The light shield is a common photographic accessory mounted in front of a photographic lens, a digital camera, and a video camera to shield harmful light. In general, a lens cover for a general camera lens is screwed to a camera housing in front of the lens. The light shield is divided into a cylindrical light shield, a petal-shaped light shield and a square light shield according to the shape. As shown in fig. 1, fig. 1 is a schematic structural view of a lens hood for a camera in the related art. Specifically, the light shielding cover 10a may include a cylindrical cover body 11a, a plurality of petal-shaped protrusions 112a are provided at one end of the cover body 11a, and a screw or snap structure for connecting a lens may be provided at the other end.

Whereas for an autonomous vehicle, an onboard camera is one of the necessary sensing devices in an autonomous system. The vehicle-mounted camera can be used for collecting two-dimensional color information around a vehicle in a real environment and is an important data source for judging surrounding objects by an automatic driving system. In addition, the vehicle-mounted camera can provide important functions such as multi-mode, high-precision time synchronization, exposure control, color lamp color correction and the like, so that basic hardware guarantee is provided for an automatic driving vision system. Therefore, the in-vehicle camera is known as "autopilot", and is one of important sensor devices in the field of advanced driving assistance systems (Advanced Driver Assistance System (ADAS), also called autopilot systems) and automobile autopilots. The vehicle-mounted camera mainly realizes the acquisition function of image information through the vehicle-mounted lens and the image sensor, can realize 360-degree visual perception, overcomes the defect of the radar in object recognition, and is the sensor closest to human vision.

However, during the shooting and/or photographing process, light outside the angle of view may enter the vehicle lens, and then may be reflected by internal structural components of the vehicle lens, thereby forming glare or ghosting. Especially for an automatic driving vehicle, the glare and the ghost directly influence the judgment of a vehicle-mounted imaging system, so that the driving safety is influenced. Therefore, it is also necessary for the in-vehicle camera to install a hood for the in-vehicle lens.

Also, since the vehicle-mounted camera is also required to install a wiper and to meet aesthetic demands, the vehicle-mounted camera is also required to install a light-transmitting plate such as a flat glass mirror. Thus, the lens hood 10a structure of the general camera as shown in fig. 1 is not suitable for the lens of the in-vehicle camera. Therefore, it is necessary to provide a shading element suitable for a vehicle-mounted camera, so as to effectively avoid the influence of glare and ghosting on the judgment of a vehicle-mounted imaging system, and further ensure the driving safety of automatic driving.

Specifically, the lens protection cover 50 may also have a substantially cylindrical hollow columnar body, for example, to fit the shape of the connection portion 12 of the camera body 10. Further, the lens protection cover 50 may include a protection cover base 52 that can be fitted over one side of the camera body 10, for example, the connection portion 12, the protection cover base 52 having an end 54 remote from the camera body 10. Wherein the protective cover base 52 can be used to protect the lens 20.

In some embodiments, as shown in fig. 3, the light shielding film 40 is perpendicular to the direction of the axis L of the protective cover base 52.

Further, the inner diameter of the protective cover base 52 is substantially greater than or slightly equal to the outer diameter of the connection portion 12, so that the protective cover base 52 can be tightly fitted over the connection portion 12 of the camera body 10.

In some embodiments, the outer diameter of the boot base 52 is smaller than the outer diameter of the end 54. And, the end 54 is provided with a third opening 540 at an edge remote from the protective cover base 52, the third opening 540 having an inner diameter smaller than the inner diameter of the end 54 and larger than the inner diameter of the protective cover base 52.

Alternatively, the third opening 540 may be substantially circular in shape.

As shown in fig. 3, the light-transmitting plate 30 is embedded in the third opening 540, and a gap is formed between the lens base 224 and the light-transmitting plate 30, so that light in the angle of view can enter the lens 20.

Alternatively, the light-transmitting plate 30 may be a flat glass sheet, which may be generally circularly shaped to conform to the shape of the third opening 540 of the end 54.

In some embodiments, the light shielding film 40 is attached to a side of the light-transmitting plate 30 facing the lens 20, and the light shielding film 40 attached to the light-transmitting plate 30 may form a notch 410. Wherein the notch 410 may also be configured to allow only light rays within the field angle of the lens 20 to pass therethrough and into the lens 20. Specifically, the light in the angle of view can pass through the light-transmitting plate 30 and enter the lens 20 through the notch 410, and the stray light and/or harmful light outside the angle of view can be blocked by the light shielding film 40 on the light-transmitting plate 30, so that the stray light and/or harmful light is prevented from entering the lens 20, and further, the formation of glare and ghost images is effectively avoided, and the light shielding effect is realized.

In other embodiments, the light shielding film 40 may be attached to a side of the light-transmitting plate 30 away from the lens 20, and the light shielding film 40 attached to the light-transmitting plate 30 may also form a notch 410, which has the same function as when the light shielding film 40 is attached to a side of the light-transmitting plate 30 facing the lens 20, and will not be described in detail herein.

