Bio-Queue – Deeper Insights

The main tasks associated with image processing are performed on the server, with the potential to distribute these tasks across several servers, depending on requirements.

‍Reception
Image templates are received with minimal lag, with initial processing already having been carried out locally following capture.

‍Recording
Templates are recorded in a SQL Server database with a unique identification code that contains data on capture camera, location and timestamp. The template and, if present, the face image from which the template was generated, can be saved to binary storage for later retrieval.

‍Searching
Each template recorded will be used as a probe image to be searched against the current cache of face templates. If there is a match, this will be recorded in the database to provide data for queue measurement statistics.

‍Caching
Following the search process, templates are added to the current cache so that subsequent captures of an individual can be matched to previous images from earlier in their journey through the airport.

‍Statistics
Data from matches and timestamps is used to calculate and record progression of passengers. This module can be configured to allow for measurements to be provided on an individual or aggregated basis as required.

The user interface provides clients with access to system settings, enabling cameras and their locations to be registered, and entry points, waypoints and exits to be defined. It also provides the means to configure alerts, dashboards and reports, which can be integrated with the airport’s passenger management service.
