What factors you need to consider when buying a 3D Laser Scanner
Purchasing a 3D Laser Scanner can be a significant investment and should be a carefully considered purchase, to match your needs and requirements. Red Laser Scanning and our team of professional surveyors are here to discuss and explore what factors are critical to factor in and research before making a big decision. Our 3D Laser Scanning company use FARO S70 3D Laser Scanners for our project, so how did we finalise the decision to purchase this specific 3D Laser Scanning equipment? Let us dig deep into Laser Scanning technology and find the exact requirements for you.
HDR Imagery & Quality
The quality of images produced from scanners should be of high-quality and clear if the purpose of your 3D Laser Scanner is to provide accurate 3D Visualisations and Models. What differentiates a terrestrial laser scanner for example to a mobile scanner, is that is it less quick, but contains that HDR imagery which becomes close to the quality of a DSLR Camera. If looking to capture higher-quality imagery and more accurate data to produce your as-built 2D Drawings or 3D BIM Models, a terrestrial laser scanner is more favourable than a mobile laser scanner.
Accuracy & Speed
We hear how 3D Laser scanners can capture up to millions of 3D points per second, but what does this exactly mean to you? It is always a good idea when researching to compare the speed of 3D Laser Scanners, such as a Leica RTC360 which measures two million points per second, as opposed to one. Of course, all of these factors depend on your committed budget and how critical you think it is to access this speed.
Accuracy is also extremely critical and should be a crucial decision when purchasing 3D Laser Scanning equipment. Scanners may capture everything visible within 70 metres with an accuracy of +/-1mm, or even 130 metres with the same accuracy. This should be explored and examined depending on the size and scale or majority of your projects.
Accuracy in 3D Laser Scanning indicates the range of error that is immanent in the measurement. Ideally, we are not looking for inaccurate results and measurement errors when producing plans or models through 3D Laser scanning. Our 3D Laser Scanning company notes that this is a massive factor before any purchases are made.
Purpose & integration with other instruments
If you are looking to scan sites on a larger-scale, or perhaps areas which are quite restricted and inaccessible, consider the integration of other instruments such as GPS or Total Station etc. The additional instruments, or the choice for scanning a complex site, is based on the level of visibility of the terrain features and required coordinate system, primarily focusing for topographical surveys. Unmanned aerial systems also can be purchased for inaccessible sites. For our drone survey services, we use DJI Phantom 4 Pro.
Informing yourself on the right tools and additional equipment along with your 3D Laser Scanner needs to be reviewed depending on your project requirements. Make sure to consider these factors and enquire what the 3D Laser Scanner can provide as well as the extent of its potential.
