Customized Lens, filters, Stable Mount

3. Camera Metric Stability?
Metric implies that the system is calibrated for interior orientation and remains STABLE over time
Principle Point
Lens Distortion
Focal Length
+ Shock & Vibe and Pressure Tested= Mapping Grade Camera VS
Self Calibration method using AT to determine interior orientation using tie-points and Ground Control

4. Camera test labs and manufacturing facilities
Applanix Camera Manufacturing Lab
Precision CNC Machine
Reasons:
Improve overall quality and re-duce re-work time via improved tooling
Shorten manufacturing time via improved tooling
Shorten turn-around times on re-calibrations for the yearly maintenance
Terrestrial Camera Calibration Cage
