<div></div>
<p><span style="font-size:20px;"><strong>前提条件</strong></span></p>
<p>本指南需要以下设备：</p>
<ul>
<li>
<p>一台 Raspberry Pi 5</p>
</li>
<li>
<p>一个 Raspberry Pi AI 套件，其中包括</p>
</li>
</ul>
<p> 一个 M.2 HAT+</p>
<p> 一个预装的 Hailo-8L AI 模块</p>
<ul>
<li>
<p>一个 64 位 Raspberry Pi OS Bookworm 安装包</p>
</li>
<li>
<p>任何 Raspberry Pi 官方摄像头（如摄像头模块 3 或高质量摄像头）</p>
</li>
</ul>
<div></div>

<p><span style="font-size:20px;"><strong>硬件设置</strong></span></p>
<p>1. 按照安装 Raspberry Pi 摄像头的说明，将摄像头安装到 Raspberry Pi 5 板上。您可以跳过将 Raspberry Pi 重新连接到电源的步骤，因为您需要断开 Raspberry Pi 的电源才能进行下一步。</p>

<p>4. 安装使用 AI 套件所需的依赖项。在终端窗口运行以下命令</p>
<pre data-widget="codeSnippet">
<code class="hljs"><code>$ sudo apt install hailo-all</code>nbsp;sudo apt install hailo-all</code></pre>
<p>这将安装以下依赖项：</p>
<ul>
<li>
<p>Hailo 内核设备驱动程序和固件</p>
</li>
<li>
<p>HailoRT 中间件软件</p>
</li>
<li>
<p>Hailo Tappas 核心后处理库</p>
</li>
<li>
<p>rpicam-apps Hailo 后处理软件演示阶段</p>
</li>
</ul>
<p>5. 最后，使用 sudo reboot 重启树莓派，使这些设置生效。</p>
<p>6. 为确保一切运行正常，请运行以下命令：</p>
<pre data-widget="codeSnippet">
<code class="hljs"><code>$ hailortcli fw-control identify</code>nbsp;hailortcli fw-control identify</code></pre>
<p>如果您看到类似下面的输出，说明您已经成功安装了 AI 工具包及其软件依赖项：</p>
<pre data-widget="codeSnippet">
<code class="hljs">Executing on device: 0000:01:00.0

<p>7. 为确保摄像机正常运行，请运行以下命令：</p>
<pre data-widget="codeSnippet">
<code class="hljs"><code>$ rpicam-hello -t 10s</code>nbsp;rpicam-hello -t 10s</code></pre>
<p>这将启动摄像机并显示十秒钟的预览窗口。确认一切安装正确后，就可以运行一些演示了。</p>
