TRAFFIC CAMERA DIAGNOSTICS VIA TEST TARGETS
First Claim
1. A method for traffic camera diagnostics via strategic use of at least one moving test target associated with at least one test vehicle, comprising:
- positioning said at least one moving test target in a field of view of a traffic camera to diagnose said traffic camera;
detecting a presence of said at least one moving test target by said traffic camera;
extracting features of said at least one moving test target to analyze said extracted features of said at least one moving test target; and
analyzing said extracted features of said at least one moving test target to characterize, monitor, assess, or diagnose said traffic camera.

Abstract
A method, system, and computer-usable tangible storage device for traffic camera diagnostics via strategic use of moving test targets are disclosed. The disclosed embodiments can comprise four modules: Moving test target management module, Moving test target detection and identification module, Image/video feature extraction module, and Sensor characterization and diagnostics module. A first test vehicle can travel periodically through traffic camera(s) of interest. The traffic camera(s) would then identify these test vehicles via matching of license plate numbers and then identify test targets in video frames through pattern matching or barcode reading. The identified test targets are then analyzed to extract image and video features that can be used for sensor characterization, sensor health assessment, and sensor diagnostics. The disclosed embodiments provide for a non-traffic-stop (i.e., non-traffic-interruption) traffic camera diagnostics.
