The basic condition for digital development is the governance and application of data, which is the record of the measurement results of the objective world. It digitizes the entities in real life and collects them into the "virtual space". It uses high-precision three-dimensional scanning technology, uses laser as the signal source, scans the targets according to a certain resolution, and quickly models the scenes, characters and objects in the real environment, The objective facts and their development tracks are transformed into data to achieve more effective allocation and dynamic control of resources, so as to reflect the real world and realize the interconnection of everything.
The three-dimensional laser scanning technology is another new breakthrough in surveying and mapping technology after the GPS spatial positioning system. It is widely used in the fields of automatic driving and driving assistance, surveying and mapping engineering, structural measurement, historical buildings and monuments, entertainment and other related fields. Because of its automation, measuring ability, human cost, measuring speed The overall economic benefits generated by data processing efficiency are obviously superior to other measurement technologies, which is considered as a revolutionary breakthrough of surface measurement technology.
Compared with traditional measuring instruments such as total station, 3D laser scanning equipment not only breaks through the single point measurement method, but also collects more abundant data information such as 3D coordinate information and reflection intensity of points.
Non contact measurement mode: effectively avoid damage caused by contact or treatment of the surface of the object to be measured, and provide a safer and more reliable measurement method for situations that are difficult to reach by manpower.
High sampling rate: with the continuous development and update of technology, the sampling rate of 3D laser scanners can reach tens of thousands of points / second to millions of points / second, effectively reducing the working time and facilitating data storage.
Higher precision and higher density three-dimensional vector: the measured data not only contains the information of X, y and Z points, but also includes the information of R, G and B colors, as well as the information of object reflectance. It is easy to quickly obtain high-precision and high-resolution massive point data.
Strong digital compatibility: digital signals are used for storage and management, with all digital features, which is convenient for post-processing and output, and data exchange and sharing with other software.
The impact of data elements on economic development, national governance and people's lives is still growing. In the future, with the progress of technology and the development of Surveying and mapping industry, 3D laser scanning technology will be more widely and deeply applied, contributing more successful products and technologies to the national real scene surveying and mapping industry. The role it can play and the value potential it can release is huge.
