浙江大学硕士学位论文 Abstract Abstract ln the recent years，the technology and system of Multi-projector display develop rapidly. When the Geometry Calibration develops ωa mature case，the technology of Color Calibration determines the quality of Multi平rojector system. η1ís paper begin with the theory and the Attribute of CI巳XYZ color space，and compare the advantages and disadvantages especially in Color Calibration and Multi-Projector sys阳m among 由e LCD Projector，DLP Projector，η町即-DMD DLP Projector. Then，we get the concepts of lntrinsic Curve for Projectors. Besides，we configure the way and algorithm to measure the lntrinsic Curve. ln the technology of Color Calibration ，we inherit the Color Calibration based on the brightness Consistency; develop the technology of Color Calibration to the direction of the Color Optimization. Then we improve the Color Calibration based on Perceptual Consistency，in addition to ensure the Luminance smooth morphing our algorithm achieves the Chrominance smooth morphing and 由e uniform of white balance. Based on our algorithm ，we implement the Multi-Projector system which is scalable and flexible.η1ís system can give di的rent plan according to different demand and can be adjusted real time. Besides ，we develop the B-Spline Calibration library to improve the efficiency of Color Calibration. Finally，this paper analyzes the e付。rs in the process of Color Calibration，and then summarizes the general workflow of Color Calibration including the Projector selection and hardware a司justmen t.
