Frequently Asked Questions About 3D Laser Scanner

The unprecedented speed of technological change has made the 3D laser scanner a very common device in many industries today. 3D measurement tools are cost-effective methods to capture data so individuals can visualise as well as analyse objects quickly and efficiently.


How does 3D scanning work?

3D laser scanning involves digitally capturing and measuring the details of physical environments or objects with laser light. A laser scanner sends light pulses at high speeds which reflect off objects and return to the scanner’s sensor.

3D laser scanning devices allow for more precise models of a given space and reduces the possibility of human error. The greater the number of scans taken, the more accurate the results will be.


Will 3D laser scanning destroy the object? What can be scanned?

3D laser scanners make use of non-contact and non-destructive technology that does not destroy the object. The scanner emits a laser beam which will reflect off objects and return to the scanner’s sensor.

Many types of objects can be scanned. Due to their odd angles, some objects may require extra scans to get enough information.

3D scanning is mainly used for objects with complex shapes and contoured surfaces, even in darkness. In these cases, due to the great amount of data needed, it is impractical to use traditional measurement methods like gauges, callipers and coordinate measuring machines.

What are point clouds and why are they important?

Point clouds represent spatial data as a collection of coordinates. They deliver data sets so individuals can visualise and analyse the 3D data.

In other words, for better visualisation and analysis, point clouds are points in a 3D series that depict an environment or object that was digitally scanned.


Which is the best 3D laser scanner?

Every object is different so deciding which 3D laser scanner to use requires an evaluation of various factors. It is generally recommended to follow the few tips below:

Accuracy: The accuracy of data is of the utmost importance because many individuals rely on the 3D data to make decisions. To ensure that the laser scanner meets the optimal standards, the machine should be calibrated on-site.

High resolution: Choose a high-resolution 3D scanner if you require a detailed 3D model of the object.  Do note that the higher the resolution, the longer it typically takes to process the data and the bulkier the scanner will be.

Up-to-date software: The software powers the 3D scanner. An updated software can handle data quickly and are usually more user-friendly

Speed: Many manufacturers prefer a 3D laser scanner that has a high number of frames and a high number of points captured per second.

Object being scanned: The best scanner depends on the size of the object, the material of the object’s surface and the amount of detail one wants to capture. Different 3D laser scanners are recommended for different uses.
