Development of a Complex for Supporting Small Citizens Using a Free License

As the basis of the project, the urgent problem was chosen, the movement of people with limited mobility in an urban environment where the geography of the area is constantly changing. The urgency of the problem is expressed by the lack of mass (modern) devices for helping visually impaired (invisible) citizens, and is also clearly expressed by the active position of the state itself and the implementation of the "Accessible Environment" program. According to the results of the analysis of existing solutions, an independent solution is proposed, built on a device with open source software, which will maximize the cost and availability of the device, as well as change its functionality. As the basis of the solution, the RaspberryPi hardware platform is currently proposed on which software running using the OpenCV open-source computer vision library will work.
