- Readme PTStereo 2.1
- Changes to version 2.0b3:
- o first Linux and Win32 version.
- Changes to version 2.0b1:
- o Arbitrary many input images can
- be used
- o Map-to-map option: A map or ground plan
- of an object can be used as one
- of the input images.
- o World coordinates of camera positions
- are individually settable or can be
- calculated.
- o 3DMF output option added.
- Changes to version 0.1:
- o Textures for texture mapping can be selected from
- different images.
- o Front end 'PTPicker' added for simple
- triangulation.
- o Versioning has been adjusted to the
- library file 'pano12.lib'.
- General:
- =======
- PTStereo creates 3D-worlds from sets of photographs.
- Applications range from object movies to terrain
- visualization. Any set of images can be used
- without alignment requirements. 3D-data can be
- extracted for any feature visible in both images,
- as long as the images have different viewpoint
- (non-zero stereo base).
- User input involves the triangulation of all
- images: Corresponding feature points have to be
- identified, and connected to a mesh consisting
- of triangles. The output of PTStereo is a
- 3D-world ready to be viewed with any VRML or 3DMF-browser.
- This world consists of a texture mapped indexed face
- set. In addition, world coordinates of all feature
- points and camera positions are calculated and
- can be used for measurements.
- Installation:
- =============
- Same as PTStitcher.
- Using PTStereo:
- ===============
- PTStereo should be used as helper for the
- frontend 'PTPicker'. Using PTPicker, a textfile
- is generated consisting of feature point coordinates
- and triangles. Download the file
- <http://www.fh-furtwangen.de/~dersch/examples.zip>.
- for an example.
- More Uses:
- ==========
- (1) The final Project file contains
- vertex coordinates in Meshwork syntax. These
- can be cut and pasted into mesh file to
- generate a 3D-mesh for editing in Meshwork.
- (2) The final Project file contains
- commands ('o'-lines) for Panorama Tools:
- Execute these lines in the adjust-submenu
- (mode 'insert', 'use script') and the images
- texture0.jpg and texture1.jpg are transformed
- to have parallel film planes. They can then
- be used for view interpolation with any
- Morphing software, or for stereo viewing.
- Accuracy depends on the distance of an object relative
- to the stereo base. Distances much larger (eg > 20 times)
- or features much smaller than the stereo base are not well
- resolved.
- Enjoy.
