Secure olympics games with technology: Intelligent border surveillance for the 2022 Beijing winter olympics

Building a border surveillance system with integrated surveillance technologies is a crucial security strategy for Olympic venues. Although the previous Olympic Games have a long history of using surveillance technologies, there are perennial challenges in terms of false alarms, energy consumption, and labor and capital costs. In this paper, an IoT-based multi-agent intelligent border surveillance method with less cost is proposed. Following a two-level autonomous mechanism, the method assures agent-level self-patrolling by distributed nodes and system-level multi-agent surveillance task coordination by the central server. The core entity of each distributed node is the IoT-based SmartGM, an autonomous surveillance tower integrating multi-modal surveillance devices. Finally, based on intelligent visual reasoning algorithms, the proposed activation strategy updates surveillance devices’ activation status simultaneously according to global states, ensuring long-term operation. This method has been successfully applied in the ski venue of the 2022 Beijing Winter Olympics.
