Pattern Projection Process

The pattern projection process is a 3D measuring method. It necessitates at least one pattern projector and at least one camera.  The projector illuminates the target sequentially over time with patterns of light and dark parallel stripes with various widths. The camera, aligned at a known angle, records an image of each projection pattern. A time sequence of different brightness values is thus created for each of the camera’s pixels (pixel). The 3D point cloud is calculated from the different images.
