Problems solved by technology

[0002] With the development of technology, vehicles in our country will realize assisted driving or unmanned driving in the future, and real-time monitoring of the health status of highway pavement is a basic condition that must be met. The condition of highway pavement is complex, involving the number of different lanes, and the number of vehicles passing by road congestion is a common phenomenon, and the spilled objects are also uncertain in time and space. However, the current conventional video sensors are greatly affected by the weather and cannot meet this demand.
