Spatial symmetric multi-level coding absolute phase retrieval for color 3D real-time measurement

•A symmetric multi-level coding based temporal phase unwrapping is proposed.•Only one auxiliary coding pattern is used for 3D color real-time measurement.•Proposed temporal phase unwrapping method can enhance robustness, fault tolerance and reconstruction accuracy.•Proposed new projection strategy b...
