1. Project context

With the rapid pace of global urbanisation, traditional urban management methods face increasing challenges. As an international metropolis, Hong Kong’s complex urban management needs and urgent demand for innovative technologies are especially prominent. Therefore, Hong Kong is committed to embracing the smart city concept to enhance operational efficiency, improve the quality of life for its residents, and strengthen its capacity for sustainable development.

In this fast-evolving digital era, GVI is committed to integrating cutting-edge technologies to advance smart city development. Our flagship product, LiMobile M1, supports the Hong Kong Productivity Council (HKPC) in exploring smart city solutions, representing not only technological innovation but also a leap in refined management and digital services for Hong Kong.

The core of a smart city lies in accurate data collection and efficient utilisation. The LiMobile M1, with its excellent 3D modelling capabilities, high-precision image acquisition, and processing performance, delivers professional solutions for 3D map construction, road asset management, 3D scene simulation, and other key areas.

2. Solution

5. Application of the Hong Kong Productivity Council

The Hong Kong Productivity Council has applied LiMobile M1 technology in several areas, aiming to promote the development of smart cities in Hong Kong:

(1) High-definition map construction and 3D scene construction

LiMobile M1 HD(high definition) map-building tasks in streets and key areas in Hong Kong to generate high-resolution city maps. These maps show detailed key information about road networks, traffic signs, road conditions and so on, providing important data support for traffic management departments.

LiMobile M1 can build a detailed 3D city model. These three-dimensional scenarios not only provide urban planners with powerful tools for urban planning and design but also can simulate various urban environments and emergencies, thus enhancing the predictability and response-ability of urban management.

(2) City asset identification and the promotion of smart cities

With AI-based Road Marking and Facility Extraction. Complete AI pipeline for point cloud and image data from annotation, training to inference. LiMobile M1 can accurately identify and locate a variety of assets in urban roads, covering streetlights, traffic lights, road markings, and various road facilities. This function provides the city management department in Hong Kong with intelligent asset management, thus optimizing the efficiency of maintenance operations.

Hong Kong has adopted the LiMobile M1 technology and promoted the multi-dimensional progress of smart city construction. By AI-based Point Cloud Intelligent Classification (Built-in pre-trained models for various scenarios).

Asset management improvement: through automatic detection technology and data analysis, it can update road assets in real-time, improve the efficiency of maintenance work and extend the service life of assets.

Emergency response is optimized: the 3D model can be used to simulate natural disasters and emergencies and formulate emergency plans in advance to enhance the resilience of the city.

(3) Urban planning and design

3D Visualization Aided Planning: Through 3D modelling, city managers can intuitively simulate future urban development and road expansion plans, assisting in making better-informed planning decisions. For example, when planning new roadways or bridges, 3D modelling can simulate the interaction of these facilities with the existing urban infrastructure, avoiding irrational designs.

Enhancing Urban Adaptability and Resilience: In the face of natural disasters, traffic congestion, and other emergencies, smart city systems can leverage 3D modelling and data from asset surveys to perform simulations and analyses, making rapid response decisions to improve the city’s capability to cope.
