Patent attributes
The present disclosure provides a lens module, a camera, and a driver assistant system. From an object side to an image side, the lens module sequentially includes a first lens with a negative refractive power, a second lens with a negative refractive power, a third lens with a positive refractive power, a stop, a fourth lens with a positive refractive power, a fifth lens with a negative refractive power, a sixth lens with a positive refractive power, and a filter. The fifth lens and the fourth lens constitute a bonding lens group. The second lens, the third lens, the fourth lens, and the fifth lens are glass spherical lenses, and the first lens and the sixth lens are both glass aspherical lenses. The lens module significantly increases the distortion in a small FOV to meet the special algorithm requirements of an in-vehicle system.
