Description

Technical Field

[0001] The present invention relates to the field of optical imaging technology, and in particular to a super fisheye optical system with integrated side ring for auxiliary driving. Background Art

[0002] The earliest applications of vehicle-mounted optical systems were reversing assistance and driving recording. With the expansion of functions and applications, different application scenarios have emerged, such as side view, surround view, electronic rear view, and in-cabin monitoring. Among them, the vehicle-mounted surround view optical system is mainly used for automatic parking, and the vehicle-mounted side view optical system is mainly used for side collision warning and object recognition. The current vehicle-mounted automatic driving system includes 4 side view optical lenses and 4 surround view optical lenses, a total of 8 optical lenses, which can assist the driver in perceiving the surrounding environment, such as the relative position and distance of surrounding obstacles, lane line inspection during driving, etc., effectively avoiding the safety hazards in the blind spots of the car's field of vision during driving, thereby realizing automatic driving of the vehicle. The side view lens is mainly responsible for collision warning and object recognition, generally with an HFOV of 80-100 degrees, and a pixel density that is large in the center and small at the edge; the surround view optical lens is mainly used for automatic parking, generally with an HFOV of 190-200 degrees, and a pixel density that is small in the center and large at the edge; Currently, autonomous driving systems consist of four side-view cameras installed on the vehicle. However, this system does not provide good image quality at edge angles. For safety reasons, a surround-view system must also be equipped with four surround-view cameras. Separate algorithms must be developed for each system, leading to high vehicle hardware and algorithm costs. To address this issue, the present invention provides a super fisheye optical system with integrated side-view and surround-view technology for driver assistance. Summary of the Invention The present invention proposes a super fisheye optical system with integrated side and surround vision for assisted driving, which solves the problems that existing lenses cannot take into account both side and surround vision, have small apertures, low pixels, and poor high and low temperature imaging effects.

[0030] The aspheric coefficient satisfies the following equation:

[0031] Where z is the aspheric sag, c is the aspheric paraxial curvature, the curvature and the radius of curvature are reciprocal relations, y is the lens aperture, k is the conic coefficient, a4 is the 4th-order aspheric coefficient, a6 is the 6th-order aspheric coefficient, a8 is the 8th-order aspheric coefficient, a10 is the 10th-order aspheric coefficient, and a12 is the 12th-order aspheric coefficient.

[0032] Table 2 Aspheric Coefficients

[0033] Table 3 Pixel Densities at Each Field Angle

[0034] Where, for Tables 1 - 3, the effective focal length of the optical system is 1.7 mm, the aperture value FNO is 1.6, the total length of the optical system is 21 mm (the distance from the vertex of the first lens E1 to the image plane IMA), the size of the imaging surface of the optical system is 6.03 mm, and the maximum field angle is 200 degrees. In Table 1, surface represents the surface number of the lens surface, R value and Radius represent the radius of curvature, Thickness represents the thickness, Index represents the refractive index, ABB represents the Abbe number, EFL-E represents the focal length of the lens, INFINITY represents infinity. In Table 2, R1 represents the radius of curvature of the side of the corresponding lens facing the object side, and R2 represents the radius of curvature of the side of the corresponding lens facing the image side. In Table 3, Deg represents the field angle, REAL-IH represents the real image height, REF-IH represents the reference image height, PPD represents the pixel density. It can be seen from Table 3 that the pixel density distributions at each field angle are uniform.

[0035] It should be noted that the mirror numbers 1 and 2 successively represent the two mirrors of the first lens E1 along the light incident direction, the mirror numbers 3 and 4 successively represent the two mirrors of the second lens E2 along the light incident direction, the mirror numbers 5 and 6 successively represent the two mirrors of the third lens E3 along the light incident direction, the mirror numbers 7 and 8 successively represent the two mirrors of the fourth lens E4 along the light incident direction, the mirror numbers 10 and 11 successively represent the two mirrors of the fifth lens E5 along the light incident direction, the mirror number 12 represents the mirror of the sixth lens E6 facing the object side, the mirror number 13 represents the cemented surface of the sixth lens E6 and the seventh lens E7, the mirror number 14 represents the mirror of the seventh lens E7 facing the image side, and the mirror numbers 15 and 16 successively represent the two mirrors of the eighth lens E8 along the light incident direction. In the embodiment of the present invention, from Figure 2 the defocus curve graph, it can be seen that the MTF concentration of the lens is good, which is convenient for focusing. The trends of the defocus curves at different field angles are consistent, and the distance of the central axis of the defocus curve is within 0.008 cycles / mm. From Figure 3 、 Figure 4 it can be seen that the defocus curves at high temperature and low temperature both meet the requirements of high resolution, the change in the focus of the defocus curve is small, and the distance of the central axis of the defocus curves at different field angles corresponding to high temperature and low temperature is also within 0.008 cycles / mm, and the thermal drift effect is stable; Figure 5 is the modulation transfer function (MTF) curve graph in the visible light band, which represents the comprehensive resolution ability of the optical system. In the graph, the horizontal axis represents the spatial frequency, unit: cycles / mm (100 lp / mm), and the vertical axis represents the value of the modulation transfer function (MTF). The value of MTF is used to evaluate the imaging quality of the lens, and the value range is 0-1. It should be particularly pointed out that the optical transfer function is a more accurate, intuitive and common way to evaluate the imaging quality of an optical system. The higher and smoother its curve is, the better the imaging quality of the system is and the stronger the ability to restore the real image is; From Figure 5 it can be seen that in the visible light band when the spatial frequency is 100 lp / mm, the MTF in the imaging area near the center is >0.7, and the imaging quality is good. Figure 6 、 Figure 7 It also shows that the change in MTF resolution at high temperature and low temperature is small; Figure 8 represents the field curvature graph. From Figure 8 it can be known that the field curvature value is controlled between -0.05 mm and 0.05 mm. The smaller the field curvature value is, the better the imaging quality of the lens is; Figure 9 represents the F-THETA distortion graph. The smaller the F-THETA distortion is, the smaller the compression amount of the imaging picture edge is; Figure 10 represents the imaging spot diagram of light with different wavelengths. Figure 10 It shows that the concentration of pixel points of light with different wavelengths is good.
