METHOD AND APPARATUS FOR PROJECTION OF BIM INFORMATION

摘要

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.

主权项

1. A system for projecting an image including layout information on a surface in a building under construction, comprising:
a moveable support for supporting a worker at a work position in a building under construction; a projector, mounted on said moveable support for projecting said image on said surface in response to an image signal defining the image to be projected, said image to be projected indicating a location of connectors, anchors, and holes to be affixed to, or cut through, said surface, wherein said surface is positioned above said moveable support; a positioning system for determining a two dimensional position and an orientation of said projector in said building; a distance measuring system for determining a distance from said projector to said surface; a memory in which is stored building plan images for said building; and a processor, responsive to said memory, to said distance measuring system, and to said positioning system for determining said two dimensional position of said projector, for providing said image signal to said projector that is adjusted for said two dimensional position of said projector and for said distance from said projector to said surface.
