摘要：This paper reviews the state-of-the-art real-time three-dimensional shape measurement techniques that are capable of reconstructing the dynamic objects. In this review paper, we only concern the real-time data acquisition ability and the measurement accuracy since the real-time processing and displaying ability relies on the supporting hardware and the adopted fast algorithms instead of the measurement schemes. Based on their working principles, we divide the reviewed real-time three-dimensional shape measurement techniques into three classes: structured light, stereo vision and time of flight. Almost all the reviewed techniques use one-shot measurement scheme and thus not affected by the motion-caused vibration noises. Many measurement techniques have generated quite a lot widely-used commercial products while other measurement techniques still have a long way to go before they become mature for commercial usage. We compare the advantages and disadvantages of these techniques extensively, analyze their limitations and discuss their prospects. (C) 2020 Elsevier Ltd. All rights reserved.
