The invention relates to a method for photographing on board of a flying rotating body and system for carrying out said method. According to said invention, pictures (V0, V90, V180, V270) are taken at predetermined angular positions of said flying body by a device which is rigidly fixed to the front
The invention relates to a method for photographing on board of a flying rotating body and system for carrying out said method. According to said invention, pictures (V0, V90, V180, V270) are taken at predetermined angular positions of said flying body by a device which is rigidly fixed to the front thereof and are exposed to an image geometrical transformation required for the display thereof.

The invention claimed is: 1. A method for formation, on a display stationed at a fixed post, of successive images of a scene towards which a flying body is moving while rotating about its longitudinal axis, said flying body communicating with said fixed post by virtue of a communication link, a picture-taking apparatus being fixed rigidly to the front of said flying body, in such a way that said apparatus turns with said flying body about said longitudinal axis, said method: taking with said apparatus, during each revolution of the rotation of said flying body about said longitudinal axis, several pictures of said scene each corresponding to a predetermined angular position of said flying body about said longitudinal axis, so that contours of said several pictures are inclined in mutually differing manners and so that, in each picture, the image of said scene and said contour occupy a relative position which depends on said corresponding predetermined angular position of said flying body and which is different from that of the other pictures; determining, among said pictures, a reference picture in which said relative position between the image of the scene and the contour is considered to be a relative reference position; applying in each picture, other than the reference picture, a geometrical image transformation processing to the image of said scene so that the relative position of the transformed image of said scene with respect to the contour is similar to said relative reference position; and displaying said reference picture and said pictures having undergone said geometrical image transformation processing successively on said display, wherein: the rotation of the flying body is initiated at the moment of its launching. 2. A system comprising: at least one flying body, rotating about its longitudinal axis as it flies; a fixed post furnished with a display that displays images of a scene towards which said flying body is moving while rotating; and a link that provides for the communications between said flying body and said fixed post; a picture-taking apparatus, fixed rigidly to the front of said flying body in such a way that said apparatus turns with said flying body about said longitudinal axis, said apparatus being configured to take, during each revolution of the rotation of said flying body about said longitudinal axis, several pictures of said scene each corresponding to a predetermined angular position of said flying body about said longitudinal axis, so that contours of said several pictures are inclined in mutually differing manners and so that, in each picture, the image of said scene and said contour occupy a relative position which depends on said corresponding predetermined angular position of said flying body and which is different from that of the other pictures and to determine, among said pictures, a reference picture in which said relative position between the image of the scene and the contour is considered to be a relative reference position; a control unit that controls said picture-taking apparatus at each of several predetermined angular positions of said flying body about said longitudinal axis; and a processor that performs geometrical image transformation processing for presenting the pictures taken by said apparatus at different angular positions with a similar relative position of the image of said scene with respect to the contour of said pictures, wherein: the rotation of the flying body is initiated at the moment of its launching. 3. The system as claimed in claim 2, wherein said control unit that controls the picture-taking apparatus comprises a gyroscopic system mounted on board said flying body and sensitive to the rotation of the latter about its longitudinal axis. 4. The system as claimed in claim 2, wherein said processor is stationed at the fixed post. 5. The system as claimed in claim 4, wherein a link between said picture-taking apparatus and said processor is effected by said link between said flying body and said fixed post. 6. The system as claimed in claim 3, wherein the sequencing of the operation of said processor is controlled by said gyroscopic system by way of said link between said flying body and said fixed post. 7. The system as claimed in claim 2, further comprising an illumination unit, mounted on board said flying body for lighting said scene. 8. A method for formation, on a display stationed at a fixed post, of successive images of a scene towards which a flying body is moving while rotating about its longitudinal axis, said flying body communicating with said fixed post by virtue of a communication link, a picture-taking apparatus being fixed rigidly to the front of said flying body, in such a way that said apparatus turns with said flying body about said longitudinal axis, said method comprising: taking with said apparatus, during each revolution of the rotation of said flying body about said longitudinal axis, several pictures of said scene comprising: a reference picture in which the relative position between the image of the scene and the contour of said reference picture is considered to be a relative reference position and in which the instantaneous value of the angle of rotation of the flying body is considered to be equal to zero, and pictures in which the instantaneous values of said angle of rotation are respectively equal to 90°, 180°, and 270°; illuminating said scene at least during the taking of said pictures; applying in each picture, other than the reference picture, a geometrical image transformation processing to the image of said scene so that the relative position of the transformed image of said scene with respect to the corresponding contour is similar to said relative reference position; and displaying said reference picture and said pictures having undergone said geometrical image transformation processing successively on said display.
