KANG Yan-hui, ZHANG Heng. Large free-form surface measurement system based on laser line-scan sensor[J]. 2012, 31(12): 79-82. DOI: 10.13873/j.1000-97872012.12.028.
The measurement of large free-form surface is of great importance for reverse engineering and product quality inspection.Based on laser line-scan sensor and arm of industry robot which can move in large range
a non-contact high efficiency measurement method is proposed.The principle and structure of measurement system is introduced
and data processing technique of free-form surface
especially the point cloud registration is studied.The experimental results show that this measurement system can realize a high precise measurement
and can achieve a satisfied effect for the measurement of large free-form surface.
