ABSTRACT:
An apparatus for determining the dimensions of an object such as a person uses a video or diskette or still camera, and includes further two projectors for projecting a horizontal raster line pattern at a 45.degree. angle onto the person, so that projected lines as imaged appear in superimposed relation to the person also as imaged; there is an improvement which includes a horizontal overhead mirror or a pair of horizontally positioned overhead concave mirrors, the projectors being oriented so that the raster as projected is directed towards the mirror(s) at a 45.degree. angle to that mirror, so that the projection beam is reflected at a 45.degree. angle accordingly.
