How to make a panorama in a small room

by jjackson » Tue Jan 14, 2014 6:59 pm

Hello,

Our company makes fancy closets. Sometimes the space is very small. We would like to make a panorama of the cabinetry for presentation on our web site.

The sample wall we are testing with is about 7 feet high, 12 feet long and I can get back about 5 feet from the cabinets.

We are trying to use Autopano Giga Trial to see if it will solve the problem.

I set up the tripod in two locations and shoot maybe 20 to 25 pictures from each location and process in autopano giga with multiple view points checked. What we get is each tripod location is recognized and a panorama for each is generated, but with every projection there is distortion of some sort. Each panorama is not bad, but if we say 'use all pictures' it just makes a mess. We also tried taking 25 pictures each straight on to the subject but the camera moves parallel to the wall. That turned out not well at all.

Planar projection works best for us but at the ends the parts are distorted.

If anyone can offer some tips it would be appreciated.

Welcome to the forum...

You have to shoot from a single location and (probably) use a spherical projection when rendering.

You will probably need a fisheye lens and you will need a proper pano head.

What a camera and lens are you using at the moment?

Are you intending for the person viewing the pano on the web site to be able to pano and zoom on the panoramic images?

When you are photographing a 12 foot length of wall from 5 feet there's bound to to be distortion because of the field of view (you have to be able to get much further way to reduce that).

But if you use Panotour/Panotour Pro to prepare the images fro use online the viewer will acommodate that.

I am using a Canon G9 which has a 35mm equivalent wide angle, and have a Canon 0.75x adapter that fits over it, giving me not quite 28mm. I am using a tripod and have a pistol grip ball head so I easily can pivot in any direction without moving the tripod.

Forget it. You need a fisheye and a real NPP(aka Nodal)-adapter. With the equipment you described you´ll run into nothing but issues.

Using your lens on this small sensor you´ll need too many pictures - without being able to align them properly.

good luck, Klaus

Our initial tests today using this camera were not too bad. I would shoot the wall using 3 or 4 rows of 4-5 pictures. Autopano used them all and stitched them very well.

Sounds like Autopano Pro would meet our needs, and the features of Giga are more than what we need.

Thanks for all the advice.

Sorry - i didn´t realize you´re NOT heading for interactive, sperical panos. So a fisheye in your case wouldn´t be the way to go.
