Non-contact coordinate measuring had been performed high efficiency measurement by wide area scanning, but the measurement error was increased by the influence of surface properties and optical characteristics. Here, Relation between optical characteristics and surface roughness were studied in order to determinate measurement error based on optical characteristics of workpiece surface. As a result, it is suitable for index of evaluation that Rz (JIS), R3z as roughness average present and Rdc as bearing ratio curve present was represented for scattering of surface.
