Designing safety and security into an embedded vision system

摘要

So far, this series has examined techniques and devices for implementing the functions of an embedded vision (EV) system. This article will describe tools and techniques to ensure the system meets applicable safety and security requirements. A suitable design methodology should include risk assessment to understand the likelihood of technical failure, accident or incorrect operation, and the possible consequences. Medical imaging equipment, industrial vision systems and automotive applications such as the Advanced Driver Assistance System (ADAS) typically require formalised assessment, referencing standards such as ISO 14971 for medical systems. In any case, teams should be able to demonstrate that safety has been given due consideration.
