1. A system for error detection, comprising:
- a non-transitory memory device for storing computer-readable program code; and
a processor in communication with the memory device, the processor being operative with the computer-readable program code to perform operations comprisingpreparing a training set based on at least a first set of recognition data associated with a first sensor, wherein the first set of recognition data comprises records that store recognized identifiers associated with vehicles,training a confusion matrix based on the training set,detecting at least one erroneous record in a second set of recognition data associated with the first sensor wherein the second set of recognition data comprises records that store recognized identifiers associated with the vehicles, anddetermining correction of the erroneous record by comparing similarity with records associated with other sensors using the trained confusion matrix.

Abstract
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.

10. A computer-implemented method of error detection, comprising:
-
receiving a first set of recognition data associated with a sensor and a second set of recognition data associated with one or more other sensors; detecting, based on a predetermined rule, at least one erroneous record in the first set of recognition data; determining a correction of a first recognized identifier in the erroneous record by searching the second set of recognition data for a matching record with a second recognized identifier substantially similar to the first recognized identifier; and generating a report that presents the detected erroneous record and the determined correction. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)

20. A non-transitory computer-readable medium having stored thereon program code, the program code executable by a computer to perform steps comprising:
-
receiving a first set of recognition data associated with a sensor and a second set of recognition data associated with one or more other sensors; detecting, based on a predetermined rule, at least one erroneous record in the first set of recognition data; determining a correction of a first recognized identifier in the erroneous record by searching the second set of recognition data for a matching record with a second recognized identifier substantially similar to the first recognized identifier; and generating a report that presents the detected erroneous record and the determined correction.
