message: Would Microsoft Live Labs Photosynth and Google Street View be considered examples of Photogrammetry applications?  —Preceding unsigned comment added by 74.248.228.189 (talk) 20:10, 2 September 2007 (UTC)
replies: text: Both packages employ 3D models, Photosynth via photogrammetry, Google on the other hand may not generate its models from images. --krioboy 00:06, 4 December 2007 (UTC)

text: Should we mention Photosynth, we should also mention other software packages typically used in photogrammetric reconstructions (Autodesk Imagemodeler, EOS Photomodeler). Photosynth is nice, it has inovative user interface, but the algorithms (calibration, matching) are "just" implementation of already known algorithms.  —Preceding unsigned comment added by 81.201.48.25 (talk) 11:36, 26 December 2008 (UTC)
thread_title:  Another example? 

message: This is an individual's opinion, not fact nor consensus. Photogrammetry forms the very foundation of so-called "Geomatics" (which itself is the fusion of geophysics, geography, engineering, geology, geodesy, surveying and computer science) and is constantly being used as more and more planet observation satellites are launched for remote sensing. Satellite stereo photogrammetry plays a crucial role in updating terrain maps (DTM, DEM), hydrology maps and furthering our knowledge of the geoid in great detail.  —Preceding unsigned comment added by Mxbuck (talk • contribs) 19:53, 8 April 2009 (UTC)

message: Should the table of software be moved to its own wiki page, e.g. "Comparison of Photogrammetry Software"? --LeBoef (talk) 09:38, 16 January 2013 (UTC)
replies: text: if so, the table should be expanded to include, e.g., information on the availability and cost of educational licenses. HMallison (talk) 23:08, 18 March 2014 (UTC)

message: I'm rather surprise to not see it here.  It was actually the best online service I've come across when I was doing evaluations three years ago, and I doubt that they devolved since then.  Here is their website for Areograph: http://areo.co.nz/areograph/  (Areoscan and Areohawk are (I'm assuming) extensions of AG.)  — Preceding unsigned comment added by DeadlyDad (talk • contribs) 16:45, 9 January 2014 (UTC)

message: ::Photogrammetry is an estimative scientific method that aims at recovering the exact positions and motion pathways of designated reference points located on any moving object, on its components and in the immediately adjacent environment.
Huh? And why is so much of this in italics and bold? 15:57, 30 April 2014 (UTC)

message: There's a template for "lumberjack sports" at the bottom of the article, which does list photogrammetry. But this article doesn't discuss any competitive aspect(???) or lumberjacking, and lumberjack sports doesn't mention photogrammetry at all. What gives? — Gwalla | Talk 20:56, 30 April 2014 (UTC)

