Bionic electronic image stabilization method and device based on vestibular reflex mechanism

Abstract

The invention discloses a bionic electronic image stabilizing method based on the vestibular reflection mechanism. The method comprises steps that, vestibulo-ocular reflection of the left eye and the right eye is simulated by two cameras; abrupt current change of a first motor and a second motor is measured by an FPGA board card to acquire a rotation acceleration of the two cameras; strain of a first strain gage force sensor and a second strain gage force sensor to acquire a translation acceleration of the two cameras; the rotation acceleration and the translation acceleration are fed back to an image stabilizing decision unit; matching motion estimation on previous / later frames of images shot by the two cameras is carried out by the FPGA board card, and the matching motion result is fed back to an image stabilizing decision unit; through an image stabilizing algorithm, the rotation speed and the rotation direction of the two cameras for compensation motion are acquired and are sent to a servo control unit, motion of the two cameras is controlled, and image stabilizing is realized. The method is advantaged in that, the image stabilizing algorithm is realized through FPGA, good stability is realized, vision errors caused by self rotation or translation of the cameras are eliminated, and the method further has advantages of high efficiency, short consumption time and good timeliness.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a bionic electronic image stabilization method and device based on a vestibular reflection mechanism. Background technique [0002] The vestibular organ of the inner ear is the balance receptor of the human body, which includes three pairs of semicircular canals and the elliptical sac and balloon of the vestibule. anatomy of inner ear vestibule figure 1 As shown, there are crests of the pot in the semicircular canal, and otoliths (also known as sac spots) in the elliptical sac. They are all vestibular terminal receptors, which can sense the stimulation of various specific motion states. The semicircular canal senses angular plus (decrease) speed motion stimulation, while the ellipse and the sac spot of the sac feel the change of horizontal or vertical straight line plus (minus) speed. When the vehicle we take rotates or turns (such as a car turning, an airplane making ...
