Adding pitch and roll

[dtapia]

Hello,

I am trying to add roll and pitch tags. I saw a sampe config file (https://www.exiftool.org/config.html) which defines those tags I need. I renamed it to ".ExifTool_config" and I added  "exiftool -config .ExifTool_config" to the .bat file, but when I try to define those tags to photos, they doesn't appear...

I know I am doing something bad, but I dont know what,

Thanks a lot.
Regards.

You only need to rename the config file to ".ExifTool_config" if you want it to load automatically.  It can have any name if you load it with the -config option.

What command are you using to write these tags?  And what messages does exiftool give in response?

I am importing from a csv file. I got longitude, latitude and altitude but I cant display pitch and roll.

this is my command line:
exiftool -csv="GPS.csv" *.jpg

and this my csv:
SourceFile,GPSLatitude,GPSLongitude,GPSAltitude,GPSPitch,GPSRoll
ladybug_panoramic_000000.jpg,36.70900498,-4.413488588,5.2,179,5
ladybug_panoramic_000001.jpg,36.70897114,-4.413526776,2.1,5,12
ladybug_panoramic_000002.jpg,36.70892795,-4.413555432,7,7,15

Using your CSV file with the first file name changed to "a.jpg", and using the "example.config" file from the full distribution, this works for me:

Hello Phil,

I tried it and it worked like you did. Just one thing: i go to the properties of the photo-->details and I only see longitude, latitude and altitude. Roll and pitch cant be displayed in that menu? and could I set Yaw with exiftool?

Thanks.

You don't say what you're using to view the properties of the file, but it's quite possible that it just doesn't read that data.

[Phil Harvey]

This is non-standard EXIF, so other apps will only read it if you can configure custom tags.

You can use the standard GPSImgDirection for Yaw.

Hello

I am training this software, and I am using windows properties to see them at this moment, hehe

Hello phill,

I am trying to use GPSImgDirection for yaw, but I have a problem. Negative numbers for yaw aren't displayed at their respective photo. I tried to use GPSImgDirectionRef T and M but the problem is still there. How can I assign those negative numbers to the photos?.

For example:
SourceFile,GPSLatitude,GPSLongitude,GPSAltitude,GPSRoll,GPSPitch,GPSImgDirection,GPSLatitudeRef,GPSLongitudeRef,GPSImgDirectionRef

ladybug_panoramic_000000.jpg,36.70900498,-4.413488588,5.942606865,179.1635888,0.179976437,42.17153229,N,W,M
ladybug_panoramic_000001.jpg,36.70897114,-4.413526776,5.834002511,178.1573564,0.390092805,38.51711711,N,W,M
ladybug_panoramic_000002.jpg,36.70892795,-4.413555432,5.737311878,177.2469652,0.280327485,6.642170491,N,W,M
ladybug_panoramic_000003.jpg,36.70888011,-4.413534567,5.71169086,178.1952329,-2.747015889,-62.4382638,N,W,M

photo number 000003 doesnt show the GPSImgDirection in other programs, but the other photos yes.

Thanks.

GPSImgDirection must be between 0 and 360 according to the EXIF spec.  So -1 should be written as 359.

Hello Phil,

So, in my case, I have to change one by one each negative data, haven't I?

[Phil Harvey]

No.  You can use the following config file and change the column heading to GPSYaw to do what you want.

Code Select Expand

%Image::ExifTool::UserDefined = (
    'Image::ExifTool::Composite' => {
        GPSYaw => {
            Require => 'GPSImgDirection',
            ValueConv => '$val[0] - ($val[0] > 180 ? 360 : 0)',
            Writable => 1,
            WriteAlso => {
                GPSImgDirection => 'defined $val ? $val + ($val < 0 ? 360 : 0) : undef',
            },
        },
    },
);

1; #end

Assuming the config file is named "gpsyaw.config", the command would look like this:

exiftool -config gpsyaw.config -csv="GPS.csv" -ext jpg .

This will accept GPSYaw values from -180 to 180, and write the corresponding value for GPSImgDirection in the range 0 to 360.  It can also be used when reading to do the reverse.
