“…The parameters of Leica P40 3D laser scanner is as follows: Range accuracy:1.2mm+10ppm, Angle accuracy: Angle accuracy 8"/8" (vertical/horizontal), range noise: noise accuracy 0.4mm @10m, target acquisition accuracy 2mm (Wujanz et al, 2018). With the horizontal and vertical resolution of 2 mm for a distance of 2 m (Piech et al, 2018), Leica P40 is suitable for this case study. Based on the above research, in order to validate the feasibility of the proposed methodology, we used a Leica P40 3D laser scanner to scan a section of Xiamen Metro Line 3.…”

In the process of tunnel construction and operation, the traditional method of crack inspection in tunnel operation is through manual photographing and field recording which is not only labor-intensive with lower data quality but also hard to obtain the important geometric information of the cracks. With the development of terrestrial laser scanning technology, Three-dimensional point cloud collection from a tunnel becomes feasible and affordable. In this paper, we propose an automatic crack detection method to automatically identify the cracks from the 3D point cloud of a tunnel and also extract the corresponding dimension information of the cracks. Through a field experiment with a tunnel project, the feasibility of the proposed method was validated, and the experiment results showed that the proposed method could detect the severe crack diseases with a width of more than 0.6 mm with the relative errors of the width and the length within 10%.

“…The LIDAR technology has been already applied successfully in many geological tasks like digital and schematic models, digital elevation models (DEM), volume computation, and many others [8,12]. The research focused on the creation of a geological cross-section of a mine wall from a point cloud obtained from LIDAR measurements.…”

Application of Laser Scanning for Creating Geological Documentation

A geological documentation is based on the analyses obtained from boreholes, geological exposures, and geophysical methods. It consists of text and graphic documents, containing drilling sections, vertical crosssections through the deposit and various types of maps. The surveying methods (such as LIDAR) can be applied in measurements of exposed rock layers, presented in appendices to the geological documentation. The laser scanning allows obtaining a complete profile of exposed surfaces in a short time and with a millimeter accuracy. The possibility of verifying the existing geological cross-section with laser scanning was tested on the example of the AGH experimental mine. The test field is built of different lithological rocks. Scans were taken from a single station, under favorable measuring conditions. The analysis of the signal intensity allowed to divide point cloud into separate geological layers. The results were compared with the geological profiles of the measured object. The same approach was applied to the data from the Vietnamese hard coal open pit mine Coc Sau. The thickness of exposed coal bed deposits and gangue layers were determined from the obtained data (point cloud) in combination with the photographs. The results were compared with the geological cross-section.
