An early warning system for height limit based on multi-sensor information fusion

With the continuous development of social economy, infrastructure such as highways and bridges continues to develop, and overloaded vehicles are repeatedly prohibited. Therefore, many places have set up "height limit gantry frames" at the entrances of bridges and overpasses, artificially limiting the types and sizes of vehicles, increasing the safety of bridge structures and roads, but also bringing many safety hazards. In recent years, accidents of ultra-high vehicles colliding with "height limit gantry" have occurred frequently, causing serious personnel and property losses. Therefore, it is particularly important to identify and prompt super high vehicles in advance to avoid such accidents. To address such issues, a height limit information early warning system based on V2X multi-sensor information fusion has been developed. Using LiDAR to identify the height of vehicles, using cameras to identify vehicle license plates, and then conducting information fusion, combined with the above information, warning dangerous vehicles through various channels such as V2X or roadside LED screens.
