Research on 3D laser scanner technology
Perhaps speaking of 3D laser scanning technology, most people still can't understand it well. But if you talk about 3D laser scanners, you probably know. The 3D laser scanning technology is mainly composed of 3D laser scanner and system software. It is characterized by the ability to acquire spatial 3D models of close-range static objects quickly, accurately and conveniently, so as to further process and analyze the data. However, laser scanners are characterized by high precision, flexibility, and efficiency. Objects scanned by a 3D laser scanner are usually more complex, and a single scan of an object can only obtain 3D data of one face of the object under test. If you want to get all the appearance models, you must collect the 3D model of the object from different directions and directions, and integrate the obtained data to get the appearance model of the object. The 3D laser scanner on the ground comes with point cloud processing software, which will establish a corresponding 3D model based on point cloud data. Point cloud data processing usually includes the following aspects: noise removal, surface reconstruction, multi-view alignment, data reduction, and so on. If the depth data obtained by the two scans are registered in the same coordinate system, two layers of data will appear in the coincidence, which brings redundancy and inconsistency of the data. The depth data obtained by laser scanners are usually discrete point clouds, which do not accurately indicate the appearance of actual objects and scenes. 3D laser scanning technology is a new technology. It is another technological revolution that has emerged after GPS technology. It is also one of the most advanced mapping technologies. Because the ground three-dimensional laser scanner can acquire the three-dimensional space coordinates of the object's appearance with high speed, high density and high precision, and does not need to touch the object to be measured. Therefore, the 3D laser scanner has been widely used in 3D modeling.
