Description

 The invention relates to television technology, namely to color stereo television systems designed for television broadcasting and for use in industrial purposes.

 A known method of obtaining and reproducing a three-dimensional image, in which a stereo pair of a three-dimensional image is formed, determines the azimuthal coordinate and eye range of one observer, regardless of the process of projecting a stereo pair image, the previously obtained (computer-synthesized) image of a stereo pair is directed by the obtained spatial coordinates in the direction of the observer's eyes.

A device for implementing the above method comprises a synthesized image generator, a stereoscopic display with a lenticular screen, an observer coordinate determinant containing two infrared cameras operating in the infrared range and an infrared reflector mounted on the viewer's chin [1]
A disadvantage of the known technical solution is the limitation of its use only for the formation and reproduction of the generated stereo pair of the volumetric image, the inability to reproduce the image for various angles.

A known method of forming and reproducing a three-dimensional image, in which it is proposed to form and transmit for playback a basic image including a flat image of one angle and the corresponding parallax values for all decomposition elements of a given image, and when reproducing from a signal of a basic image, generate image signals of any angles [2]
The disadvantage of this method is the difficulty in its implementation, which consists in the need for the simultaneous formation of multiple image angles for all possible positions of the observer, resulting from this condition, high requirements for the bandwidth of the information channel, as well as to the performance of the computer when realizing the volumetric image of the synthesized computer.

 Closest to the proposed one is a method for generating and reproducing a volumetric image, including frame-by-frame generation of electrical signals of the image of the space of objects with the inclusion of electric brightness, color signals for each element of the decomposition of a frame, the inclusion of horizontal-frame signals, determining the range of each element of the decomposition of a frame, forming electrical signals of the basic image of the frame by including in the electrical signal of each of the elements is decomposed ia frame signal range, the transmission of the electrical signal of the basic image of the frame for playback and conversion when playing back a three-dimensional image of the electrical signals of the basic image of the frame in the optical image angles.

A device for implementing this method contains at least two transmitting chambers, a clock generator, a basic image shaper, including high-pass filters and an analog-to-digital converter, connected by its input to the output of one of the transmitting chambers, and by the output to the corresponding inputs of the output device of the machine word shaper whose output through the communication channel is connected to the input of the image reproducing device. The specified device provides the conversion of optical signals into electrical ones, filtering from noise, forming a basic image with parallax signals in a digital code by delaying the signal from each transmitting camera, comparing them and finding decomposition elements from different transmitting cameras that display the same piece of space of objects, with the simultaneous determination of the color and brightness of the decomposition element according to the information of one of the transmitting cameras and the subsequent formation of machine words in series m code with its transmission to a reproducing device, where signals of line-frame scanning, color, brightness and range of each element of frame decomposition are extracted from the received information [3]
The disadvantages of the prototype are the high requirements for the bandwidth of the information channel, as well as the performance of the computer when realizing a multi-angle three-dimensional image both synthesized on a computer and three-dimensional image of real objects due to the need to simultaneously form multiple image angles for all possible positions of the observer and the formation and playback of individual values of the range of each of the elements of the decomposition of the frame.

 The aim of the invention is to reduce the requirements for the bandwidth of the information channel, as well as to the performance of the computer when forming a three-dimensional image and when it is multi-view for individual views, depending on the position of one or more observers in space.

 The aim of the invention is also to reduce the requirements for the bandwidth of the information channel and the performance of the computer when forming a three-dimensional image and reproducing real objects in real time.

 The aim of the invention is also the preservation of the proportions of objects in the formation and reproduction of three-dimensional images of real objects.

 In addition, the aim of the invention is to determine the range of portions of the image space of objects for each element of the decomposition of the frame during the formation of the signal volumetric image of real objects in real time.

 One of the objectives of the invention is the implementation of the possibility of shifting the field of view of the transmitting cameras without changing the position of the building axes of their optical systems.

The essence of the invention lies in the fact that when implementing the method of forming and reproducing a three-dimensional image
frame-by-frame formation of electrical signals of the image of the space of objects with the inclusion of horizontal-scanning signals in them, as well as with the inclusion in them for each element of decomposition of a frame of electrical signals of brightness, color,
determining the range of portions of the imaged space of objects for each element of the decomposition of the frame,
the formation of electrical signals of the basic image of the frame by including in the electrical signal of each of the elements of the decomposition of the frame signal range,
transmission of the electrical signal of the base image of the frame for playback,
conversion when reproducing the volumetric image of the electrical signals of the base image of the frame into an optical image angles.

