Low Z-height projection system for projecting structured light for 3D imaging

摘要

A low Z-height projection system includes a display panel for displaying a grating pattern that has gratings extended in a first direction. A projection lens system is also included and projects the grating pattern displayed on the display panel onto a surface. The projection lens system is a truncated circular lens system that has a first lens width in the first direction and a second lens width in a second direction. The first lens width is less than the second lens width. The first and second directions are orthogonal.

1. A low Z-height projection system comprising:
a display panel to display a grating pattern including gratings extended in a first direction; and a projection lens system through which the grating pattern displayed on the display panel is projected onto a surface, wherein the projection lens system is a truncated circular lens system having a projection lens, wherein the projection lens has a first lens width in the first direction, wherein the projection lens has a second lens width in a second direction, wherein the first lens width of the projection lens is less than the second lens width of the projection lens, and wherein the first and second directions are orthogonal.
