Tactile Paving Recognition Method Based on Improved YOLOv7

Tactile paving is a professional road facility to ensure the safe travel of people with visual impairment. However, there are many problems with tactile paving travel in practice. For one, some tactile paving is seriously damaged, and the other is the accumulation of obstacles. How to help visually impaired people recognize and locate obstacles in tactile paving is a problem worth studying. In this paper, image recognition technology is used to recognize the tactile paving pictures with obstacles, and an attention mechanism is used to optimize samples to improve recognition accuracy.
