AI Technical Summary
Technical Problem
Existing automotive OMS cameras have low resolution, making it difficult to meet the needs of autonomous driving.
Method used
By rationally allocating the effective focal length, refractive index, and on-axis distance of each lens, a 5-megapixel automotive OMS lens was designed. It uses a combination of meniscus negative, meniscus positive, biconvex positive, biconcave negative, and meniscus positive lenses to form a cemented lens group, and uses aspherical lenses to improve image quality.
Benefits of technology
It achieves a high resolution of five megapixels, high lens imaging quality, small size, low cost, and can be used normally in a temperature range of -40℃ to 95℃, meeting the needs of autonomous driving.

Abstract
The utility model relates to the technical field of lenses, and discloses a vehicle-mounted OMS lens, which comprises a first lens, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens which are sequentially arranged from an object space to an image space along an optical axis, under the condition that retroflexion caused by aspheric coefficients is not considered, the first lens is a meniscus concave negative lens, the second lens is a meniscus convex positive lens, the third lens is a biconvex positive lens, the fourth lens is a biconcave negative lens, the fifth lens is a biconvex positive lens, and the sixth lens is a meniscus convex positive lens. Wherein the fourth lens and the fifth lens form a balsaming lens group, and the second lens, the fourth lens, the fifth lens and the sixth lens are aspheric lenses. According to the vehicle-mounted OMS lens provided by the utility model, an optical system realizes the resolution of five million pixels by reasonably distributing the effective focal length and the refractive index of each lens, the axial distance between the lenses and the like.
