DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The present invention relates to a method and apparatus for taking views and enabling visual spheres to be recorded.
The wording "visual spheres", is defined as the whole luminous reality which can be seen from any point of the environment. Up to the present, it was not possible to take a complete surrounding photograph from any point of the environment. Devices for taking panoramic photographs, for example, were known, but none of these devices enables the whole luminous reality to be recovered.
SUMMARY OF THE INVENTION
One object of the invention is to solve the problem of producing as images, the whole luminous reality from any point of the environment by means of a method wherein a volume of revolution, for example a sphere, is devided into portions which may be substituted by plane surface areas or facings. These surface areas are then assembled to form a volume of revolution of substantially corresponding shape, for example a "pseudosphere".
Another object of the invention is to provide visual recording device enabling images to be recorded for any point of the environment, such images being able to recover the planes, faces or facings obtained from avoid volume of revolution while being able to possibly overlap each other.
Still another object of the present invention is to provide a device enabling the images corresponding to the facings which will be recorded and to be able to use the images thus recorded on to be projected on any space support of any volume of revolution located in any point of the environment, whatever may have been used for previously recording.
Thus, the present invention relates to a method for taking photographs and enabling the visual spheres to be recorded, wherein a surface area of revolution, for example, a sphere, is divided into portions which are able to be replaced by plane surface areas or facings. As many photographs as facings are taken for a first given point of the environment ("first shot point") by using suitable optical or video-optical means while determining the orientation of each photograph with respect to the latitude and the longitude. The images corresponding respectively to the facings are recorded and the images thus recorded are projected on any space support of any volume located around a second space point of the environment ("second shot point"). The first shot point may be spatially identical or different from the second shot point.
The invention also relates to a device for embodying the above-stated method. This device includes a U-shaped fixing support on which is mounted recording optical means. The support is affixed by means of two axes bearing on the legs of the U-shaped support is and pivotally mounted in bearings provided into the legs of a second U-shaped fixing support which is secured to a vertical axis pivotally mounted in a bearing within the upper face of a leg. A face opposite that provided for the bearing of the vertical axis includes a means for affixing the device to suitable support means, thus enabling optical recording means to be moved about two perpendicular axes defined by the respective extensions of the aforesaid axes to be able to rotate in any direction around the focal point defined by the intersection of the axes.
The optical means may any optical or video - optical devices able to record photographs and to restore them on supports so as to able to do further work. Motor-reduction means, which is usually a reducer transmitting the movements of a motor, for example an electrically driven motor, are also provided to respectively locate the fixing supports and the optical means. The motor may be controlled by electronic information means consisting, for example, of an electronic cooperating with a microprocessor card. These electronic information means are connected to an electric supply system, such as batteries.
