Paper Abstract

To measure the shape of object with high-speed and avoid the disturbance of the vibration is remaining challenges faced by structured-light projection method. This paper proposes a high-speed optical metrology by coding three cosine patterns into three channels of RGB model to form the pattern. When the color image is obtained by camera, it will be transformed to HSI color model (hue, saturation and intensity). The hue component is regarded as the phase information to retrieve the 3D shape of object with single image, while the saturation and intensity are applied to avoiding phase errors caused by height steps or spatially isolated surfaces. This method can be used to measure object with non-monochromatic surfaces after the color compensated. Experimental results verify the feasibility of the developed method.
