  With the rapid development of computer graphics and vision, several
three-dimensional (3D) reconstruction techniques have been proposed and used to
obtain the 3D representation of objects in the form of point cloud models, mesh
models, and geometric models. The cost of 3D reconstruction is declining due to
the maturing of this technology, however, the inexpensive 3D reconstruction
scanners on the market may not be able to generate a clear point cloud model as
expected. This study systematically reviews some basic types of 3D
reconstruction technology and introduces an easy implementation using a linear
laser scanner, a camera, and a turntable. The implementation is based on the
monovision with laser and has tested several objects like wiki and mug. The
accuracy and resolution of the point cloud result are quite satisfying. It
turns out everyone can build such a 3D reconstruction system with appropriate
procedures.
