AI Technical Summary

Problems solved by technology

The current license plate recognition equipment is scattered on both sides of the toll station lane, which occupies a large area and has a low integration level. The driver cannot timely and accurately understand the information of the vehicle he is driving from several devices in a short period of time, which prolongs the time for the vehicle to pass through the toll station. It brings a lot of inconvenience to people's travel; at the same time, the license plate recognition device with too low integration cannot provide effective protection, which will easily cause damage to important parts of the license plate recognition device.
