It can be understood that the rotating device 10 can perform a coarse adjustment of the shooting angles of the first camera 31 and the second camera 32 synchronously, i.e. a rotation adjustment of a large angle. If the shooting angle of the single-side camera needs to be rotated, for example, a road on one side is straight and a road on the other side is curved, the single-side camera needs to have a function of finely adjusting the shooting angle.

Therefore, on the basis of the rotating device 10, please refer to fig. 4 and also refer to fig. 5 for fine adjustment of the shooting angle of the first camera 31, and fig. 5 is a schematic structural diagram of the first adjusting mechanism 33 in the present application.

Further, the first adjusting mechanism 33 further includes a first vertical adjusting assembly 332, the first vertical adjusting assembly 332 includes a second driving member 3321 and a first vertical rotating gear 3322, which are disposed on the first horizontal adjusting assembly 331, and the second driving member 3321 is connected to the first camera 31 through the first vertical rotating gear 3322, so as to drive the first camera 31 to rotate vertically relative to the housing 20. So set up, can increase first camera 31 at the shooting scope of vertical direction, and can finely tune first camera 31 at the shooting angle of vertical direction, adapt to different shooting demands, make first camera 31 can be through the condition of first perpendicular adjustment assembly 332 control the place ahead and upper and lower both sides. And the first horizontal adjusting component 331 cooperates with the first vertical adjusting component 332 to enable the first camera 31 to shoot a certain position at a fixed point within the shooting range, so as to acquire a specific image.

It is understood that the first horizontal adjustment assembly 331 and the first vertical adjustment assembly 332 can be correspondingly applied to the second camera 32 to increase the horizontal and vertical shooting range of the second camera 32, so that the second camera 32 can shoot a position at a precise fixed point as the first camera 31. That is, in order to fine-tune the shooting angle of the second camera 32, a second horizontal adjustment assembly 341 and a second vertical adjustment assembly 342 may be added to the second camera 32 for horizontal and vertical adjustment.

With the arrangement, the shooting range of the second camera 32 in the transverse direction can be increased, different shooting requirements can be met, and the shooting angle of the second camera 32 in the transverse direction can be finely adjusted on the basis of the rotating device 10.

second adjustment mechanisms

33, 34 are substantially identical in their rotational configurations and functions, except that they are mounted to the housing 20 at spaced intervals for adjusting the photographing angle of the first camera 31 and the photographing angle of the second camera 32, respectively.

Referring to fig. 6, fig. 6 is a schematic structural diagram of the second adjustment mechanism 34 in the present application. It is understood that the first camera 31 and the second camera 32 can perform both the synchronous coarse adjustment of the shooting angle by the rotation device 10 and the fine adjustment of the shooting angle by the first adjustment mechanism 33 and the second adjustment mechanism 34, respectively. In other words, the first camera 31 and the second camera 32 can be quickly coupled to the two shooting areas opposite to each other by the rotating device 10, and can be independently rotated in the respective shooting areas by the first adjusting mechanism 33 and the second adjusting mechanism 34, so as to meet various shooting requirements. For example, when one side of a road is straight and the other side of the road is curved and extended, the rotating device 10 may drive the first camera 31 and the second camera 32 to turn greatly, so as to achieve initial adjustment, so that the first camera 31 faces the straight side of the road, and then the shooting angle of the second camera 32 is finely adjusted by the second adjusting mechanism 34, so that the camera shoots towards the curved and extended side of the road without affecting the shooting angle of the first camera 31, thereby ensuring that both sides of the road can obtain good shooting effect or monitoring effect. It can be understood that the application scope of the present application is not limited to the above examples, and the present application may perform various adaptive adjustments according to different road conditions, which is not described herein again.

The spherical lower shell 22 can avoid obstructing the first adjusting mechanism 33 and the second adjusting mechanism 34 from driving the first camera 31 and the second camera 32 to rotate, so as to ensure the normal shooting of the first camera 31 and the second camera 32. The first window 221 and the second window 222 with the arc-shaped structures can prevent rainwater from being hung on the outer walls of the windows, and the clarity of pictures shot by the first camera 31 and the second camera 32 is improved.

Specifically, in the present embodiment, the lower shell 22 is a spherical cover, and the first window 221 and the second window 222 are both cambered windows. Preferably, in this embodiment, the outer walls of the first window 221 and the second window 222 are further plated with hydrophobic films, so as to further avoid a rainwater wall-hanging phenomenon and improve the shooting quality.

It should be noted that the third window 223 is disposed below the first window 221 and the second window 222, so that the infrared rays can be better irradiated on the shooting area to clearly display the road condition at night; meanwhile, the third window 223 is disposed below the first window 221 and the second window 222, so that the infrared light is prevented from being directly incident on the first window 221 and the second window 222 to affect the normal shooting of the first camera 31 and the second camera 32.

Preferably, in the present embodiment, two infrared lamps are provided, respectively, at two opposite sides of the bottom wall of the lower case 22. Specifically, an infrared lamp is respectively arranged below the first camera 31 and the second camera 32, and the irradiation directions of the two infrared lamps have an included angle, so that the infrared irradiation range can be greatly increased.

Furthermore, in order to enable the first camera 31 and the second camera 32 to capture clearer images, in the present embodiment, the first camera 31 and the second camera 32 are preferably zoom cameras, and thus, the first camera 31 and the second camera 32 can realize remote identification through zoom focusing, and can be used for monitoring illegal parking conditions of vehicles on the road surface, identifying license plate numbers of vehicles, and the like.
