1 Scope

This part of IEC 62676 specifies the functions, performance, interfaces, environmental adaptability, test methods, performance evaluation and grading rules of real-time intelligent video analysis in surveillance systems.

This document applies to live and forensic, real-time intelligent video analysis devices and systems in video surveillance.

The document is centred on testing performance and grading device functionality which enables:

• Core capability: Classification of objects, detection of specific "object activity", such as "stopping", "starting", "direction of movement", etc.

  Examples are listed in Annex A.

• Complex capability: Detection of "scenarios" which are based on combinations of object activity, such as "loitering", "perimeter intrusion detection", "person down", "tailgating", "intrusion", "abandoned object detection", explosion, fire, flood, potential terrorist attack using a vehicle, owner of an abandoned bag, etc.

  Examples of current scenarios are listed and described in Annex B.

• Degree of difficulty: The application of real operating environments to test the performance under known or required operating stress levels, examples of operating stress levels that are sterile or non-sterile, indoor or outdoor, target obscuration levels, extreme weather conditions, vibrating mechanical rugged environments causing image shake resulting in degradation of image quality requirement, see Table 1 and Annex C.

The purpose of this document is to provide end users, at different levels of the service process, from users and installers, integrators and maintenance companies, to certification providers, with methods to measure the performance of video analysis systems that must also comply with other parts of the standard.
