The invention provides a projector calibration method for forming a spherical target image at a viewing point. The projector calibration method includes the following steps. A first preset image is projected by a first projector to a dome screen, and a first deformed image is obtained by capturing an image of the dome screen using a first camera. A spatial relationship between the first projector, the first camera, and the dome screen is calculated according to the first preset image and the first deformed image. A first prewarp image is generated according to a target image, a spatial relationship between the first projector and the dome screen, and a spatial relationship between the dome screen and the viewing point. Projection is performed by the first projector according to the first prewarp image. In addition, a projection system using the method is also provided.

A projector includes: a projection unit projecting a projection image onto a projection surface where an object is located, the object defining a projection area where the projection image should be projected; a distortion correction unit correcting a distortion of the projection image; and a projection control unit causing the projection unit to project a guide image showing a range within which a predetermined site of the projection image can move according to the correction of the distortion, the projection control unit thus prompting a user to adjust a positional relation between the object and the range.

An object feature visualization system is disclosed. The system may include a computing device that generates video-mapped images to project onto physical objects. The video-mapped images may include features to be projected onto the objects. The projection of a video-mapped image onto the physical object allows for the visualization of the feature on the object. In some examples, the computing device receives a feature selection for a particular object, and generates a video-mapped image with the selected feature to provide to a projector to project the video-mapped image onto the physical object. In some examples, a user is able to select one or more features for one or more objects of a room display via a user interface. The system then projects video-mapped images with the selected features onto the physical objects. The system may allow a user to save feature selections, and to purchase or request additional information about objects with selected features.

A system for simulation of a composite beam is disclosed. The system can comprise a memory storing executable instructions and one or more processors coupled to the memory to execute the executable instructions. The one or more processors can be configured to generate a representation of the original beam pattern transmitted via a propagation of the composite beam, to invoke a propagation model that represents a distortion for the propagation of the composite beam, and to determine a representation of a distorted beam pattern based on the propagation model and on the representation of the original beam pattern transmitted via the propagation.

The present invention provides an interactive display screen integrated with a video camera optimized to capture the user, the user's correct gaze, and information inputted on or through the interactive display screen. A presenter writes or draws information on the display screen while facing an audience. The display screen displays digital photos or other multimedia objects that a user can annotate or otherwise manipulate. Meanwhile, the device captures the displayed multimedia information and combines it with a video stream captured from the video camera. No extraneous video production equipment or technical expertise is required to operate while providing a compact and easily transportable system.

Display systems include a display structure having a display surface, and an optical projector that is positioned relative to the display structure and that is configured to project an image onto the display surface.

The projection module projects a first projection image based on a projection scope. The photographing module captures a part of the first projection image based on a photographing scope, so as to obtain a first photographic image.

The processing module analyzes the first photographic image, so as to obtain a plurality of first grid point coordinates. The processing module calculates a plurality of preset grid point coordinates corresponding to a plurality of preset positioning grid points in the whole projection scope one by one according to the first grid point coordinates. The processing module determines a projection result in the projection scope according to the preset grid point coordinates.

Correction performance is improved regarding a synthetic blur in which a plurality of blur characteristics is synthesized, for example, a focus blur that occurs in a superimposed projection image, or the like. An image processing device according to the present technology includes: a correction unit that obtains a plurality of blur-corrected images by performing blur correction processing on an input image regarding a focus blur that occurs in a projection image by an image projection device, by using a filter coefficient for blur correction corresponding to each of a plurality of blur characteristics, the filter each being obtained on the basis of the plurality of blur characteristics; and an image output unit that individually outputs the plurality of blur-corrected images obtained by the correction unit.

A display system which controls a display of display content, includes: a processor; and a memory having stored thereon instructions executable by the processor. The instructions includes: performing image correction involving a change in a display position of the display content based on image correction data stored in advance; detecting an attitude change amount of a moving body; calculating, after the image correction is performed, a vibration correction amount of the display position of the display content based on the attitude change amount of the moving body and an image correction error of the image correction caused by vibration correction processing of correcting a display deviation caused by an attitude variation of the moving body; and controlling the display position of the display content based on the vibration correction amount.

A projection system and method for depth-based projection of image-based content is provided. The projection system receives a sequence of image frames to be projected on a physical surface of a three-dimensional (3D) structure. The projection system controls a depth sensor to acquire depth data associated with the physical surface and feeds a first input including the acquired depth data and a first image frame of the received sequence of image frames to a neural network-based model. The projection system further receives a set of geometric correction values as a first output of the neural network-based model for the fed first input and modifies the first image frame based on the received set of geometric correction values. The projection system further controls the illumination circuitry to project the modified first image frame onto the physical surface.
