<p>不知道为什么我们专业看起来与计算机八竿子打不着，竟然要学<code>opencv</code>，那就来记录一下吧！</p>
|
|
<h1 id="ubuntu-篇">Ubuntu 篇</h1>
|
|
<p><code>Ubuntu</code>因为有完善的包管理体系，所以配环境相对简单。</p>
|
|
先安装vscode，当然也可以不安装，只是个编辑器；

到这里下载deb格式的软件包，然后dpkg安装即可。可以安装这些扩展：

<p>接下来安装编译器</p>

<p>然后就可以了。</p>

<h1 id="windows-篇">Windows 篇</h1>
|

Windows 下需要安装Visual Studio，比较简单，官网下载安装就行。选择使用C++桌面开发就行。
|
|
下载opencv，在下边网站下载Windows安装包，
|
|
<a class="hexo-link-card" href="https://opencv.org/releases/" target="_blank" rel="external nofollow noopener noreferrer">
|
|
<span class="hexo-link-card__icon" aria-hidden="true">O</span>

<span class="hexo-link-card__body">
|
|
<strong>opencv</strong>
|
|
<span>opencv · opencv.org</span>
|
|
</span>
|
|
</a>
|
|
下载后是一个自解压包，解压路径设置成自己想要的路径，
|
|
把安装路径添加到系统环境变量中，例如D:\Opencv\opencv\build\x64\vc16\bin
|
|
然后应该就没问题了。 </div> <section class="post-copyright-card" aria-label="文章版权信息"> <div class="post-copyright-mark" aria-hidden="true"> <span>CC</span> </div> <div class="post-copyright-main"> <h2>配置opencv</h2> <a class="post-copyright-link" href="/posts/6e3332b/">/posts/6e3332b/</a> <dl class="post-copyright-meta"> <div> <dt>作者</dt> <dd>biss</dd> </div> <div> <dt>发布于</dt> <dd><time datetime="2026-03-14T11:48:36.000Z">2026/03/14</time></dd> </div> <div> <dt>许可协议</dt> <dd><a href="https://creativecommons.org/licenses/by-nc-sa/4.0/" target="_blank" rel="noreferrer">CC BY-NC-SA 4.0</a></dd> </div> </dl> </div> <div class="post-copyright-footer"> <div class="post-copyright-tags" aria-label="文章标签"> <a href="/tags/opencv/">opencv</a> </div> <div class="post-copyright-actions" aria-label="文章操作"> <button class="post-copyright-action is-primary post-share-button" type="button" data-share-title="配置opencv" data-share-url="https://blog.biss.click/posts/6e3332b/" title="分享文章"> <svg aria-hidden="true" viewBox="0 0 24 24"> <path d="M4 12v7a1 1 0 0 0 1 1h14a1 1 0 0 0 1-1v-7"></path> <path d="M12 16V4"></path> <path d="m7 9 5-5 5 5"></path> </svg> <span>分享</span> </button> <a class="post-copyright-action" href="/rss.xml" title="订阅 RSS"> <svg aria-hidden="true" viewBox="0 0 24 24"> <path d="M5 5a14 14 0 0 1 14 14"></path> <path d="M5 11a8 8 0 0 1 8 8"></path> <path d="M6 18h.01"></path> </svg> <span>订阅</span> </a> <a class="post-copyright-action" href="/about/" title="打赏作者"> <svg aria-hidden="true" viewBox="0 0 24 24"> <path d="M7 8h10"></path> <path d="M8 8V5h8v3"></path> <path d="M6 8h12l-1.5 11h-9L6 8Z"></path> <path d="M10 12h4"></path> </svg> <span>打赏</span> </a> <a class="post-copyright-icon" href="https://twitter.com/intent/tweet?url=https%3A%2F%2Fblog.biss.click%2Fposts%2F6e3332b%2F&text=%E9%85%8D%E7%BD%AEopencv" target="_blank" rel="noreferrer" title="分享到 X"> <span aria-hidden="true">x</span> </a> <a class="post-copyright-icon" href="https://service.weibo.com/share/share.php?url=https%3A%2F%2Fblog.biss.click%2Fposts%2F6e3332b%2F&title=%E9%85%8D%E7%BD%AEopencv" target="_blank" rel="noreferrer" title="分享到微博"> <span aria-hidden="true">微</span> </a> </div> </div> </section> <script>
