Embodiment
[0038] A video number plate data quality analysis method according to an embodiment, takes a single number plate recognition device as an object, and identifies abnormal data by analyzing data integrity, data flow rationality, and data time rationality, and recognizes number plate Early warning of equipment failure, timely judgment of number plate recognition data quality, early warning of faulty equipment, providing high-quality data for traffic control, and ensuring stable operation of the system.
[0039] A video number plate data quality analysis method, based on the online status of the video number plate recognition equipment to analyze the integrity of the equipment data collection, and further based on the video number plate historical data and vehicle inspection device data quality and GPS data information for data rationality Analyze and automatically warn of equipment failures. Such as figure 1 ,details as follows:
[0040] S1. Analyze the integrity of the data co...

A video license plate data quality analysis method is provided. The integrity of device data collection is analyzed based on the on-line condition of a video license plate recognition device. The rationality of data is further analyzed based on video license plate historical data, vehicle detector device data quality and GPS data information, and the device fault is automatically early-warned. Thevideo license plate data quality analysis method constructs a data integrity-flow rationality-time rationality data quality testing system; based on the on-line condition of the license plate identification device, the flow data analysis and the time difference analysis, the data collected by the license plate identification device is analyzed and detected, and the abnormal condition of the device is judged according to the abnormal data and the automatic warning is made, so that the manager can effectively grasp the health status of the monitoring device and timely carry out maintenance management on the abnormal device.
Description
technical field [0001] The invention relates to a method for analyzing the quality of video number plate data. Background technique [0002] "Number plate recognition" uses the dynamic video of the vehicle to automatically identify the vehicle license plate number, which is the principle of the main collection of electronic police, smart bayonet and other equipment. At present, number plate recognition equipment is widely used in urban traffic control, but affected by uncertain factors such as equipment working status, network transmission, road traffic conditions, surrounding environment, etc., number plate recognition equipment may have data quality problems, such as data loss, License plate recognition abnormalities, time data drift, etc., and data quality problems will directly affect the reliability and stability of electronic police, smart checkpoints, ETC, and self-service parking detection systems, and have adverse effects on traffic control and law enforcement. The...
