Abstract
The paper is devoted to an examintaion of a possibilty for usage of LiDAR integrated into modern smartphones (on the example of iPhone 12 Pro) to indoor measurements. Most often this type of measurements is carried out for inventory or state cadastral registration. For this the mentioned device was used to collect data of two complex shaped rooms. Afterwards the data were compared with two point clouds created by ground-based LiDAR providing the accuracy of the claimed works and accepted as standard measurement data. The comparison was provided both for point clouds (using CloudCompare) and for room plans made using these clouds. For the first room the average square error of measurement deviation was 5–6 cm, for the second is 2–3 cm. The deviation less than 5 cm between point clouds created by smartphone and those of LiDAR refers to 78% in the first room and 32% in the second room. The results illustrate that the current technology is not appropriate for an indoor measurement accuracy which is defined as 1 cm in Russia.