In contrast to the known technical solution, the depicted space of objects in range is divided into n-plans,
the range of portions of the depicted space of objects for each element of the decomposition of the base image is determined equal to the range of one of the plans,
before converting the electrical signals of the base image into an optical image of the angles, the coordinates of the eyes of the observers are determined and, according to certain coordinates in the direction of the eyes of the observers, an optical image of the angles is formed,
the optical image of the angles is formed by the electrical signals of the base image by alternately playing during the frame on the information panel with adjustable light transmission of the information pictures of the angles,
each of the information pictures of the image angles is formed for one of the eyes of the observers in accordance with its coordinates and with the playback of the decomposition elements in decreasing order of magnitude of the range of the portions of the image space of objects displayed by them with the number of decomposition elements common to all information pictures and common for the decomposition elements displaying one and the same piece of space of objects with characteristics of brightness and color,
simultaneously with the reproduction of informational pictures of the angle images, light beams are formed that pass through the information panel, covering the entire area of its working area, and directed into the eye of the observer for whom this informational picture is formed,
the number of reproduced information pictures of the image angles during the frame is equal to the number of eyes of the observers.

 This will reduce the requirements in the bandwidth of the information channel, as well as the performance of the computer when forming a three-dimensional image and reproducing it for individual angles depending on the position of one or more observers in space.

 The method of forming and reproducing a volumetric image can be implemented in such a way that the frame-by-frame formation of electrical signals of the image of the space of objects is carried out using two or more transmitting cameras.

In this case, the transmitting cameras are positioned so that
a) the construction axis of their optical systems are parallel to each other, and the transmitting cameras are equidistant relative to the imaged space of objects,
b) the construction axes of their optical systems intersect at one point, and the transmitting cameras are located equidistantly (at the same distance) relative to the intersection point of the construction axes of their optical systems.

 As in the case of parallel and intersecting building axes of the transmitting chambers, the separation of the displayed space of objects in range into n plans is carried out on planes passing through the intersection points of the clock (instantaneous, temporary) positions of the optical axes at the time the transmitting camera receives video information connecting the centers of the decomposition elements on the screens of transmitting cameras with the centers of the portions of the displayed space of objects displayed by these elements.

The method of forming and reproducing a three-dimensional image can be implemented in such a way that
the distance between the centers of the lenses of the adjacent transmitting cameras is determined by the ratio
S s • L / l,
where S is the distance between the centers of the lenses of the adjacent transmitting cameras; s is the distance between the centers of the eyes of the observers, L is the distance from the transmitting cameras to the point of intersection of the construction axes of their optical systems; l is the distance from base point 0 to the screen of the reproducing device.

 This is necessary to maintain the proportionality of the size of reproduced objects.

The method of forming and reproducing a three-dimensional image can be implemented in such a way that determining the range of portions of the image space of objects for each element of the decomposition of the frame is carried out by
separating from the electrical signals the elements of the decomposition of the frame coming from each of the transmitting cameras color signals for R, G and B colors separately,
taktovy comparison on amplitude on R, G and In colors separately n times of the duplicated selected signal of one color of one transmitting camera with n successive selected signals of the same color of the next transmitting camera,
delays received from the transmitting camera n successive signals for a time T1, determined from the ratio
T1 t _e • n,
where t _{e is the} time of viewing one decomposition element,
n the number of consecutive plans selected for the formation and reproduction of a three-dimensional image of the space of objects,
recording the measure number at the moment of coincidence of the color signals in amplitude,
generating a range signal by the tact number at the moment of coincidence of the color signals in amplitude, moreover, to generate the signal of the basic image, the electrical signals of the image elements are duplicated from one of the transmitting cameras with the selected color signals of R, G and B colors separately and the received synchronous signals are connected to them range.

 This is necessary for the formation and reproduction of a volumetric image of real objects in real time.

The method of forming and reproducing a three-dimensional image can be implemented in such a way that
n times duplicated signals are delayed by the time T2, determined from the ratio
0 <T2 ≅ T1.

 This is necessary to shift the field of view of the transmitting cameras without changing the position of the building axes of their optical systems.

 Range shaper 7 (Fig. 4) contains three decoders 20 (20-1, 20-2, 20-3), the inputs of which are inputs of range shaper 7, connected to three cameras 4 (respectively, 4-1, 4- 2, 4-3), nine high-pass filters 21 (21-1R, 21-1G, 21-1B, 21-2R, 21-2G, 21-2B, 21-3R, 21-3G, 21-3B), connected three for R, G and B colors to each of the decoders 20 (20-1, 20-2, 20-3) parallel to each other.

