3D Laser Scanning and Surveying

3D laser scanning is very helpful in surveying and can yield faster, more perfect results than other methods. It can be used for getting accurate measurements for complex objects and buildings, both in outdoor and indoor projects.

3D laser scanning methods are used by setting out engineers at sites. The selection of the equipment will depend on your project and environments, and the setting out engineer should be able to assist. Various equipment are capable of handling various challenges, including narrow job sites, dusty or humid areas, in rain or direct sunlight applications. However, most importantly is the ability to capture detailed data at the target distance.

Modern equipment used have cameras and intuitive touch screens that deliver extraordinary user-experience. For instance, they have large cameras that capture details while providing natural color overlay to scan data in extreme lighting conditions. The touchscreen is large in size and offers clarity, while allowing quick input.

If you are looking for a 3D laser scanning equipment, it is important to check for the one that is light in weight, small in size and with a longer battery run-time per charge, if the target is an outdoor project. These equipment also have differing scanning ranges. For instance, you can get portable devices that can scan up to 150 m.

A scanning device should be built in such a manner that it is not affected by dirt, dust, rain and fog among other intrusions, when you go for outdoor projects. With some devices used by setting out engineers, you can connect to other accessories. For indoor applications, you can get devices used by setting out engineers that can perform over 70 m and these are also ideal for small area applications.         

Many modern equipment also capture and store data for future analysis and reference. You should also go for equipment that can perform in bright sunlight and one that can do remote scanning. Some do have data sharing capabilities.

Instead of purchasing the equipment, you can hire a qualified and experienced setting out engineer to perform the scanning operation, in case you only need the service only a few times after a long time. It is important to look for someone with experience in using this method under varying conditions and challenges.
