Abstract

The invention provides a method for repairing missing paths based on machine learning and license plate recognition data, by searching for possible noise sources from the acquired license plate recognition data, screening and cleaning them, extracting the travel trajectory of the vehicle, and then analyzing the travel trajectory according to the itinerary The abnormal value of the time is further processed to ensure the validity and rationality of the travel trajectory data; and the effective features in the travel trajectory data are extracted to train an effective machine learning model. For the missing paths of large-scale points and license plate recognition data, Estimate the information of vehicles passing through each intersection to form a complete travel chain. The method of the invention is based on the basic data items of the urban video license plate recognition data, and solves the problem that the vehicle travel trajectory extracted based on the lack of a path is caused by missing or wrongly captured points in the license plate recognition data.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, and more specifically, to a method for repairing missing paths based on machine learning and license plate recognition data. Background technique [0002] With the development momentum of the intelligent transportation industry and the rise of big data storage and data mining technology, based on the rapid development of artificial intelligence machine learning, deep learning and other technologies, based on basic traffic data, such as automatic number plate recognition data (Automatic Number Plate Recognition, ANPR), Global Positioning System data (Global Positioning System, GPS) data, coil data, mobile phone signaling and other data collection technology upgrades, can obtain more and more effective travel trajectory related information, for the extraction of traffic travel trajectory data To lay a foundation, through the obtained accurate travel trajectory information, it is ...