 Range Shaper 7 also contains twelve delay lines 22 (22-1R, 22-1G, 22-1B, 22-2Ra, 22-2Ga, 22-2Ba, 22-2Rc, 22-2Gc, 22-2Bc, 22-3R , 22-3G, 22-3B) connected to each of the high-pass filters 21, one for R, G and B colors for the chains of extreme cameras 4-1 and 4-3 and two for R, G and B colors, in parallel each other for the circuit of the intermediate camera 4-2.

The number of taps for the delay lines 22-3R, 22-3G, 22-3B in the circuit of the extreme camera 4-3 is equal to one. These delay lines delays the video signal for a time T2. Since the delay time T2 can vary, the delay lines 22-3R, 22-3G, 22-3B are configured to change the delay time of the signal with a step t _s .

 The number of taps for the delay lines 22-1R, 22-1G, 22-1B in the circuit of another extreme camera 4-1 is equal to the accepted number of plans of the imaged space of objects, namely four. The signal from each of the taps is shifted in time relative to the signal from the previous tap by one clock cycle, duration te (te is the time of viewing one image element).

In the intermediate connections camera 4-2 with two delay lines 22 for one color, 22-2Ra one delay line, 22-2Ga, 22-2Ba have one outlet and configured to change the delay time increments _of t, and the other, parallel to them included 22-2Rc, 22-2Gc, 22-2Bc, have the number of taps equal to the accepted number of plans of the depicted space of objects, namely four.

 Range Shaper 7 contains six differential comparators 23 (23R "1-2", 23G "1-2", 23B "1-2", 23R "2-3", 23G "2-3", 23B "2-3 "), one for two delay lines 22 of the same color from the circuits of adjacent cameras 4 connected by their inputs to the outputs of these delay lines 22.

 Each of the six differential comparators 23 consists of n comparison elements according to the number of received plans (in our case, n 4), in which the signals of the same color are compared from each tap of one of the delay lines 22 of the circuit of one camera 4 with the current delayed signal from the output of the corresponding line delays 22 of the circuit of another camera 4, and the signals of adjacent cameras 4 are compared, namely, the signals of camera 4-1 are compared with the signals of camera 4-2 and, accordingly, the signals of camera 4-2 with signals from the camera 4-3.

 The range signal generator 7 also contains two majority logic blocks 24 (24 "1-2" and 24 "2-3"), one majority logic block 24 for three differential comparators 23 in the chains of two adjacent cameras 4 and an OR 25 circuit.

 Each of the blocks of majority logic 24 consists of n elements of the majority logic “two out of three” for each of the plans (in our case 4). The signal at the output of each element of the majority logic block appears when a signal is supplied to two of the three inputs.

 The outputs of the differential comparators 23, processing the signals of two adjacent cameras 4, are connected to the inputs of one of the blocks of majority logic 24.

 The signal generator of the basic image 9 (Fig. 5) contains an analog-to-digital converter 26, connected with its input to the output of the decoder 20-2, and with outputs to the input register 27.

The signal generator of the basic image 9 also contains color registers 28 (28R, 28G, 28B) for R, G, and B colors, each of which is made of eight rulers of four cells of color 29, a machine word shaper 30, and a range register 31 consisting of two lines of four (according to the number of plans) cells of range 32 in each. The number P of rulers of the range register 31 is determined from the expression
n 2 ^P ,
where n is the number of plans of the depicted space of objects.

 In our case, when n 4 is the value of P 2. The base of the degree "2" corresponds to the binary range calculation system.

 The outputs of the lines of color registers 28 and range register 31 are connected to the corresponding inputs of the machine word generator 30.

 The information part of the machine word has the form shown in FIG. 6, and includes information on color, brightness, and range (plan number of each decomposition element). In addition, the machine word includes the service information usual for television information: address, clock pulses, etc.

 Range signal shaper 7, base image signal shaper 9, clock pulse generator 8 can be performed, for example, on 155 series microcircuits, in particular on 155TM2, 155IR13, 155IR22 microcircuits. As an analog-to-digital converter 26, conventional circuits used in color television, for example SDA 9087, can be used.

 The control unit 14 contains a coordinate-brightness unit 33 and an information block 34, the outputs of which are electrically connected respectively to the input of the matrix light source 12 and to the input of the information panel 11. The first and second inputs of the coordinate-brightness unit 33 are electrically connected respectively to the first output of the calculator 18 and the first output of the input device 10. The input of the information block 34 is electrically connected to the second output of the computer 18.

