Description

The invention relates to advertising, in particular, to the design of programmable electronic-mechanical projection devices for volume-dynamic visualization of mainly advertising messages in the form of texts and / or images. Such devices can be used in outdoor and indoor light advertising, preferably in places of mass service or mass presence of people, at exhibitions and fairs to attract buyers and visitors.

One of the types of advertising is television advertising, which is realized by moving film as a carrier of figurative and / or textual information in front of a light source that sequentially projects individual frames on a TV screen. Similarly (in the sense of personnel filing) form images on displays of personal computers.

However, the use of pre-recorded films or videos for advertising purposes, for example, at exhibitions and fairs has long been familiar to visitors and therefore attracts, as a rule, specialists to watch. This is enough to advertise industrial equipment or materials, but clearly not enough to massively attract customers to shops and catering establishments and to advertise at mass trade shows and fairs. Moreover, only on PC displays, using modern animation programs, it is possible to relatively quickly rebuild the information content of advertisements, and ordinary film and television programs have to be monotonously repeated throughout the entire exposure time of advertised goods (programmable matrix projection devices such as “running line” or type of multiscreen television advertising complexes, which are usually based on a massive and bulky frame, on the front side of which in one or more rows are mounted from several hundred to several thousand light sources connected to a power source through a complex switching control device, which, for example, is described in US 4967373.

Matrix projection devices are effective for express transmission of news and advertising information on the streets and squares of megacities. However, advertising calls to streams of random people are ineffective, and the price of messages is too high for targeted attention to the goods and services of mass demand, which are usually produced by disparate small businesses. Therefore, the need to create simple, cheap to manufacture and easy to use projection devices remains relevant.

A projection device is known having at least one light source carrier, a rotation drive kinematically connected by a shaft with said light source carrier, a plurality of light sources located on the outer surface of said carrier, a microprocessor-based light source control unit that is equipped with a position sensor the specified medium, synchronizer and software for recording texts and / or images to be displayed and processing the recorded data to generate instructions for switching the light sources on and off, while all light sources are made point, the carrier of point light sources is cantilevered on the shaft of the rotation drive and made in the form of a rod, which has the shape of a generatrix of a suitable body of rotation, a thickness commensurate with the transverse size of the point light source, and measured in the radial direction, a width sufficient for such a rod to disappear from the observer’s field of view during rotation, the optical axis of each point light source is oriented in the normal direction to the generatrix of the rotation body, which is given a selected shape of carrier rod these light sources formed of LEDs or public representing the ends of fiber optic light guides (RU 2181507, G09F 13/30, publ. 04/20/2002).

In this invention, the main demonstration effect of hanging an advertising image and / or text in space on an invisible consumer medium does not depend on the specific form of the device and is achieved in all cases, since the change of “frames” occurs at a speed exceeding the inertia of the human eye.

The thin carrier rods of point light sources remote from the geometrical axis of the drive shaft disappear from the field of view of the observers upon rotation, which provides the illusion of free floating in the air of the demonstrated volumetric advertising messages. By choosing the form of the body of rotation that is suitable for the needs of a particular advertiser, various advertising effects can be provided. For example, carrier rods of point light sources in the form of a circular arc or an ellipse arc respectively allow static or dynamic advertising messages to be displayed on an invisible surface of a sphere or ellipsoid.

The disadvantage of this device is the complexity of its execution, due to the large number of light sources that must always be maintained, otherwise gaps will appear in such a picture that reduce the integrity of the picture itself and, accordingly, its information content.

Known advertising installation, which is a projection device containing a carrier of light sources in the form of an annular drum, a rotation drive kinematically connected by a shaft with the specified carrier of light sources, three vertical panels located on the outer side surface of the drum, each of which is equipped with a plurality of light sources located in in the form of demonstration columns, a microprocessor-based control unit for light sources, which is equipped with a position sensor for the carrier drum light, synchronizer and software for recording texts and / or images to be demonstrated and processing the recorded data to generate commands to turn on / off the light sources (US 4689604).

This well-known decision was made as a prototype for the claimed invention.

During operation of such a device, advertising messages are moved relative to the drum in a direction that is opposite to the direction of its rotation. In this case, the complete message may consist of many frames. The length of each of the frames shown is less than the circumference of the drum and is limited by the initial column of light sources and, after some interval, the final column of light sources. The position sensor starts the microprocessor, which generates a sequence of synchronization signals, a single one for each of the moving IP speaker demonstration column. For each revolution, the microprocessor sets the control sequences of the panels of light sources with the synchronization of their glow in each demonstration column.

In the described device, the visualization of texts and / or images occurs directly on the background of a clearly visible drum, which significantly reduces the effectiveness of advertising. Indeed, visitors to exhibitions and fairs and buyers have long been accustomed to luminous inscriptions and images on arbitrary media. Therefore, in cases where the search for goods and services of mass demand is not targeted, they usually do not perceive the advertising information addressed to them.

The basis of the invention is the task of changing the composition and structure to create such a programmable projection device that would provide the visualization of advertising messages with an astonishing effect of static image relative to a flat screen moving in space, showing this image.

The technical result achieved in this case is to increase the effectiveness of advertising by creating the effect of the constancy of the position of the image in space on a screen moving in space and the deployment of individual fragments of the image.

