【摘要】 将MATLAB的数值计算及图形功能,用于模拟装满水的玻璃杯上凸显唯一明亮清晰指纹的现象,通过模拟图像分析了指纹成像的"明亮清晰性"和"唯一性"问题.分别讨论了指纹到水面的距离,玻璃杯的厚度等因素对该现象的影响,并且运用MATLAB进行最小二乘法拟合,建立了指纹到水面距离与出射光线到玻璃杯外壁距离的线性函数关系.更多还原

【Abstract】 The numerical and graphical functions of MATLAB language are used in the simulation of the only bright and clear fingerprints displayed on the wall of a glass filled with water.The "bright-clear" and "only" of the fingerprints are analyzed via the simulated images.The effects of the distance from the fingerprints to water surface and the thickness of the glass are discussed,and the least squares method is used to fit function by using MATLAB.The linear function relationship between the distance from the fingerprints to water surface and the outgoing light to the glass-lined wall is established.更多还原