Alternatively, the notch 410 is in the shape of a closed arc. In some embodiments, the notch 410 may include four concave arcs, and the four concave arcs collectively enclose a closed notch. Further, the notch 410 is concave in one circular arc toward the other circular arc opposite thereto.

In other embodiments, the notches 410 may be arranged in a four-pointed star-like configuration.

It will be appreciated that although the notch 410 is shown in fig. 2 as including four concave circular arcs, this is not required, and the number of concave circular arcs may be set according to the specific application, as long as the light shielding film 40 can be made to realize a light shielding effect such that the optical distortion of the lens becomes small.

In some embodiments, the protective cover substrate 52 and the end 54 of the lens protective cover 50, the light-transmitting plate 30 and the light-shielding film 40 attached to one side of the light-transmitting plate 30 may form a light-shielding member, the light-shielding member may be applied to a camera, and light outside the view angle of the camera lens may pass through the light-transmitting plate 30 and enter the lens 20 through the notch 410 of the light-shielding film 40, while stray light and/or harmful light outside the view angle may be blocked by the light-shielding film 40 on the light-transmitting plate 30, thereby preventing stray light and/or harmful light from entering the lens 20, and further effectively avoiding formation of glare and ghost images, and realizing the light-shielding effect.

In other embodiments, the light shielding member and the vehicle-mounted camera in the present application may be provided separately. Specifically, the in-vehicle camera may include a camera body 10, a lens 20 connected with the camera body 10, and other functional elements. That is, in the application of the vehicle, the in-vehicle camera 100 may include an element that realizes a photographing function. On the basis, in order to effectively avoid glare and ghosting, the shading piece in the application can be sleeved on the vehicle-mounted camera.

In order to clearly illustrate the working principle of the in-vehicle camera 100 in the present application, embodiments in the present application are further described with reference to table 1 and fig. 4 to 10, specifically as follows:

referring to fig. 4 to 6, fig. 4 is a schematic view of normal imaging of an object, fig. 5 is a schematic view of pincushion distortion, and fig. 6 is a schematic view of barrel distortion.

Distortion is one of the important parameters in optical systems and is one of the important factors limiting the accuracy of optical measurements. Specifically, distortion refers to the degree of Distortion of an image of an object by an Optical system relative to the object itself, and Optical Distortion (Optical-disturbance) refers to the degree of Distortion calculated in Optical theory.

As shown in fig. 5, pincushion distortion (Pincushion Distortion), also called pincushion distortion, refers to a phenomenon in which an imaging screen is "contracted" toward the middle by an optical system. Pincushion distortion is common in tele imaging. The distorting mirror imaging for making people thin and high belongs to pillow type distortion.

As shown in fig. 6, barrel distortion (Barrel Distortion) is also called barrel distortion, and is a distortion phenomenon in which an image formed by an optical system is in a barrel expansion shape. Barrel distortion is common in photographic lens imaging, particularly wide angle lens imaging. Distorting a person is a more visual example of barrel distortion.

The lens 20 in the embodiment of the present application may be used to refract light incident on the lens 20. Wherein the optical distortion of the lens 20 is negative and the optical distortion of the lens 20 satisfies a predetermined curve.

Alternatively, the lens 20 in the embodiment of the present application is a wide-angle lens, and the optical distortion thereof is barrel distortion.

Referring to fig. 7 and table 1, fig. 7 is a schematic diagram of calculating optical distortion, and table 1 is a table of optical distortion parameters of a lens.

The calculation formula of the optical distortion is as follows:

table 1 optical distortion parameters table of lens

As shown in table 1, Y angel in table 1 is the maximum angle of view; real height in table 1 is the actual image height, which characterizes the distance of the pixel to the center point and corresponds to Y as described above. Ref height in Table 1 is the ideal image height and corresponds to Y0 as described above. The dispersion in table 1 is an optical Distortion value and corresponds to D0 as described above.

According to the optical distortion parameter table of the lens in table 1 and the length and width values of the camera sensor, the angle of view that can be achieved by each line of the onboard camera 100 in the vertical direction can be calculated, namely: vertical angle of view, and angle of view achievable per line in the horizontal direction, namely: horizontal angle of view.

Based on the calculation results of the vertical view angle and the horizontal view angle of the camera, the shape and the size of the light shielding film 40 in the embodiment of the present application can be calculated, as shown in fig. 8 and 9, fig. 8 shows a schematic structural diagram of the light shielding film attached to the light transmitting plate in one embodiment of the present application, and fig. 9 shows a schematic structural diagram of another viewing angle of the vehicle-mounted camera in one embodiment of the present application.

Referring to fig. 8, as shown in fig. 8, the light shielding film 40 may be attached to a side of the light transmitting plate 30 facing the lens 20. Further, according to the design requirement of the field angle of the camera, a notch 410 with a closed arc shape is formed on the light shielding film 40, and the whole light shielding film 40 attached to the side of the light transmitting plate 30 facing the lens 20 forms a special shape with a concave arc on the light transmitting plate 30. Therefore, in some embodiments, the light shielding film 40 in the embodiments of the present application may also be referred to as a profile light shielding film 40. Specifically, the profiled shape of the notch 410 may be set according to the angle of view of the camera.

