How do laser scanners work

Desktop Scanners are the ideal option to quickly scan complex shapes and geometric data from small objects. Producing 3D scans of the highest quality. To achieve optimal accuracy and results with 3D laser scanning it is often necessary to apply an anti-reflection coating. Helling 3D Scan Spray is especially designed for this purpose. Volume Graphics offers a range of products for the visualization and analysis of CT data and has become a virtual standard for industrial voxel data analysis.

ExactFlat enables manufacturers to design, flatten, conduct pattern engineering, nest, cost and create manufacturing and business documentation all on one platform.

Terrestrial 3D scanning is a ground-based technique for collecting high-density spatial imaging with millions of coordinates quickly and accurately.

With Laser Design you know your ITAR project is not only compliant but being fulfilled by a company that is registered. Metrology grade Computed Tomography CT inspection allows a complete 3D capture of complex internal geometry of parts without needing visual access — the process is nondestructive. Reverse engineering using 3D scan data is the most efficient way to generate a CAD model from a physical object that has any kind of complex or freeform shape.

Helping to solve your most demanding dimensional inspection issues, digitizing, calibration, certification and all other facets of manufacturing that have to do with 3D metrology. If you have a scanner but would like help taking your point clouds to CAD format then let the 3D experts help! Everything from small plastic parts, blades to entire ships and buildings. Moving from 2D to 3D improves how your ideas and concepts are shown and communicated.

True, the technologies that make it possible are very advanced and quite amazing. But behind the mirrors—found in the laser probe without any smoke —there is a lot of know-how and experience that makes the laser scanning experience seem so easy to Laser Design customers.

Read on or watch our video on What is 3D Scanning? What is 3D Scanning? Here are some of the reasons why organizations use 3D scanning for surveys. Laser scanning is the speediest land surveying method out there. Laser scanners can collect millions of data points in seconds, reducing the time and human resources needed to complete surveys. This method of surveying is perfect for projects that require a quick turnaround. For projects that require information from vast landscapes or extensive networks of roads or railroads, laser scanning systems can be mounted onto land-based or aerial vehicles.

The systems can then gather data from all of the necessary areas in a short space of time. Before laser scanning systems came about, certain areas were off-limits to surveyors. But with vehicle-mounted LiDAR systems, organizations can collect point cloud data from even the most inaccessible of areas. For example, drone-mounted LiDAR can survey unsafe sites and structures.

Because laser scanning is a non-contact surveying method, it can also survey sensitive objects or areas, such as vulnerable historic sites.

Perhaps the biggest advantage of laser scanning is that scan data can create 3D CAD models. These 3D digital models can be used to analyze topographic features, structures, and transport corridors. They can also be used to simulate construction or urban planning projects. Laser scanning is utilized by many high-value, government-backed, and privately funded projects such as national defense and road surveying.

Some of its other well-known applications are listed below. Usually, the spatial scanning process is time-consuming, and one small mistake could affect the entire project. Laser scanners not only reduce the time taken in plotting and spatial scanning but also improve the planning process and considerably cut down the number of errors during the data collection.

Because of the value laser scanners add to spatial scanning, researchers use them for mobile mapping, surveying, scanning buildings — and their interiors. Laser scanners help reduce turnaround time for road surveys and traffic construction analysis from weeks to a matter of hours. Urban topography is an interdisciplinary study of towns — their forms, layouts, architectural history, geography, etc. This is a critical process as it requires regular, accurate data collection by urban planners who use laser scanners to collect and process data before beginning development work.

Laser scanning can also be applied to civil surveying, reverse engineering, mining, and archaeological projects. Find out how TopoDOT can help you streamline your point cloud processing efforts by signing up for a free demo today or book at Discovery Call with.

Thank you so much for sharing this information about what is laser scanning and how can it be used. This is very nice and inspiring!! Thanks for sharing and look for more in future!! I hope you keep update us with such great tips and information in future too. Model points are created using the known camera position and information from the light pattern hitting the object.

Structured light scanning is used in facial recognition technology, reverse engineering, design, manufacturing, and remote environment recognition two cool examples are mapping the seafloor and the inspection of railway tunnels. The known value of the speed of light is what makes this method of calculating distance possible. The technique is often used in range imaging camera systems, or 3D cameras. Time-of-flight technology is highly sophisticated in terms of quality but can be an expensive option usually reserved for scanning large environments and buildings.
