Patent number: 6969836Abstract: A method of determining the leading edge (E) of a turbine blade or airfoil (P). The object is mounted in a desired position and backlit using a light source (S). The object and its leading edge are viewed using one or more cameras (I) which are positioned on the opposite side of the part. When illuminated, the object blocks a portion of the light from the source and the occluded portion of the light defines an outline (T) of the object including its leading edge. An image of the object is obtained and the part is then moved to other positions at which additional images are obtained. The images are processed using a space carving algorithm to ascertain the contour of the leading edge of the object. This allows accurate measurements of the leading edge to be made for using in determining acceptability of the part.Type: GrantFiled: October 25, 2002Date of Patent: November 29, 2005Assignee: General Electric CompanyInventors: Geoffrey Mark Cross, Peter Henry Tu

Patent number: 6876459Abstract: Apparatus (10) for determining the leading edge (E) of an airfoil (A) includes a first light source (S1) illuminating a portion of the airfoil including its leading edge and a first camera (M1) acquiring an image of the illuminated portion of the airfoil. A second light source (S2), spaced apart from the first light source, also illuminates a portion of the airfoil including its leading edge. A second camera (M2) acquires an image of the portion of the airfoil illuminated by the second light source. The location (N2) of the second light source and the first camera are coincident in space as are the location (N1) of the first light source and the second camera. An image processor (P) processes the respective images obtained from the two cameras to locate the leading edge of the object. In doing so, the processor utilizes similarities in illumination of the airfoil by the respective light sources and occlusion boundaries of the respective illuminated portions of the airfoil.Type: GrantFiled: April 1, 2002Date of Patent: April 5, 2005Assignee: General Electric CompanyInventors: Peter Henry Tu, Glen William Brooksby, James Vradenburg Miller, Donald Wagner Hamilton