The specified technical result is achieved by the fact that in an advertising device including a projection panel for displaying text or graphic information, a rotation drive kinematically connected to the specified projection panel, an angular position sensor of the projection panel connected to a microprocessor configured to record the text or image information to be displayed , processing the recorded data to generate video stream signals, synchronizing and issuing these signals to the projection screen panel, the projection panel is made flat, the drive is made to rotate the projection panel with the plane of its screen in a vertical plane, the microprocessor is made with the additional function of correcting the video stream depending on the angle of rotation of the projection panel to provide a static video image on the screen of the projection panel relative to the projection panel moving in the screen space panels.

These features are significant and interconnected with the formation of a stable set of essential features sufficient to obtain the desired technical result.

The present invention is illustrated by a specific example, which, however, is not the only possible, but clearly demonstrates the possibility of obtaining the desired technical result.

Figure 1 is a block diagram of an advertising device with a demonstration of the deployment of a video image during screen rotation;

figure 2 - algorithm of the microprocessor in the correction mode of the position of the video image relative to the angle of rotation of the screen.

According to the present invention, the advertising device (FIG. 1) includes a flat projection panel 1 for displaying text or image information, a rotation drive 2 from an electric motor 3, kinematically connected to said projection panel and configured to rotate the projection panel by the plane of its screen in a vertical plane , a sensor 4 of the angular position of the projection panel associated with the microprocessor. The microprocessor 5 is configured to record the text or image information to be displayed, process the recorded data to generate video stream signals, synchronize, output these signals to the projection panel screen, correct the video stream depending on the angle of rotation of the projection panel to provide a static video image on the screen of the projection panel relative to the moving in the screen space of the projection panel.

The algorithm of the microprocessor with the correction of the formation of the video image and its position on the screen is presented in figure 2.

The rotation drive 2 is usually made on the basis of at least one electric motor 3, which, if necessary, can be equipped with a gearbox and other means such as mechanical gears for rotating the panel 1 in a given direction and at a given speed. For example, the rotation of the panel 1 can be carried out in a circle in the range of 360 ° or reciprocating in the range of 180 °. The electric motor can be easily selected by specialists from among those available on the market, and the gearbox or mechanical gears can be designed and manufactured by well-known methods. Therefore, the listed nodes of the rotation drive 2 are not shown in detail and are not indicated in the drawings.

The device control unit can be made on the basis of a suitable microprocessor, a position sensor of the specified rotation shaft and synchronizer. These nodes are also not particularly shown in the drawings, because they are available on the market and can be easily selected by specialists. In particular, the basis of this unit can serve as a switching control device, which is similar to the aforementioned device according to US 967373.

It will be appreciated by those skilled in the art that the control unit is equipped with hardware and software sufficient to record advertising messages to be displayed in the form of texts and / or images and process the recorded data to generate commands for generating the video stream and directing it to panel 1. Moreover, the synchronization function can be implemented directly by the microprocessor using appropriate software. As can be seen from the algorithm in figure 2, the microprocessor has the ability to form images in the Overlay mode ("live" video, which shows the video picture in real time, based on the principle of the multiplexer, with which we get a real, "live" video, allows key inserts one image (image) to another, the overlay is used, for example, if it is necessary to combine machine-generated text on the image (image) of the video for advertising purposes) and create the texture of the image in OpenGL mode, we provide om the appropriate type of renderer. These design and software features of working on a video picture today are well known and are used in practice, including in the preparation of advertising video information.

The OpenGL library is a three-dimensional graphics programming interface. The unit of information is the top, more complex objects consist of them. The programmer creates vertices, indicates how to connect them (lines or polygons), sets the coordinates and parameters of the camera and lamps, and the OpenGL library takes on the task of creating an image on the screen. OpenGL is ideal for cases where you need to create a small three-dimensional scene and not think about the details of the implementation of three-dimensional graphics algorithms. Using OpenGL, it is easy to create three-dimensional surfaces, imposing textures on them, lighting with light sources, creating fog effects, transparency, color mixing, and you can also apply a stencil, move scene objects, lamps and cameras along predetermined paths, thereby making the animation.

As a renderer, you can use a three-dimensional graphics renderer - AIR 2.0 - an advanced three-dimensional graphics renderer with a unique architecture and extensive features designed to quickly create high-quality images. AIR 2.0 is a hybrid renderer combined primarily for scanline rendering - fast rendering of complex scenes, blurriness (blurriness) of an image caused by the movement of an object and the depth of field of a spatial image, correct reflection, soft shadows and global lighting. AIR supports a wide range of geometric primitives, including polygon meshes, trimmed NURBs, subdivision meshes, curves, and particles. All primitives are maintained in their natural form. AIR also provides true ("sub-pixel") offset and high dynamic range (HDR) input and output. The product offers fully flexible software control of halftone processing and procedural modeling, and is also compatible with the standard for the description of three-dimensional scenes RenderMan ^® .

The function of changing the angular position of the video image on the screen is a program-solvable problem that also relates to the category of well-known and widely used techniques in the processing of video images.

A feature of the claimed image is a new combination of well-known tools that allow you to organize a new effect of representing the image on the screen.

Thus, it is seen that the proposed advertising device, built using widely used software and hardware in the control system, has a clearly visible structural difference in the use of a demo panel rotating in the vertical plane with its screen, on which the video image, which is static in spatial position, constantly changes in volume its format filling. In this way, the plot of the advertising material with imitation of animation is ensured by changing the displayed volume.

The proposed device can be easily manufactured industrially and is available to mass advertisers. It provides a demonstration of arbitrary figurative and / or text advertising messages with a new effect of stationarity of a picture on a field moving in space. This surprise contributes to the manifestation of the well-known to psychologists effect of subconscious transfer of the perception of advertising messages to the perception of advertised (especially new) goods and services and therefore actively stimulates their purchase and consumption.