 The information block 34 in conjunction with the information panel 11 provide the formation of information pictures of image angles. As them can be used, for example, a projection panel with an Ovation 822 control unit from Proxima or Panel Book 450 from InFocus.

 Blocks similar to the brightness blocks of television receivers or monitors can be used as a coordinate brightness unit.

 The method of forming a three-dimensional image and the operation of the device for its implementation are as follows.

 When implementing the method, three television cameras 4 (4-1, 4-2 and 4-3) carry out frame-by-frame formation of electrical signals of the image of the space of objects 5 with the inclusion in them for each element of decomposition of the frame of electrical signals of horizontal scanning, brightness, color. The cameras 4 are arranged in such a way that the building axes Hb of their optical systems are parallel to each other with an equidistant arrangement relative to the imaged space of objects or intersect at one point F, while the cameras 4 are located equidistantly (at the same distance) with respect to point F.

 The case where the construction axes Hb of the optical systems are parallel to each other is equivalent to the case depicted in FIG. 1, if the intersection point of the building axes F is moved to infinity. As a result of this, in the following, the example considers a more general case of using the invention with the intersection of the building axes Hb of all cameras 4 at one point.

The distance between the centers of the lenses of adjacent cameras 4 (4-1, 4-2 and 4-2, 4-3) is determined by the ratio
S s • L / l,
where S is the distance between the centers of the lenses of the adjacent transmitting cameras, s is the distance between the centers of the eyes of the observers, L is the distance from the transmitting cameras to the intersection point of the building axes of their optical systems, l is the distance from the base point 0 to the screen of the reproducing device.

Each decomposition element on the screen of any of the cameras 4 displays a specific area of the displayed space of objects 5. If, for each of the cameras 4, the center of each decomposition element is connected by a straight line to the center of the displayed area of the space of objects 5, then we will get a diagram of the intersection of instantaneous positions (scan ) optical axes H of the cameras 4 (Fig. 2). In this case, the optical axis refers to the direction of view along which the camera 4 currently perceives the imaged space of objects. The optical axis of the camera 4-1 sequentially in time with each cycle occupies the position H $\genfrac{}{}{0ex}{}{\text{one}}{\text{one}}$ , H $\genfrac{}{}{0ex}{}{\text{one}}{\text{2}}$ , H $\genfrac{}{}{0ex}{}{\text{one}}{\text{3}}$ etc. The optical axis of the camera 4-2 sequentially in time with each cycle occupies the position H $\genfrac{}{}{0ex}{}{\text{2}}{\text{one}}$ , H $\genfrac{}{}{0ex}{}{\text{2}}{\text{2}}$ , H $\genfrac{}{}{0ex}{}{\text{2}}{\text{3}}$ etc. Each of the sections α, β, γ, ω of the imaged space of objects 5, located in the plane passing through the intersection points of the instantaneous positions of the optical axes H of the cameras 4, will be displayed by the decomposition elements of all cameras 4, in the field of view of which it falls. However, due to parallax, the decomposition element from the camera 4-1, relative to the decomposition element received from the camera 4-2 and reflecting the same area, will be shifted in time, determined by the range of the plan 6 (a, b, c, d, e, f, g or h) on which the displayed image space of objects 5 is located. Thus, the i-th decomposition element on the screen of the camera 4-1 and j will correspond to the same volumetric area a, β, γ, ω of the displayed space of objects 5 -th element of decomposition on the screen of the camera 4-2.

In FIG. Figure 3 shows the taktovaya time diagram of the operation of cameras 4-1 and 4-2, the signals from which are compared. The temporal positions of the optical axis of each of the cameras 4-1 and 4-2 are numbered in accordance with the number of the measure at which the optical axis occupies this position. The optical axis of the 4-1 camera on the 1st, 2nd and 3rd clocks sequentially occupies the position H $\genfrac{}{}{0ex}{}{\text{one}}{\text{one}}$ , H $\genfrac{}{}{0ex}{}{\text{one}}{\text{2}}$ , H $\genfrac{}{}{0ex}{}{\text{one}}{\text{3}}$ The optical axis of the 4-2 camera on the 1st, 2nd and 3rd clocks sequentially occupies the position H $\genfrac{}{}{0ex}{}{\text{2}}{\text{one}}$ , H $\genfrac{}{}{0ex}{}{\text{2}}{\text{2}}$ , H $\genfrac{}{}{0ex}{}{\text{2}}{\text{3}}$ .

