How LiDAR Works

For some people, the term LiDAR was unknown until Apple launched iPhone 12, it’s not like the term was familiar before except for technical heads. The sudden implementation of the feature on the iPhone makes people curious about LiDAR and how does it work. It might possible now that we will get the same feature in upcoming Android phones too.

In this article, we’ve managed to provide you an explanatory post that will help you to understand what LiDAR is and how does it work. So are you curious to know about the new technologies? We assume as yes because you’re here to know the same. Without wasting much of your time, let’s get started.

How LiDAR Works

What is LiDAR?

LiDAR is capitalized and stands for “light detection and ranging”. It’s a method that is working on light to detect the distance between the LiDAR sensor and the particular object. This is also used in planes. LiDAR sensors consist and used in a variety of forms like LiDAR laser, LiDAR scanner, and also used in GPS unit. Likewise, aerial LiDAR is another advanced device that helps to cope with angle, speed, and craft.

How LiDAR Works?

Let’s start with the basics so that you can understand them easily. A laser transmits a beam of light which then reflects back on the scanner, the data gets contextualized through readings from the GPS unit, which analyzes the position of the LiDAR detector.

This whole process takes some time for the signal to transmit from the laser to the LiDAR scanner, multiplies with tremendous speed similar to the speed of light. This light gets divided into two due to it has to transmit from the scanner to the object and back, so the distance traveled is twice the actual distance bouncing back from the scanner to the object or plane.

LiDAR Applications

There are various applications of LiDAR depending on its uses. They’re as follows:

  1. Now, the latest iPhone 12 is based on LiDAR enabled feature to use the Measure app to calculate the height of the object or person.
  2. Making digital models is possible using LiDAR.
  3. AI (artificial intelligence) also uses LiDAR for a specific purpose.
  4. AR (augmented reality) also uses LiDAR devices.
  5. Some tiny uses like Instagram and Snapchat filters, AR games are some LiDAR applications.
  6. LiDAR is also used to collect data by helicopters, airplanes, and even satellites.
  7. It is also used in organizations like NOAA (National Ecological Observatory Network) in analyzing or making topographical maps for educational purposes like in biology, whether science, earth, construction, disaster assistance, map areas underwater, and even under vegetation.

Looking at the development and progress of LiDAR technology, it can be used widely in the future.
