Gamma Precorrection and Phase Error Compensation Methods Based on Three-Frequency with Three-Phase Shift
Digital fringe projection measurement technology has been widely used in computer vision and optical three-dimensional (3D) measurement. Considering the phase error caused by the gamma distortion and nonlinear error, the active gamma precorrection and phase error compensation methods based on the th...
