Terrestrial mapping in gaming refers to the process of creating a virtual representation of a real-world environment for use in video games. This typically involves using aerial or satellite imagery, 3D modeling techniques, and geographical data to create a detailed and accurate representation of a specific location. The resulting map can be used as the backdrop for various types of games, such as first-person shooters, racing games, and simulation games, allowing players to interact with a virtual environment that closely resembles a real-world location.
It can be conducted as follows:
Equipment setup: The TLS equipment, which typically includes a laser scanner and a tripod, must be set up in the area to be scanned.
Scanning: The laser scanner emits laser pulses that bounce off objects in the environment and return to the scanner, providing data on the shape and location of objects. This process is repeated many times per second to collect a large number of data points.
Data processing: The collected data is processed using specialized software to create a 3D model of the environment. The software filters out noise, aligns the data from multiple scans, and combines it into a single, seamless model.
Data analysis: The resulting 3D model can be analyzed to extract various information such as measurements, volume calculations, and surface profiles.
LiDAR (Light Detection and Ranging) scanners are often used for terrestrial scanning. Lidar works by emitting laser pulses and measuring the time it takes for the pulses to bounce back after hitting an object. The resulting data is used to create a 3D point cloud, which represents the shape and location of objects in the environment.
Lidar scanners are capable of capturing high-density, accurate, and detailed data, making them a popular choice for terrestrial scanning applications, such as:
Surveying: Lidar can be used to create accurate maps and digital elevation models of the earth's surface.
Architecture and engineering: Lidar can be used to create 3D models of buildings and other structures for design, visualization, and analysis purposes.
Environmental monitoring: Lidar can be used to monitor changes in the earth's surface over time, such as erosion or vegetation growth.
Archaeology: Lidar can be used to survey and map archaeological sites, revealing features that may be hidden underground or obscured by vegetation.
Lidar scanners come in various forms, including terrestrial scanners mounted on tripods, aerial systems mounted on aircraft, and handheld systems. The choice of lidar system depends on the specific requirements of the project.
