Research and Application of Bayonet Data Quality Monitoring Method Based on License Plate Recognition
With the growth of car ownership,in order to improve the level of urban road traffic management,more and more cities have in-stalled electronic monitoring equipment on the road,generating massive bayonet data based on license plate recognition,which has been widely applied to different fields.In view of the application of bayonet data and the requirement of data quality and real-time data,a set of indicators to monitor bayonet data quality in real time is discussed.The method first determines the content of the data monitoring of the bayonet equipment,then establishes the calculation index of the data monitoring,and finally gives the application process and example of the method through the actual system.This method has been applied to the data monitoring module of the brain systems in Xuancheng,Shanghai and other cities.With the granularity calculation index of five minutes,the method can detect the bayonet equipment that repor-ted quality problems in time,so as to avoid the subsequent application affected by the bayonet data quality problems.
