Hello Ingsayyad,

Error values are calculated as a difference between measured (source) and estimated values. You've got source values, but to have estimated values it is necessary to define at least two projections for each marker on different aligned photos, since the single projection on a single image doesn't define 3D position for the marker is space and actually corresponds to the ray.
