“…Minerals 2020, 10, 174 3 of 19 template for the application of UAV in mapping river landscape as a research tool for this type of landscape [22]; the limits and advantages of photomodeling compared to structured light 3D scanning systems were demonstrated by Catalucci et al [23]; Fraštia et al provided a comprehensive and accurate macro-view of the morphology of inaccessible rock towers and blocks using LiDAR, which could not be obtained from field survey [24] and other studies. For related industries, such as civil engineering and architecture, we recognize TLS applications in documenting the actual state of buildings and their deformations [25][26][27]; in mechanical engineering to document complex machinery [28,29]; or transport engineering [30].…”

“…However, this approach was mainly developed to extract the types and locations of pavement cracks rather than the crack widths. Jiang et al [ 27 ] used the inverse distance weighting method to generate point cloud raster images to realize crack detection for post-earthquake buildings. However, this required many shape features to remove false cracks.…”

“…In recent years, terrestrial laser scanning technology has been widely used in different fields such as three-dimensional modeling, heritage protection, deformation monitoring, and forest structure investigation [13]. Experiments using TLS for continuous monitoring and analysis of building structural component damage demonstrate its effectiveness in structural modeling and analysis applications [14,15]; scanning assessment and 3D modeling of ancient buildings using TLS propose effective solutions for the conservation and maintenance of ancient buildings [16]; in civil engineering applications, high precision data obtained by TLS in combination with least squares are used for the quality assessment of building plane regularity [17]; scholars applied "alpha shapes algorithm" to LiDAR data contour line extraction and regularization for buildings and demonstrated the accuracy of the algorithm in LiDAR point cloud data extraction for building contour lines [18,19]; in postearthquake building loss analysis, scholars proposed a building shape analysis model based on ground-based Li-DAR data, which effectively solved the problems of building contour polygon sequence extraction, shape discrete parameter extraction, irregular building block division, and earthquake damage analysis [20,21]. In terms of judging the degree of postearthquake building damage in the regional spatial context, scholars proposed a model based on texture extraction and fuzzy system analysis of postearthquake airborne LiDAR data, which effectively solved the problem of judging the degree of postearthquake building damage [22].…”
