The present invention relates to a method for acquiring an optimal closed-curved image by using multiple cameras and, particularly, provides an image providing method for producing one image by usingmultiple cameras having different capturing viewpoints and fixed to a rig. To this end, the image providing method comprises: a projection step for acquiring one image by projecting images obtained bymultiple cameras on a closed-curved projection surface, using parameter information; a rendering step for fitting the acquired one image into a quadrangular frame through a sampling procedure which is performed non-uniformly for each area; and a viewing step for mapping the sampled image to a viewing sphere. 本发明涉及一种通过拍摄时间不同的多个相机获取优化的封闭曲面影像的方法，特别地，本发明涉及利用固定于联盟的具有不同拍摄时点的多个相机制作一个影像的影像提供方法，其包括：利用所述多个相机的参数信息，将所述影像投影于非定型封闭曲面型投影面，以获取一个影像的投影步骤，通过在各领域对所述获取的影像进行不均匀样本化，将其拟合为四角帧的渲染步骤；以及将所述样本化的影像映射于观看球面的观看步骤。
