Discover 7 Key LiDAR Applications in Modern Industries Test - 3

Apple's latest Pro and Pro Max series features a LiDAR scanner, allowing night mode portraits and a faster autofocus in low light. The LiDAR scanner on your Apple device not only helps you take sharper pictures but lets you enjoy helpful augmented reality apps and fun games.

For most consumers, this is their first experience with LiDAR technology. But light detection and ranging has been around for more than 60 years. Hughes Aircraft Company built the first LiDAR prototype in 1961. One of the earliest LiDAR applications was by the United States space program, which used the technology for remote sensing to map the moon’s topography during the 1971 Apollo 15 mission.

Today, LiDAR is more down to earth, with an expanding range of LiDAR applications in computer vision and automation. It’s commonly used for object detection in industries like agriculture and utilities—especially to inspect power lines, pinpoint crops for fertilization, detect fruits, estimate and monitor forest canopy structures, identify urine patches in pastures, and assist with pruning fruit trees using high-resolution LiDAR data.

What is LiDAR?

LiDAR, or light detection and ranging, is an active remote sensing technology that uses light in the form of a pulsed laser to measure distance.

Here's what makes LiDAR special:

1. Active technology: Unlike cameras that rely on ambient light, LiDAR systems generate their own laser light using laser pulses, enabling accurate data collection in any lighting condition, including complete darkness. This makes LiDAR applications ideal for real-time and low-light environments.
2. 3-D object detection: It doesn't just measure distance, it captures the entire shape and size of objects, making it ideal for use cases like self-driving cars or robot navigation. In Vision AI, this feature greatly benefits object detection and image segmentation CV tasks.
3. Speed and accuracy: Compared to radar, LiDAR provides much faster and more precise measurements, allowing for real-time applications.

What is LiDAR used for?

LiDAR allows for visibility through dense environments, such as forest canopies. It can create high-resolution digital elevation models with vertical accuracy of up to 1 centimeter. A LiDAR device has several components: a laser scanner, a GPS, and an Inertial Navigation System (INS). The equipment typically mounts onto a mobile vehicle, such as a drone, UAV, or automobile.

Types of LiDAR

Functionally, LiDAR systems are either airborne or terrestrial. Here’s a brief look at each.

Airborne LiDAR

Airborne LiDAR is placed on a drone or helicopter and is helpful for applications that require a bird’s eye view of a vast area. Here, two types of standard LiDAR. The first, topographic, uses a near-infrared laser to map land areas. The second, bathymetric, uses a green water-penetrating light to map underwater terrain.

Terrestrial LiDAR

Terrestrial LiDAR works on the ground and is either mobile or static. Mobile LiDAR systems mount on moving platforms such as autonomous vehicle AI applications to identify objects in the driving environment.

Unlike mobile, static LiDAR systems are installed on stationary structures such as tripods—this type of LiDAR is prevalent in archeology, surveying, mining, and engineering.

LiDAR data is accurate, fast, and beneficial for any location where the structure and shape of objects must be determined.

7 interesting LiDAR applications in the real world 

LiDAR is a valuable technology for several industries, from autonomous vehicles to surveying.

Below are seven interesting applications of LiDAR:

1. Aerial Inspection

   Drones/UAV LiDAR data provides valuable aerial insight into industrial assets that are difficult to inspect, including power lines, civil infrastructure, and other industrial assets, to reduce operational maintenance costs.

2. Precision Agriculture

   LiDAR can help agriculture technology companies pinpoint areas to optimize water, fertilizer, and herbicides or manage pest control to improve crop yield.

3. Forestry and land management

   One of the most impactful LiDAR applications in land management is its ability to measure vertical structures and forest canopy density. Using LiDAR data, organizations can generate terrain models and analyze topography for assessing environmental impact, supporting sustainable forestry practices, and improving fire prevention planning.

4. Survey and mapping

   LiDAR creates accurate maps and digital elevation models for geographic information systems (GIS) to aid civil and commercial surveying and mapping applications.

5. Renewable energy

   LiDAR applications are critical in the renewable energy sector, helping identify optimal conditions for solar and wind energy development. By capturing high-resolution LiDAR data, operators can determine ideal solar panel positioning and calculate wind direction and speed for accurate turbine placement. This use of laser scanning improves site selection and supports the automation of energy infrastructure planning.

6. Robotics

   LiDAR applications in robotics enable systems to equip robots with advanced mapping and navigation capabilities. Using 3D LiDAR and point cloud data, autonomous systems can accurately measure distances between the robot and surrounding objects, allowing for real-time decision-making in dynamic environments.

7. Autonomous Vehicles

   For self-driving vehicle applications, LiDAR provides a longer-range alternative to still image and video cameras, which aren’t as effective in poor atmospheric conditions like rain and fog. Vehicles fitted with LiDAR systems collect data such as road markings, traffic signs, pedestrians, road obstructions, and other vehicles.

LiDAR data labeling for computer vision

💡To be useful for computer vision, and more specifically, supervised machine learning, LiDAR data must be accurately labeled, which is a big job that can be difficult to scale.

The challenge for AI developers is transforming massive, raw data into structured datasets that can be used to train machine learning models. This process often involves extensive data acquisition, followed by hours of data labeling to prepare the information for algorithms that enable machines to interpret and understand the visual world through LiDAR mapping, 3D models, and other sensor-driven inputs.
