Abstract: This paper presents a novel single camera light-field three-dimensional pressure measurement technique (LF-3DPSP), which consists of light field 3D reconstruction and pressure sensitive paint. The technique uses a light-field camera to capture the wind-on, wind-off and model geometry images, which has a similar experimental procedure as the traditional 2D PSP method. The proposed technique was validated with a Ma5 truncated cone model test. The results show that LF-3DPSP is capable of measuring the surface pressure distribution on relatively large curvature 3D models with high accuracy, and the pressure results agree favourably with those of the schlieren test.
