Description

Technical Field

Background Art

[0002] As the level of autonomous driving increases, the requirements for cameras are getting higher and higher; the initial application of on-board cameras was reversing assistance and driving records, mainly to provide images and videos taken by the camera for people to view, and a resolution of hundreds of thousands of pixels can basically meet the requirements. With the expansion of functions and application scenarios, the focus of camera applications has shifted to assisting the system in perceiving the surrounding environment during driving.

[0003] The system has higher and higher requirements for camera resolution, from 300,000 pixels at the beginning to more than 1 million pixels, and now to 2 million pixels. With the further improvement of technology and the promotion of market demand, high-level autonomous driving vehicles in the future are planning to use 8 million-level high-definition pixel cameras to identify and monitor targets at longer distances. The future application trend of high-resolution cameras is unquestionable, and it is the inevitable result of the "dual-wheel drive" of technology and market.

[0004] Currently, the more competitive products on the market are mostly plastic structures with small apertures.
