Pitch is not good when Yaw is <-150º or >150º #163

cursan-a commented 1 year ago

Issue Description

I just noticed that the pitch seems not good when Yaw is <-150º or >150º. Pitch go directly from -15º to 15º (without passing through valeur [14,-14]) even if I try to move really slow my visage

Steps to Reproduce

Just try it on the demo, place you face on the side (yaw <-150º or >150º). Move you face slowly up and down and look at the pitch value.

Expected Behavior

Having pitch going slowly from -15º to 15º.

i cannot reproduce as pitch angles i'm seeing change linearly and as expected even with extreme yaw values.
btw, do note analyzing extreme angles is not reliable to start with since most of face is obscured.
