Abstract

Fringe Projection Profiler (FPP) is one of the most popular optical non-contact three-dimensional (3D) shape measurement technologies and a research hotspot in 3D face recognition. However, due to the use of a digital light projector (DLP), high-speed, low-cost, and small-size face measurement is still a big challenge. In this article, we developed a high-speed 3D face measurement system based on near-infrared, and proposed using a projection module to replace DLP for projection. Through the accuracy experiment, the measurement accuracy of this system is better than 0.15mm. Experiments on real faces show that this method can collect 3D face data at a lower cost and at a higher speed, and meet the requirements of the field of 3D face recognition.
