摘要：
The utility model relates to the field of orientation systems and can be used in orientation systems for blind and visually impaired people. The technical task of the utility model is the development of a device for orientation in space of people with visual impairment, which provides accurate recognition of objects in the surrounding space. The technical result of the utility model is to expand the functionality of the device due to accurate perception of the shape and size of objects located directly in front of a person with visual impairment in the direction of movement, as well as to the right and left of him. The device for assisting people with visual impairments contains a tube with a handle at the top. The tube contains a microcontroller and a pattern recognition system, a tactile screen. In the front part of the handle, on the left and right, there are video cameras directed perpendicular to the direction of movement of the blind person, connected to the pattern recognition system. The tube has an accelerometer connected to a microcontroller. An electric drive and an electric drive control unit are installed in the handle, and the input of the electric drive control unit is connected to the controller output, and the electric drive output is connected to the main video camera, an alarm unit connected to the microcontroller output. An accelerometer measures the tilt of a visually impaired device relative to the Earth's surface. The signals from the accelerometer are fed to the microcontroller, where, after processing, a signal is generated for restructuring the position relative to the Earth's surface of the main video camera, which is transmitted through the electric drive control unit to an electric drive connected to the video camera. Images taken from additional cameras are compared with vertical objects. The results of comparing images of surrounding objects and images stored in the database are used to form in the microcontroller, together with the si
