由于最近的社会趋势，强烈需要增强汽车安全性。为了防止交通事故的发生，有必要准确、快速地检测T型交叉口的驶来车辆方向。本文介绍了一种方案，使用一个线性麦克风阵列与四个麦克风估计接近的车辆。我们采用互相关方法实现声源定位，并提出了一种基于插值互相关加权和的方向估计方案。实验表明，该方案提供了良好的性能。
Due to recent trends in society, enhanced car safety is strongly required. To prevent traffic accidents, it is necessary to detect the direction of approaching vehicles in T-intersection accurately and rapidly. This paper describes a scheme that uses a linear microphone array with four microphones to estimate the approaching vehicles. We employ a cross-correlation method to realize sound source localization and propose a direction estimation scheme based on the weighted sum of interpolated cross-correlation. Trials show that the proposed scheme offers good performance.
