Color structure-light stripe center-line extraction method research

摘要

As a kind of active measurement and 3D reconstruction method, 3D visual technology based on coding structured light gets more and more attention. Color stripe structure light method can quickly and accurately obtain information of the surface of 3D object model, and fringe image processing is one of its key technologies. Due to the influence of external environment, collecting the modulated structured light in subsequent process will have great difficulties. This article proposed image enhancement based on Retinex after fringe processing method, and studied the coding structured light stripe image enhancement method and corresponding coding structured light stripe images center-line extraction. Experiments show that, the extracted coded structured light stripe center lines of single pixel level is high, middle and high, strong adaptability, and has simple processing method, so as to provide convenience for further obtaining the model surface point cloud data.
