Real-Time 3D Mapping in Complex Environments for Visually Impaired People

Abstract

In today’s age and time, there are many technologies designed to help humans deal with any kind of disability that they might be facing. Out of many disabilities, the one that usually stands out the most is vision. Vision is the ability of a living creature to see, and humans also face this disability on a huge scale. Many ways are constantly developed to help us face this issue such as having guide dogs or having another person guide us through our journey around our environment. Some of these ways can be very time-consuming and expensive depending on the method used. We are engineers who need to address such issues with innovative ideas and methods. One way to deal with blindness is to develop a smart stick that can guide the user to their destination through many features it possesses. We design, develop, and test a real-time 3D mapping system intended to help visually impaired people navigate complicated interior situations. The device combines a Lidar sensor and ultrasonic sensors with an ESP32 microprocessor to deliver precise, real-time positional awareness and obstacle detection. This project’s major purpose is to improve the mobility and safety of visually impaired users by providing a portable, cost-effective, and dependable navigation tool. Real-time 3D mapping in complex environments is designed to assist visually impaired individuals in navigating their surroundings. The research addresses the challenges faced by visually impaired users which include obstacle detection and environmental understanding. The proposed system produces accurate representations of complex environments by combining many sensors like Lidar and ultrasonic sensors with 3D mapping algorithms. This research is an important development in visually impaired technology that might enhance the lives of people with visual impairments worldwide.
