One of the algorithm is based on the Paraxial Helmholtz Equation: which describes the beam propagation through different media with different refractive indices, and the other is based on the concepts of optical computing: quasi-optical wave equations are solved numerically, using FPGA-accelerated hardware. The second algorithm describes a holographic pattern-matching algorithm. Both of the two FPGA-based implementations are very well parallelizable, consequently they are also be amenable to mega-core architectures.

The algorithm is based on the Paraxial Helmholtz Equation: which describes the beam propagation through different media with different refractive indices. To solve this wave propagation equation numerically the FPGA-accelerated hardware operates with spatially varying templates. The FPGA-based wave-equation solver is very well parallelizable, so the resulting algorithm will also be amenable to mega-core architectures.

The aim of the investigation is to show the strengths and weaknesses of these algorithms in the aircraft attitude estimation task. The work is part of a research project where a low cost UAV is developed which can be integrated into the national airspace. Two main issues are addressed with these measurements, one is the sense-and-avoid capability of the aircraft and the other is sensor redundancy. Both parts can benefit from a good attitude estimate. Thus, it is important to use the appropriate algorithm for the camera rotation estimation. Results show that many times even the simplest algorithm can perform at an acceptable level of precision for the sensor fusion. © 2014 IEEE.

The aim is to develop a low cost UAV which can be integrated into the national airspace (NAS). The sense-and-avoid (SAA) capability has to be reliably run by the UAV in any critical situations as well. The SAA task is solved via an electro optical sensor-processor module. This module is capable of running complex processing algorithms thus it can estimate the relative pose of the camera easily. These estimates can be used in critical situations when the on-board IMU fails or can be utilized by a fused IMU/visual sensor system in order to achieve better accuracy in camera based task. The exhaustive investigation of the proposed sensor fusion architecture is not complete, however, the presented results are promising and are an excellent base for the work which is currently running and will be finished in the near future.
