Scale-Bar Weight Factors

In the Bundle Adjustment window, you will notice a section for Scale Bar Weight factors. This section allows you to control the manner in which scale-bars are incorporated into the final solution.

You may change the state of the check-box to determine whether scale-bars are weighted based on their uncertainty. If this box is checked, the relative uncertainties in the Scale-Bar database will be used to weight those scale-bars with a higher accuracy more than those scale-bars with a lower accuracy (or a higher uncertainty). Basically, this check-box controls how multiplier scale-bars are compared to each other during the bundle solution.

In addition, you may enter a numerical weight that is applied to ALL scale-bars during the solution. This value defaults to 1.0, but may be increased or decreased at the user’s discretion. Note, however, that this value is independent of the state of the check-box. You may weight scale-bars based on uncertainty and/or apply an overall weight. This is because the overall weight is applied after the uncertainty weight is applied.
