AI Technical Summary
In existing technologies, when determining the matching relationship between license plate numbers and mobile phone numbers, it is difficult to determine the matching time period, resulting in low matching accuracy or omission of mobile phone numbers, especially when the license plate number and mobile phone number appear only once.
By employing cross-correlation analysis, a license plate number stream and a mobile phone number stream are constructed. The time offset at the maximum value is calculated using the cross-correlation function, which accurately determines the matching relationship between the license plate number and the mobile phone number. This method is suitable for scenarios where the license plate number and the mobile phone number appear only once.
There is no need to manually set the matching time period; the system automatically determines the optimal matching time, improving matching accuracy and data utilization, and is suitable for various scenarios.
