顕微鏡視野における輪郭ボケ幅による奥行距離推定モデルとその安定性評価

Recent growth of a microscope and micromanipulators have been remarkable. With the growth, micro-manipulation in the micro world (less than dozens of micro-order) is significant in a variety of fields. However, 3D-estimation in microscopic view is difficult. We have developed a high-precision depth estimation method based on difference between blur widths of a particle and a tip of micromanipulator in our previous study. In our proposed method, one shot microscopic image can estimate precisely a depth distance without lens parameters. However, our method has a problem of a derivation of the depth equation. We propose a technique to derivate the equation using by Robust estimation and Mahalanobis' distance. To confirm stability and precision of the proposed technique, we show the validity through experimented results.
