How do I take pictures?
« on: March 31, 2011, 03:57:43 AM »
I mean.. do I ened to take them in order slowly rotating around an object?? Can I randomly take pictures from every angle?

How would I get a complete model of an object? Can I take pictures around the side aand also the very top and bottom of an object?

How realistic would it be to attempt to get a picture of someone in a T pose and clean it up and use it in a 3d package and rig it with bones/skin ?

well as long as Pictures have a good overlap, it should work..

thereis a very good explanation how to shoot pictures, even for the inside rooms, that was very inspiring.....

I see in the help file that they just do about 15 shots in a circle...

Do the overlapping shots need to be in order?

What if after the 15 shots in a circle.. I then want to do another 15 shots in a circle but this time at a higher angle.. will that confuse it ?

Is the best way to see how the tracking is going is to check how many points the prgram finds in the object of interest?

I havent had good results so far.

what type of camera you use ? use RAW format NOT JPG if can...
and i repeat, im using Canon 550D, 18 Mpix, will post some videos later on YT, and you will see that is no need for VERY much photos, jus try keep 60-80 % overlap (idealy). for litle building - church im need aprox 10 photos....

yes 15 shots in a circle and 15 shots taken at a higher point would work... you need to put them in 2 different chunks.. then later align these two chunks and then merge them..

Its just some casio thing up to 7MP.... can you put the orginal pictures up as well?? I have not tried something like a big statue.. I have been trying to do smaller items like a show on the floor... that didnt turn out at all..  and ofcourse trying to do human heads and whole bodies

aha!! So chunks are for when the collection of pictures is coming from a brand new angle?? maybe thats what I was missing.. I was doing 40 pictures from all different angles.. maybe I was confusing the program...

What if I put a object on a glass table.. would if be possible to have a COMPLETE 3d model from all angles ?

Back to beginning, shoot 20 images on 360 angle, then load to PhotoScan JUST 3 of them, try do mesh = OK im getting something
Phase two, try the same photos BUT add 2 more, - OK im getting more of what i need
phase three ad another 3 photos - OK im getting preciously what i nedd..

Is that simple, start with litle and the add more IF eventely needed, is from object to object.....
im testing iot on buildings and im getting wery useful output with around 8-10 photos, later on will add eventuely more, but every time is better to start with lower number of photos.....

ok... So rather than feeding it a truckload of photos I will just try the first 3... and if I can't get those 3 to look right then there is no need to continue.

got it!
