Thank you very much for your hints. I tested your code 
for (split(/:/, $$pattern)) {
    $_ = 'S0' . $_ unless /^S/;
    $_ .= 'S0' unless /S\d+$/;
    print STDERR "pattern: $_\n";
    my @pieces = split(/[SF](\d+)/, $_);
    foreach my $count (0..$#pieces) {
        print STDERR "$count -> [$pieces[$count]] ";
    }
    print STDERR "\n";
}

But I got an odd output. Split gives back some empty items 
pattern: S51F11S0
0 -> [] 1 -> [51] 2 -> [] 3 -> [11] 4 -> [] 5 -> [0]

Changing split to match only /[SF]/ (your update suggestion) and adding a shift afterwards improves the output, 
pattern: S51F11S0
0 -> [51] 1 -> [11] 2 -> [0]

leaving me with the second problem, i.e. that having an odd number of items in my array, splice(@,0,2) will give back an undefined second element.
Nothing catastrophic, but it is going to increase the number of necessary checks.
Even if it doesn't do what I need, though, this code of yours gives me some ideas that I can further develop.
As for the second hint: 
tr/ //d;
$camel .= $_;

yes, it looks much faster (not to mention smarter) than my code.
