Point cloud is a revolutionary technology that helps many different industries in today’s world. However, the generation of such powerful data will not be possible without the help of scanners such as lasers.
In this article, we will take a look at the basic things anyone should know about laser and 3D scanning, its application in point cloud.
What is 3D Laser Scanning?
3D laser scanning is a digital technology that is both contactless and safe. It obtains information on the shape and distance of various elements with the help of light pulses in the form of lasers.
This technology computerizes physical attributes of any object in a space. This is very beneficial especially for subjects that are complex or irregular in shape.
Common uses of laser and 3D scanning are in video games, visual effects, robotic maps, prototyping, construction design, and even artifact or site preservation.
Output Data of Laser Scans
The main output of a 3D laser scan is point cloud data. Point cloud refers to millions of points taken from an environment that contain x, y, and z coordinates, color values, as well as luminance attributes.
Point cloud data transform into polygons or drafting models after capture. This process is also called “modeling,” also defined as the merging of the point cloud into a 3D representation.
Polygons are mainly used in reverse engineering and prototyping. On the other hand, drafting models have various applications in the construction and design industries.
3D laser scanning process need hardware tools for accomplishment. This is mainly done by a scanner which acts as the pulse generator, reflection destination, and result processor all at once.
3D laser scanners divide into three main parts: short, medium, and long ranges.
Short-range scanners can accommodate very small objects and are precise down to a millimeter or micrometer. Prototyping industries use these tools.
On the other hand, medium-range scanners have capabilities that can extend to several hundreds of meters. These are often used in site inspections, building modeling, and even interior drafting.
Lastly, long-range scanners are built for heavier workloads extending up to several kilometers.
Medium to long-range scanners is usually seen in point cloud data capture as these can be attached to Unmanned Aerial Vehicles for aerial scanning or tripods for in-land scanning.
To make full use of the point cloud data provided by a 3D laser scan, processing software is greatly needed.
These platforms help in visualizing, modeling, segmenting, and even assessing the given data so that it can be easily understood by a user.
The duties of processing software include cleaning up noise, classifying different objects, measuring the distance between two points, converting it into a 3D model, and improving overall imagery.
Traditional processing software installed in heavy-duty computer belong in this category. However, they are cost-inefficient and have high learning curves. They also need heavy systems so not everyone can use them.
ScanX is a point cloud processing software that removes the limitations of traditional data processors. It is a web-based platform that is user-friendly and collaborative at the same time.
Fast Data Collection
A single 3D laser scanner can collect and process millions of point data almost instantaneously. This greatly reduces strain in the duration and people needed for the information gathering of a certain site.
The data gathering and measurement calculation in laser scanners are simultaneously done. Thus, shorter idle times occur in the whole process.
3D laser scanners such as LiDAR can be attached to UAVs and drones which allows for the aerial view of a specific region. This is beneficial in accessing areas that are impossible to reach through in-land vehicles.

Safe Space Capture Method
3D Laser Scanners do all the heavy lifting in surveying and inspection. It does not matter whether it is a hazardous forest or cliff; a laser scanner can still provide accurate data regardless of site conditions.
Instead of facing the risks of a given environment, a surveyor can just stay safe while waiting for the whole scan to finish.
