Hello all, and sorry to ask for what may be a dumb kind of question.
I've setup a video analysis room with high intensity lighting (pair of hykolity 19,500 lm lights), 2 high speed cameras (GoPro 10's) and can capture even 240 fps with brilliant color and sharp-as-tack focus.
Now, to be able to accurately judge scale, I want to add a scale poster to be even with the subject so I can use the scale tools in Kinovea. What on earth is the name of that scale "poster" (or is it just called a "scale poster"?) used in professional settings and where can I get one? I know I could just laser print a couple pre-measured, thick black lines on laser paper, but I want this to look professional, and be sturdy and durable.
I suppose a video calibration chessboard like poster would also be helpful. I can easily make one using Illustrator, but again I'd prefer one mounted on heavy cardstock as well.
I appreciate anyone who can point me in the right direction.
