This project belongs to the field of ldquo; information technology rdquo; and involves multi-disciplinary fields such as surveying and mapping, electronic information, navigation, and remote sensing. Geospatial information is an important part of spatial information infrastructure. The cross-domain information integration, technology integration, and industrial integration formed by ldquo; geographical information +rdquo; has penetrated into all levels of social development. Full space, full element, and full three-dimensional data collection is the basis to meet the needs of ubiquitous geographical information. Mobile measurement is a fast and effective data collection technical means. Due to the limitations of low altitude, surface, underground and complex urban spaces, drones are needed to be used., vehicle-mounted, backpack and other mobile measurement methods can work together to achieve seamless and complete data collection. Lidar is the core component of mobile measurement. ldquo; Performance-Efficiency-Cost rdquo; has always restricted the popularization of mobile measurement technology. In particular, each mobile measurement platform such as drones, vehicle-mounted vehicles, and backpacks uses a specific type of Lidar, which further exacerbates the contradiction between the extensive demand for mobile measurement and ldquo; Performance-Efficiency-Cost rdquo; Developing a multi-platform Lidar with one machine for multiple purposes rdquo;is an effective way to solve the bottleneck of industrialization of this technology. Universality, miniaturization, high precision and high efficiency are the main problems in breaking through multi-platform Lidar technology. Achieving power measurement accuracy by mobile measurement is another problem faced by multi-platform lidar space information acquisition systems. Relying on the support of the National Natural Science Foundation of China, 863, and major strategic emerging industry projects in Shanghai City, this project has broken through the design and manufacturing of multi-platform lidar, and the research and development of multi-platform lidar spatial information acquisition system, multi-platform lidar data joint processing technology and its industrialization technology. The main technological innovations include: (1) Adopt an optical, mechanical and electrical integration structural design such as integrated control of an embedded real-time operating system, rapid clamping and positioning structure, and a modular expandable structure supporting multi-sensor integration, which breaks through the key technologies of multi-platform lidar design and manufacturing and meets the requirements of versatility, miniaturization, high precision, and high efficiency. It realizes rapid switching without calibration across platforms such as airborne, vehicle-mounted, shipborne and backpack, and develops a spectral spatial information acquisition system with better performance than similar foreign products. (2) Breakthrough the technical problems of high-precision control and processing of mobile measurement point clouds, and solve the problems of high trajectory accuracy and low target positioning accuracy of mobile measurement systems. (3) Breakthrough in key technologies for the management, processing and release of massive point clouds and panoramic images, effectively solving the problem of efficient and automated processing of massive data in mobile measurement. (4) Propose a new multi-industry design and production model supported by point cloud, design and establish a mobile measurement engineering production system, develop a series of software for industry applications, and double the overall production efficiency. The project has applied for 27 patents, 21 software copyrights, and published more than 60 papers. The formed series of products has sold more than 2000 sets in the past three years, with sales reaching 410 million yuan and realizing profits of 62.04 million yuan. Multi-platform laser radar is the first in China, realizing multi-purpose of one machine on UAV, vehicle, backpack and other multi-carriers, supporting self-developed point cloud comprehensive processing software, laser point cloud mapping software, power line laser radar inspection and analysis software, point cloud comprehensive information extraction and collection management software, etc. It has realized large-scale application in terrain survey, mine survey, highway survey, electric power inspection and other industries, with high operation accuracy, greatly improving efficiency and saving cost. Domestic authoritative experts such as Ning Jinsheng, Wang Jiayao, and Li Jiancheng, academicians of China Academy of Engineering, believe that the project has strong technological innovation, a high degree of industrial transformation, and significant economic benefits. The technical level has generally reached the leading level of similar products in the world. The new spectral multi-platform laser radar products have improved the level of mobile measurement equipment such as drones and vehicle-mounted vehicles in my country, and improved my country's ability to acquire geospatial information.
