摘要
为了分析机器视觉测量系统中LED阵列对柱面底板照度的影响因子,采用Taguchi实验方法设计实验,对环形、方形、菱形LED阵列不同接收面半径、发光半角、发光面与接收面的距离因素进行分析。结果表明:利用Taguchi方法可以很快地找出辐照均匀度较大和最大的照度值,单颗LED的发光半角对辐照均匀度及最大照度的影响最大,分别占有66.18%和63.10%的影响地位。单颗LED的发光半角越大,其阵列的辐照均匀度越高,单颗LED的发光半角越小,其阵列光线比较汇聚,阵列最大照度值更大。
In order to analyze the influence factor of LED array on the illumination of cylindrical floor in machine vision measurement system,the Taguchi experimental method is adopted to design the experiment,the distance factors of different receiving surface radius,illuminating half angle,illuminating surface and receiving surface of annular,square and diamond LED arrays are analyzed.The results show that the Taguchi method can quickly find the illumination uniformity and the maximum illumination value.The half angle of single LED has the greatest influence on the uniformity of irradiation and the maximum illumination,accounting for 66.18%and 63.10%respectively.The larger the half angle of illumination of a single LED,the higher the uniformity of array radiation.The smaller the half angle of illumination of a single LED,the more concentrated array light,and the larger the maximum array illumination value.
