The resolution measurement model of three-dimensional integral imaging display system is established, and the shape, scale and fringe width of the model are designed. The model can be used to measure the reconstructed depth of field and field angle of integral imaging display system. First, the parallax map is obtained by taking the test model from multiple angles according to the integral imaging technology. Then, the parallax image definition line is calibrated according to the method of the two-dimensional resolution test card. Finally, the composite image calculated by parallax images is loaded onto the integral imaging system and the the resolution of three-dimensional objects reconstructed by the system can be tested. Experimental results show that this design supports the observer to test the display resolution in different angles and depths, and quantifies the resolution of the integral imaging display system. The model contains 8-level resolution definition line, which basically meets the test range of current three-dimensional display system resolution and can be used to measure the reconstructed depth of field and field angle of integral imaging display system.
