Improved High Dynamic Range for 3D Shape Measurement based on Saturation of the Coloured Fringe

Phase-shifting fringe projection methods have been developed for three-dimensional scanning (Zuo et al., 2018). However, the 3-Dimensional (3D) of objects with a high dynamic reflectivity range based on structured light is challenging task to achieve (Feng The incorrect intensities captured will cause phase and measurement errors. Thus, this paper proposes method that improves current High Dynamic Range (HDR) (Jiang 2016)) increase range. camera projector 3 channels, red, green, blue, which can absorb project these lights independently. This makes use by controlling intensity each projected camera. Each image be split into channels provide images contain different intensities, then it used compute 3D information. In general, done green blue (RGB) channel apply Jiang’s algorithm 2016). results are compared analysed HDR (Jiang’s method) regular three-step phase-shifting methods. From experimental results, has shown our proposed outperforms Specifically, manages reflective property objects. Additionally, also significantly reduced times object measurements.
