[Abstract]:The traditional image de-shake research is mostly based on the video image output signal as the object of study, this research is mainly using electronic image stabilization algorithm for television image stabilization simulation experimental research. With the wide application of unmanned aerial camera, how to improve the image quality of unmanned aerial camera and remove the image jitter caused by all kinds of flight motion, Eliminating the ambiguity and jitter caused by irregular random motion to the image sequence acquired in aerial photography, ensuring the stability and clarity of the high-definition jitter image, so as to accurately convey important regional information. This has become the most important topic in the application of aerial camera high-definition jitter image of unmanned aerial camera, and has strong research value and wide application field. In this paper, aiming at the necessity of detrembling of high-definition jitter image of unmanned aerial camera, this paper introduces the system structure of unmanned aerial camera, analyzes the causes of aerial camera high-definition image jitter, and points out the setting of key parameters of aerial camera of UAV. After that, the high-definition jitter image of unmanned aerial camera is analyzed, and after studying and researching the technology of image stabilization, In this paper, another method of dejitter of high-definition jitter image of unmanned aerial camera is presented, which is based on ProDAD Mercalli software, and its effect is compared and analyzed scientifically. At the same time, the evaluation method is provided. The data acquisition equipment used in the experiment is the multi-rotor unmanned aerial camera built by the author. The experimental data are taken from the high-definition jitter image of the actual aerial camera, which basically reflects the actual operation process of the unmanned aerial camera. Under the influence of attitude change and vibration caused by the flight platform, camera system and electronic shock absorber of unmanned aerial camera, the obtained high-definition jitter image signals contain many irregular random motions, thus causing different image jitter. The purpose of the experiment scheme in this paper is clear, the experimental object system is comprehensive, the experimental data has strong typicality and objectivity, and has strong practical reference value.
