Shape-Adjustable Chroma Key Compatible Mannequin or Body Suit, and Associated 3D Image Capture Equipment

Abstract

A body suit resembles at least a partial human body form for use in design, customization, alteration, testing and modeling of garments. The suit includes a plurality of fluid-expandable layers, including an outer skin layer divided into an outer plurality of selectively expandable in varying degrees or quantities to create a variable exterior skin contour. One or more additional fluid-expandable layers underlie the outer skin layer to establish a variable internal tissue depth further contributing to an overall outer body contour of the body suit. An exterior of the body suit is colored or colorable in blue or green to enable chroma key isolation of garment adorned over the suit. Sensors are arrayed over the exterior surface area of the suit for dimensional and pressure measurements, and rotational support structures and cooperating 3D scanners and track-based scanner movement enable 3D imaging of the modeled garment.
