<p>Hi Zheng and Srdjan,</p>
<p><br>
I have the same issue with calculation of transformation from quaternion to euler angles using andre-gaschler.com/rotationconverter website.</p>
<p><br>
The values pano_pos_x, pano_pos_y nad pano_pos_z represent the x, y and z coordinate of "center" of the 360 panorama image.</p>
<p><br>
The pano_ori_w, pano_ori_x, pano_ori_y and pano_ori_z represent the orientation of the panoramas in quaternions (w, x, y, z).</p>
<p>I have no idea how to enter the data into the rotation converter to get the correct output. Every time I try to carry conversation out I get erroneous result.</p>
<p><br>
I am attaching a graphic that shows the difference between a panorama and a point cloud</p>
<p><br>
 Best Regards,<br>
Jakub</p>
