A study on a 3-D profilemeter using dynamic shape reconstruction with adaptive pattern clustering of the line-shaped laser light

One of the main problems in machine vision inspection systems that use the triangulation of line-shaped laser light is finding the exact laser light center positions. We describe a 3-D surface profilometer that improves the measurement efficiency. Reflection light intensity from a line-shaped laser light on the object surface is different from the colors and shapes of objects. The proposed 3-D surface profilometer can measure a 3-D surface shape remotely with enhanced measurement resolution than the conventional optical systems by using the dynamic shape reconstruction with adaptive pattern clustering of the line-shaped laser light. This proposed 3-D profilometer can be easily applied to practical situations involving 3-D surface shape measurements by extracting the exact center positions of the line-shaped laser light and compact hardware compositions.
