“…(2) When the encoded triangular fringe pattern is projected onto the surface of the test object, the proposed method then generates an intensity ratio by evaluating the three independent deformed fringe patterns (red, green and blue) simultaneously detected by a three-chip CCD. Although a similar method was preliminarily proposed to generate a slit code [21], the developed method is the first that employs the simultaneously encoded triangular fringe pattern to achieve real-time 3D surface profilometry.…”

In this paper, a novel active structured fringe method for dynamic 3D surface profilometry is presented using a colour fringe pattern encoded with multiple phase-shifted triangular modulations. Rapid 3D surface profilometry is extremely important to automatic optical inspection (AOI), especially for in situ optical surface profilometry. In the proposed approach, three-step phase shifting can be simultaneously performed by encoding and analyzing components of red, green and blue colours in the projected colour fringe patterns. A significant advantage can be obtained in eliminating arctangent calculation and one-shot imaging for obtaining dynamic full-field 3D surface profile reconstruction. Experimental tests were conducted to verify the capability of the developed method in achieving high-speed 3D measurement with an average measurement error of less than 2.8% of the overall detection range.
