Choosing the right technologies, with the best and most appropriate set of functions, is pivotal in Geomatics. Here at Merrett Survey Limited, we are constantly looking for ways to enhance the efficiency of our laser scanning methods with the view of producing the most efficient and accurate results as possible. Due to their capability to take 3D measurements, laser scanning systems are utilised to survey all types of environments, whether it’s buildings, road networks or railways for example.
Laser scanning can be summarised in a few simple sentences. It is a technology that allows us to capture environments in 3D with speed and accuracy. Each surface that the laser comes into contact with is reflected back and recorded as a surface point, before being assigned a colour and surface reflectivity. Hundreds of millions of data points can be captured in a single session which, when combined, are called a point cloud.
Benefits of laser scanning:
In it simplest form, LiDAR stands for light detection and ranging, just as radar stands for radio detection and ranging. Initially, LiDAR scanners were attached to aeroplanes in the 1960s and t wasn’t until the 1980s that the technology became appropriate to use in the geospatial industry. These were utilised as commercially viable GPS systems, which provided industry professionals with the ability to create concise, geospatial measurements.
In the surveying industry, we often use the phrase LiDAR for aerial surveys and laser scanning for ground based work, but the principle is the same – using a laser beam to measure the distance to an object.
With many different technologies on the market, there are a vast range to choose from when thinking about your client needs and specifications. However, the Leica RTC360 is an advanced and highly sophisticated product which ticks all of our boxes.
The 3D laser scanner, complete with HDR spherical imaging system and Visual Inertial System (VIS) allows for real time registration. With its ability to scan large scale areas with immense speed, precision and agility, the RTC360 is the ideal tool to further our laser scanning and LiDAR expertise.
Some key benefits of the Leica RTC360 include:
Speaking of the benefits of the RTC360, owner of Merrett Survey Limited, Peter Merrett said: “We have a reputation for applying the latest technology, yet we only apply it when it has been proven to bring genuine benefits – either in terms of speed or accuracy and quality of the end product. This instrument certainly speeds up our fieldwork. Plus, on the quality front, the built in HDR camera is of very high quality.
“The photographic part of the scan process tends to slow down the scanning work considerably, although, with this laser scanner, the imaging time is only 2 minutes per set-up. This enables us to colourise the point clouds we produce to a very high standard and also gives the client a greater insight into the structure or asset we are surveying”.
Whether its laser scanning large storage tanks or vast areas of land, laser scanning technology such as the RTC360 allows us to deliver fast, pinpoint results. Contact us to find out more about our laser scanning and LiDAR services in greater detail and to discuss the full uses of the Leica RTC360.
