Laser mapping is a rapid non-contact technique of data acquisition and is therefore suited to environments where conditions provide for health & safety implications such as in areas of landslide or rock fall, or access to the area is limited, such as for rail or road surveys or coastal monitoring.
The remarkable accuracy of the mapped points provides a highly realistic image of the real world, which can be used in various areas of geomatics and engineering.
The 3D nature of the data capture and resolution of that data makes the technique suitable for the surveying of complex structures and structural elements within both the man-made and natural environments.
Scanner Technology
The 3D laser scanner is a surface imaging system based upon accurate laser distance measurements. The 3D images are gained by performing a number of independent laser distance measurements in different, but well defined angular directions. This distance data together with the associated angles form the basis of the 3D images, also commonly referred to as a point cloud.
Additionally, combined with a high resolution digital camera, every scan point can be assigned a colour using the image data.
