Video Simulation
Simulation
In parallel with the development of our image processing elements, sub-systems and systems, Octec have developed tools for the simulation and analysis of electro-optical-based systems. These tools were developed to quantify, control and validate real, operational scenarios encountered by electro-optical systems in operation, thus providing consistency in evaluating system performance and excellent training for the users of such systems. Today, these tools are available as stand alone products.
Scene Builder
Octec's Scene Builder has been designed to allow the construction of synthetic 3-D scenes using texture images, height maps and 3DS objects. The resultant output file is used by Octec's Scene Simulator to generate real time video of the scene. The scenes produced by the RVS facilitate the simulation of video for both development and training applications.
Scene Builder features include;
- Windows XP, 2000 compatible running on PC;
- Scene construction based on 3DS objects, texture images and height maps;
- File, New, Open, Save, Export and Exit functions;
- Environmental options of Fog, Colour, Waves (Naval), Sky, Cloud);
- Object selection from database (Aircraft, Ships, Buildings, Trees etc);
- Object Position, Orientation, Size and Behaviours;
- Naval, Air-to-Ground and Air-to-Air scenes can be constructed.
Scene Simulator
The Scene Simulator produces real-time Video sequences from a computer generated synthetic camera viewing a 3 D Scene, where the Cartesian position, angular orientation and Field of View (FOV) of the camera can be altered. The Scene Simulator runs under XP on PC with a PMC graphics accelerator.
Scene Simulator features include;
- A real - time, 3D scene / target simulator
- Standard Window XP PC with graphics accelerator card
- PAL/CCIR/RS170/NTSC Video output
- 2, RS232 ports for external AVT and control panel interfaces
- Full symbology capability
- Commercial off-the-shelf (COTS) products.
Uses pre-programmed scenes from the Octec Scene Builder (not included). These scenes are constructed from a texture image and a height map, and 2/3 dimensional objects including: Aircraft, Ships, Buildings and Trees. Visual and IR scenes or Naval, Air-to-Ground and Air-to-Air engagements are available. The Scene Simulator runs under Windows and is written in C/C++ and uses the OpenGL interface. A Synthetic laser and Head-Up-Display are available as well as video with or without symbology.
The Scene Simulator can be used to evaluate closed loop Automatic Video Tracking (AVT) of various targets with various dynamic platforms. The real-time video is passed to an AVT and the resultant target-to-boresight errors are passed to the control loop PID to control the orientation of the platform and attached camera. If the platform has a velocity (land vehicle, ship of aircraft) then the position of the camera will also alter.
