In the ITS (Intelligent Transport Systems), detecting vehicles running on a road is one of the most important tasks. To detect vehicles running on a road with low traffic volume, we are developing a vehicle detector using stereo microphones. By calculating the time difference of arrival of vehicle sound signals on two microphones with cross-correlation, this system successfully detects vehicles with high accuracy at a low cost. However the accuracy of the detector is affected by environmental noise such as rain noise. This paper presents a de-noising method which can be used on the acoustic vehicle detector. We capture sound signals when no vehicle is passing and add the absolute values of frequency components of the sound signals to reduce the influence of noise in cross-correlation. To demonstrate the effectiveness of the proposed method, we conducted experimental evaluation in Kyushu University campus. The experimental evaluation demonstrated that the proposed method reduced the number of undetected vehicles and improved vehicle detection accuracy in raining and heavy raining conditions by 4 and 13 points, respectively. |
