select a second region which is clear under a low-bright environment from the low-bright image,

combine the first region and the second region to generate a target image, and

extract the vehicle information from the target image.

4. The smart roadside unit according to claim 1 , further comprising:

a first shielding layer covering at least part of the high-bright camera assembly and

a second shielding layer covering at least part of the low-bright camera assembly.

5. The smart roadside unit according to claim 4 , wherein the first shielding layer does not cover camera lenses and heat dissipation components of the high-bright camera assembly; and

the second shielding layer does not cover camera lenses and heat dissipation components of the low-bright camera assembly.

6. The smart roadside unit according to claim 1 , further comprising:

a first radar, and

a second radar, wherein a detection distance of the first radar is greater than a detection distance of the second radar.

7. The smart roadside unit according to claim 6 , wherein the first radar is disposed relatively higher than the second radar in a vertical direction.

8. The smart roadside unit according to claim 6 , wherein the first radar and the second radar are both laser radars.

9. The smart roadside unit according to claim 1 , further comprising:

an antenna, wherein a distance between the antenna and the camera assembly is greater than a preset distance.

10. The smart roadside unit according to claim 1 , further comprising:

a traffic light controlled by the controller according to extracted vehicle information.

11. A method for processing information by a smart roadside unit mounted on a roadway, comprising:

capturing a high-bright image by a high-bright camera assembly and capturing a low-bright image by a low-bright camera assembly, wherein the high-bright image and the low-bright image are acquired at the same time, the high-bright camera assembly and the low-bright camera assembly have a substantially same shooting view and the high-bright camera assembly has a lower ISO sensitivity than the low-bright camera assembly;

extracting vehicle information from the high-bright image and the low-bright image.

12. The method according to claim 11 , wherein extracting vehicle information from the high-bright image and the low-bright image comprises:

selecting a first region which is clear under a high-bright environment from the high-bright image,

selecting a second region which is clear under a low-bright environment from the low-bright image,

combining the image of the high-bright region and the image of the low-bright region to generate a target image, and

extracting the vehicle information from the target image.

13. The method according to claim 11 , wherein a first shielding layer is provided to cover at least part of the high-bright camera assembly; and

a second shielding layer is provided to cover at least part of the low-bright camera assembly.

14. The method according to claim 13 , wherein the first shielding layer does not cover camera lenses and heat dissipation components of the high-bright camera assembly; and

the second shielding layer does not cover camera lenses and heat dissipation components of the low-bright camera assembly.
