Embodiment Construction

[0042] For a better understanding of the application, various aspects of the application will be described in more detail with reference to the accompanying drawings. It should be understood that these detailed descriptions are descriptions of exemplary embodiments of the application only, and are not intended to limit the scope of the application in any way. Throughout the specification, the same reference numerals refer to the same elements. The expression "and / or" includes any and all combinations of one or more of the associated listed items.

[0043] In the drawings, the thickness, size and shape of lenses have been slightly exaggerated for convenience of illustration. In particular, the shapes of spherical or aspheric surfaces shown in the drawings are shown by way of example. That is, the shape of the spherical surface or the aspheric surface is not limited to the shape of the spherical surface or the aspherical surface shown in the drawings. The drawings are example...

Abstract

The invention provides an automobile front-view lens, which has the advantages of miniaturization, large field angle and higher imaging quality, and is characterized in that a first lens has negativefocal power, the object side surface of the first lens is a convex surface, and the image side surface of the first lens is a concave surface; a second lens has negative focal power, the object side surface is a concave surface, and the image side surface is a convex surface; a third lens has positive focal power, the object side surface of the third lens is a convex surface, and the image side surface is a convex surface; a fourth lens has any one of positive focal power and negative focal power, the object side surface of the fourth lens is any one of a concave surface and a convex surface,and the image side surface of the fourth lens is any one of a convex surface and a concave surface; the fifth lens has any one of positive focal power and negative focal power, the object side surfaceof the fifth lens is any one of a convex surface and a concave surface, and the image side surface of the fifth lens is a convex surface; the sixth lens has positive focal power, the object side surface of the sixth lens is a convex surface, and the image side surface is a concave surface; and the automobile front-view lens meets the condition that FOV is larger than or equal to 140 degrees.

Description

technical field [0001] The invention relates to the technical field of optical imaging, is applicable to the fields of automobile front-view systems and driving assistance, and specifically relates to a car front-view lens. Background technique [0002] With the continuous development of intelligent and safe driving of automobiles, the requirements for active driving or assisted driving imaging lenses continue to increase. Under the requirement of maintaining the high resolution of the lens, the requirements for environmental stability are getting higher and higher, especially when it comes to the driver's active safety front-view lens. [0003] In recent years, the front-view lens is also developing towards a miniaturized design trend. In the process of lens module miniaturization, people also hope that the lens has both higher pixels and field of view, so as to facilitate the acquisition of a wider field of view. scope. The field of view angle of the existing front-view ...
