Let’s start with a brief introduction: LiDAR is a type of optical technology that uses infrared light to measure distances, localize an object, or create a map of an area. It is one of the most useful and versatile technologies of our time.

It could be used in almost any industry, from smart cars and robots to logistics, construction, forestry, and agriculture. In this guide, we'll deep-dive into the top five most relevant applications of LiDAR technology. If you want a good overview of how LiDAR is mostly being used, you will enjoy this article.


When most people think of the top applications of LiDAR, they think of autonomous cars, but LiDAR has a much wider role to play in the automotive industry, especially with ADAS, or advanced driver assistance systems, which are designed to avoid collisions and create safer situations for road users. Unlike traditional safety measures like the seat belt (passive), ADAS are active safety solutions.

LiDAR technology enables different safety features in ADAS

Examples of LiDAR technology being used for ADAS include lane departure warnings, blind spot detection, and adaptive cruise control.

These modern automotive features may be built directly into vehicles or offered as aftermarket solutions.

Today, according to Canalys research1, an increasing number of vehicles are manufactured with ADAS features built-in: the percentage of cars in use with ADAS feature shall go from 10% in 2020 to 30% in 2030 and 50% in 2050 . These safety measures are required to get the desired results on new vehicle assessment ratings such as EuroNCAP.

Use Case: Commercial Vehicles Safety

A growing number of commercial vehicles, such as trucks, are incorporating LiDAR hardware.

For reference, the global autonomous truck market was valued at USD 846.2 million in 2019 and is expected to grow at a CAGR of 12.8% through 2027, according to Polaris Market Research2.

As one of the most dangerous industries, the world of trucking can massively benefit from LiDAR to improve driver safety, as well as reducing the risk of accidents in locations like construction sites and mines.

Indeed, LiDAR can play a decisive role to anticipate dangerous situations. It can provide essential data to detect, for example, an obstacle or reveal the presence of pedestrians or bicyclists. In these cases, the vehicle can activate the appropriate emergency systems such as automatic braking or lane keeping assistance.

Use Case: Self-Driving Cars

It is becoming more evident that LiDAR sensors will be necessary for Level 4 (High Driving Automation) and Level 5 (Full Driving Automation) autonomous vehicles. As an example, the car manufacturer Mercedes has already planned to integrate it into its top-of-the-range models to assist autonomous driving in its production vehicles.

One reason why LiDAR technology is so important for self-driving cars is that it helps make sure that, even in unknown environments, cars follow the correct route and pose no unnecessary risks to passengers or other road users.

As an example, Outsight supported the creation of fully autonomous shuttle to navigate through a university campus using Outsight’s LiDAR software. The shuttle is capable of detecting moving objects and adjusting its route to avoid them.

There’s lots of scope for this technology to be used further in Smart Cities, and there are already plenty of examples of LiDAR applications for smart infrastructure, including:

Use Case: Intelligent Transportation Systems (ITS)

One of the main applications of LiDAR is ITS. In this case, Outsight’s Augmented LiDAR software can be used, along with LiDAR sensors, to detect and track both vehicles, pedestrians, and other objects in a large surveillance area. The LiDAR system can then be fine-tuned for different applications such as crosswalk safety, over-speed alerts, pedestrian near-misses, and more.

The output is an actionable Dashboard with both real-time alarms triggered by specific events or aggregated data over long periods of time.

Use Case: Anonymous People Tracking

In many ways, airports are like small, enclosed cities of their own, complete with paths, walkways, flows of people, parkings, retail zones, and more.

By combining Edge AI and cloud-based technology, the Augmented LiDAR software carries out enhanced spatio-temporal visual analysis of large spaces like train stations, malls, airports, and more. This allows for precise detection, tracking, and understanding of crowds of people anonymously.

Unlike Camera Face ID, LiDAR data allows for exact detection and tracking of persons and objects, but the resolution of even the best-performing sensors does not allow for recognition, rendering this technology completely anonymous.

Additionally, LiDAR solutions can effective in luggage tracking and preventing los luggage which are likely to cause significant delay.

