Is there Vuforia "bundle adjustment" sample code available?

I have a pair of static targets that I need to get a high-precision relative transformation matrix for. I'm still learning the ropes of augmented reality, but I think what I'm trying to do is called bundle adjustment, and involves using multiple measurements and finding a least squares average of them. Is there any code available showing how to do this? Basically I'm trying to reduce jitter when using the targets as part of a multi-target, and I can't get enough precision from just a single observation. Any advice would be appreciated.
