Abstract：This paper presents a stereoscopic display method for calculation of light field based on orthogonal projection. The method is used for the display of continuous parallax,smooth view and crosstalk elimination. This display method collects and records elemental image array of the light field directions and intensity, analyzes the elemental image array position corresponding to the amplitude distribution of information,renders 3D scene using computer based ray tracing methodology and collects 3D scene using orthogonal projection. It reorganizes the calculated light scene elemental image array through the sampled amplitude distribution information analysis. The core part of the display device has a cylindrical lens array and a 4 K display screen. The experiment results show that the calculated light field based on orthogonal projection reflects the correct relationship between the depth of the object and the occlusion and removes crosstalk.
