INTERNATIONAL STANDARD ISO 17215-3:2021

Road vehicles — Video communication interface for cameras (VCIC) —

Part 3: Camera message dictionary

1 Scope

This document specifies the standardized camera messages and data types used by a VCIC camera (OSI layer 7).

Applications hosted on ECUs want to communicate with one or more cameras (e.g. “Ask camera for parameters.”). If the applications can use standardized services supported by the cameras (API layer 7), the development of a vision application is independent on the camera used. The services can be implemented by general libraries.

The definition of streaming data is not an issue of this API.
