Two tech companies operating under Hong Kong’s Smart Government Innovation Lab have rolled out solutions that are now ready to be acquired by companies and institutions.
Solution I – Heritage Conservation Platform
Solution description
The company under the Lab has proposed a comprehensive solution for heritage conservation that encompasses data capture, 3D modelling, and online visualisation of realistically rendered models. It supports a variety of capturing sensors and raw data types, including camera images, LiDAR point clouds, and RGB-D data, and can be used with stationary, handheld, robotic, or UAV platforms. With high-precision modelling, realistic texturing and rendering, and a lightweight web-based visualisation platform, this solution is ideal for archiving, exhibiting, renovating, and educational purposes.
Application Areas
The solution was designed to be applied in the areas of City Management, Education, Infrastructure, Recreation and Culture as well as Tourism.
Technologies Used
The solution employs the latest in Artificial Intelligence (AI), Augmented Reality, Cloud Computing, Data Analytics, Deep Learning, Mixed Reality as well as Virtual Reality.
Use case
In Hong Kong, there are 132 declared monuments and over 1000 historic buildings with significant heritage value. To safeguard and preserve this archaeological and architectural heritage, a comprehensive 3D surveying record is essential for future preservation and monitoring against potential damage or destruction.
Currently, LiDAR scanning and image records are widely used for digital preservation, but the disorganized data and large size make them difficult to use and constructing 3D models from raw scanning data is time-consuming and labour-intensive.
The company has developed a cutting-edge AI-assisted algorithm that can accurately convert raw captured data into 3D models at a cost-effective price. The structured 3D models have the advantage of low data volume, ease of access, and meaningful information for engineers. The solution offered is modular and covers the entire process from data collection to 3D model generation and online visualization, offering great flexibility.
To raise public awareness, promote participation, and enhance cultural tourism, the company provides a realistically rendered 3D model and a lightweight, web-browser-based visualization that can be accessed from anywhere and on any device.
Solution II – LifeOnline: Smart Personal Emergency System for Law Enforcement
Solution description
Law enforcement officers face various dangers on a regular basis. LifeOnline is a tool that keeps officers, especially those working alone in remote areas, connected with their team. In emergency situations, officers can seek help from their supervisor by pressing an SOS button on their smartphone. If they encounter danger, such as falling from a height or a medical emergency, the smartwatch will notify their team.
Using long-range wireless communication technology, LoraWAN, officers can stay connected even in remote areas covered by the government’s GWIN IOT network. If necessary, portable LoraWAN gateways and concentrators can further extend network coverage. The compact size of the smartwatch allows it to be used as standard equipment for law enforcement officers in their daily operations.
Application Areas
The solution was designed to be applied across the areas of Health as well as Law and Security.
Technologies Used
The solution employs the latest in Cloud Computing, the Internet of Things (IoT) as well as Mobile Technologies.
Use case
The officers are connected with their teams and could get help in dangerous and emergency situations.
