3D laser scanning technology or popularly known as LIDAR is a Light Detection and Ranging Technology that helps to create an accurate 3D representation of any given earth structure such as buildings, dams, roads, forest, etc. The technology consists of emitting millions of infrared light pulses every second from a laser scanner to the target and recording the time of travel. Knowing the speed of pulse and time of travel, the location of target coordinates can be found, which thus finally results in “point cloud” consisting of millions of data points with X, Y, Z coordinates. This data can then be used to prepare the 3D map of any given structure after removing the unwanted noises. The entire laser scanning can be completed in just 3 minutes of time with modern ground based terrestrial laser scanning systems having an accuracy of 6 mm. The major advantage of modern scanners is that it provides actual photographs of the target objects (natural features or man-made structures) in addition to the point clouds, which makes registration of multiple scans much easier during post processing. The ground-based LIDAR system can be used for various civil engineering applications like capturing existing building’s exterior, interior, preservation of heritage buildings, area volume calculations, highway asset management, identifying structural deformation, slope instability analysis, etc. Even thermal properties of objects can be studied using LIDAR systems. Many civil engineering construction companies in India already have started using LIDAR systems for monitoring their day to day construction activities as the data acquired through LIDAR is reliable and accurate. The present workshop aims to give the participants a full-fledged knowledge of the latest ground-based LIDAR technology with more focus on practical demonstrations rather than theoretical lectures. At the end of the workshop, the participants will be well versed with the working principle of LIDAR and will know how the LIDAR technology can be used to capture the 3D of any given structure.
