Abstract: In order to use the general-purpose camera for stereo vision, the correction for distortion is needed. In this study, a new technology to achieve the distortion correction is proposed. The proposed method is based on block matching method. In the proposed method, global and local estimations for two reference images are carried out and two vector maps which are used for estimating corresponding points are obtained. In this study, a new correction technology to need for acquisition depth information using the general-purpose camera is suggested. This is an extended research of the previous research. The proposed technique firstly obtains the vector map based on the block matching technology for solving the lens distortion and the distortion correction is achieved using the vector map. The proposed method is useful for simplified 3D information extraction than precise processing.
