There are two basic types of laser scanners: contact scanners and non-contact scanners. Touch scanners, as the name implies, collect spatial data from objects by physically examining them. In most cases, contact scanners are a manufacturing process to inspect small objects for one of two purposes, to make replicas of specific objects, or to further refine the dimensions of objects that exist in model format. Used in.
Non-contact laser scanners, on the other hand, do not inspect the subject and are commonly used to record spatial data for larger objects such as specific buildings, building systems, sculptures, terrain, and spaces.
In most cases, companies and organizations that use non-contact laser scanning services use, and in some cases, 3D laser scanners or triangular 3D laser scanners to scan the subject as described above. This is an overview of flight time and triangulation scanners and their general advantages. Visit:- https://flight-scanner.de/
Timeflight scanners use a laser to inspect a subject. This works by providing a laser rangefinder. The rangefinder determines the distance between the scanner and the subject by measuring the time before and after the light pulse. The laser emits a pulse that determines the time between emission and reflection on the detector. Laser rangefinders usually only reset the light time scanner several times when measuring the same object, because the laser rangefinder only detects the distance of one point in the line of sight. Cabin repairs can be done by turning the laser rangefinder or using the rotating mirror system.
The latter is the most popular because it provides higher accuracy and can be performed in less time. The biggest advantage of time flight scanners is that they can measure long distances. This makes it a great choice for scanning buildings, large monuments and large site structures. However, when you find a building or a large object, you also need to scan the details. Laser scan service providers often use triangulation scanners.
Like flight scanners, triangulation scanners use a laser to inspect a subject. However, instead of using a detector to measure the laser reflection time, a triangulation scanner uses a camera to locate the laser spot on the subject. Laser chips appear in different places within the camera’s field of view, depending on how much they are registered on the surface. Triangle scanners are named because their cameras, laser emitters, and laser spots are arranged in a triangle.
The distance between the laser emitter and the camera and the angle of the angle of the laser emitter are known, and the angle of the angle of the camera can be measured by the position of the laser point in the field of view of the camera. These three measurements determine the size and shape of the triangle and locate the angle of the laser point on the triangle. Unlike time scanners, triangulation scanners typically wipe laser stripes on objects to speed up the data acquisition process. An example of a triangular 3D laser image used to capture the details of a larger object is in the 2005 Plasticodi Roma Antica 3D laser survey by Gabriele Guidi et al.
