IEC 63033-1:2022

Overview

IEC 63033-1:2022 is an international standard developed by the International Electrotechnical Commission (IEC) focusing on multimedia systems and equipment for vehicles, specifically the surround view system. This Part 1: General edition establishes the foundational model for generating the surrounding visual image in automotive surround view systems. As a technical revision, it cancels and replaces the previous IEC TS 63033-1 from 2017, providing updated guidance and specifications essential for the standardization and implementation of surround view technology in vehicles.

The standard covers general aspects, including system models, camera configurations, rendering processes, and visualization techniques necessary to produce accurate 3D surround imagery for driver assistance. The document aims to promote international uniformity and facilitate development and interoperability in vehicle surround view systems.

Key Topics

• System Model for Surround View
  IEC 63033-1 defines a comprehensive system model incorporating the number of cameras, their fields of view, and the method for projecting captured images onto a 3D projection surface. This ensures consistent and realistic reproduction of the vehicle's surroundings.

• Camera Configuration and Calibration
  The standard specifies camera parameters such as lens distortion data-both rotationally symmetric and non-rotationally symmetric lenses-as well as optical axis shifts. Detailed calibration procedures are outlined to ensure precise image capture and projection accuracy.

• 3D Projection and Visualization
  Guidance on projecting visual images onto a 3D virtual surface is provided, including free eye point visualization capabilities that allow multiple viewing angles. This enhances the driver's spatial awareness and situational understanding.

• Rendering and Composite View Data
  IEC 63033-1 details how to handle composite view data, including 3D surface definitions, capture sizes, eye point parameter conversion, and integration of a virtual 3D car model. It also covers layout and layer settings for final image rendering.

• Data Formats and Specifications
  The document defines specific data formats for camera calibration, distortion correction, optical shifts, and rendering inputs to promote uniform implementation across manufacturers and suppliers.

Applications

• Advanced Driver Assistance Systems (ADAS)
  Surround view systems are a key component of ADAS, providing drivers with panoramic views around the vehicle to aid parking, lane changing, and maneuvering in tight spaces.

• Vehicle Safety Enhancements
  By accurately visualizing blind spots and obstacles, this standard supports the development of safety-critical features, reducing accident risks caused by limited visibility.

• Automotive Multimedia Integration
  The standard supports integration of surround view visualization into in-vehicle multimedia displays, improving user experience and interface consistency.

• Automotive Camera System Development
  Manufacturers use IEC 63033-1 to design and calibrate vehicle camera arrays and image processing algorithms that meet international requirements.

• Testing and Certification
  This standard provides a benchmark for evaluating the functionality, accuracy, and performance of surround view systems during development and certification processes.
