This paper considers the problem of positioning an eye-in-hand system so that it gets parallel to a planar object. Our approach to this problem is based on linking to the camera a structured light emitter designed to produce a suitable set of visual features. The aim of using structured light is not only for simplifying the image processing and allowing low-textured objects to be considered, but also for producing a control scheme with nice properties like decoupling, stability and adequate camera trajectory. This paper focuses on an image-based approach that achieves decoupling in all the workspace and for which the global asymptotic stability is ensured in perfect conditions. The behavior of the image-based approach is shown to be partially equivalent to a 3D visual servoing scheme but with a better robustness with respect to image noise. Concerning the robustness of the approach against calibration errors, it is demonstrated both analytically and experimentally
