ABSTRACT:
A method and apparatus for measuring an opening defined within object using an optical sensor system is provided. The method includes positioning an illumination source adjacent the opening, illuminating a perimeter circumscribing the opening, receiving an image of the illuminated boundary, and calculating an area within the received boundary. The system includes a light source oriented to project a first sheet of light intersected by a first portion of the opening perimeter, the light source projecting a second sheet of light intersected by a second portion of the opening perimeter, a light detector receiving a portion of the sheet of light intersected by the object opening perimeter and reflected toward the light detector, and an image processor communicatively coupled to the light detector, the image processor programmed to sample an image from the detector and programmed determine the dimensions of the object opening from the sampled image.
