The Design And Implementation Of Image Stabilization Technology Based On Nios Ⅱ

When shooting on the carrier,as carrier varying attitude and vibration influence,will lead to the image toblurred,difficult to observe.Image stabilization is atechnology to eliminate random vibration make image stabilization and clear.Whilethe electronic image stabilization as a image stabilization method has a highprecision,small volume, low power consumption,high intelligent etc,make it becomeinto a top topic of the video processing field at home and abroad,compared with thetraditional optical, mechanical image stabilization technology.The electronic image stabilization calculated using the algorithm of stabilizationframe motion vector random,and reversed compensation,eliminate the influence ofrandom vibration on the imaging,achieved the purpose of stable video images. Invideo image processing requirement of real-time,the paper combined with theembedded system development new hot Nios Ⅱ,based on the Nios Ⅱ hardware systemto achieve electronic image stabilization method is proposed.In this dissertation,the electronic image stabilization based on gray projectionalgorithm is mainly elaborated,which is succeed to transplant on Nios Ⅱ hardwaresystem,achieved electronic image stabilization base on Nios Ⅱ electronic imagestabilization. electronic image stabilization algorithm researched mainly through grayprojection algorithm simulation and verification,the applicability and feasibility ofthis algorithm is improved and is verified.The system’s hardware into imagecapture,stabilization algorithm, display three modules were realized,which imagecapture,display module were realized through user custom IP core ofmethod,stabilization algorithm were realized using to program corresponding Clanguage,three modules were combined up by builting Nios Ⅱ hardware system.Experiment shows that based on the electronic stability Nios Ⅱ as system caneffectively eliminate the random motion on the camera platform, achieve imagestabilization expected effect.
