摘要 摄像机运动时,处于不同景深的景物在成像面上会产生不同的运动矢量,传统电子稳像算法无法有效解决该类问题。为此,利用成像关系系统,分析电子稳像中摄像机运动对景深场景成像的影响,通过对景深场景的实验验证,提出一种考虑景深问题的运动矢量权值分配补偿方法。实验结果表明,与现有的全局运动矢量补偿相比,该方法可以获得更好的补偿效果。 When the camera moves,scene in different depth field produces different motion vector in imaging surface,in the past,the Electronic Image Stabilization(EIS) algorithm can not solve this problem effectively.This paper analyzes the imaging relationship of the camera movement on the influence of depth scene imaging,through experimental verification and theoretical derivation,it presents a method of motion vectors weights allocation compensation considering the depth field problem.Experimental result shows that this method is more effective than the existing global motion vector compensation,it has better compensation effect.
