boaz,

Yes, you can add in the VBScript module just before you send out the variable to the servos and include the following code.

cogX = GetVariable("COG_X")
if cogx = "" then
cogx = GetVariable("LAST_COG_X")
SetVariable "COG_X", cogx
end if

SetVariable "LAST_COG_X", cogx

which will use the last non-zero COG_X value if the current one is zero. It will also update the LAST_COG_X variable with the current coord if not zero.

You'd need to also do this for COG_Y.

You can also put in a counter that if after say 10 times of being zero you'd then assign zero to COG_X if you needed at some point the values to be zero.

Or you could also average the past values .... lots of options here!

STeven.

correction- the COG_X\\Y gives N\\A ( not a 0)..

(is their any way to change a post ?)

transfering variable from previous frame-using VBScript

Tue, 30 Nov 1999 00:11:00 EST

hi
i have built a pan-tilt webcam using BrainStem controller.
when the program run the COG_X\\Y is flickering in the same rate if FPS.
in some interval of 15-25 frame it throws 0 to COG and the Pan-Tilt loos the direction.

is their any way to transfer the SERVO_VALUE or COG_X\\Y from the previous frame using VBScript module?
or a better solution to avoid the 0 that i get ?

Regards

boaz
