Camera Calibration Process

We’re ready to start the camera calibration process, using the two shot sequences LeftCalibSeq and RightCalibSeq. You can start SynthEyes and do a File/New for the left shot, and then Add Shot to bring in the second. Open both with Interlace=Yes, as unfortunately both shots are interlaced. Even though these are moving-object shots, for calibration they will be solved as moving-camera shots.

You can see from these shots how the timing calibration was carried out. The shots were cropped right before the beginning of the starting flash, and right after the ending flash, to make it obvious what had been done. Normally, you should crop after the starting flash, and before the ending flash.

On your own shots, you can use the Image Preprocessor panel’s Region-of- interest capability to reduce memory consumption to help handle long shots from multiple cameras.

You should supervise-track a substantial fraction of the pom-poms in each camera view; you can then solve each camera to obtain a path of the camera appearing to orbit the stationary pom-pom.

Next, we will need to set up a set of links between corresponding trackers in the two shots. The links must always be on the Camera02 trackers, to a Camera01 tracker. This can be achieved at least four different ways.

 

Matching Plan A: Temporary Alignment Matching Plan B: Side by Side Matching Plan C: Multiple Camera Views Matching Plan D: Cross Link by Name Completing the Calibration