Alternatively, as shown in FIG. 8, the notch 410 is in the shape of a closed arc and is generally concave. Further, the light shielding film 40 may further include a first light shielding portion 41, a second light shielding portion 42, a third light shielding portion 43, and a fourth light shielding portion 44. The shape of the first light shielding portion 41 may be substantially convex, i.e.: the arc of the first light shielding portion 41 toward the opposite third light shielding portion 43 is convex. Similarly, the second light shielding portion 42, the third light shielding portion 43, and the fourth light shielding portion 44 are substantially the same shape as the first light shielding portion 41. Thus, the convex arc shape of the first light shielding portion 41, the second light shielding portion 42, the third light shielding portion 43, and the fourth light shielding portion 44 is adapted to the closed arc shape of the notch 410 and is substantially concave. Specifically, the first light shielding portion 41, the second light shielding portion 42, the third light shielding portion 43, and the fourth light shielding portion 44 are all disposed to extend from the edge of the light-transmitting plate 30 toward the notch 410.

Further, the light-transmitting plate 30 with the special-shaped light-shielding film 40 attached thereto is then mounted in the third opening 540 of the lens protection cover 50, so that a light-shielding film 40 suitable for the in-vehicle camera 100 is obtained, as shown in fig. 9.

Further, referring to fig. 10, fig. 10 shows a schematic view of the shading effect of the shading film mounted in the in-vehicle camera in the embodiment shown in fig. 8. As shown in fig. 10, when light outside the angle of view passes through the light-transmitting plate 30 and enters the lens 20, the light-shielding film 40 is attached to the side of the light-transmitting plate 30 facing the lens 20, so that stray light and/or harmful light such as non-imaging and scattered light is blocked by the light-shielding film 40, and the stray light and/or harmful light is prevented from entering the lens 20, thereby realizing the light-shielding effect.

Further, when designing the shape and size of the light shielding film, the parameters of the field angle may be calculated according to the specific application requirements, and then the design shape and size of the light shielding film 40 in the embodiment of the application may be calculated based on the field angle parameters, and the designed light shielding film 40 is attached to the side of the light transmitting plate 30 facing the lens 20 and is circumferentially arranged on the side of the light transmitting plate 30 facing the lens 20. And according to the design parameters of the view angle of the camera, the light shielding film 40 is provided with a notch 410 in a closed arc shape, so that stray light and/or harmful light are prevented from entering the lens 20, glare and ghost formation are effectively avoided, the optical distortion of the lens 20 is reduced, the truest photo can be effectively taken, and more reliable judgment data is provided for an automatic driving system, so that the driving safety of automatic driving is ensured.

It should be understood that, although fig. 8 illustrates the special-shaped shape of the light shielding film 40 in an embodiment of the present application, this is not necessary, and the special-shaped shape and size of the light shielding film 40 may be designed according to the specific application, as long as the effect of shielding stray light and/or harmful light to prevent stray light and/or harmful light from entering the lens 20 can be achieved, which is not limited in the present application.

In particular, as shown in fig. 11 and 12, the protection assembly 200 may include a mounting seat 21 and a protection cover 23 connected to the mounting seat 21. The mounting base 21 of the protection component 200 is provided with a first through hole 211, wherein the shape of the first through hole 211 is matched with the shape of the camera body 10 of the vehicle-mounted camera 100, so that the camera body 10 can be embedded in the first through hole 211. Alternatively, the first through hole 211 may also have a substantially rectangular shape.

Further, the protection cover 23 of the protection assembly 200 is provided with a second through hole 231, wherein the shape of the second through hole 231 is adapted to the shape of the lens protection cover 50 of the vehicle-mounted camera 100, so that the lens protection cover 50 can be embedded in the second through hole 231. Alternatively, the second through hole 231 may have a substantially cylindrical shape.

Thus, when in installation, the vehicle-mounted camera 100 can sequentially pass through the first through hole 211 and the second through hole 231, so that the light-transmitting plate 30, the light-shielding film 40, the lens 20 and the camera body 10 of the vehicle-mounted camera 100 are embedded in the first through hole 211 of the mounting seat 21 and the second through hole 231 of the protective cover 23, and the signal transmission assembly 60 is arranged on one side of the first through hole 211 away from the protective cover 23. Then, the protection assembly 200 mounted with the in-vehicle camera 100 is mounted on the vehicle body 31 (as shown in fig. 13). Alternatively, the protection assembly 200 mounted with the in-vehicle camera 100 may be mounted at different positions on the vehicle body 31, for example: the positions of the front windshield of the vehicle body 31, the periphery of the vehicle body 31, the top of the vehicle body 31, and the like may be specifically set according to actual application conditions, and are not limited in this application.
