The appearance of Lidar in the iPhone 12 Pro and 12 Pro Max did not particularly surprise anyone, but caused a few questions. The main thing is why he is generally needed. No, Apple's audience for the most part turned out to be quite advanced and perfectly understood that the Ludar serves in the most different goals, but why he needed in the iPhone, it was quite difficult to guess. Moreover, Apple itself has in no hurry to offer some scenarios of use by placing this duty to developers. Not to say that those somehow became particularly actively at the exploitation of a new sensor, but something was still invented.
Explore Mars and drive a car? What is the lidar in iPhone 12 Pro
Lidar performs measurements about five times more accurate than conventional cameras that are installed in modern smartphones, including the iPhone photo modules. Such a conclusion was made by the developers of the Canvas application to create three-dimensional models of premises. They compared the performance of the lidar, which are equipped with the iPhone 12 Pro and 12 Pro Max, with a manual tape measure and a building rangefinder, and came to the conclusion that the smartphone sensor gives an error at the level of 1-2% against about 5-6% from ordinary cameras.

Lidar in the new iPad Pro turned out to be even useless than we thought
Due to the high accuracy of scanning space, the lidar can be actively used in 3D modeling and architecture. CANVAS developer experience This proves it is better. The application uses the smartphone rangefinder to determine all the volumetric objects, partitions, furniture items, etc., and on the basis of the data, it builds a three-dimensional model. It can be useful to interior designers, engineers or, say, furniture makers who make a bed or a cabinet strictly under the specified dimensions.
Why do you need Lidar in iPhone
However, it is clear that modeling or something similar is the sphere is quite narrowly specialized. That is, each owner of the iPhone 12 Pro clearly will not use Lidar for this purpose. But where it will be - so it is in the photo. Due to the fact that Ladar is like a photographed object, it can be used to increase the clarity of portrait pictures made under conditions of insufficient lighting. Ludar allows you to highlight the object of shooting on a general background, even if its silhouette merges with the environment.
The developers have shown that Lidar is capable of iPad Pro
Look at the photo above. On a woman wearing a black coat, and she herself stands against the background of the river in almost the absence of natural lighting. However, for Lidar, it does not represent special difficulties to separate the photographed from the background. It simply radiates a beam of light, he stupns on the first object that in this case is a positive woman, forms a three-dimensional silhouette and returns back. All this takes the fraction of a second, which makes the impression that no additional processes occur. However, the result due to this turns out to be much better.
