Video-based Vehicle Surrounding Awareness for Air Cargo Transit Security under All-Weather Conditions


The International Civil Aviation Organisation has required all outgoing air cargoes to go through security screening before loading onto the aircrafts since July 1, 2021. In view of such increase in security screening demand, the Civil Aviation Department (CAD) has recognised over 130 Regulated Air Cargo Screening Facilities (RACSFs) to conduct air cargo security screening at off-airport locations. Once the air cargoes are screened at the RACSFs, they are required to be securely transported to the cargo terminal operators (CTOs) at the Airport.

To help the industry enhance the efficiency and cost-effectiveness of the operation, LSCM has developed a video-based intrusion monitoring and management system to enable open-top flatbed trailers to provide secure transportation of the air cargoes from the RACSFs to the CTOs. The system consists of 3 core components developed for open-top flatbed trailers. The first component is a set of camera modules installed in the open-top flatbed trailer to provide full visual coverage of all open sides of the flatbed area. The second component is a video analytics intrusion detection module using deep learning methods for performing onboard intrusion detection. The third component is a management console module to let the truck driver manage the monitoring process during the transportation and to communicate with the online intrusion monitoring service about the truck location and any detected intrusion incidents.

This system helps track the time and location of any intrusion incidents happened during the air cargo transit between a secured off-airport screening facility and a CTO at the Airport. To the airfreight industry, it serves as a capital investment-based security monitoring method over all air cargo pallets on a truck, an alternative to the existing consumable-based protective net methods individually applied over each air cargo pallet on a truck.

SmartAP: Wi-Fi Positioning and Optimisation for a Smart City

Population ageing has become a global issue and Hong Kong is also facing the same challenge.  Hospitals, elderly care centres and caregivers are in need of technology to cope with the wandering problem of the patients with dementia.

imgLSCM collaborated with The Hong Kong University of Science and Technology to deploy the SmartAP for locating patients and asset tracking in Tseung Kwan O Hospital. Wireless mesh network is used to extend the sensor connectivity in the hospital. SmartAP helps to locate, track and geo-fence the patients with dementia, as well as locate the medical assets which are shared and often randomly placed in the premises. It can also track the bed vacancy in the ward. SmartAP IoT sensors are installed in major areas such as lift lobbies, exits, and entrances in the hospital. These sensors are connected to the network, using mesh technology at the blind spots. The patients with dementia only need to wear an RF (BLE) tag, which can be tracked by the surrounding SmartAP IoT devices. With the SmartAP technology and RF tags, patients’ location inside the hospital can be easily found. Alarm will be triggered to alert the doctors, nurses and security guards if the patients with dementia wander away.

The technology can be deployed in similar premises such as elderly centres to enhance the effectiveness and efficiency of the services and alleviate the workload of the caregivers.
