Abstract
An aerial image projection system is provided for use on an airship, balloon, or other inflatable structure which obtains its lift from gas or hot air, and may be used for advertising or other video projection and display. A defined surface area of the envelope of the inflatable structure serves as the projection screen for receiving a video image effective for viewing from a location external to the inflatable structure. A projector apparatus is mounted to the exterior framework or envelope opposite the projection screen for projecting a video image through a window in the envelope and through the interior of the inflatable structure to the opposing projection screen. The projector apparatus utilizes a projector array for establishing the required illumination for viewing long distances.
Claims21
An image projection system for use on an inflatable structure, comprising:
- a flexible material forming an inflatable volume having a predetermined surface area which defines a projection screen for receiving a video image effective for viewing from a location external to the inflatable structure, and having a transparent window formed in said flexible material on a surface of said inflatable volume opposing said projection screen;
- and
- a projection apparatus aligned to the exterior of said transparent window for projecting a video image through said inflatable volume and onto said projection screen.
An image projection system for use on an airship structure, comprising:
- an airship hull having a predetermined surface area which defines a projection screen for receiving a video image effective for viewing from a location external to the airship structure;
- and,
- a projection apparatus mounted to an opposing surface of said hull for projecting a video image through the interior of said airship and onto said projection screen.
An aerial image projection system for use on a balloon structure, comprising:
- a flexible material forming an inflatable volume having a predetermined surface area which defines a projection screen for receiving a video image effective for viewing from a location external to the balloon, and having a transparent window formed in said flexible material on a surface of said inflatable volume opposing said projection screen;
- and
- a projection apparatus aligned to the exterior of said transparent window for projecting a video image through said inflatable volume and onto said projection screen.
