AI Technical Summary
Technical Problem
Existing automotive optical lenses perform poorly in low-light conditions, making it difficult to meet the high pixel and high resolution requirements of advanced driver assistance systems.
Method used
It employs an eight-lens structure, a combination of specific optical power and surface shape, including the pairing of negative and positive optical power lenses, corrects aberrations through cemented lens combinations, and optimizes image quality using apertures and filters.
Benefits of technology
It improves the imaging quality of the optical lens, reduces aberrations, and achieves the effects of large aperture, long focal length, low distortion, and high pixel count.
