Hi Guys,
I've felt the need to post a few times in 3 yrs, and this is one of them :)
I tried to go back and thank contributors of another thread, but it was locked
(likely because it was resolved, or 3 years old!).
I'm writing for a camera equipped computer, tracking a red laser beam reflected off a blank wall,
and looking to improve a part of it's software that determines what a laser dot looks like
at current lighting levels, compared to the rest of a wall before it can track it.
This is because it does not just look for the brightest camera pixel, which would be easy,
but the centre of the circular object it sees on the wall, of a colour within a tolerance of
the one gained at startup.
The three colour component values of the colour with the highest red value for a particular frame were actually:
R:0.619608 G:0.576471 B:0.533333
Where 1 is the highest possible value for each component.
I find that red is never much higher in the centre of the beam reflected off a white wall,
but red IS always higher than green, and both of them are always higher than blue.
Is this because red is further away from blue than green in a rainbow?
I'm serious.
Thanks :)
