These two main categories are then divided into 4 sub-categories. Each has its own set of features to meet different needs.

Airborne LiDAR

The airborne type is a laser scanning system attached to an airplane, helicopter or drone. Light pulses are sent to the ground to measure distances and dimensions of the landscape below.

What are the advantages of airborne LiDAR?

– It is easy to scan large areas with no time limit, since data can be collected as long as the plane or equipment is running.

– It saves time and budget because you can cover more area in less time compared to terrestrial LiDAR.

– Compared to terrestrial LiDAR, airborne LiDAR doesn’t have to avoid obstacles on the ground such as trees, power lines, etc.

Types of Airborne LiDAR

There are two types of airborne LiDAR. They both work in the same way, but each has its own set of features.

Topographic Lidar

This type of LiDAR typically maps the land using near-infrared light. The data collected by topographic LiDAR can be used to create topographic maps of the scanned area. It is mainly used for urban planning projects.

Bathymetric Lidar

Bathymetric LiDAR is much better suited for scanning through water. It uses a water-penetrating green laser and infrared light to measure the elevation of the seafloor and riverbed. It can be used to gather information about land and sea, although it is more commonly used for coastal projects.

Terrestrial Lidar

Terrestrial LiDAR is attached to a stationary device or a tripod on the ground.

This system often scans in multiple directions using mirrors instead of scanning down. This allows the system to collect data from all sides. It is used to develop point clouds for mining, archaeology, etc.

Advantages of Terrestrial LiDAR

– Terrestrial LiDAR can work in conjunction with an airborne system to provide more information about an object and a more detailed view of a specific object.

– It is used in areas that airborne LiDAR can’t reach.

Types of Terrestrial LiDAR

Mobile Lidar

Mobile LiDAR systems are attached to moving vehicles such as cars, trains and boats. It is a good option for scanning roads and railways, and it can scan their conditions, signs, and power lines. Mobile LiDAR is often used for 3D mapping because it collects a denser database of points (coordinates). This results in more detailed 3D images and maps.

Static LiDAR

This type of LiDAR is the only one that doesn’t move. It is attached to a stationary tripod and is used to scan the entire environment or to focus on a specific area. It can scan in any direction, including upwards. The tripod can be moved to another location after the scan is complete to ensure comprehensive coverage of the area.

A short story about LiDAR technology

The LiDAR prototype was built in 1961 by Hughes Aircraft Company. The company had also built the first laser a year earlier. LiDAR systems and their uses really became known during the Apollo 15 mission of 1971 which used it to map the Moon. After, the scientific uses of LiDAR continued to evolve. Scientific research at universities such as Stuttgart in Germany has proven the accuracy of this system and the evolution of LiDAR was just beginning.

The growth

In the mid-1980s, GPS satellite communication reached its full configuration, which allowed the technology to be more and more precise. At the turn of the 90s, this allowed manufacturers of laser scanners to build LiDAR sensors which were capable of producing 2,000 to 25,000 pulses per second.
Although primitive compared to today’s instruments, these instruments were robust enough to guarantee the great growth that LiDAR technology was on the way to becoming.

How does LiDAR work?

Modern LiDAR technology is made up of laser sensors that are deployed from the air or via portable units, such as drones. When the lasers point to the mapped area, they emit short light pulses. These light pulses are then reflected on the surrounding objects and are recorded. The time between the output laser pulse and the reflected pulse can be used to deduce the distance at which the object is located as well as several other technical data about the object.

Used in many ways

Since its invention, LiDAR has been used in many revolutionary applications such as autonomous cars, unmanned aerial vehicles, robotics, security, etc. The use of Lidar on autonomous cars undoubtedly marks the greatest technological advance since its invention. Although Lidar technology is not yet optimal for electric cars, it will continue to improve over the years.

LiDAR’s market

The LiDAR market was valued at $ 2.25 billion in 2019 and is expected to reach $ 4.61 billion by 2025. North America is dominating the LiDAR market, due to the growing demand for 3D imaging technology in the United States and Canada. In addition, government agencies are keen on LiDAR technology, which should fuel the market growth. Growing investments by giants like General Motors, Google Inc. and Apple Inc. in autonomous cars offer new opportunities for small LiDAR systems that are versatile and available at low cost.

LiDAR technology is still in its beginnings, but it will continue to surprise us over the years. Who knows, maybe it will allow cars to fly!
