Modeling of different geometrical properties by terrestrial laser scanning

Laser scanning technology is an optical-mechanical measuring technique. By means of laser scanning, three-dimensional position information of the object and its immediate surroundings is obtained in a very short time. The distance between the receiver and the object is determined by the travel time of the laser beam, an electromagnetic energy. This measurement method, which is referred to as lidar technology, provides fast and accurate solutions for 3D data acquisition of space or objects by appearing as terrestrial laser scanning, mobile laser scanning and aerial laser scanning on different platforms. Today, terrestrial laser scanning technology; architectural documentation, archaeological studies, 3D modeling, mining studies, deformation analysis, forest inventories, such as the use of various engineering applications can be solved more easily with different engineering problems. In addition, laser scanning technology allows rapid reconstruction of complex scenes through dense point clouds. In this sense, the rapid documentation of complex scenes in which accidents or judicial offenses occur, the identification of evidence that constitutes evidence for post-incident analysis, and terrestrial laser scanning within their digital archive is an important tool to accomplish this task. In this study different geometric structures are modeled in different applications with terrestrial laser scanning. SCENE, 3DReshaper, JRC 3D Reconstructor software were used to evaluate the data.
