The invention is suitable for the technical field of optical imaging, and provides a wide-angle unmanned aerial vehicle lens, which comprises a first lens, a second lens, a third lens and a fourth lens which are sequentially arranged from an object plane to an image plane along an optical axis, the first lens is a meniscus lens with negative diopter, and the convex surface faces the object surface; the second lens is a meniscus lens with positive diopter, and the convex surface of the second lens faces the object surface; the double surfaces of the third lens are even-order aspheric lenses; the fourth lens is a biconvex positive diopter lens; the wide-angle unmanned aerial vehicle lens provided by the invention is simple in structure, light in weight and low in cost, and can be used for imaging at infinity; when the method is applied to aerial photography of the unmanned aerial vehicle, the higher and higher practical requirement of a user for the imaging quality of aerial photography can be met, and the long endurance performance of the unmanned aerial vehicle can be effectively guaranteed.

    本发明适用于光学成像技术领域,提供了一种广角无人机镜头,所述广角无人机镜头包括:沿光轴从物面到像面依次设置的第一透镜、第二透镜、第三透镜和第四透镜;所述第一透镜为弯月型负屈光度透镜,凸面朝向物面;所述第二透镜为弯月型正屈光度透镜,凸面朝向物面;所述第三透镜的双面为偶次非球面透镜;所述第四透镜为双凸正屈光度透镜;本发明提供的广角无人机镜头,不仅结构简单、重量轻、成本低,而且能在无穷远处成像;应用在无人机航拍时,既可以满足用户对航拍的成像质量要求越来越高的现实需求,也可有效保证无人机具有较长的续航性能。