 In FIG. Figure 3a shows the tact cycle time diagram of the operation of the circuit of the 4-1 camera on the first (1st cycle), second (2nd cycle), third (3rd cycle) and fourth (4th cycle) taps of the delay lines 22-1.

 In FIG. 3b shows a tact cycle time diagram of the operation of the circuit of the camera 4-2.

 In FIG. Figure 3c shows the tact cycle generation of the range signal when the signals from the cameras 4-1 and 4-2 coincide in the delay lines 22-1 and 22-2a (regardless of the color of the signal).

 The signals from the 4-1 camera in this example of use are delayed by a time T1 equal to four clock cycles. The signals from the 4-2 camera in this example are delayed by T2 T1 / 2, by two clock cycles.

 A one-on-one comparison of the signals of both cameras 4-1 and 4-2 shows that the signals of the decomposition elements representing the portion γ coincide on the first clock cycle and are assigned the range of the plan d, the first in the range of the plan with respect to point F.

 The signals of the decomposition elements representing the section w give a coincidence of the signals on the third step and they are assigned the range of the plan f, the third in range relative to point F.

 The signals of the decomposition elements representing sections b and α give a coincidence of signals on the fourth step and they are assigned the range of the plan g, the fourth in range relative to point F.

 Thus, the imaged space of objects 5 in terms of distance is divided into plans 6 along planes passing through the intersection points of the instantaneous positions of the optical axes connecting the centers of the decomposition elements on the screens of the cameras 4 with the centers of the sections of the imaged space of objects 5 displayed by these elements, while the range of the portions of the imaged space items for each element of the decomposition of the base image is determined equal to the range of one of the plans 6.

 Usually, when shooting in a theater, a circus, in a sports arena, the depicted space of objects in depth (the difference in the distances of the closest and most distant points) takes a certain number of consecutive plans 6. It follows from this that when designing a device for implementing the proposed method with In order to simplify the device, you can take some limited number of plans 6, for example, four, which will transmit the difference in the distance of the sections of the image space of objects 5.

By changing the delay time 12 with a step equal to t _s , one can change the composition of n consecutive plans 6, i.e. shift by the same value the number of assigned plans for all sections of the displayed space of objects 5 at the same time, and the delay time T2 is determined from the relation
0 <T2 ≅ T1.

 Subsequently, when reproducing a three-dimensional image, this circumstance will lead to the effect of a visible approximation or removal of the image space of objects 5. This visual effect can be used to change the field of view of cameras 4 without mechanical adjustment of the position of their construction axes.

 Thus, to obtain a good-quality three-dimensional image of the space of objects 5, it is enough to reproduce the areas located in planes passing through the intersection points of the instantaneous positions of the optical axes H of the cameras 4, having previously determined their range.

The determination of the range of areas of the depicted space of objects for each element of the decomposition of the frame is carried out by extracting from the electrical signals of the elements of the decomposition of the frame coming from each of the transmitting cameras color signals in R, G and B colors separately, beat-by-peak comparison in amplitude for R, G and B colors separately n times the duplicated selected signal of the same color of one transmitting camera 4 with n successive signals of the same color of the neighboring transmitting camera 4 by delay received from the transmitting minutes chamber 4 n consecutive signals at time T1, defined by the relation
T1 t _e • n,
where t _{e is the} time of viewing one decomposition element,
n the number of consecutive plans selected for the formation and reproduction of a three-dimensional image of the space of objects,
and delays n times of duplicated signals for a time T2, determined from the relation
0 <T2 ≅ T1.

 Then, the measure number is recorded at the moment of coincidence of the color signals in amplitude and a range signal is generated according to the measure number at the moment of coincidence of the color signals in amplitude.

 A device for forming a three-dimensional image works as follows.

 Video signals about the imaged space of objects 5, frame by frame, from television cameras 4-1, 4-2 and 4-3 in the form of sequentially issued electrical signals of the elements of decomposition of the frame with the inclusion in them for each element of decomposition of the electrical signals of brightness and color, as well as by including in them horizontal-scanning signals are supplied to decoders 20 (20-1, 20-2, 20-3).

 In the decoders 20, color signals are extracted from the full signal of each decomposition element, and the signals R magenta, G green and B - cyan are separated separately from each other.

