Spatial<br />
Offset<br />
Optical and indoor camera calibration procedures are designed to derive<br />
the internal characteristics of the imaging system (IOP) within<br />
controlled environments. However, there might be a possibility that the<br />
estimated parameters from an indoor camera calibration exercise are<br />
different from those estimated through an in-situ calibration under<br />
operational conditions. Therefore, it is always recommended to carry out<br />
an in-situ camera calibration to evaluate the differences, if any,<br />
between estimated IOP from in-situ and indoor calibration procedures.<br />
The discussed evaluation measures in the previous section can be used to<br />
quantify the differences between these IOP sets.<br />
