<p dir="auto">I am setting up a drone with VOXL2 to perform obstacle avoidance using both front and rear stereo inputs. So far, everything seems to work reasonably for the front camera pairs, but as for obstacle distance readings from the rear stereo, an obstacle seem to be always present in the back of the drone. I think that the reason behind this detection is related to my current design of the drone which partially occludes the FOVs of the stereo pair (see pictures below). Could you confirm if this could be the issue? Is there a parameter in the config files that could allow me to discard point clouds that are too close (i.e. in my case the chassis of the drone)?</p>
<p dir="auto">Thanks a lot in advance for your reply!<br />

Which autopilot are you using?</p>

<p dir="auto">It depends which SDK you are using, if you are using SDK 0.9.5 you have to setup the parameters in voxl-vision-px4. There you can both enable the VOA (<code>en_voa: true</code>) and select the camera with which you want to perform the VOA <code>voa_inputs</code>. Then, if you want to send the VOA data with the telemetry to the ground station you can also set ```<br />
en_send_voa_to_qgc: true</p>
<pre><code></code></pre>

can you share how did you enable voa on voxl2 platform?<br />
