Hi Pablo, in my quest to visualize the model I go on with a couple of questions if you don't mind.
In the XYZ model an example w 3 cameras can look like in *illustration1 * attached. It is a 2D illustration, disregarding the Y dimension for the moment. * 3 cameras with different Z & X, and different Yaw * The common projection surface is at z=1 (or was it -1?). The red line * XYZ, ypr are independent parameter per Snapshot (= camera position + image) * With configurable projection plane* >My experimental implementation does use "plane yaw" and "plane pitch", >to specify the surface normal of the plane, and the plane is always >tangent to the unit sphere around the "panorama camera". This works very >similar to the yaw and pitch of the input images. For example, a plane >at the nadir would be specified by >plane_pitch=-90. If I get you right, the constraints on these planes are: * They are tangent to the unit sphere around the panoramic camera => - the panoramic camera is positioned in (0,0,0) - sphere radius 1 to the tangent plane - The radius/plane normal has the Te0,Te1 Yaw and Pitch angles In this case, *illustration2*, there is a separate projection plane per Snapshot, right? (red, green and blue planes belongs to each colour coded camera) How are common features(control points) handled, to make optimization? I guess your reference to instability in optimization is that a camera could "look" away from a subject plane altogether, right? 2009/10/11 Pablo d'Angelo <pablo.dang...@web.de> > > As hinted in an earlier mail to hugin-ptx, I have added two more > parameters that allow specification of the plane on which the off center > images should be projected for each image by means of "plane yaw" (Te0) > and "plane pitch" (Te1) parameters. > They define the normal of the plane in 3D space, similar to yaw and > pitch, which define the looking direction of a camera. > > > --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "hugin and other free panoramic software" group.
