BS ISO 17215-3:2021

What is ISO 17215-3 about? 

ISO 17215-3 is the third part of multiple series that 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 of the camera used. The services can be implemented by general libraries. 

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

NOTE- 

ISO 17215-3 is related to the general information and use case definition. This is a general overview document which is not related to the OSI model. 

Who is ISO 17215-3 for?  

ISO 17215-3 on video communication interface for cameras is useful for: 

• Manufacturer and supplier of VCIC 
• Vehicle owner/driver 
• Installer of VCIC 
• Automotive industry 
• Technician of the vehicle 
• Vehicle regulatory authority 
• Vehicle repair shop 

Why should you use ISO 17215-3?  

Driver assistance systems are increasingly common in road vehicles.  Analogue cameras were used in the beginning because of the lower complexity of the first systems. With the increasing demand for more advanced functionality, digital image processing has been introduced. One box design camera (combining a digital image sensor and a processing unit) is being used in vehicles as well. 

Currently, the market demands such systems with multiple functions. Even different viewing directions are in use. It seems plausible that in the near future a single vehicle could have between 6 and 12 cameras. For this reason and others like limitations in size, power consumption, etc., designs have been made where the cameras are separated from the processing unit. Therefore, a high-performance digital interface between camera and processing unit is necessary. 

The video communication interface for cameras as specified in ISO 17215-3 will be helpful in following ways: 

• To incorporate the needs of the whole life cycle of an automotive grade digital camera 
• Utilizes existing standards to define a long-term stable state-of-the-art video communication interface for cameras, usable for operating and diagnosis purposes, 
• Can be easily adapted to new physical data link layers including wired and wireless connections by using existing adaption layers, and 
• Is compatible with AUTOSAR 

ISO 17215-3 has been established in order to define the use cases, the communication protocol, and the physical layer requirements of a video communication interface for cameras, which covers the needs of your assistance applications. 

ISO 17215-3 is related to the general information and use case definition of the VCIC camera. It covers the application layer implementation of the video communication interface for cameras including the API. 

What’s changed since the last update? 

BS ISO 17215-3:2021 supersedes BS ISO 172153:2014, which is withdrawn 

This second edition cancels and replaces the first edition (ISO 172153:2014), which has been technically revised. 

The main changes compared to the previous edition are as follows: 

• Corrections of Formulae and scaling in 7.6.8 
• Editorial adoptions and corrections
