Laser rangefinder can accurately acquire environment information by using laser distance measuring technology. So it attracts a lot of attention in robot navigation, localization, obstacle avoidance and path planning. But dues to its high cost of several thousands of dollars, laser rangefinder can not be introduced widely to researchers. In this paper, research on fake laser rangefinder based on inexpensive...
A low-cost and portable three-dimensional scanner system is designed in this paper, including hardware and software systems. A common camera and a linear laser emitter are used to detect the distance of the object by using triangulation algorithm. Meanwhile, 3D point cloud data is generated. Then by using QuickHull algorithm or MeshLab software, the object's surface can be recovered. To verify the...
