Large Area Of The Development Of The Diffuse Reflection And Projection Of The Grid Geometry Correction

The large area of diffuse reflection screen is mainly used in the target position of field remote sensing experiments and ground simulation of space environment.It has a wide range of applications in the field of laser-guided weapon simulation systems, Space remote sensing experiment, calibration of the spectrometer.In this paper,We develop the first large area of diffuse reflection screen and complete the design of the mechanical structure.It Successfully put into use in the laboratory lighting scene simulation system.According to the requirements of the project system,The grid projection need display in the diffuse reflection screen for the high-speed camera positioning.This article describes a grid distortion correct method.The method uses a computer, a digital camera and a projector to correct the distortion which is caused by the projector’s position.Using Matlab simulation to output the corrected graphic file.The image is displayed in the diffuse reflection which has no distortion of the grid projection.This experiment shows that the method has a high accuracy and can realize distortion correction effectively.
