Design of Dynamic Focusing Unit for 3d Laser Scanner
نویسندگان
چکیده
The goal of design is to expedite the movement of the dynamic focusing unit which can increase the scanning speed, area, and accuracy simultaneously. Figure 2 shows that the design of a proposed dynamic focusing unit with using Voice Coil Motor (VCM). The focusing lens is fixed on the yoke and the moving lens is mounted on the bobbin and is moving when the VCM working. The focused spot is moved in the range of VCM. For this reason, the lens system has to have large optical levering and the efficient VCM design is required. FIGURE 2. Elements of dynamic focusing unit

متن کاملMapping and Localization in 3D Environments Using a 2D Laser Scanner and a Stereo Camera
2D laser scanners have been widely used for accomplishing a number of challenging AI and robotics tasks such as mapping of large environments and localization in highly dynamic environments. However, using only one 2D laser scanner could be insufficient and less reliable for accomplishing tasks in 3D environments. The problem could be solved using multiple 2D laser scanners or a 3D laser scanne...
