英文摘要： The research of three-dimensional measuring and modeling for the large thin-wall objects with high accuracy and high density has great academic value for the theory and technique and broad application prospect in the engineering. In our project, we will implement the 3D measuring and modeling for the large thin-wall objects by constructing an optical measurement network with multiple 3-D sensors. Meanwhile, the key issues for the multi-sensors network measurement are proposed including: (1) the network planning with multi-sensors, (2) the construction of calibration reference in large scale volume, (3) the global calibration of the sensors in the network, (4) the registration and integration of the range data measured by the multi-sensors network, (5) the measurement error analysis and compensation in the measuring network. With the research of this project, it can not only extend the content of 3D digital imaging and modeling extremely, but also produce widespread application value in engineering inspection for the large-scale thin-wall objects, such as large quartz crucible, oil tank, automobile panel, etc.
