEC 63033-3:2022 - Multimedia systems and equipment for vehicles - Surround view system - Part 3: Measurement methods - specifies standardized measurement methods for vehicle surround view systems used for drive monitoring. This second edition (2022) replaces the 2019 edition and aligns the IEC 63033 series scope with current vehicle surround view and driver-monitoring use cases. The standard defines how to measure camera/image quality, calibration, field of view (FOV) coverage and time behaviour parameters (start‑up, frame rate, latency) for composite and single-camera views.

Key technical topics and requirements

• Scope & model: Measurement methods apply to surround view systems that generate composite images and single-camera images from externally mounted cameras.
• Camera image quality: Cameras must meet image‑quality requirements referenced to ISO 16505:2019 (image quality clauses and measurement procedures).
• Camera resolution: Minimum camera resolution specified as 300 000 pixels or more.
• Camera calibration & verification: Calibration per IEC TS 63033‑1 (Annex C). Verification includes capturing an orthogonal reference frame drawn 1.5 m from the vehicle outline; composite guidance lines must match within 10 cm tolerance.
• Field of view (FOV): Defines visible area requirements for composite or converted single‑camera displays. Where intended to replace type‑approved indirect vision systems, FOVs shall follow UN Regulations (e.g., UN R46 and UN R125, Classes I–VI). Annex A provides illustrative FOV examples.
• Time behaviour:
  • Start‑up time: Manufacturer must report start‑up; measured from ignition to initial composite view. Requirement: ≤ 7 s (measured per ISO 16505:2019).
  • Frame rate: Manufacturer must report frame rate. The standard references a nominal frame rate (typical operation) and allows drops during low‑speed manoeuvres - frame rate shall not fall below 15 fps; the document also cites nominal target values (see ISO 16505 references for measurement).
  • Latency: End‑to‑end latency (capture to display) < 200 ms, measured per ISO 16505:2019 procedures.

Practical applications and who uses this standard

IEC 63033-3:2022 is essential for:

• Automotive OEMs and Tier‑1 suppliers designing and integrating surround view / drive‑monitoring systems.
• ADAS engineers and system integrators validating camera networks, stitching/composite algorithms and human‑machine interfaces (HMIs).
• Test laboratories and certification bodies performing conformance testing, verification, and supplier audits.
• Regulatory and compliance teams ensuring systems align with UN Regulations and ISO test procedures where surround view functions may substitute type‑approved mirrors or cameras.

Implementing IEC 63033-3 helps assure reliable FOV coverage, consistent image quality, predictable latency and safe start‑up behaviour for surround view systems.
