Improvement of the Optical Navigation System Using the Mutual Information Function

In this paper, based on the analysis of known navigation methods, an improvement of the optical navigation method is proposed. The essence of improvement is as follows. When using the indicators of additional sensors of the system and the function of mutual information between the reference and the images created on board the UAV, a fused image is built, which makes it possible, in the presence of interference, to identify and recognize objects with a greater probability and determine the coordinates and parameters of the carrier’s motion. The construction of a navigation system based on MEMS structures reduces the mass and dimensional parameters of the system, energy consumption, and increases reliability. The algorithm of the system operation is developed, and an example of implementation is given.
