<p dir="auto">I would like to use different AprilTag families than the old 36h11 family. How much work would it be to run a different family through the modalAI architecture over ROS packages? Ideally, I would like to change the voxl-tag-detector so it can use the custom48h12 family. How would one approach this problem?</p>
<p dir="auto">Thank you.</p>

<p dir="auto">We’re currently in the process of updating the <code>voxl-tag-detector</code> to support additional AprilTag families beyond just the <code>36h11</code>.</p>
<p dir="auto">If you’d like to try this yourself in the meantime, the following line in <code>main.cpp</code> creates the detector for the <code>36h11</code> family: <a href="https://gitlab.com/voxl-public/voxl-sdk/services/voxl-tag-detector/-/blob/master/server/main.cpp?ref_type=heads#L615" rel="nofollow ugc">here</a></p>
<p dir="auto">To add support for the <code>tagCustom48h12</code> family, you can:</p>
<p dir="auto">Add the include:</p>
<pre><code>#include &lt;tagCustom48h12.h&gt;
</code></pre>
<p dir="auto">Replace the detector creation line with:</p>
<pre><code>tf = tagCustom48h12_create();
</code></pre>
<p dir="auto">Please note that this change may affect the current functionality, you’ll likely need to make additional modifications in <code>main.cpp</code> to ensure it builds and runs correctly.<br />
As mentioned, we’re actively working on making this a much smoother process in the future. But if you’d like to get started now, the above steps should point you in the right direction.</p>
