A method of stripe gray-scale asymmetry adjustment for strip center extraction is proposed to solve the problem that stripe gray-scale asymmetric distribution degrades the accuracy of stripe center extraction in the structured light measurement.Firstly,the exponentiation of initial gray-scale is obtained.The initial gray-scale is subtracted from exponential calculation result,and the subtraction result is gray-compensated.Then,the gray-scale after compensation is used to iterate until the iteration terminat...
