机器视觉系统中确定散射光量的方法和设备

Method and apparatus for determining the amount of scattered light in a machine vision system

Abstract

本发明涉及在机器视觉系统中确定在物体中散射的光量的方法和设备,该机器视觉系统包含:利用沿着至少一个方向有限延伸的入射光照射所述物体的光源;和检测从所述物体发出的光的成像传感器,其中,所述发出的光是所述物体的表面上的反射光(R)和在所述物体中散射的光(S),所述检测到的光在所述成像传感器上形成含有峰值的至少一条强度分布曲线,其中在所述峰值处在所述成像传感器上检测到所述反射光(R)。测量围绕所述峰值的所述至少一条强度分布曲线的宽度(w),从而所述测量到的宽度(w)指示在所述物体中散射的光(S)的量。
The present invention relates to a method and an apparatus for determining the amount of light scattered in an object in a machine vision system comprising: a light source illuminating said object with incident light having a limited extension in at least one direction; and, an imaging sensor detecting light emanating from said object, wherein said emanated light is reflected light (R) on the surface of said object and light scattered (S) in said object, said detected light is resulting in at least one intensity distribution curve on said imaging sensor having a peak where said reflected light(R) is detected on said imaging sensor. A width (w) of said at least one intensity distribution curve around said peak is measured, whereby said measured width (w) indicates the amount of light scattered (S) in said object.
