Abstract
A system and method for measuring a height of objects on a moving surface comprising providing a linear image sensor positioned transverse to a direction of travel of the moving surface, and at least one light source positioned collinear to the linear image sensor and proximate to an edge of the moving surface so that the light source projects a unique patterned light sequence across a width of the moving surface, detecting a transverse shift in a portion of the unique patterned light sequence with respect to the direction of travel of the moving surface as an object passes through the unique patterned light sequence, determining an amount of shift of the portion of the unique patterned light sequence, and determining a height of the object based on the portion of the unique patterned light sequence shift.
