Prediction of aerial-image motion blurs due to the flying vehicle dynamics and camera characteristics in a virtual environment

This study presents comprehensive studies on practical means to predict aerial-image motion blurs due to the flying vehicle dynamics, including flying altitude; cruising speed; and angular velocities and finally installed camera characteristics; such as, frame rate and image size. The resulting predictions of blur values are in-turn used to generate blurry images to be fed as input data for later use in a de-blurring-in-the-loop of a Mono-simultaneous localization and mapping system. The whole process is coordinated by means of an integrated aerial virtual environment. The integrated aerial virtual environment consists of a three-dimensional graphical engine which could communicate with a full six-degrees of freedom aircraft dynamic simulator to precisely generate trajectories of the flying vehicle. Any accumulated real-time image taken by the camera installed on the aircraft during its mission considers the relevant vehicle states for necessary adjustments. The authors practically exploit C++, High-Level Shader Language, as well as JSBSim to expand the components of the package. Extensive case-studies show that the developed approach is quite effective in controlled environments.
