FASTER Engineering Model

The camera has an all plastic structure so it is therefore necessary an adequate

protection when installed outside the aircraft.

It is fixed on a rapid prototyping plastic base which has been designed to perfect fit

the lower part of the camera body, avoiding rotations once it is mounted. To realize the

base, the EOS body has been digitalized through a three-dimensional scanner allowing

the extraction of the lower surface; the surface has been subsequently extruded to create a

printable solid. To achieve a better fixation the camera tripod mounting hole was used

too; the plastic base is provided with four holes used to install the assembly inside the

external pod. The supplied battery pack (Li-Ion, 7.4 V, 1050 mAh) usually in standard

operations guarantees no more than 300 shots, so it has been replaced with a power

supply adapter which permits a continuous power-on mode.

A built in SD card reader (with SDHC up to 32 Gbyte compatibility) is used only

when high frequency (1-3 fps) acquisition is needed. This because of the low USB data

transfer rate, which is suitable only for low frame rate (< 1 fps).

The camera is normally set to manual mode to permit an enhanced management of

the acquisition parameters. Camera configuration is managed by a very light, custom
