Based on this part:
<joint name="camera_joint" type="fixed">
<parent link="base_link"/>
<child link="camera_link"/>
<origin xyz="-0.032 0 0.172" rpy="0 0 0"/>
</joint>
and the screenshot you have taken, I would say the transform may be more like this:
<joint name="camera_joint" type="fixed">
<parent link="base_link"/>
<child link="camera_link"/>
<origin xyz="-0.032 0 0.3" rpy="0 -0.15 0"/>
</joint>
