Real-time Adaptive Gray Threshold Measurement In Extracting Traffic Parameters
In order to extract traffic parameters more efficiently,an adaptive gray threshold traffic parameters measurement (AGTTPM) system is built in this paper.In AGTTPM,a novel real-time adaptive gray threshold (RAGT) measurement method is presented to conquer the over sensitivity of vision based method in day and night shadows or illumination environment.RAGT is a method which could highly enhance the detection accuracy by means of adjusting the gray threshold to the surroundings automatically.According the RAGT measurement,the traffic parameters can be obtained in real time and the corresponding errors can also be inhibited obviously.The implementation of system hardware and software is introduced by steps and RAGT is introduced in the part of software design.Experimental results show the improvements in detection precision and real-time performance comparing with traditional static gray threshold method.
