Abstract

A base plate (2) fixed under the floor of a nacelle carried by a balloon and has a pivoting frame (7) suspended underneath. This frame supports a lower frame (70) which itself supports a platform (3) through crank arms (13). The assembly has cables attached to permit anchoring of the balloon to the ground. The platform carries the camera (4) on which an electronic sight (11) is mounted to permit transmission to the ground of the view to be taken by the camera. Servomotors (10,10') on the frame enable the platform to be displaced vertically by the crank arms. A servomotor (9) at the attachment to the base plate enables the platform to be rotated. These servomotors are controlled from a receiver (12) which obtains various commands from a transmitter on the ground.

Description

La présente invention a pour objet un dispositif de prises de vues aériennes. The present invention relates to a device for aerial photography.

De façon classique, les photographies aériennes sont prises par des opérateurs véhiculant à bord d'avions équipés spécialement. Conventionally, aerial photographs are taken by operators on board specially equipped aircraft.

Or, ce processus n1 est pas sans présenter de nombreux inconvénients, étant donné que d'une part, il entrasse des frais considérables et ce, à un moment où on cherche à réduire au maximum les dépenses d'énergie, et, que d'autre part, il ne donne pas des résultats entièrement satisfaisants, en raison de la vitesse et des vibrations de l'appareil. D'autre part, les vols à basse altitude sont parfois impossibles (lignes électriques, grands immeubles, interdictions). However, this process is not without many drawbacks, given that on the one hand, it is piling up considerable costs at a time when it is sought to reduce energy expenditure as much as possible, and that on the other hand, it does not give entirely satisfactory results, due to the speed and vibrations of the device. On the other hand, flights at low altitude are sometimes impossible (power lines, large buildings, prohibitions).

La présente invention a pour objet de remédier à ces inconvénients en proposant un dispositif de prises de vues aériennes qui soit à la fois d'un prix de revient modique et puisse travailler avec toute la précision nécessaire,- notamment pour les relevés géographiques, les implantations d'usine, etc...  The object of the present invention is to remedy these drawbacks by proposing a device for aerial photography which is both of low cost and can work with all the necessary precision, - in particular for geographical surveys, locations. factory, etc ...

A cet effet, le dispositif qui fait l'objet de l'invention se compose d'un ballon mongolfière notamment de modèle réduit ; sous la nacelle de ce ballon, est suspendu un plateau portant un appareil motorisé de prise de vues, ainsi que des moyens de commande à distance de l'appareil de prises de vues d'une part, et de la position du plateau par rapport au ballon et du ballon lui-m8me d'autre part. To this end, the device which is the subject of the invention consists of a balloon balloon in particular of a reduced model; under the nacelle of this balloon, hangs a tray carrying a motorized camera, as well as remote control means of the camera on the one hand, and of the position of the plate relative to the balloon and the balloon itself on the other hand.

Donc, cette mongol fière de petite dimension permet d'ascension du matériel qui effectuera la prise de vues aériennes de façon particulièrement économique. Par ailleurs, il est très simple de télécommander ou de radiocommander l'ensemble y compris la mongolfière. So this proud Mongolian of small dimension allows the ascent of the material which will carry out aerial photography in a particularly economical way. In addition, it is very simple to remote control or radio control the whole including the hot air balloon.

Ce dispositif est d'un intérêt tout particulier par rapport aux dispositifs de prise de vues proposés selon l'art antérieur, étant donné que, d'une part, il permet de réaliser une économie considérable, et que, d'autre part, la précision de la prise de vues est excellente, en raison de la faible vitesse de la mongolfière ; on peut meme obtenir une immobilité totale en amarrant le ballon au sol au moyen de cribles.  This device is of very particular interest compared to the shooting devices proposed according to the prior art, given that, on the one hand, it makes it possible to achieve considerable savings, and that, on the other hand, the shooting accuracy is excellent, due to the low speed of the balloon; you can even achieve complete immobility by mooring the ball to the ground using screens.

Donc, la présente invention permet d'obtenir une prise de vues aériennes de meilleure qualité que les moyens utilisés de manière classique, et ce, d'une manière incomparablement plus économique.  Therefore, the present invention makes it possible to obtain better quality aerial photography than the means used in a conventional manner, and this in an incomparably more economical manner.

Selon une autre caractéristi -de l'invention, l'orientation de la plate-forme recevant les appareils de prises de vues est possible dans le sens horizontal par l'intermédiaire d'un demi-cadre supérieur qui pivote sur une butée a' billes et dans le sens vertical par deux articulations du demi-cadre inférieur. According to another characteristic of the invention, the orientation of the platform receiving the cameras is possible in the horizontal direction by means of an upper half-frame which pivots on a ball bearing. and vertically by two joints of the lower half-frame.

Pour pouvoir avoir une mobilité satisfaisante de l'appareillage, il est, de préférence, prévu trois servomoteurs, dont un solidaire de la base d'ancrage commande l'orientation horizontale du demi-cadre supérieur par rapport au ballon, tandis que les deux autres fixés chacun sur l'un des montants verticaux du demi-cadre et jumelés entre-eux, commandent l'orientation verticale du demi-cadre inférieur et de la plate-forme. To be able to have satisfactory mobility of the apparatus, there are preferably provided three servomotors, one of which is integral with the anchoring base controls the horizontal orientation of the upper half-frame relative to the balloon, while the other two each fixed on one of the vertical uprights of the half-frame and paired with each other, control the vertical orientation of the lower half-frame and the platform.

Une autre caractéristique essentielle de l'invention consiste à mettre en place, sur le plateau, une caméra vidéo ou un viseur électronique qui retransmet au sol l'image de la prise de vues que l'on effectue. Another essential characteristic of the invention consists in installing, on the set, a video camera or an electronic viewfinder which retransmits on the ground the image of the shooting that is carried out.

De façon préférentielle, cette caméra vidéo -et/ou ce viseur électronique est fixé au-dessus de l'appareil de prise de vues et de manière coaxiale. Preferably, this video camera and / or this electronic viewfinder is fixed above the camera and coaxially.

Selon une autre caractéristique de l'invention, le plateau porte un récepteur-radio permettant la commande des différents organes. According to another characteristic of the invention, the tray carries a radio receiver allowing the control of the various organs.
