Embodiment Construction

[0041] Figure 1 to Figure 3 The building 11 is shown under construction and helps illustrate various embodiments of the invention. Each floor of building 11 is an interior construction site where various building structures, components and fixtures must be located. When laying out the interior of each floor, it is necessary to locate a large number of construction points where individual operations or building components are to be positioned and installed. Power tools and hand tools are used to install fasteners, nails, and similar devices, and to cut and drill various structural components, such as ceilings and walls on each floor of a building. These operations are performed at predetermined construction points.

[0042] Figure 1 to Figure 3 The overall system shown utilizes a pico projector 13 to project an image 14 including layout information onto a ceiling or other surface of a building 11 . The movable support may comprise a scissor lift 17 for supporting a worker...

Abstract

A system for projecting an image, including layout information, on a surface in a building under construction has a projector mounted on a moveable support for supporting a worker at a work position in the building. The projector projects an image on a surface above the moveable support in response to an image signal defining the image to be projected. The image indicates the location of connectors, anchors, and holes to be affixed to, or cut through, the surface. A system determines the two dimensional position of the projector in the building, and a distance measuring system for determines the distance from the projector to said surface. A processor, responsive to a memory having stored building plan images, provides an image signal to the projector adjusted for the two dimensional location of the projector and for the distance from the projector to the surface.

Description

[0001] Cross References to Related Applications [0002] This application is related to and claims priority to US Nonprovisional Patent Application Serial No. 13 / 800,828, filed March 13, 2013, which is hereby incorporated by reference in its entirety. [0003] Statement Regarding Federally Sponsored Research or Development [0004] Not applicable Background technique [0005] During a building construction project, such as the construction phase inside a large new building under construction, or during the renovation of an old building, it is useful to refer to Building Information Modeling (BIM) data. This data, when available, defines the three-dimensional building structure, including the interior, and its use increases the productivity of construction workers by facilitating the positioning and placement of various building construction elements and fixtures. Typically, a BIM model of a building is maintained after building construction is completed, and this model ca...
