    Abstract: System for an interactive projection system for adjusting projected images. The system includes a paired projector and camera, a workstation, and processor. The processor acquires an initial image of the surface via the camera and communicates information on the image to the workstation. A user creates a graphic at the workstation and manipulates the graphic to obtain a selected position, orientation, and/or scaling of a manipulated graphic. The manipulated graphic is projected by the projector onto the surface. The camera communicates an updated image of the surface, including the projected graphic, to the workstation.

  • Patent number: 10503059
    Abstract: The invention provides a system and method that reduces the precision of the manual alignment process. Users select correspondences between projectors or components of a projector, to form a common coordinate. Using models of the display system, and projectors, the common coordinate system can be mapped quickly to the entire display. The process avoids a need to measure screen points, and allows the user to move significantly fewer points. Alternatively, the invention allows introduction of machine-vision style algorithms into manual calibration techniques to improve performance. This overcomes the tediousness of prior systems by introducing models of the display into the manual alignment process, allowing selection of a small number of points on each projector, and avoiding selection of precisely measured screen points. The system conversely finds correspondences between projectors, allowing mapping of the projectors into a common coordinate system, and quick warping of the coordinate system to the screen.

  • Patent number: 9612516
    Abstract: A projection type image display apparatus (1) comprises a focus correction system (30). The system includes a temperature detection mechanism (16) for measuring temperature in the vicinity of a projection lens group (13), a correction amount calculation unit (18) for calculating a correction amount for correcting the focus shift caused by a temperature change, and a driving signal generation unit (19) for generating, based on the correction amount, a driving signal for driving a focus adjustment mechanism (15). If the user performs a focus adjustment using a focus operation input unit (23), a focus operation determination unit (21) determines that a focus adjustment has occurred independently of the focus correction system and changes a correction condition stored in a memory (20).

  • Patent number: 9596440
    Abstract: A scanning laser projector includes a proximity sensor and a planarity detector. When the proximity sensor detects an object closer than a proximity threshold, laser power is turned down. The scanning laser projector can measure distance at a plurality of projection points in the projector's field of view. If the projection points lie substantially in a plane, laser power may be turned back up.

    Abstract: A system includes a seeker having a reflective surface of rotation, an image detector configured to capture images of a field of view, and an imaging lens group configured to provide the images of the field of view from the reflective surface of rotation onto the image detector. The system also includes an electronics unit configured to process the captured images. The reflective surface of rotation could distort the field of view in the captured images, and the electronics unit could remove distortions in the captured images caused by the reflective surface of rotation. The electronics unit could remove the distortions in the captured images using inverse reflective anamorphosis. The reflective surface of rotation could include a concave surface, a convex surface, a cylindrical surface, an inverted straight cone, a slice of a sphere containing an outer curved surface, or at least one reflective surface rotatable around an optical axis.

  • Patent number: 9560329
    Abstract: The performance and the functionality of a projection-type video display device are improved to expand an application range of the projection-type video display device. The projection-type display device has two optical engines, increases the luminance of a display image, achieves a pseudo high resolution, or displays a three-dimensional image and a wide screen. The two optical engines have an adjusting mechanism to adjust a position on which an image is displayed. The adjusting mechanism has a plurality of mechanisms which adjust relative three-dimensional axis-direction positions between the two optical engines and inclinations of the optical engines with respect to axes. For example, in consideration of cross actions between adjustments, the plurality of adjusting mechanisms are allocated to the optical engines. As a result, the adjustments can be easily performed.
