Abstract: Disclosed herein are an apparatus for estimating a camera pose using multi-view images of a 2D array structure and a method using the same. The method performed by the apparatus includes acquiring multi-view images from a 2D array camera system, forming a 2D image link structure corresponding to the multi-view images in consideration of the geometric structure of the camera system, estimating an initial camera pose based on an adjacent image extracted from the 2D image link structure and a pair of corresponding feature points, and estimating a final camera pose by reconstructing a 3D structure based on the initial camera pose and performing correction so as to minimize a reprojection error of the reconstructed 3D structure.

Abstract: Disclosed is a device which includes a data manager, a learner, and a predictor. The data manager generates output data based on time-series data, receives device prediction results corresponding to the output data from the prediction devices, and calculates device errors based on the difference between device prediction results and time-series data. The learner may adjust a parameter group of a prediction model for generating device weights, based on device prediction results and device errors. The predictor generates the ensemble result of first and second device prediction results based on device weights.
