| 英文摘要 | a portable 3d laser scanning system has been designed and built for robot vision. by tilting the charge coupled device (ccd) plane of portable 3d scanning system according to the scheimpflug condition, the depth-of-view is successfully extended from less than 40 to 100 mm. based on the tilted camera model, the traditional two-step camera calibration method is modified by introducing the angle factor. meanwhile, a novel segmental calibration approach, i.e., dividing the whole work range into two parts and calibrating, respectively, with corresponding system parameters, is proposed to effectively improve the measurement accuracy of the large depth-of-view 3d laser scanner. in the process of 3d reconstruction, different calibration parameters are used to transform the 2d coordinates into 3d coordinates according to the different positions of the image in the ccd plane, and the measurement accuracy of 60 mu m is obtained experimentally. finally, the experiment of scanning a lamina by the large depth-of-view portable 3d laser scanner used by an industrial robot irb 4400 is also employed to demonstrate the effectiveness and high measurement accuracy of our scanning system.
