We improve and adjust usual weak calibration techniques to the case of stereo video microscopes : Harris detector using a simplex optimization method to feature points detection, a "cha" window based ZNSSD correlation for points matching. Images of a pattern made with a water drop covered with nickel fillings are used. The result is validated by constructing 3D view of a micromanipulation work field.
