With the continuous increase in road mileage and the continuous improvement of road networks in my country, the traffic volume has also increased significantly, and the management of road traffic is facing tremendous pressure. Smart transportation is an effective way to help reduce management pressure. Smart transportation refers to the use of intelligent means to perceive, identify, calculate and publish results of the three subjects of human, vehicle and road traffic in traffic scenarios, aiming to serve transportation participants and infrastructure managers.

[0003] At present, there are a large number of cylindrical cameras used to shoot traffic violations in traffic scenes. The images obtained are used to collect license plate information, driver status, line crossing conditions, etc. However, in fact, the images captured have a wider range of applications. For example, a cylindrical camera can be used to shoot road images, and machine vision technology can be further used to identify road cracks, potholes and other road diseases, as well as road conditions such as spilled objects and road water. Compared with objects such as vehicles, license plates, and traffic markings, road diseases and road conditions are smaller targets and more sensitive to shooting range, shooting angle, and external light. This requires adjusting the horizontal direction and pitch angle of the camera according to needs. Especially for small-sized targets that need to enlarge the focal length to be identified, the image range becomes smaller after zooming. If you want to cover the entire road surface with solid lines, you need to adjust the horizontal direction and pitch angle of the camera.
