There is one non-column specific feature that helps when dealing with tables. This is discussed in more detail in the Photo Table chapter but as reminders we mention it here too:
• Use Table Configurations to get the specific columns you need for the job. You can use some of the configurations that come installed with the program but you can create your own or edit those pre-installed ones.
Here are a list of specific columns of the Photo Table and how they can be used for project assessment:
• RMS Residual – sort by this column to find the photo with the worst/best markings. If one photo has significantly higher rms residual then the marking is on average poor on this photo (or the photo is not oriented well). See Marking Residual.
• Largest Residual – sort by this column to find single points on photos that may not be marked well. See Marking Residual.
• # Referenced – sort by this column to check to see if minimum requirements are met for multi-photo projects (i.e. at least six referenced points). Photos with low number of referenced points may also not be oriented that well.
• Can be Processed – check this column when a photograph does not seem to be orienting. If it says "no" then some minimums are not being met (too few referenced points or too few control points, or too low photo coverage (i.e. all points in a small area), etc.
• Oriented – check this column to be sure every photo is oriented because no 3D data can come from an unoriented photo.
• Processing – check this column to remind you what processing status you have set for the photo (might help explain why it is not orienting or causing model distortion).
• Camera parameters – check over all these columns (focal length, principal point, format size, etc.) to ensure the camera parameters are consistent for all photos and they are what you expect. Also very important to check after camera optimization has been run to see how much the parameters vary photo to photo.
• Inverse flags – check these columns to remind you what camera parameters Orient/Inverse Camera will be solving for.
