When studying different fast-moving processes, high-speed video recording is now widely used. The main deterrent for its further distribution remains the high cost of the necessary equipment. Herewith modern mobile devices (including smartphones) are constantly improved, some models are supplied with video cameras with high recording speed - 1000 frames/s and higher. In the paper the possibility of creating a measuring system based on one of the modern smartphone models to analyze the parameters of object motion is studied. The block diagram of the system is given; a layout of such a system has been created. To verify the workability of the developed model of the system, a software and hardware facility was developed to imitate the motion of an object on the Arduino Uno platform with an engine and a carriage moving along the guides. Graphs of changing the coordinates and speed of the object obtained using the program Tracker 5.1.5 are shown. A theoretical estimate of the error in determining the speed of an object using the implemented model of the system is performed. In addition, the estimation of the range of object speeds that can be measured using the developed system, as well as the range of permissible object movements was performed. The results of the performed experiments prove the possibility of creating a measuring system on the basis of the considered model of the smartphone to assess the speed of moving small objects with certain limitations. At the same time, to create a full-fledged measuring system that does not require additional processing of the received resulting video image on a PC and is capable of calculating the necessary results immediately after the end of the measurement process, it is necessary to develop our own software, which is advisable to do using the existing free libraries.
