Gyro-Stabilized Platform for Multispectral Image Acquisition 119
The conceptual work ended with the presentation of two variant of the construction
of the platform (fig. 3). Both options took into account the dimensions of
the propulsion systems and the required amount of space for mounting control
electronics and connectors.
Fig. 3. Two variants of the construction of the platform. Both were considered during conceptual
phase of work
For implementation the second variant presented in fig. 3b was chosen. It was
characterized by a larger volume of the cassette assembly. Such construction allows
convenient installation of cameras according to the designated parameters
from section two. Size of the chosen cassette allows precise installation of the
inertial measurement unit (IMU) which is used in order to determine the orientation
in space. Chosen variant also leaves space for future redevelopment due to
additional equipment like e.g. laser range finder.
5 Platform Design and Construction
The concept selected during previous stage of work was developed during design
phase into a complete model for CAD/CAM platform (fig. 4). It allowed rapid
generation of design documentation. The project was also used during creation of
device components using CNC milling machine. Constructed fully functional
prototype made of aluminum is shown in fig 5. The main requirement for the design
phase of the work was to enable line of sight stabilization during rapid vehicles
movements [9].
