[0070] Please refer to Figure 1. The present invention is a method for processing license plate data based on traffic information extraction and calculation. The method consists of the following four steps:
[0071] Step 1: Build a vehicle license plate recognition database IIX in the computer of the background processing center,
[0072] Step 2: Preliminarily match the vehicle license plate data of the starting point O and the end point D specified by the user, and establish the vehicle travel time detection database IX in the background processing center computer.
[0073] Step 3: Construct the user-specified path information particles, run the program through the computer to eliminate the ambiguous path noise in the vehicle travel time detection database IX, and obtain the vehicle travel time database X of the user-specified path.
[0074] Step 4: Construct travel time information particles, and run the program through the computer to eliminate the travel time noise in the vehi...
