Method and system for image processing for profiling with uncoded structured light

A 3D scanning apparatus configured to image a physical entity, said apparatus comprising:

• a radiation projector for projecting a plurality of radiation stripes onto said physical entity;
• a detector for detecting said striped radiation received from said physical entity;
• and
• a data storage device for storing said received radiation as a pixellated bitmap image comprising a plurality of rows;
• said apparatus characterised in that said physical entity, said radiation projector and said detector are geometrically arranged to constrain the number of times that each said received stripe is permitted to occur in a pixel row of said bitmap.
