LASER COMPONENTS USA’s FLEXPOINT MVstereo laser module generates truly random patterns with 31,806 or 47,708 dots. Versions with 40,100 and 29,594 dots are now also available. Due to the different number of dots and the different fan angles of the patterns, users can choose the optimal optics for thir application. Both versions are available with red (660 nm) or NIR (830 nm) lasers, and both are eye safe (laser class 1 and 1M).
The FLEXPOINT MVstereo is designed for 3D stereo image processing, in which three-dimensional structures are calculated from the pixel information. One basic prerequisite for this method is that all the pixels of the two camera images be able to be clearly assigned during image comparison. However, this is only possible on unambiguously textured surfaces.
For smooth, monochrome structures, either markers or random patterns are used. The pattern generator of the MVstereo projects a randomly-arranged cloud of dots. Each dot can be assigned to a specific position. For more info, peruse the datasheet.
