I was unable to get boost's json parsing to run in the ~4 hours I tried. The syntax is overly verbose, there is little documentation, and there are few tutorials on google. I was able to get it to run right away with nlohmann's json library (matter of 30 minutes). Contributor Auth...
Taking raw Lidar data and turning it into a 3D model with no additional information, such as a building’s polygons, is an essentially automated process. Simply download the data in the raw LAS format to create Digital Surface Model (DSM). The process is very simple, follow thisStep-by-s...
Just find the source code from patch_match.cc, will try some parameters to see if I can get a better result. Also, is there any paper about manually selecting source images for each target by using proper relative pose? In colmap, the sparse model is used to automatically select ...
From this, a higher density of points is obtained with improved resolution. Afterward, a mesh surface is created and textured using the image collection. The extracted GNSS information from the metadata of each image is used to locate geographically the reconstructed model in the real world ...

scenarios that were tested, the Time-SIFT method allows the use of crowd-sourced data in a very satisfactory way in terms of reconstruction quality, with a standard deviation of 8.6 cm. Keywords: citizen science;SfM photogrammetry;risk assessment;rockfalls;Time-SIFT method...
Here, the two most useful approaches are airborne LiDAR and Structure from Motion (SfM) [24]. Both can resolve height differences down to centimetres at a horizontal resolution of decimetres. SfM, in particular, is a technique that can be applied using digital images collected from a ...
UCH artifacts can also pose threats to coral reefs by causing physical damage to benthic organisms and releasing pollutants into the environment [6,7]. Live coral and three-dimensional (3D) habitat complexity play important roles in supporting biomass and biodiversity and facilitating key ecological ...
