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. |

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 the moveable support, for projecting an image on a surface above the moveable support in response to an image signal defining the image to be projected, said image indicating the location of connectors, anchors, and holes to be affixed to, or cut through, said surface, a system for determining the two dimensional position and orientation of the projector in the building, a distance measuring system for determining the distance from said projector to said surface, a memory in which is stored building plan images for the building, and a processor, responsive to said memory, to said distance measuring system, and to said system for determining the two dimensional position of the projector, for providing an image signal to said projector adjusted for the two dimensional location of said projector and for the distance from said projector to said surface. |