These functions also apply for train stations, subway, and other modes of public transportation.

Use Case: Spatial Intelligence and Security

Another one of the top applications of LiDAR is for Spatial Business Intelligence.

LiDAR can be used to track and generate actionable metrics about a range of actions and situations throughout an airport environment, including customs and passenger flows through security and other key areas, luggage belt optimization, seat occupancy, and more.

It can also be used for security purposes, generating alerts instantly about unexpected events if some metric reaches a threshold or if a security zone or perimeter is invaded.

Another one of the top five applications of LiDAR is in regard to robotics.

This industry is growing larger and more significant with every passing year, and the rate of development shows no signs of slowing down, with a global growth rate of 15.3% according to Renub Research4.

For those wondering, LiDAR technology is at the core of the smart vehicle and robotics revolutions.

LiDAR software being used in smart vehicles

The main application of LiDAR in terms of robots is to make them safer to work with and be around. Due to the autonomous nature of their operations, these machines require the highest standards of safety technology, and LiDAR can be used to reduce the risks of accidents or injuries involving them.

Use Case: Path Following for Deliveries

Let's imagine that you have an automated guided vehicle, or AGV, inside a warehouse. The vehicle needs to be able to navigate safely and accurately to specific pick-up and delivery locations in the warehouse environment.

LiDAR-enabled path following with Outsight’s relocalization technology can allow the robot to understand not only how it’s moving but also where it is in a reference map - for example, a warehouse map.

Use Case: Teleoperation of Heavy Equipment

One of the most interesting growing trends in terms of applications and uses of LiDAR is to provide pathways for third-person teleoperation of heavy items of equipment and machinery in industries like mining and construction.

LiDAR, when equipped with the right software, provides the unique capability for remote operation in a 3rd person point of view, in real-time, providing high levels of accuracy and reducing accident rates when working with heavy machines.

As an example, in one client case, Outsight helped a power plant operator to identify objects if they go under a crane and sound an alarm to stop operations, gaining real-time awareness

Use Case: Volume Measurement

Another industrial application of LiDAR is to determine the volume of objects, like trucks for instance, as they pass through a gantry.

In this example, an augmented LiDAR software can allow users to leverage LiDAR technology to autonomously detect load volume of each vehicle, saving huge amounts of time and simplifying a formerly complex process.


Finally, the last of the top five applications of LiDAR is mapping.

LiDAR mapping is probably the oldest application of LiDAR, although still a rapidly-growing field of technology, and it's possible to look at thousands of potential and current use cases when it comes to using LiDAR for mapping in industries like forestry, agriculture, city planning, and so on.

Example of Smart Mapping use for forestry applications

LiDAR mapping involves the use of laser scanning systems and advanced SLAM algorithms to precisely measure and map out a space with accurate georeferencing, forming a precise 3D representation of the target area.

LiDAR maps are unique in that they provide absolute positional accuracy, and it's possible to map entire cities in this way. Here are some example use cases:

Use Case: High-Density 3D Mapping

Thanks to the high-grade technology of modern ALB devices, it's possible to make high-density 3D maps in no time at all.

Entire cities or sections of land can be mapped in 3D with stunning levels of precision, and these maps can be used by anyone from city planners to forestry companies. For reference, one of Outsight clients used our software’s mapping feature to localize all street lamps from a certain region in a map.

Another use of LiDAR mapping is for railways and trains. Long-range and medium-range LiDAR detection devices can be used to map out the spaces around railway tracks, and it's even possible to carry out vegetation monitoring along rail routes. All of this can be utilized to make trains safer, smarter, and more efficient.

LiDAR: Technology with Endless Application Potential

Thanks to LiDAR software, now LiDAR can be applied to almost endless use cases.

From making industrial environments safer to helping with forest management and paving the way for the future of safe, autonomous cars, there are no limits to what can be accomplished with this technology.

Almost anything that moves or requires some sort of movement monitoring or measurement can be improved and optimized with the aid of LiDAR.