 Then the signals are filtered out from interference in high-pass filters 21 (21-1R, 21-1G, 21-1B, 21-2R, 21-2G, 21-2B, 21-3R, 21-3G, 21-3B) and are delayed in delay lines 22 (22-1R, 22-1G, 22-1B, 22-2Ra, 22-2Ga, 22-2Ba, 22-2Rc, 22-2Gc, 22-2Bc, 22-3R, 22-3G, 22- 3B), with each color signal (R, G, B) being filtered and delayed by its chain.

Each package from the delay lines 22-1R, 22-1G and 22-1B relative to the previous one is issued with a delay received from the camera 4-1 of successive signals for a time T1, determined from the ratio
T1 t _e • n,
where t _{e is} the viewing time of one decomposition element, t _e 670 ns, and n is four and enters respectively in comparators 23R "1-2", 23G "1-2" and 23B "1-2".

 Each package from the delay lines 22-3R, 22-3G and 22-3B relative to the previous one is issued with a constant delay, for example, equal to T2 T1 / 2, i.e. equal to two clock cycles, and enters respectively the comparators 23R "2-3", 23G "2-3" and 23B "2-3".

 Each package from the delay lines 22-2Rc, 22-2Gc and 22-2Vc relative to the previous one is issued in a mode similar to the mode of issuing signals from the delay lines 22-1R, 22-1G and 22-1V and enters 23R "2-3, respectively ", 23G" 2-3 "and 23B" 2-3 ".

 Each package from the delay lines 22-2Ra, 22-2Ga and 22-2VA relative to the previous one is issued in a mode similar to the mode of issuing signals from the delay lines 22-3R, 22-3G and 22-3V, 22-2Ra, 22-2Ga, 22 -2Ba and enters, respectively, in the comparators 23R "1-2", 23G "1-2" and 23B "1-2".

 In the case of using a larger number of transmitting cameras located between the extreme ones (in our case, between the cameras 4-1 and 4-3), the signal from the delay lines installed in their circuits should be issued in the delay mode similar to the mode of the delay lines 22-2Ra, 22-2Ga, 22-2Ba and 22-2Rc, 22-2Gc, 22-2Bc.

 The color signals received from the delay lines 22 to the comparators 23 are compared in the differential comparators 23 in terms of the signal amplitude, and the comparisons are made for each color (R, G, B) separately. When the amplitudes of the compared signals coincide, the comparators 23 generate signals arriving at the blocks of majority logic 24. The block of majority logic 24 consists of n elements of the majority logic "two out of three" for each of the plans (in our case 4). The signal at the output of each element of the majority logic block 24 appears when a signal is applied to at least two of the three inputs. The coincidence at some measure of the amplitude of the signals from the chains of cameras 4-1 and 4-2 (or 4-2 and 4-3) of all three colors, or at least two of them, indicates that the color signals of the decomposition elements of the same section are compared imaged space objects. When at least two signals from differential comparators 23 appear at the input of the majority logic block 24, a signal is transmitted at one of the outputs of the majority logic block 24, which is transmitted to the OR circuit 25 and then to the range register 31. The output number of the majority logic block 24, on which the signal appeared, is uniquely associated with the measure number of the moment the signal appeared, and therefore with the range of the plan (d, e, f, g), which must be assigned to the signal of the decomposition element being processed.

 To generate the signal of the basic image, the electrical signals of the image elements from the camera 4-2 are duplicated with the selected color signals according to R, G and B colors separately and the received synchronous range signals are connected to them.

 From the output of the OR circuit 25, signals about the range (plan number) of the decomposition element (d, e, f, g) are sent to the signal shaper of the base image 9, where the color signals of this decomposition element are simultaneously sent to the analog-to-digital converter 26.

 In input register 27, the color signals acquire digital form, and then they are transferred to color registers 28 (28R, 28G, 28B), each of which is made of eight rulers of n cells of color 29 (n is determined by the number of plans, in our case n 4).

 In color registers 28, simultaneously entering the first cells of color 29, the chroma signals of the decomposition element pass from one cell of color 29 to another in each direction towards the output. During this movement of the signal on one of the clocks in the range register 31, consisting of two lines of four (according to the number of plans) range cells 32 in each, a range signal appears in one of the pairs of range cells 31. The range signals in range cells 31 also move toward each exit to enter the machine word shaper 30 with each clock stroke and, when entering the machine word shaper 30, form a signal of the base image decomposition element along with the incoming color signals.

