Title
Dimension Measurement Of Objects With Circular Cross Section Using Point Light Sources And An Image Sensor Without Lens
Abstract
Common optical methods for dimension measurement apply an image sensor with a lens. The presence of the lens in the camera (and sometimes in the employed illuminator as well) increases the total dimensions of the measuring setup. Furthermore, the aberrations of the lens represent a source of uncertainty. In order to simplify the measuring setup and to reduce its overall dimensions, the method proposed in this paper applies a measuring setup that contains no lens-it employs an image sensor without a lens and two point light sources that illuminate the measured object. In this paper, the application of this method for dimension measurement of objects with a circular cross section is described. In addition, several issues related to the method's implementation are discussed, and its performance is illustrated using experimental results.
