- Transfer: Transfer the images from the camera to the computer.
- Match: Make sure that the images are matched in pairs (needed for multicoversion)
- Process: Read the left image, read the right image, align, save, repeat. You can do this manually or use multicoversion where you go have a cup of coffee, read the paper, and come back when everything is done.
First, I have the SD cards clearly labeled R and L, so there is no confusion which is which:
Here is how Windows Explorer (Windows 7) shows the two folders, when placed side-by-side. As you can see, the images from the L camera are upside down (click at the picture to enlarge).
Personally, I prefer to use "Open Image File List". Even if you use StereoPruner, you should become familiar with this SPM function because it is very useful.
Before we move to the final step, I want to make you aware of two things.
If you look at the pictures above, you will notice that the image numbering of the R and L files is totally different. For example, the first image in the L folder is SAM_9600, while the first image on the R folder is SAM_1337. These numbers are off by 8000+. I have done this on purpose.
If you format new SD cards and reset the image number, then the numbers from each camera will be matching. Eventually, with errors and orphan images, they will drift away but not by much. If the image names overlap, then SPM will not do multi-conversion correctly. In this case, you will need to rename one group of images.
You can rename the entire group of images (usually the L images) with SPM. While on the Image File List, go to “Edit”, then “Select All Files,” then right click and select “Multi-Rename”. This is a powerful function that allows you to do interesting renaming in the entire group of images. As powerful as it is, I prefer not to use it.
How did I change the file name sequence? I reset the numbering in only one of the two cameras at some point and this gets the numbers totally out of sequence. You can reset the file numbers via the menu, as I mention in this blog: http://drt3d.blogspot.com/2017/07/putting-twin-samsung-nx1000-camera-rig.html
After a while, the processing steps become automatic. If anyone has any ideas or thinks they are doing this much easier or faster, I’d like to hear from you.
