Vehicle overrun is one of the main causes of traffic accidents on expressways. A new scheme for over-limit detection of vehicle geometry, research and development of over-limit detection system. The system uses laser ranging as the core technology for size measurement, and the lidar TOF series as the main ranging equipment, combined with the measurement equipment and data of other overload and over-limit subsystems, which can complete the length, width and Dynamic detection of cargo height.
The field test shows that the technical scheme can quickly and accurately measure the geometric dimensions of heavy trucks on highways, and has high application value. The high-speed non-stop over-limit and overload radar detection system is a most advanced detection tool that is widely used in the world to control vehicle over-limit and overload. The system can realize some core application functions of pre-inspection such as vehicle length, width and height detection, vehicle weighing, vehicle type recognition, license plate recognition, video monitoring, and alarm prompt. It also supports different levels of requirements including: on-site overrun detection, remote overrun monitoring, information summary, and statistical analysis.
XD-TOF series laser scanners use the profile measurement function to measure the highest and widest values of passing vehicles to avoid vehicles exceeding the prescribed height and width.
