C(2025·湖北武汉·高三检测)
Autonomous systems like self-driving cars and robots are becoming more common, and their integration promises to transform industries by increasing efficiency and safety. However, they often fail to see and work well in different environments—like rainy days, low light, or complex backgrounds, because in these cases their sensors are affected. Interestingly, nature may have already shown how to deal with that.
Now, scientists have designed a new vision system for robots, enhancing object detection and recognition. The cat's eye caught their attention due to cats' excellent vision in both light and darkness. During the day, a cat's pupil is a vertical slit-like(垂直狭缝状的)shape that reduces bright unpleasant lights to help focus. At night, the pupil widens to let in more light, with a surface enhancing the cat's vision by reflecting visible light back. Similarly, the new system includes a slit-like opening design that helps block out unnecessary light and single out key objects in bright conditions, and then uses a surface similar to that of cats' eyes to improve visibility in low-light conditions.
Robotic cameras often have difficulty in spotting objects in busy or complex backgrounds, especially with changing lighting. The new design successfully makes background objects blurred. It allows robots to ignore unnecessary details and focus on targets. Scientists also use a brain-like learning network to help the system better identify important objects. The vision system is more energy efficient as it relies on a specialized instrument rather than substantial computer processing.
This groundbreaking technology unlocks exciting possibilities for real-world applications, transforming robotic vision and letting autonomous systems skillfully navigate(有效应对)complex environments and undertake tasks with great accuracy. From search and rescue operations to industrial monitoring, these cutting-edge robotic eyes stand ready to complement or even replace human efforts in a variety of critical scenes.
