What Does iPhone Lidar Do?

The question of what is the use of iPhone lidar is a subject that iPhone users research a lot. It can be answered as Lidar, Light Detection and Ranging. It may be possible to say that it was translated into Turkish as light change and detection. The biggest expectation from Lidar is that it will make even more significant contributions to portrait mode photography. Thanks to this scanner, it is possible to detect both the distances and the depths of the objects in front of the camera very clearly.

There are some thoughts that even better results can be achieved in portrait mode with lidar. It provides the opportunity to determine the depth and distances clearly, and also provides the opportunity to prepare a 3D digital map. Although there is not much difference in Portrait mode on iPhone 12 Pro and Pro Max devices compared to previous models, it is still among the popular features.

How Does iPhone Lidar Work?

In the question of what is the use of iPhone lidar, it was mentioned that it is a scanner that helps to see objects in front of the camera more clearly. How this browser works is also among the things you should know. This camera system, which can scan in three dimensions, contains features that satisfy many users. There are some algorithms required for the lidar scanning system to work. These algorithm types are as follows:

  • Karto
  • Gmapping
  • Hector SLAM
  • Frontier Exploraiton

It has algorithms. These algorithms may vary according to usage areas and places. If tests such as speed and scanning are applied, each algorithm can reveal a high or low performance.

What Does Lidar Do On The Phone?

Before using the feature, you need to know the answer to what is the iPhone lidar in detail. Lidar is known as a type of sensor that can measure with light waves. This scanner is surface-based and processes lasers with wavelengths of 500 nanometers to 600 nanometers.

There may be some differences between wavelengths. The laser beams emitted by the lidar sensor hit the desired objects or surface. Then it goes back to the sensor again. The sensor can measure the distance values ​​of objects according to the return time of these sent laser beams.
