What is 3D laser scanning and what are its benefits for businesses and consumers alike

Lidar, or Light Detection and Ranging, is a remote sensing technology that uses laser light to create detailed 3D maps/models of an area. Lidar systems are often used for surveying and engineering applications, as they can quickly and accurately collect data about the shape and contours of an area. BIM, or Building Information Modelling, is a popular application for lidar data. BIM software allows architects and engineers to create virtual models of proposed buildings or structures, allowing for accurate assessment of construction projects. Lidar data can also be used by businesses and consumers to create 3D models of their homes or office space. These models can be used for base build contractors, interior design, Process plants, oil refineries, chemical plants, heavy industrial corridors, and Factories to get a better understanding of the layout of a space. In general, 3D laser scanning provides a powerful tool for businesses and consumers alike, offering a variety of benefits and applications.

The different types of 3D laser scanning technology that are available on the market today

Terrestrial laser scanning is a type of 3D laser scanning that is often used for surveying and mapping purposes. Terrestrial laser scanners are usually mounted on tripod stands, and they use a laser beam to scan the ground in a 360-degree field of view. The data collected by the scanner can be used to create detailed 3D models of the ground surface. Airborne laser scanning is another type of 3D laser scanning. Airborne laser scanners are usually mounted on aircraft, and they use a laser beam to scan the ground from above. The data collected by the scanner can be used to create detailed 3D models of the ground surface, as well as to create digital maps of the area scanned. Handheld laser scanners are smaller, more portable versions of terrestrial laser scanners. They can be used for surveying and mapping purposes, but their small size makes them better suited for scanning small areas or objects. Mobile laser scanning is a type of 3D laser scanning that is done with a mobile device, such as a smartphone or tablet. Mobile devices can be used to scan small areas or objects, and the data collected can be used to create 3D models, but these are less accurate and cannot capture denser areas.

How to choose a 3D laser scanning company that is right for your needs

When choosing a 3D laser scanning company, it is important to consider its in-house capabilities. Does the company have its own BIM modelers? If not, do they have a network of reliable BIM modelers that they work with on a regular basis with all the quality checklists? What is the company's experience with scanning and BIM modelling? Do they have examples of projects that they have successfully completed? At Desapex we can also provide a detailed checklist for getting started with your laser scanning projects, whether it's your first project or 100th project we provide the same level of expertise where we ensure you get the right information at right time.

It is also important to make sure that the company you choose has the ability to register point clouds. This is a critical step in the BIM modelling process, as it allows for the accurate registration of multiple scans into a single coordinate system. Without this step, it would be not easy to create an accurate BIM model.

Another important consideration is the company's ability to create 3D models from point clouds. This is typically done using computer-aided design (CAD) software. Does the company you are considering have experience with this type of software? Do they have examples of 3D models that they have created?

Finally, you will need to decide if you want the company to produce a digital terrain model (DTM) or a lidar point cloud. A DTM is typically created from airborne laser scanning data and is used to represent the topography of an area. A lidar point cloud is typically created from terrestrial laser scanning data and contains information about both the topography and the geometry of an area. Each type of data has its own advantages and disadvantages, so it is important to choose the one that best suits your needs.

The steps involved in getting a 3D laser scan done:

Requirement Document: The first step is to provide the service provider with a requirement document that states the specific needs of the project, including the expected level of detail and output. This document will also include any information modelling requirements that need to be met. Once the service provider has a clear understanding of the project requirements, they can begin to create a 3D model.

Level of detail: The level of detail in a 3D laser scan can vary depending on the needs of the project. For example, if the goal is to capture an accurate representation of a building, then a high-resolution scan will be necessary. On the other hand, if the goal is simply to identify potential problems with the structure, then a lower-resolution scan may be sufficient.

Expected output: The expected output from a 3D laser scan can also vary depending on the project requirements. In some cases, a 2D map or drawing may be all that is needed. In other cases, a more detailed 3D model may be required. Regardless of the specific output requirements, it is important to communicate these expectations to the service provider before the scan is performed.

One-time or recurring job: Finally, it is important to determine whether the 3D laser scan is a one-time job or if it will need to be performed on an ongoing basis. This will impact the overall cost of the project and should be taken into consideration when budgeting for the job.

What goes wrong usually: Most of the time when a client is looking for an as-built survey, they start comparing the LIDAR with traditional surveying which does not give a full picture of the situation, the points captured during the traditional survey are not continuous and always there are gaps in between, but whereas in HDS lidar scanning the complete 360 degrees of the area will be captured and even panoramic images can be extracted. The efforts and the output of these two methods are completely different and reflect on the timeline and cost associated with them. At Desapex we aim to provide this solution at a very affordable price and make sure your end objectives are satisfied.
