changes and surface irregularities.
In this relatively simple application, a single line
projection spans the diameter of the clutch plate as it
is rotated. Triangulation of the red line image then
provides a high resolution scan of the entire plate.

…produces a line of
illumination that appears distorted from perspectives
other than that of the projector. These distorted
perspectives can be used for an exact geometric
reconstruction of the surface shape.
In a typical 3D triangulation sensor, the laser line
provides…

…given spot diameter or line thickness.
Laser vision is also used to check the alignment of wheel and tire during
mounting on to cars on the production line, e.g., relative to the steering
mechanism. Here the laser module projects a pattern of parallel lines on to
the front…

…But there are many different ways to implement a laser line projection system. Each has its own characteristics, advantages and disadvantages. In triangulation (Figure 1), a laser line is projected onto a part, and a camera views the line and analyzes its shape dynamically to reconstruct…

…common, laser triangulation architecture is the single straight line
projection geometry. Here, simple optics fan out the laser beam so that it forms a straight line of
illumination on the part. When viewed by a camera from an angle different from the projector, the line is
distorted…