message: Photogrammetry normally implies stereo, with very little work done on a single image, so there's no need for dedicated section for stereophotogrammetry -- otherwise, it'd need a pairing monophotogrammetry section -- so I plan to delete that section. Fgnievinski (talk) 03:06, 24 June 2015 (UTC)
replies: text: Photogrammetry is a broader term than stereophotogrammetry and doesn't necessarily imply stereo, hence the section about stereophotogrammetry. Photogrammetry can for example be used to estimate a 3D model from a single photo, either by looking at shapes in the image (see , ,  or ), or by looking at the shadows in the image such as the shadows due to roughness in the surface of a celestial body. It can also be used to estimate the temperature of glowing objects by looking at the color of the emitted light. I would say add a pairing section about monophotogrammetry if you think that is suitable. —Kri (talk) 18:21, 24 June 2015 (UTC)
replies: text: I dispute that stereophotogrammetry is a "A more sophisticated technique" than photogrammetry; rather, it's a special case of photogrammetry. As such, I've moved the offending part under the Methods sections. Fgnievinski (talk) 19:14, 24 June 2015 (UTC)
replies: text: Citing sources could resolve a dispute if one exists.  Blue Rasberry (talk) 20:29, 24 June 2015 (UTC)
replies: text: I fully agree that stereophotogrammetry can't be called a more sophisticated technique than photogrammetry; whoever wrote that obviously didn't realize that any stereophotogrammetry technique is also a photogrammetry technique. —Kri (talk) 21:25, 24 June 2015 (UTC)
replies: text: Fgnievinski, why do you keep reverting the category/see-also-link changes I make? This page talks about stereophotogrammetry, why it should be categorized with :Category:Stereophotogrammetry. This in turn makes :Category:Photogrammetry superfluous, since it is contained within :Category:Stereophotogrammetry, if you wonder why I first removed that category. I also added a link to Computer stereo vision since it is a closely related subject. I can leave the link to Computer vision if it is relevant, but I still think Computer stereo vision should be listed in the "See also" section. Don't you? Stereophotogrammetry is a redirection page and should have no see-also links. —Kri (talk) 07:34, 25 June 2015 (UTC)
replies: text:  I think you're getting categorization wrong. The article Photogrammetry describes more than stereophotogrammetry. This is reflecting in :Category:Photogrammetry, which contains :Category:Stereophotogrammetry as a sub-category -- the latter is a type of the former. Then the article Photogrammetry and redirect Stereophotogrammetry are to appear at the start of their respective category listings; pls see WP:EPONYMOUS for details. Fgnievinski (talk) 18:05, 25 June 2015 (UTC)
replies: text: Okay, so this page should be listed in :Category:Photogrammetry. But shouldn't it also be listed in :Category:Stereophotogrammetry, as it is partly about that subject? —Kri (talk) 22:57, 25 June 2015 (UTC)
replies: text:   Yes and no: :Category:Photogrammetry is already listed as a parent of :Category:Stereophotogrammetry, at the bottom of the page; if :Category:Photogrammetry didn't exist, then it'd be okay to make article Photogrammetry a member of :Category:Stereophotogrammetry. Fgnievinski (talk) 19:24, 26 June 2015 (UTC)
replies: text:  But if you want to find articles that touch the subject stereophotogrammetry, you go into :Category:Stereophotogrammetry and look for articles there, so clearly, it should still be listed there for that reason, right? —Kri (talk) 11:43, 27 June 2015 (UTC)
replies: text:   By "it" I supposed you mean article photogrammetry; actually, it suffices to have the redirect stereophotogrammetry as a member of :Category:Stereophotogrammetry. Fgnievinski (talk) 02:26, 29 June 2015 (UTC)
replies: text:  Okay, thanks for the reply. Yes, by "it" I meant this article; I see that was a bit vague. —Kri (talk) 19:59, 30 June 2015 (UTC)
thread_title:  Stereo vs. mono photogrammetry? 

message: you might want to check these two categories, as they seem to overlap substantially. Fgnievinski (talk) 18:11, 2 July 2015 (UTC)
replies: text: It seems like there are a lot of different but very similar articles that are all about 3D reconstruction from images or videos; maybe the same is true for the categories they are in. As of :Category:Geometry in computer vision, it seems to me that it is a broader category than :Category:Stereophotogrammetry, as it relates to topics that are not in the scope of :Category:Stereophotogrammetry, such as the Pinhole camera model, and determining an objects pose. —Kri (talk) 19:14, 2 July 2015 (UTC)
replies: text:  Agreed there's undesirable overlap in articles; agreed also with the parent/child categorization hierarchy. And how about creating :Category:Computer stereo vision -- would it just redirect to :Category:Stereophotogrammetry? Fgnievinski (talk) 19:21, 2 July 2015 (UTC)
replies: text: I know too little about computer stereo vision. I think it sounds very similar to stereophotogrammetry but there could off course be some important difference between them. Maybe computer stereo vision also is a broader term than stereophotogrammetry and also deals with other things than just extraction of 3D coordinates (maybe such as poses), but these are really just guesses. —Kri (talk) 19:45, 2 July 2015 (UTC)
thread_title:  [[:Category:Geometry in computer vision]] vs. [[:Category:Stereophotogrammetry]] 

message: The history of photogrammetry receives only passing mention in the article; only that 'it is as old as photography itself'. The discovery of photogrammetric techniques and methods and pioneer applications deserves a section in itself. I will start one, but, please, will need help from those of you more in the know. My interest in the field is as a photographer who has stumbled across field striations when overlapping stereo views which appeared to have applications in range finding, only to discover the existence of this whole fascinating discipline of photogrammetry which brings together trigonometry and photography.
