The visual positioning device (101) includes an infrared light source (101b), an infrared camera (101a), a signal transceiver module (101d) and a visible light camera (101c). The three-dimensional surveying and mapping system (100) further includes a plurality of position identification points (102), a plurality of active signal points (103) and an image processing server (104). The image processing server (104) is configured to cache infrared images and real scene images shot by the infrared camera (101a) and the visible light camera (101c) and positioning information thereabout and store a three-dimensional model obtained through reconstruction. The present invention has the advantages of simple structure, no need for a power supply, convenience in use and high precision, etc.

An endoscope apparatus includes a display section with a touch panel having a left image display region and a right image display region and a control section. The control section is configured to perform display control so as to change, upon receiving a drag operation instruction while the left image display region selected, a position of a cursor displayed in the left image display region and the right image display region by an amount of variation da, and change, upon receiving a drag operation instruction while the right image display region selected, the position of the cursor displayed in the left image display region and right image display region by an amount of variation db.

A display system for realizing concentric light field with monocular-to-binocular hybridization, and methods thereof. At least some embodiments include a display arranged to emit or transmit light rays based on image content from a content engine, and an optical subsystem arranged to configure the light rays into a concentric light field. The concentric light field provides a virtual image in a large, contiguous spatial region, such that each eye of the human viewer can detect monocular depth from the light field, to provide a large field of view.

An image processing apparatus is described comprising a first acquisition unit configured to acquire image data from an image capturing apparatus and a second acquisition unit configured to acquire display installation information indicating a configuration of one or more display screens in a display installation to be simulated. A generation unit is provided to generate, based on the display installation information and the acquired image data, a simulation image that simulates display of the image on the display installation. A display control unit is provided to display the simulation image on a display device.

[Problem] An aspect of the present disclosure provides a medical image processing system that facilitates the recognition of the position of a 3D model image in a medical image.

[Solution] A medical image processing system includes: an acquisition unit that acquires a real-time 3D surgical image of an operation site stereoscopically viewable by a surgeon and a 3D model image that is a stereoscopic CG image associated with the 3D surgical image; and a superimposition unit that performs enhancement such that the location of the 3D model image at predetermined spatial positions is enhanced with respect to the 3D surgical image or the 3D model image at the start of superimposition of the 3D model image at the predetermined spatial positions when the 3D surgical image is stereoscopically viewed on the basis of information set for the 3D model image.

A method of generating hologram data in a holographic display apparatus, including a hologram processing device generating hologram data and a display terminal reconstructing a hologram image in a three-dimensional (3D) space on the basis of the generated hologram data, includes generating depth map image data from input image data by using a deep learning engine for generating a depth map and calculating a complex value hologram on the basis of the depth map image data and the input image data to generate the hologram data.

Relay systems may be incorporated into optical systems to direct light from at least one image source to a viewing volume. Light from a plurality of image sources may be directed by relay systems to a viewing volume. Some light from the plurality of image sources may be occluded by an occlusion system to reduce undesirable artifacts in when the relayed light from the plurality of image sources are observed in the viewing volume.

A method includes receiving, at an intermediary layer, from a camera of a head mounted display (HMD), image data of a real-world operating environment of the HMD at a first time. The method further includes identifying, at the intermediary layer, one or more objects in the image data, determining, at the intermediary layer, coordinates of a region comprising the one or more identified objects, determining a display permission for the one or more identified objects, modifying the image data in the region comprising the one or more identified objects according to the display permission and outputting the modified image data to an application executing outside of the intermediary layer.
