A method (400) and apparatus for measuring an opening (202) defined within object (38) using an optical sensor system (200) is provided. The method includes positioning (402) an illumination source (216) adjacent the opening, illuminating (404) a perimeter circumscribing the opening, sampling (406) an image of the illuminated boundary, and calculating (408) an area (213) within the received boundary. The system includes a light source (216) oriented to project a first sheet (220) of light intersected by a first portion (208) of the opening perimeter, the light source projecting a second sheet of light (222) intersected by a second portion (210) of the opening perimeter, a light detector (224) receiving a portion of the sheet of light intersected by the object opening perimeter and reflected toward the light detector, and an image processor (226) communicatively coupled to the light detector, the image processor programmed to sample an image from the detector and programmed to determine the dimensions of the object opening from the sampled image.
