Mobile laser scanning (MLS) is a technology used for collecting three-dimensional (3D) point clouds and detail imagery of large-scale environments.
A mobile laser scanner typically consists of a laser scanner unit, a GNSS (Global Navigation Satellite System) receiver, and an inertial measurement unit (IMU) mounted on a moving platform, such as a vehicle or aircraft. The laser scanner emits laser beams that bounce off the surrounding objects and are then detected by sensors in the scanner unit. By measuring the time it takes for the laser beams to bounce back to the sensor, the scanner can determine the distance between the scanner and the objects in its environment. The IMU in conjunction with the GNSS are used to measure the scanner's position and orientation, allowing for the accurate registration of the 3D point cloud data.
Mobile laser scanning is used in a variety of applications, such as reality capture, road and railway surveys, urban planning and mapping, forestry and agriculture management, and construction and engineering projects. The technology allows for the efficient and accurate collection of 3D data, making it possible to quickly create detailed and precise maps of large areas.
One of the advantages of mobile laser scanning is its ability to capture data from hard-to-reach or dangerous areas. For example, a mobile laser scanner can be used to survey the lanes of a busy freeway or the interior of a tunnel, where it may be difficult and unsafe for surveyors to access due to traffic or restricted access. Additionally, mobile laser scanning can be performed at high speeds, allowing for the collection of large amounts of data in a short amount of time. This can be particularly useful in transportation planning, where the accurate measurement of road or rail infrastructure is critical.
Another advantage of mobile laser scanning is its ability to capture detailed information about an environment. The technology is used to produce high-resolution 3D point clouds, which can be utilised in the creation of detailed digital models of an area. This information can be used for a variety of purposes, such as creating virtual reality environments, designing, and visualising construction projects, or monitoring changes in an environment over time.
The Leica Pegasus TRK and BLK2GO are both examples of high-quality mobile laser scanners that are available on the market today. These devices are designed to capture highly accurate 3D data from the real world, allowing users to create detailed maps, models, and measurements that can be used for a wide variety of applications.
The Leica Pegasus TRK, uses LiDAR, cameras, and other sensors to capture detailed data about the environment. The TRK is designed to be mounted on a vehicle, allowing for rapid data collection over large areas. The TRK can capture 3D data and high-resolution imagery making it useful for a wide range of applications.
The Leica BLK2GO is a handheld LiDAR scanner that can be used for both indoor and outdoor mapping. The BLK2GO is designed to be portable and easy to use, making it ideal for quick mapping jobs or for use in hard-to-reach areas. The BLK2GO can capture 3D point cloud data and imagery.
Overall, both the Pegasus TRK and the BLK2GO are excellent examples of the power of mobile laser scanning technology. Whether you are a surveyor, engineer, or architect, these devices can help you collect accurate and reliable data that can be used to make better decisions, improve safety, and increase efficiency in your work.
In conclusion, mobile laser scanning is a powerful technology that allows for the efficient and accurate collection of 3D point cloud data. With applications in a wide range of industries, mobile laser scanning is becoming an increasingly important tool for mapping and surveying large-scale environments.
