<spanid="id1"></span><h1>auto-boundary<aclass="headerlink"href="#auto-boundary"title="Permalink to this headline"></a></h1>
<p>Automatically set a boundary using camera shot locations to limit the area of the reconstruction. This can help remove far away background artifacts (sky, background landscapes, etc.). See also --boundary. Default: <codeclass="docutils literal notranslate"><spanclass="pre">False</span></code></p>
<h2>What Is Auto-Boundary?<aclass="headerlink"href="#what-is-auto-boundary"title="Permalink to this headline"></a></h2>
<p><codeclass="docutils literal notranslate"><spanclass="pre">--auto-boundary</span></code> is a process that seeks to limit the boundaries of the reconstruction based upon a K-Means filtered Convex Hull buffered by 20x the mean GSD of the dataset.</p>

<h2>When Is Auto-Boundary Helpful?<aclass="headerlink"href="#when-is-auto-boundary-helpful"title="Permalink to this headline"></a></h2>
<p><codeclass="docutils literal notranslate"><spanclass="pre">--auto-boundary</span></code> is appropriate to use on any dataset where one might possibly consider limiting the area of reconstruction due to the presence of sky or far-away background that they would not normally consider part of the desired reconstruction.</p>
<p><codeclass="docutils literal notranslate"><spanclass="pre">--auto-boundary</span></code> does not have a meaningful impact on nadir (or near-nadir) imagery without sky/background, making it superfluous, but safe, to include.</p>
<p>In other words, if you would consider masking the image, <codeclass="docutils literal notranslate"><spanclass="pre">--auto-boundary</span></code> is likely a good choice.</p>
</section>
<sectionid="why-would-one-use-auto-boundary">
<h2>Why would one use auto-boundary?<aclass="headerlink"href="#why-would-one-use-auto-boundary"title="Permalink to this headline"></a></h2>
<p>Auto-Boundary is most helpful in preventing the reconstruction area from growing needlessly large when things like sky, clouds, or far-away features like treelines get included in the reconstruction.</p>
<p>By preventing the boundaries of the reconstruction from growing needlessly large, Out-Of-Memory errors become far less likely, and one will likely see a decrease in processing time due to the smaller area being reconstructed.</p>
