Laser scanners have made working on sites more accessible and more efficient without losing accuracy and detail of the scene. Regardless of the obstructions and the size of the site, the laser scanner gives the most accurate results possible. This high accuracy reality capture is like a 360-degree picture.
When working in a construction site, laser scanning reduces the risks and costs. Topographic surveys are detailed and complete without the necessity of having to go back to the field while also providing users with faster and more accurate results. Users can revisit the scan data in their computer if anytime measurements are needed, verify information, and much more since 3D scanning data is all digital and can be used with most drafting software. They are making it easy to review proposed CADD designs in a real-world context. Information can also save you and your clients a lot of time and resources, as well as improving your business with higher revenues and profits.
How does laser scanning work? It has two essential parts, fieldwork and office work. Fieldwork is when the scanner captures the scene; this scanning process includes taking panoramic pictures for more realism. Start by positioning your scanner where it can see and read what you want. To capture a large site, place the scanner on different vantage points that are points-based on-site logistics and scanner capability. Following this, take multiple scans that can then be put together automatically either while scanning or later on a computer. Scans can also be geo-referenced to coordinate system, just like a standard survey. Apart from measuring distances for each distance, additional critical data is also recorded. The result the scan gives is a 3D representation of the scene called point cloud. Matching photos can be taken add color and texture to the point cloud; this can be done by using a camera already in the scanner or an external camera, which then automatically merges the photos with the scan data.
Following is Office work when all the data taken at the fieldwork is uploaded to software and converted into the products and deliverables needed. Depending on how well equipped the scan is, the uploading step can be done right there, or it can be done later by post-processing the set of scans that were taken. Laser scanner software makes the work more efficient and easier to access. There are different types of software, such as Plugin software, which makes everything regarding office work faster and easier. It allows users to work more efficiently with point cloud data directly within CADD virtual reality or asset management software. The scan software enables users to work on their project whenever they need it, in multiple formats 2D, 3D, panoramic, fly-throughs, and many more.
There are different types of scanners, but they all share a fundamental principle. Their technology is advanced but easy to use. How does it work? It starts with the laser scan that emits a rapidly continuous laser beam. As it emits the laser, it automatically rotates around its vertical axis.
Meanwhile, a fast-spinning or oscillating mirror also moves the beam up and down. The result is a systematic sweeping of the beam over the area. When the laser hits an object, some of its energy bounces back to the scanner. If the returned energy is strong enough, the sensor detects it, and the timer uses it to calculate the distance from the scanner to the object.
Laser scanners offer the most efficient workflow options when dealing with different site logistics. They make it easier to achieve results the can be trusted in a simple or complex site. Scanners produce more than just a picture; it gives accurate survey data that is easy to work with once it is downloaded into a software.
