Abstract: This paper describes an approach to depth detection in scanning electron microscope images which aims at the automation of nanohandling procedures. It incorporates simultaneous tracking of an object in a stereo image pair, generated using a self-built magnetic lens for tilting the electron beam. Object depth is concluded from the object displacement. The tracking procedure is based on the active contours method, adjusted by a region based energy function. An automatic contour initialization is presented that makes use of edge detection. All methods described have been implemented and tested extensively in the designated automation environment. The approach is found to provide very accurate depth estimates even at a small level of magnification.
