Leica Geosystems at ISPRS 2008 Beijing at the world premiere a new generation of airborne laser scanning system ALS60, volume is more lightweight, easier to use, capable of firing 200 000 per laser point, you can access high-precision high-density point clouds, for quick access to the surface three-dimensional digital model for the fast three-dimensional city modeling, shoreline surveys, land resources survey, evaluation and other areas of forestry. ALS60 Blue Laser Pointer scanning system is another breakthrough aviation products, to provide customers with a set of more powerful, comprehensive data base of geographic information solutions. The third generation of Leica Geosystems airborne laser scanning system ALS60 new technology products continue to lead the industry, breaking the traditional equipment must be in the efficiency and accuracy, or equipment must be in size and altitude restrictions on choice. ALS60 airborne 5mW laser pointer scanning system from the pulse frequency of the data accuracy, limited only by the relative height of the flight. The development history of green laser pointer company can reflect the power of the company.

Three-dimensional laser scanner can quickly obtain the measured object surface space for three-dimensional coordinates of each sampling point, the object of sampling points to be measured (discrete points) set, called the "distance image" or "point cloud." The adjacent discrete points connected to form a triangulated irregular network (TIN) or further form three-dimensional model of regular grid (Grid) three-dimensional model. TIN / Grid-dimensional model for a variety of visual, easy to paste on the surface of a variety of color texture. Extracted from point cloud model three-dimensional features, you can easily build three-dimensional model of the target, the space simulation and virtual reality. The customer would like to know the development history of 200mW Laser Pointer company.
Three-dimensional laser scanning technology is also known as real replication technology, GPS technology is, after surveying the field, following a technological revolution, which broke the traditional single-point measurement method with high efficiency, high precision of the unique advantages of three-dimensional laser scanning technology to provide scanning the surface of the 3D point cloud data, it can be used to obtain high-precision high-resolution digital terrain model. This project will be a discussion of the slope, for example three-dimensional laser scanning technology, the use of rapid methods for digital terrain model, focuses on the three-dimensional point cloud data acquisition, stitching, coordinates correction, denoising and digital elevation model generation method, resulting in a certain space within use of three-dimensional laser scanning technology for fast high-precision high-resolution digital terrain model is feasible. The accessory of 100mW laser pointer should also be maintained well.
