If SynthEyes finds any trackers that are further than 1000 times the world size from the origin, it will not save them as “solved.” You can use the Script menu’s Select By Type script to locate and select Unsolved trackers (or select unsolved trackers in Synthia). You can change them to Zero-weighted to see where they might fall in 3-D, and prevent them from affecting future solves.
Frequently these trackers should either distant horizon points that should be changed to Far, corrected, or deleted if they are on a moving object or the result of some image artifact. Such points can also arise when a tracker is visible for only a short
time when the camera is not moving. The Clean up trackers dialog can do this automatically.
Note: the too-far-away test can cause trouble if you have a small world size setting but are using measured GPS coordinates. You should offset the scene towards the origin using the Shift Constraints script.
You should also look for trackers that are behind the camera, which can occur on points that should be labeled Far, or when the tracking data is incorrect or insufficient for a meaningful answer.
After repairing, deleting, or changing too-far-away or behind-camera trackers, you should use the Refine mode on the Solver panel to update the solution, or solve it from scratch. Eliminating such trackers will frequently provide major improvements in scene geometry.
