Cannot disable automatic white balance and set exposure

[Wen_L_]

Hi,

I'm trying to track and recover pose using colored patterns with the RGB camera from R200, however either white balance and/or exposure often washes out the pattern (colors become white with different lighting/background). I've tried to disable both exposure (SetAutoColorExposure(false)) and white balance (SetAutoColorWhiteBalance(false)) and although both functions return no error (PXC_STATUS_NO_ERROR) we still observe the same effects. I've also tried to set the value for white balance (SetColorWhiteBalance) which returns an error (PXC_STATUS_DEVICE_FAILED)

Please advise.

Thanks!

A little history on F200 first. For early versions of the F200 DCM, you had to first use  SetColorAutoWhiteBalance, SetColorAutoExposure with parameter auto = false - that sets it to manual, and then set with value succeeds. For F200, DCM 1.3 fixed this issue so that setting the value also set auto control to manual.
On R200, I've seen reports that the setting didn't take until a 2nd time -or that it took much longer than expected (>100ms).
