Fringe projection profilometry (FPP) has been widely used in various fields because of its advantages noncontact, nondestructive, high precision, and speed. However, due to the subsurface scattering effect, FPP encounters severe challenges when performing 3-D measurements translucent objects. Based on FPP, this article proposes a novel measurement method for objects using periodic line-fringe patterns complementary Gray code patterns. By photographing set with different phases multi-Gaussian...
Camera calibration is critical for vision sensors. In a scene where the target easily occluded, it usually difficult traditional methods to obtain satisfactory results. This article proposes novel camera method based on freely placed right cylinder (RC), which has strong adaptability scenes occluded. First, distortion coefficients of are obtained by using projection lines cylindrical quadric. Second, intrinsic and extrinsic parameters calibrated geometric properties RC vanishing point. Then,...