 In the case when for four clock cycles, that is, during the passage of the color signal of the decomposition element from the input to the output of the color register 28, the range signal does not appear in the range register 31, due to the fact that when comparing the signals in the range former 7 from the chains of two pairs neighboring cameras 4 in amplitude there was no coincidence of their values in any of the pairs, this element of decomposition is assigned the range of one of the plans 6.

 The information part of the machine word has the form shown in FIG. 6, and includes information on color, brightness, and range (plan number of each decomposition element). In addition, the machine word includes the service information usual for television information: address, clock pulses, etc.

 After the formation of the signal of the decomposition element of the basic image, it is transmitted in the form of a machine word in a serial code through the communication channel 2 for reproduction. The functioning of the shaper range signal 7 and the shaper of the signal of the basic image 9 is synchronized by pulses from the clock generator 8.

 The method for reproducing a three-dimensional image and the operation of the device for its implementation are as follows.

 The optical system of the volumetric image reproducing unit includes an information panel 11, an optical shaper made, for example, in the form of a lens 13, and a matrix light source 12.

 In the optical system, in this case, a system of rectangular coordinates (X, Y, Z) is adopted (Fig. 7). The reference point is the center of symmetry U of the matrix light source 12, while W is the optical center of the lens 13 with coordinates Xw, Yw, Zw lo, where lo is the distance between the matrix light source 12 and lens 13, and D are the brightness points reproduced by the matrix light source 12 In FIG. 7 shows an optical image pickup circuit from a base point O (Xo, Yo, Zo) and an arbitrary observation point V (Xv, Yv, Zv) of some image point A (Xa, Ya, Za).

 Initially, in the absence of observers 17, the volumetric image reproducing unit 3 reproduces a flat image for one taken as the base position of the eye of the observer 17 (base point O (Xo, Yo, Zo). In this case, there are no signals from the counterreflectors at the input of the optical locator 15 16 and there are no signals, respectively, at the first input of the calculator 12. Information from the external storage device 19 to the third input of the calculator 18 or from the input device 10 to its second input is transmitted by the calculator 18 in playback tion without change.

 When observers 17 appear, and provided that they can change their location in front of the information panel 11, during the frame on the information panel 11 it is necessary to form 2M plane image angles from the flat image for the base point O, one for each eye M of the observers 17, and alternately apply them using 12 light beams synchronously formed on the matrix light source into the eyes of the observers 17, for which it is necessary to determine the spatial coordinates of the eyes of the observers 17.

 When the optical locator 15 is operating, the infrared beam formed in it, one element after another, illuminates part of the space in front of you (this part of the space will be called the angle of the viewing sector), sequentially reaching the counterreflectors 16 located, for example, on the forehead at the eye of the observer 17. Due to the large the reflectivity of counterreflectors 16 (3-4 orders of magnitude higher than the reflectivity of ordinary objects in the room), the optical locator 15 will capture powerful signals when the beam hits them. Since two counterreflectors 16 are fixed on the body of each of the observers 17 and they are located at a known distance from each other, the optical locator 15 will fix for each observer 17 sequentially two signals of approximately the same intensity spaced in time. Information about the current angular coordinates of the probe beam at the moments of fixation of signals from the counterreflectors 16 is supplied to the computer 18, which determines the spatial coordinates of the eyes of the observers 17.

By received coordinates synchronously
on the information panel 11 with adjustable light transmission during the frame, 2M information pictures of the angle images, each of which is formed for one of the eyes of the observers 17 in accordance with its coordinates, are alternately reproduced by electrical signals of the basic image;
on the matrix light source 12, during the frame, 2M luminous brightness points D are successively formed one by one for each eye, the light from which is formed by a lens 13 into a light beam passing through the entire working area of the information panel 11 and directed into that eye of the observer 17, in spatial coordinates which determines the location of the formed brightness point D on the plane of the matrix light source 12. If the optical shaper 12 is made in the form of a lens raster, then the light beam directed to that the observer’s hole 17, for which an information picture is reproduced on the information panel 11, should be formed using a set of brightness points D on the screen of the matrix light source 12, one for each raster lens. If the optical shaper 13 is made in the form of a slit liquid crystal matrix, then a light beam directed to the eye of the observer 17 will be formed using a light column on the screen of the matrix light source 12.

 Informational pictures of the angle images are formed with the decomposition elements being reproduced in descending order of the range values of the parts of the image space of objects displayed by them with the total number of decomposition elements for all informational images of the angle images and the brightness and color characteristics common to the decomposition elements identical for one frame. This is necessary so that when reproducing optical images of the angles, the decomposition elements representing the farther portions of the image space of the objects are replaced by the decomposition elements showing the closer portions that close the above farther sections in the space for this angle.

