Patent number: 10839303Abstract: Disclosed herein are system, method, and computer-readable device embodiments for automatically correcting erroneous license plate numbers generated by automatic license plate recognition. An embodiment operates by selecting a set of adjacent license plate recognition (LPR) stations comprising a first LPR station, a second LPR station, and a third LPR station, accessing an error pattern probability matrix for at least the third recognized license plate number accessed in relation to at least one of the first recognized license plate number or the second recognized license plate number differing from the third recognized license plate number, and determining a corrected license plate number based on the error pattern probability matrix. In some embodiments, LPR correction may be accurately realized even when an erroneous license plate numbers are missing characters, such as by visual obstruction from an LPR camera or sensor, or has no characters in common with the real license plate number.Type: GrantFiled: August 21, 2017Date of Patent: November 17, 2020Assignee: SAP SEInventors: Chang Yi, Qiong Luo, Guangji Zhu, Chao Yu, Qiwei Zhang, Yinling Ni

Patent number: 10255514Abstract: Disclosed herein are system, method, and computer program product embodiments for automatically detecting cloned vehicle identifiers. An embodiment operates by determining legitimate trajectory information and illegitimate trajectory information corresponding to vehicular travel in a geographic area, and training a decision model to detect a cloned vehicle identifier based on the legitimate trajectory information and the illegitimate trajectory information. Furthermore, the embodiment identifies vehicles potentially using a cloned vehicle identifier based on the decision model and common driving patterns within the geographic area. In some embodiments, enforcement agents are notified of the vehicles potentially using a cloned vehicle identifier.Type: GrantFiled: August 21, 2017Date of Patent: April 9, 2019Assignee: SAP SEInventors: Chang Yi, Qiong Luo, Guangji Zhu, Chao Yu, Qiwei Zhang, Yinling Ni

Patent number: 10163038Abstract: Described herein is a descriptive framework to facilitate error detection in recognition data. In accordance with one aspect of the framework, at least one erroneous record is detected in a first set of recognition data. The framework may determine a correction of a first recognized identifier in the erroneous record by searching a second set of recognition data for a matching record with a second recognized identifier substantially similar to the first recognized identifier. A report may then be generated to present the detected erroneous record and the determined correction.Type: GrantFiled: December 24, 2015Date of Patent: December 25, 2018Assignee: SAP SEInventors: Ke Wang, Yinling Ni, Ling Chen, Ye Jin, Qiwei Zhang, Jing Liu, Xin Li, Chao Yu

Patent number: 10163339Abstract: Described herein is a framework to monitor traffic congestion. In accordance with one aspect of the framework, the framework receives vehicle data from vehicle data sources located in a region of interest. The framework may determine a sample size and an average speed for an edge of the region of interest based on the vehicle data. Congestion probability may then be determined based on the sample size and average speed. A report may be presented based on the congestion probability.Type: GrantFiled: December 13, 2016Date of Patent: December 25, 2018Assignee: SAP SEInventors: Jing Liu, Qiwei Zhang, Jun Liu, Yinling Ni
