With the continuous advancement of urbanization, urban development has gradually revealed many problems. At the end of 2012, China’s Ministry of Housing and Urban-Rural Development initiated the concept of a “harmonious, green and smart city”. Smart cities involve almost all urban component systems such as planning, municipal construction, transportation facilities, public services, dynamic monitoring, government decision-making, people's livelihood, and environmental protection. When combined, this poses new challenges to information acquisition and integration.
The key to information acquisition and integration is an accurate and detailed 3D skeleton, a product that mobile LiDAR readily produces. Mobile Lidar can quickly, accurately and efficiently obtain the necessary geometric city data to facilitate the development and implementation of various smart city initiatives.
