What is LiDAR?

LiDAR – Light Detection and Ranging – is a technology that targets an object with a laser and measures the time that passes until the reflected light returns to the receiver. This means LiDAR sensors are capable of generating a 3D or 2D image with spatial and depth data for detecting, measuring, localizing and tracking objects.

LiDAR technology has revolutionized automation in countless industries, from automotive to logistics and warehousing to aerospace. LiDAR sensors with a real-time detection range of up to 360° are used to detect obstacles in industrial environments such as factories and warehouses. In transport vehicles, for instance, the systems detect distances and prevent collisions with people, objects or other vehicles. LiDAR sensors installed in robot arms or manned forklift trucks provide greater efficiency, accuracy, and safety by simplifying and optimizing handling, transport, loading and unloading, and material storage.

SICK pioneered LiDAR technology back in the 1980s and has since revolutionized its application in industry over the past decades. The company’s innovative sensor technology is helping to shape the world of tomorrow today.

2D LiDAR sensors

The subset of LiDAR sensors that operate in two dimensions all use a single plane of lasers to capture X and Y dimensions. This measurement data enables accurate navigation and detection of objects, both indoors and outdoors, regardless of the ambient light. For a wide range of applications, particularly in the industrial setting, this form of laser scanner provides an economical ranging solution.

3D LiDAR sensors

3D LiDAR sensors add another dimension to the scanning plane, thus delivering measurement data in a total of three dimensions. The collected measurement data digitally maps out the real world, enabling the detection of objects in three-dimensional space, even under extreme weather conditions and in undefined environments. 3D LiDAR sensors are the ideal solution for many applications, even under difficult conditions, from people counting at airports to automatic vehicle guidance, precise localization and collision avoidance, for instance in ports, logistics centers and factories.

SICK 2D LiDAR sensors cover a wide range of indoor and outdoor applications, even in harsh weather conditions. In ports, they prevent collisions with cranes and containers. In logistics, they are used on mobile robots for palletizing and depalletizing processes, for collision avoidance by detecting hanging objects in factories, or obstacles and people in the travel path of autonomous delivery robots. On roads they are used to monitor speed and height violations, while in airports they efficiently monitor boarding gates and security door systems. In countless buildings they detect unauthorized access, open swing doors and activate escalators when a person approaches.

SICK 3D LiDAR sensors are widely used for collision avoidance and driver assistance come rain, hail, snow or shine. In ports, airports, mines and production facilities, on the road, in buildings and on farms, these robust and versatile sensors assist navigation and collect valuable data as they perform a myriad of tasks such as protecting ships from collisions with bridges, locks or other ships; monitoring goods transports by ensuring efficient loading processes on belts, stockpiles, ship loaders and silos; safely maneuvering mining vehicles across rugged terrain; identifying vacant parking spaces in car parks, or counting people entering or leaving an area.
