摘要： A 3D object modeling system and method system and method captures a 2D representation of the object to be modeled and breaks the 2D image into its geometric elements. The 3D stereoscopic image is then fitted to the geometric elements generated from the 2D image to generate the final model. The 3D stereoscopic image may be compared with the geometric elements to detect distortions in the object, allowing the distortions to be corrected in the final model to ensure that the model accurately depicts the original object.

摘要： Provided are methods for accurately measuring nozzle 50 flow areas of new or refurbished gas turbine engine vanes 14. A first vane 114 is suitably fixtured in a laser scanning system 60 comprising a laser spot projector 82 a laser spot sensor 84, a multi-axis controller 68 and a computer 78. According to a nozzle flow area measurement method, a convex surface 38 and a concave surface 40 of a first vane 114 are scanned and stored as point clouds 196, 296 with the system. The point clouds 196, 296 are combined into a point cloud 396 and translated to a reference coordinate system 98. A point cloud 496 representing a nominally sized, second vane 214 is positioned adjacent to one surface of the combined point cloud 396. An inlet profile 56 is extracted from the intersection of an inlet plane 58, perpendicular to a combustion gas flow vector 18 direction, and each point cloud 396, 496. A nozzle 50 flow area is then accurately calculated using integration techniques from the inlet profile 56. The process is repeated for the second surface of the first vane 114. In another method, a combined point cloud 396 of a second vane 214, which is also scanned using the scanning system, replaces the nominal point cloud 496. The nozzle 50 flow area between the first 114 and second 214 vanes is then measured using the earlier described method steps.
