  • the views provided by the immersive camera system (10) and the PTZ camera system (20) may be correlated through a variety of methods. Thus, the views from two or more cameras can be matched. For instance, where the views provided by the immersive camera system (10) and PTZ camera system (20) have been correlated, a user may choose an object or event of interest within the view provided by the immersive camera system (10), then command the PTZ camera system (20) to provide a view of the same object or event of interest.

  • Such geography-dependent correlation may be suitable where, for example, the distance between all or part of the image capture system (4) and an object in the environment is known and fixed and/or some geometric characteristic of the environment is constant (e.g., the floor or ground is always flat).
  • correlation may also be performed in a manner that is independent of the geography of the environment.
  • Such geography-independent correlation may be desired where the image capture system (4) will be mounted to a mobile platform or where the environment is dynamic (e.g., characteristics of the environment are subject to change, the ground or floor is not flat, the environment is otherwise unknown, etc.).
  • parallax may be encountered by having non-co- linear lines of sight among the plurality of cameras or camera systems. While the parallax effect, if not accounted for, may adversely affect the accuracy of correlation attempts, it will be appreciated that the impact of the parallax effect on correlation accuracy may be negligible or otherwise acceptable with respect to objects and events that are beyond a certain distance from the image capture system (4). For instance, where an image capture system (4) such as the one shown in Fig. 2 is mounted atop a 15-foot high post (66), the parallax effect may be negligible with respect to objects and events that are further than 40 feet away from the post (66). In certain applications it may be desirable to reduce or minimize parallax by moving the respective lines of sight closer together, while in other applications parallax may be acceptable or even desirable.
  • the view or image provided by the immersive camera system (10) is mapped, such as by Cartesian, cylindrical, or spherical coordinates by way of example only.

  • the processor (6) determines or receives the coordinates corresponding to the line of sight direction.
  • the PTZ camera system (20) may be correlated by using the same coordinates.
  • This may be accomplished by "assuming" that the immersive and PTZ camera systems (10, 20) have the same point of origin, and orienting the PTZ camera system (20) such that its line of sight passes through the selected coordinates relative to the point of origin "shared” by the immersive and PTZ camera systems (10, 20).
  • This approach may provide the user with a view from the PTZ camera system (20) that is "close enough” to the selected object of interest, such that the user may subsequently adjust the orientation of the PTZ camera system (20) as necessary or desired for a better view of the object of interest by any suitable means.

  • Each data point coordinate set may also include a coordinate or coordinates representing the distance of a data point object relative to the camera systems (10, 20).
  • each data point object position may be noted by manually orienting the PTZ camera (22) to view the data point object (e.g., such that the data point object is at the center of the PTZ image or aligned with crosshairs), then clicking with a mouse on the data point object as depicted in the navigable immersive or equirectangular image (102, 100) captured by the immersive camera system (10). Such clicking may cause the system to note the data point coordinates relative to each camera system (10, 20).
  • This noting may be accomplished by noting the point in the navigable immersive or equirectangular image (102, 100) on which the user clicked, while also noting the orientation of the PTZ camera (22) (e.g., the orientation of the line of sight of the PTZ camera (22)) at the time the user clicked.

Such clicking may replace or update the coordinates (relative to the PTZ camera system (20)) that were noted when the user clicked on the navigable immersive or equirectangular image (102, 100). This refining or updating may be desired when the user has difficulty in precisely centering the data point object within the PTZ image (104), by way of example only.

  • the data point coordinates with respect to the immersive camera system (10) will be noted and associated with the corresponding position or data point coordinates with respect to the PTZ camera (22), then the system will position the PTZ camera (22) to the next predetermined orientation. These steps may be repeated several times until the desired number of data point coordinate sets have been collected.
  • the number and positioning of the predetermined PTZ camera (22) orientations may be preprogrammed or set by the user. While the word "predetermined” is used to describe orientations of the PTZ camera (22) during zero point calibration, it is meant to include PTZ camera (22) orientations that are selected at random. It will also be appreciated that the data point coordinate sets for the PTZ camera system (20) may correspond with the predetermined orientations, such that data point coordinate sets need not be "collected.” In zero point calibration, data point objects may typically be arbitrary (e.g., whatever the PTZ camera (22) happens to be pointing at when positioned at one of the predetermined orientations). Where a crosshairs or other indicator is used for zero point calibration, such an indicator may be displayed only during this process. Suitable variations of zero point calibration will be apparent to those of ordinary skill in the art.

For each of these different orientations, the user may find the corresponding spot of light as shown in the navigable immersive or equirectangular image, and click on the depicted spot of light to note the coordinates.
  • the click causes the processor (6) to note the location of the click in the navigable immersive or equirectangular image as the location of the data point object relative to the immersive camera system (10), while simultaneously noting the orientation of the PTZ camera system (20) as the location of the data point object relative to the PTZ camera system (20).

  • this method of correlation may be suitable for situations where at least parts of the immersive and PTZ camera systems (10, 20) are not physically located in close proximity to each other. However, closer proximity of the immersive and PTZ camera systems (10, 20) may lead to less parallax, and reduce the number of data point coordinate sets to be collected.
  • a laser such as a laser range finder, or other correlation apparatus may be used to map the environment or create a three dimensional model of the environment, which may be represented by data stored in the storage device (30) for reference.

Abstract

L’invention concerne un système vidéo qui comprend un système de caméra submersible et un système de caméra panoramique/basculante et avec zoom. Il est possible de commander chaque système de caméra de façon à capturer une image vidéo d’au moins une partie d’un environnement. Un affichage vidéo peut afficher au moins des parties des images capturées par les systèmes de caméra.
