The invention relates to a general system and a method for extracting irregular cambered surface edges. The system comprises an area-array camera, a lens, an annular light source, an annular light source controller, a control computer and a detection object fixing platform, wherein the lens is located above the support platform structure and vertically faces a tested sample; the area-array camerais used for being connected with the lens; the annular light source is located between the lens and the tested sample and is used for irradiating the tested sample; the annular light source controlleris electrically connected with the annular light source and the control computer; the control computer is electrically connected with the area-array camera and the annular light source controller; the control computer is used for obtaining image data, analyzing image extraction edges, converting the image extraction edges into spline curves, and saving the spline curves in a file format recognizable by 3D modeling softwar
