Recently, the 3D sensing technique using plural cameras has been applied to various areas such as visualization, motion capturing, and so on. However, improvement of the camera model calibration is indispensible for more precise measurement. In this study, we propose a fuzzy modeling approach for 3D sensing utilizing the configuration of the stereo vision. A distance between a sensing target and the camera and a distance of an image pixel from the optical axis are used for structuring the fuzzy model for cameras. In our approach, the weighted least mean square error method is successfully applied considering fuzzy partition to formulate the fuzzy model. Through sensing experiments based on the proposed approach, we show effectiveness of the approach in terms of sensing precision.

In the computer vision approach, there are many problems of modeling to prevent affections of noises by sensing units such as cameras and projectors. In order to improve the performance of the modeling in the computer vision, it is necessary to develop a robust modeling technique for various functions. The RANSAC algorithm and LMedS algorithm have been widely applied for such issues. However, the performance is deteriorated when the ratio of noises increases. Moreover the computational time for the algorithms tends to increase for actual applications. In this study, a new fuzzy RANSAC algorithm based on the reinforcement learning concept is proposed for homography estimation. The performance of the algorithm is evaluated through experiments of camera homography. From the results, the method is found to be effective to improve calculation time, optimality of the model, and robustness in terms of modeling performance.
