A camera holding assembly that is configured to hold a plurality of cameras in a predetermined orientation includes a support having a plurality of receptacles. Each of the receptacles include at least one feature enabling a camera to be releasably retained therein as well as at least one and preferably at least three attachment features configured for enabling the camera holding assembly to be secured to another object. The receptacles are oriented about the support so that each camera, when loaded into the defined receptacles, is aimed in a different angular orientation. Images obtained from each retained camera can be stitched to create either a composite 360 degree×180 degree full spherical image or a composite 360 degree composite image of a scene of interest.

A method for collecting, organizing, presenting, and using data relative to the scene of an emergency situation is disclosed. The method uses a Responder Assets Management System (RAMS) composed of four modules including information, logistics, operations, and planning. The information module makes general information immediately available to responders. The logistics module assists in managing equipment resources during a contingency and includes an equipment manager interface for managing equipment used to respond to an emergency situation. The operations module supports daily operations responsibilities and scales to handle significant emergencies and includes at least one of a situational awareness interface, a response options generator (ROG) interface, an operations manager interface, a messenger interface and a status board interface. The situational awareness interface is designed for emergency and crisis response managers to provide enhanced, community-wide situational awareness using full immersion, spherical images, Geographic Information System (GIS) maps, site and floor plans, and a database interface to provide virtual walk-through, pre-incident plans, for contingency planning, training visualization, and operational support. The ROG interface provides automated response and resource estimates to decision-makers in command posts and on-site in developing a response to significant, unplanned events. The operations manager interface is used by a remote headquarters to monitor an on-going operation. The messenger interface is a pre-formatted, topic oriented messaging system that supports both informational messages and messages that automatically update system data and displays. The status board interface is a situation display of key situational awareness data. The planning module assists users in planning for critical events.

A method that enables creation of a 3D virtual reality environment from a series of 2D images of a scene. Embodiments map 2D images onto a sphere to create a composite spherical image, divide the composite image into regions, and add depth information to the regions. Depth information may be generated by mapping regions onto flat or curved surfaces, and positioning these surfaces in 3D space. Some embodiments enable inserting, removing, or extending objects in the scene, adding or modifying depth information as needed. The final composite image and depth information are projected back onto one or more spheres, and then projected onto left and right eye image planes to form a 3D stereoscopic image for a viewer of the virtual reality environment. Embodiments enable 3D images to be generated dynamically for the viewer in response to changes in the viewer's position and orientation in the virtual reality environment.

A system, method, and computer-readable instructions for virtual real-time computer simulation of visual images of perspective scenes. A plurality of 2D spherical images are saved as a data set including 3D positional information of the 2D spherical images corresponding to a series of locations in a 3D terrain, wherein each 2D spherical image comprises a defined volume and has an adjacency relation with adjacent 2D spherical images in 3D Euclidean space. As the input for a current virtual position changes based on simulated movement of the observer in the 3D terrain, a processor updates the current 2D spherical image to an adjacent 2D spherical image as the current virtual position crosses into the adjacent 2D spherical image.

The invention relates to a three-dimensional panoramic image generation method. The method comprises the following steps of: shooting a plurality of local images of a panorama at a low angle and a high angle at a horizontal position opposite to a tripod head by using a wide-angle camera respectively; synthesizing a plane composite image from each shot local image; converting the plane composite image into a three-dimensional spherical image; and performing three-dimensional navigation on the three-dimensional spherical image. By the method, the overlap region of the local images can be increased, so that the image effect is smoother and the obtained three-dimensional panoramic image is more similar to a real scene when the local images are synthesized into the plane composite image. The invention also provides a three-dimensional panoramic image generation system.

The invention discloses a method for generating an interactive dynamic panoramic image, which comprises the steps of converting each frame of image in a captured video to a latitude and longitude image through latitude and longitude mapping coordinates, further suturing into the panoramic image through optical reduction, then carrying out video coding, generating a panoramic video according to the time, converting each frame of the image in the panoramic video to a spherical image of a world coordinate system, carrying out view conversion and projection transformation, then carrying out synchronous playing with the time, and generating the interactive dynamic panoramic image.

A multiscale telescopic imaging system is disclosed. The system includes an objective lens, having a wide field of view, which forms an intermediate image of a scene at a substantially spherical image surface. A plurality of microcameras in a microcamera array relay image portions of the intermediate image onto their respective focal-plane arrays, while simultaneously correcting at least one localized aberration in their respective image portions. The microcameras in the microcamera array are arranged such that the fields of view of adjacent microcameras overlap enabling field points of the intermediate image to be relayed by multiple microcameras. The microcamera array and objective lens are arranged such that light from the scene can reach the objective lens while mitigating deleterious effects such as obscuration and vignetting.

A mask region extraction unit extracts a region that is to be masked in a panoramic image. A mask processing unit generates the object image where the region to be masked in the panoramic image is masked. A positioning unit adjusts the direction of a spherical image to the shooting direction of the object image. A mapping processing unit maps the mask-processed object image and the spherical image onto a three-dimensional (3D) object space as textures. A 3D image generator generates a 3D panoramic image, when the 3D panoramic image is viewed in a specified line of sight in such a manner so as to regard the shooting location of the panoramic as a viewpoint position.

A plurality of sphere models are subjected to normalization, and spherical surfaces of the plurality of sphere models are fused to form a single-frame panoramic sphere model of a multi-camera imaging system; the front and back panoramic spherical surface images are subjected to feature point matching; pose relation between the two panoramic spheres is calculated through a quaternion method, and then, the spherical surface images are subjected to conversion according to the obtained pose relation; and finally, information on the panoramic spherical surfaces is reduced to a plane image, and thus the image stabilizing effect is achieved. The method can effectively solve the problem that the overall pose transformation cannot be accurately positioned due to different pose change of each camera in a panoramic camera system.
