After the nationwide cancellation of provincial toll stations on highways, the operation mode of "one network" on highways has been entered, greatly improving the efficiency of highway traffic. However, the fast and efficient mode of transportation has also brought huge challenges to toll auditing: after the station is removed, the amount of fees charged per trip increases sharply, and the high profits brought by evading toll fees drive the emergence of various means of fare evasion.

With the gradual popularization of ETC toll collection on highways and the increasing discount on tolls, more and more drivers and passengers choose to apply for ETC as a means of transportation and payment. However, some drivers have resorted to brainwashing by registering for ETC through banks, exploiting the loophole of information asymmetry and incompleteness that results in discrepancies between actual vehicle models and billing models to achieve the purpose of "big car and small label" fare evasion. In addition, the non-standard behavior of some ETC handling personnel has led to frequent occurrences of "big car and small label" phenomena, resulting in a significant loss of tolls.


In order to adapt to the new situation of fee management and achieve balanced development in personnel, cost, efficiency, management, and other aspects, traditional single technological means can no longer fully meet the increasing needs of users. A new generation of laser+video dual recognition product - laser vision integrated vehicle recognition instrument - has emerged, which combines multiple technological means.


As a high-precision vehicle recognition device, the "Laser Vision Integrated Vehicle Recognition Instrument" adopts an integrated design, based on machine vision information technology and multi-dimensional vehicle feature information extraction technology, to capture and intelligently recognize vehicles entering the lane in real time, obtain complete images of vehicle license plates/bodies/parking spaces, as well as feature data such as vehicle types, wheels/axles, etc., and complete the collection of vehicle information. In terms of vehicle type and license plate accuracy, the accuracy of vehicle type recognition and license plate recognition both reach over 99%, achieving accurate recognition of vehicle types and license plates.


The vehicle recognition equipment only needs to be installed on one side of the toll island to be used, with high detection efficiency. After the vehicle passes through the detection area normally, there are detection results, which can be used for real-time detection or post inspection; The system is easy to upgrade and can adapt to new car models in the future, without the need for hardware upgrades。
