Abstract: Traditional vision-based measurement techniques perform poorly on transparent glass surfaces, while tactile sensing is constrained by low sampling eficiency and limited resolution,impeding high-precision surface reconstruction.To address these limitations,a vision-tactile fusion measurement method is presented, integrating phase-measuring deflectometry with active tactile sensing. The vision subsystem supplies relative surface phase-gradient information, whereas the tactile subsystem provides absolute positional measurements;this combination resolves the gradient-height ambiguity and suppresses ghost-fringe artefacts produced by light deflection at the lower glass surface.An experimental setup comprising a Realsense D435 depth camera and a UR1O robotic arm was implemented and evaluated on planar and nearplanar glass specimens. Results demonstrate that the proposed method enables accurate perception and reconstruction of both planar and near-planar transparent glass surfaces.Relative to a depth-camera approach augmented by a developer agent, the proposed method reduced RMS error by 80.59% )for concave surface reconstruction and by ( 96.33% ) for convex surface reconstruction. The approach exploits the robot's inherent vision-tactile capabilities to achieve three-dimensional measurement and localizationof transparent glass,offering a practical solution for robotic perception and reconstruction of transparent surfaces.