When forming informational pictures of image angles
the address part of the machine word is highlighted,
the address part of the machine word is recounted as many times as the eyes of the observers 17 are detected by the optical locator 15,
the information part of the machine word corresponding to this decomposition element is stored for all video pages,
each decomposition element of the base image is converted into 2M angular image decomposition elements, after which all of them are assigned the brightness and color of the corresponding decomposition element of the basic image,
the computer 18 generates one video page per view and transmits the contents of each video page for playback, and also generates signals that control the spatial separation of the perceived video information.

 The pulses from the clock 8, synchronize the operation of the entire device for the formation and playback of three-dimensional images.

 For an arbitrary observation point V (Xv, Yv, Zv), the coordinates of a certain point of the image A (Xa, Ya, Za) can be recalculated as follows.

 The coordinates of the projection Io of point A from the base point O onto the plane of the information panel 11 are Xio, Yio, Zio li, where li is the distance between the planes of the matrix light source 12 and the information panel 11. The coordinates of the projection lv of the same point A for the view from point V on the information panels 11 will comprise Xiv, Yiv, Ziv li. The coordinates of the brightness point Dv on the matrix light source 12, perceived from point V, will be Xdv, Ydv, Zdv 0.

The equations for recalculating the coordinates of the decomposition elements of the basic image on the plane of the information panel 11 and the brightness points on the plane of the matrix light source 12 in the case of the eye of the observer 17 at an arbitrary point V will have the form
a) to recalculate the coordinates of the decomposition elements of the basic image in the case of transmission and reception of the basic image of real objects, when there is information about the position of the decomposition element of the basic image on the plane of the information panel 11 and the plan number (coordinate Za) of the reproduced point A of the volumetric image
Xiv Xio • Zv • (Zo-Za) / (Zo • (Zv-Za)) - Xv • Za / (Zv-Za), (1)
Yiv Yio • Zv • (Zo-Za) / (Zo • (Zv-Za)) - Yv • Za / (Zv-Za), (2)
b) to recalculate the coordinates of the decomposition elements of the basic image in the case of transmission and reception of the basic image synthesized on a computer, when it with the coordinates of each image element A (Xa, Ya, Za) is already stored in the memory of the computer that recalculates the position of the image elements
Xiv Xa • (Za-li) / (Zv-Za) -Xv • (Za-li) / (Zv-Za), (3)
Yiv Ya • (Za-li) / (Zv-Za) -Yv • (Za-li) / (Zv-Za), (4)
c) to recalculate the coordinates of the brightness points, on the matrix light source 12, providing the perception of the video image from point V
Xdv (Zv • Xo-Xv • lo) / (Zv-lo), (5)
Ydv (Zv • Yo-Yv • lo) / (Zv-lo), (6)
d) to recalculate the coordinates of the brightness points on the matrix light source 12, providing the perception of the video image from point V provided that the coordinates of only one calculated point are used on the face of the observer 17, for example, on his nose, and the condition of using a fixed distance between the eyes of the observer 17, for example, equal to 64 mm, equation 7 takes the form
Xdv1 (Zv • Xo- (Xv-32) • lo) / (Zv-lo), (5a)
Xdv2 (Zv • Xo- (Xv-32) • lo) / (Zv-lo), (6b)
here the coordinate Xv is the coordinate of the nose bridge of the observer.

 The formation of video pages of image angles, sequential switching of pages in the order of their numbering and the element-by-element delivery of video information to a reproducing device is carried out by software. For example, if the coordinates are recalculated using a high-level language, for example, SI, then this organization of video pages can be called with the putpixel (X, Y, Color) procedure, or in Assembler with the mov [X, Y] Color command.

 Each observer 17 will receive a full three-dimensional image by the sum of two individual angle images corresponding to the individual coordinates of his eyes. In this case, the allowable time for switching on the elements of the information panel 11 may be of the order of 2 ms.

 The proposed method for generating and reproducing a three-dimensional image and a device for its implementation provide a multi-angle video image for several observers, and the stereo image angle is determined by the location of the observer relative to their common screen without any additional optical devices, including special glasses.

 It should be borne in mind that the embodiment of the invention described above and shown in the drawings is only a possible preferred embodiment. Various variations of the invention may be used with respect to the shape, size and arrangement of the individual elements, individual elements may be replaced by equivalent ones.
