What is LiDAR Scanner?

LiDAR stands for Light Detection and Ranging. The concept of LiDAR has been around since the 1960s. LiDAR scanner basically helps you scan and map your environment by shooting laser beams and then timing how quickly the light return to its source. A processor is then used to make an accurate picture out of the scanned information.

LiDAR tech is used in augmented reality apps as it lets the developers create an accurate model of both the object and the space. Most recently, LiDAR has been seen in self-driving cars.

LiDAR scanner is a system that is used by apps on your iPhone 12 Pro. That being the reason, you cannot use the LiDAR scanner directly. However, you can see the improvements in the apps you are using.

Apple’s Measure App is a primary beneficiary of the LiDAR scanner. This app lets you scan the entire environment, and after that, you can tap specific points to calculate distance, length, areas, etc. Using the LiDAR scanner, the Measure app has become faster and more accurate as the system is capable of producing delicate details.

Besides, iPhone 12 Pro takes comparatively less time to scan the environment in Measure before you can start taking the readings. This enhanced speed is the result of the LiDAR scanner system reading and interpreting its surroundings more accurately than the standard camera.

Another place where the LiDAR scanner is used is in the Camera app of your iPhone. It helps your camera perform better in low light. If we go by the reports of Apple, the camera is now capable of autofocus six times faster, even when light is not appropriate.

You can also take Night mode portraits using the iPhone’s low-light compensation mode. As the scanner is better at spotting the difference between foreground and background, it produces better-contrasted images at night or in dark areas.
