| Summary: | Small Format Aerial Photography (SFAP) has various advantages, such
as: low operational cost, easy-to-obtain equipment, and rapid processing for data
acquisition. However, SFAP also has disadvantages in relation to geometric
accuracy and stability of camera lens, instability of aircraft movement during
exposure, and quality of position accuracy that has yet to be proven. SFAP has
been utilized to identify thematic information of earth�s surface for a reasonably
long time. Accordingly, it is potential that SFAP is to be used for spatial data
provision by minimizing its disadvantages. This research is aimed at developing
procedures for digital processing of SFAP for spatial data provision. The
objectives of this research are to identify and model the Interior Orientation
Parameter (IOP) of non-metric camera, to automatically and interactively extract
vertical position, and to study the quality of the resulted spatial data in
accordance to several spatial data specification standard.
This research was carried out in six steps. The first step is network design,
installation, survey and data processing of ground control points. The second
step is design and perform calibration of SFAF system to define IOP value and its
stability. Thirdly, aerial photography was carried out using ultra-light aircraft.
The fourth step is single and multi-photo processing. Single-photo processing
includes interior orientation and systematic error correction. Multi-photo
processing includes aerial triangulation (AT) adjustment, standard AT, and AT
with Additional Parameters (AP). The fifth step is automatic and interactive
extraction of 3D position. The final or sixth step is performing study on the
quality of spatial information.
Study results show that (1) to overcome IOP instability, in-flight camera
calibration is required |
