The basic principle of the 3D vision inspection based on circle structured light is firstly introduced. To the inner surface of micro-miniature workpiece, the scheme to measure the inner surface is presented based on circle structured light. The mathematic model of 3D vision inspection based on circle structured light is established successfully using camera's pin-hole model and coordinate transformation,and the parameters of the mathematic model are also optimized. The simulation result shows that the model resolution is 3μm is case of the measurement of the inner surface with a 5～15mm dimension.
