System INDELA OGD-20HIR allows for an aerial photography and reception of color, black and white video images and images in infrared spectrum on the GCS monitors. Photography can be made at day and night hours.
Active two-axis stabilization and target range estimation are additional advantages of the system.
Video processor provides constant automatic video tracking of the object selected by the operator, (auto tracking), and it can process video signals simultaneously received from the thermal imager and color camera.
Auto tracking function has two modes: target acquisition mode and tracking mode
Mode "picture in picture" allows for displaying on the monitors images simultaneously from two video channels: video from one channel is sent to the display output channel and the image from another channel is overlaid as video window on the display image area. The user can select which signal source is to be displayed on the whole screen and which in mode “picture in picture”.
Stabilization level System INDELA OGD-20HIR is equipped with two-axis gyro-stabilized gimbal, providing new stabilization level due to specialized wide band torque sensors, modern program algorithms, the latest gyro sensor and the accelerometers of leading world producers.
The function of electronic stabilization allows for compensating of horizontal and vertical oscillation of the camera as well as visual comfort for the user. System working principle is an oscillation tracking of the input image and further picture displaying without oscillations.
Inertial system3D inertial system is mounted within the body directly on the optical unit; it allows to implement advanced functions and to improve digital control.
