<h1>2022 年 TI 杯大学生电子设计竞赛声源定位跟踪系统（E题）</h1>
<h1>新栏目来袭：声源主题专场</h1>
<n-ellipsis expand-trigger="click" line-clamp="1" :tooltip="false">
本题是设计制作一个声源定位跟踪系统，能够实时显示及指示声源的位置，当声源移动时能够用激光笔动态跟踪声源。
是的，这题我们可以重新拿出 K210 了，下面是一些小伙伴在比赛后的结果展示。
嘿 SIPEED 又来玩点不一样的事情辣！开设首个精选专场栏目，本次万众期待的主题是【声源系列-声源定位】快来与我们一起重新认识声源定位吧！

<h2>声源定位是什么？</h2>
</n-ellipsis>
<p>指利用多个麦克风在环境不同位置点对声信号进行测量，由于声信号到达各麦克风的时间有不同程度的延迟，利用算法对测量到的声信号进行处理。<br>由此获得声源点相对于麦克风的到达方向（包括方位角、俯仰角）和距离等。</p>

<br><img src="https://wiki.sipeed.com/hardware/assets/spmod/spmod_micarray/spmod_micarray.png" style="max-width:240px; max-height:240px;" alt="" />
<p>麦克风阵列模块是 Sipeed 基于 MSM261S4030H0 数字麦克风芯片设计的，模块声音识别灵敏度、信噪比高。<br>由沿板的六个麦克风和一个中心的麦克风组成，阵列板上的 12 颗 LED 可以用来可视化识别声源方位，基于 GCC-PHAT 算法实现声源定位、语音识别、波束成形等需求场合。</p>
<n-ellipsis expand-trigger="click" line-clamp="1" :tooltip="false">
<h2>其次，麦克风阵列是需搭配开发板（K210）才能实现声源定位</h2>
</n-ellipsis>
<br><img src="./static/home/micarray.png" style="max-width:320px; max-height:320px;" alt="" />
<P>当然有实力的小伙伴可以自由发挥创意并实现不一样的麦克风阵列新玩法，萌新的小伙伴们可以参考我们例程来实现声源应用。
<br>这里为小伙伴们附上了相关的 K210 选型以及上手指南。</p>

<h2>铛 ~ 揭秘声源定位算法：GCC-PHAT</h2>

<br>
<img src="https://wiki.sipeed.com/hardware/assets/spmod/spmod_micarray/MicArray.png" style="max-width:240px; max-height:240px;" alt="" />
<br><p>GCC-PHAT 是一种基于广义互相关函数的时延估计算法，多用于声源定位的应用以及实现。它通过引入一个相位变换加权函数，对互功率谱密度进行调整，从而优化时延估计的性能。<br>广义互相关函数有多种不同的变形，其中广义互相关-相位变换方法（Generalized Cross Correlation PHAse Transformation，GCC-PHAT）方法应用最为广泛。<br>而 GCC-PHAT 方法本身具有一定的抗噪声和抗混响能力。</p>
