<div dir="ltr"><div><div>Hello,<br><br></div>does anyone know how to do the inverse bundler transform?<br></div>This is waht is in the manual (<a href="http://www.cs.cornell.edu/~snavely/bundler/bundler-v0.3-manual.html">http://www.cs.cornell.edu/~snavely/bundler/bundler-v0.3-manual.html</a>) :<br><br><pre><b>P</b> = <b>R</b> * <b>X</b> + <b>t</b> (conversion from world to camera coordinates)
<b>p</b> = -<b>P</b> / <b>P</b>.z (perspective division)
<b>p</b>' = <i>f</i> * r(<b>p</b>) * <b>p</b> (conversion to pixel coordinates)<br><br><br></pre><pre>This explains how to transform a world point X to camera coordinates. <br></pre><pre>But how do I do the inverse transformation? (for instance, how do I get thr x point?.....)<br></pre><br></div>
