Compared with autonomous lidar, lidar for geomatics is faster to apply. In the process of rapid national development, lidar, as the core device of three-dimensional scanning, has also ushered in a new wave of development.
Lidar can achieve large-scale popularization in various industries, not only thanks to the improvement of lidar performance, but also due to the reduction of cost. He has been deeply engaged in the field of geospatial information for many years, with profound accumulation and rich technological achievements. In the UAV laser scanning system, the GNSS/INS combined positioning positioning measurement system (POS) is the core component, which determines the final performance of the system. Due to the unique domestic intellectual property POS system, the cost of the UAV laser scanning system is greatly reduced, so it can launch low-cost, high-quality and cost-effective laser scanning products. International products are not at the expense of quality, but by technological innovation and the competitiveness of mastering core technologies.
Power patrol
The laser point cloud data collected through the line patrol is processed into a standard DEM, combined with the classified point cloud can realize the three-dimensional digitization of the power line, restore the surface form along the power line, the surface attachments (buildings, trees, etc.), the three-dimensional position and model of the line pole tower, and enter the attribute parameters of the line, which becomes an important basis for realizing the management of the line asset. Identify tall vegetation, high-rise buildings, crossing lines and other interesting features, analyze the topological relationship and interaction between each other, output icons to prompt the WeChat inspection area, and detect whether the distance between buildings, vegetation, cross spans and other lines meets the operating specifications.
1. Airborne lidar system has the advantages of rapidly obtaining high-precision laser point clouds and high-resolution digital images, whether it is the design of the direction of the new line, or the inspection of the dangerous points of the existing line, the management of the line asset and various professional analysis, which bring the operation mode and technical advantages that the traditional surveying and mapping means do not have;
2. The airborne lidar scanning system integrates laser sensors, positioning and capitalization systems, high-resolution digital cameras, computer control units, unmanned aerial vehicle flight platforms, etc., with high integration, light quality, high data accuracy, low operating costs, few restricted factors, simple operation, and easy to carry.
Forestry surveys
International navigation high-precision airborne lidar system, related forestry survey, vegetation analysis software, can quickly save all aspects of the information of the vegetation under investigation through three-dimensional point cloud data, on the basis of this information, it can be convenient to extract plant canopy, chest diameter and other data, facilitate forestry data analysis and preservation, through the software automation extraction parameter module, you can obtain the required values in large quantities and efficiently, compared to traditional data collection methods, can be both fast and accurate, Moreover, in the key parameters of obtaining some vegetation, it is not necessary to cut down trees to obtain vegetation information, which ensures the sustainable development of ecology and minimizes the harm to the environment of forestry surveys.
Water conservancy resources
In view of the common operating environment of water conservancy and hydropower and the characteristics of laser point cloud data itself, airborne lidar technology combined with the application of traditional photogrammetry technology in topographic mapping in high-density vegetation coverage areas, focusing on the classification method of airborne lidar point cloud data, from data acquisition, pre-processing, point cloud filter classification, air three encryption to each link of the map, to achieve the extraction and mapping of surface information in high-density vegetation coverage area. Airborne laser scanning system has great advantages in regional complex multi-vegetation surveying, and has broad application prospects in the field of water conservancy and hydropower engineering mapping in the future.
