A system and method for non-contact measurement of a complex part is provided. The method comprises acquiring an image of the complex part including imposed laser lines on the complex part using at least one imaging device, determining a span of interest of the complex part being representative of at least a portion of the complex part and which comprises information related to a plurality of dimensions of a surface of the complex part, extracting information corresponding to the laser lines from the span of interest to reduce computation and further extracting a plurality of unique points from the information corresponding to the laser lines, the plurality of unique points representing the plurality of dimensions of the surface. The plurality of unique points is used for reconstructing a three-dimensional (3D) representation of the surface of the complex part.
