Definitions
- the subject of the invention is a device for printing over a large area.
- the field of the invention is that of building and interior or exterior decoration.
- An object of the invention is to transfer an image of large dimensions to a surface which is also large.
- Another object of the invention is to limit the means to be implemented to carry out this transfer. Another object of the invention is to allow this transfer to be carried out by an operator alone.
- Another object of the invention is to allow retouching / repairing a large image transferred onto a large surface too.
- various solutions are known for transferring an image to a wall.
- a first solution is to call on an artist who, from a model, will paint the wall. This solution is all the longer and more expensive as the image to be painted is complex. Indeed, if the image contains a lot of details, the painter must use brushes of sizes compatible with these details. It then takes an extremely long time to cover a wall of paint with a fine paintbrush.
- a second solution is to industrially print the image on paper which is then cut into strips. We thus obtain a wallpaper which must then be pasted on the wall.
- This solution poses the usual problems associated with the installation of wallpaper, namely the problems of connections between the different widths. Another problem comes from the differences in dimensions between the walls. This means that you never know the length of the webs or how to print and cut them.
- this solution the appearance of the material on which the paper is glued is lost, which alters the perception of the image and does not give the expected visual rendering.
- a third solution of the state of the art consists in using a giant plotting table which is positioned opposite the wall on which one wishes to transfer the image. This device is very bulky and heavy. Its size is such that it is sometimes impossible to bring it into a room and therefore to install it there. In addition it is impossible to implement it alone.
- this device has, for example, the external appearance of a paint roller whose roller has been replaced by the printing device.
- the printing device has two wheels for moving the printing device over the surface while ensuring a constant distance between the printing device and this surface.
- the device also includes a location and orientation device allowing it to precisely determine its position on the surface onto which an image is to be transferred. Knowing this position allows the device to read a file representing an image to be transferred to the wall, the position on the wall being associated with a position in the image file. This file is used to determine the print commands to be sent to the print heads of the device according to its position.
- This file includes an image whose dimensions are correlated with those of the wall.
- the position is determined, for example, by projecting a grid / grid on the wall. This grid is intercepted by an optical sensor of the device. Position crossing information is associated with each crossing of the grid. Reading this information allows the device to locate itself. Orientation is obtained either by the use of a second sensor giving a second position, or by the use of a gyroscope, or by reading the inclination of the grid, or by means of a motion sensor of the optical mouse type which allows to measure the movements of the device on the wall. An operator thus transfers an image to a wall by traversing this wall with the device according to the invention.
- the device also includes a memory making it possible to determine the parts of the wall which have already been painted. This prevents the accumulation of dye in certain places. This also exempts the operator from having to worry about the regularity of the passages of the device on the surface.
- the subject of the invention is therefore a device for printing an image on a large surface comprising:
- At least one gripping means allowing an operator to manipulate the device to reproduce the image on the large surface, characterized in that it comprises:
- Figure 1 An overview of a device according to the invention in an image transfer situation.
- Figure 2 An illustration of a location grid.
- Figure 3a and 3b illustrations of the device according to the invention and of the components it comprises.
- Figure 4a, 4b, and 4c illustrations of optical location sensor.
- Figures 5a and 5b illustration of a sound location.
- Figure 6 an illustration of steps implemented by the device according to the invention for the transfer of an image over a large area.
- Figure 1 shows a device 101 according to the invention positioned against a wall 102 to which an image must be transferred.
- the device 101 can be held and moved at arm's length, such as for example a paint roller.
- Figure 1 does not show the operator who handles the device 101 so as not to clutter the figure.
- FIG. 1 also shows a projector 103 positioned opposite the wall 102.
- the projector 103 then forms part of a variant of the invention allowing the device 101 to be located on the wall 102.
- the projector 103 projects onto the wall a grid or grid making it possible to provide the wall 102 with a system of coordinates which can be read by the device 101.
- FIG. 2 illustrates a grid such as that projected by the projector 103.
- This grid is a grid comprising horizontal lines and vertical, for example. The orientation of the lines is not necessarily horizontal or vertical, these lines can be oblique and define a mesh just as well.
- Figure 2 also shows that each intersection of two lines is associated with coordinate information. This information is, for example, a bar code, or an abscissa / ordered pair. This information is read by the device 101 which provides it with a location on the wall 102. Typically the lines of the grid are very fine, less than 0.2 mm, and are spaced on the wall from 5 to a few tens of mm. Coordinate information for an intersection is always placed in the same location relative to the intersection. This allows you to associate an intersection and coordinate information.
- Figure 3a shows a top view of a device 101 according to the invention.
- the device of Figure 3 is that implemented in Figure 1, other variants for the device 101 will be considered later.
- the device 101 has the same silhouette as a paint roller.
- the device 101 comprises a handle 301 making it possible to grasp and manipulate the device 101.
- the device 101 also comprises a body 302 fixed to the handle 301 and extending in a direction perpendicular to the handle 301. It is considered that the top of the device 101 is the part visible to an operator when the device 101 is placed against the wall 102 in working order.
- the underside is the part of the device 101 then facing the wall 102.
- the body 302 On its upper face, the body 302 comprises an optical sensor 303 making it possible to read the information projected by the projector 103.
- FIG. 3a also shows that the body 302 comprises a microprocessor 304, a sensor 305 for orientation, a memory 306 of image, means 307 for printing, means 308 for communication with an external device, and a program memory 309.
- the elements 303 to 309 are connected via a bus 310. When an action is given to the device 101, this action is carried out by the microprocessor 304 controlled by instruction codes from the memory 309.
- the memory 309 comprises several zones, each of these zones corresponding to instruction codes allowing the implementation of a function by the device 101.
- the memory 309 comprises a zone 309a corresponding to the determination of the location of the device 101.
- a zone 309b includes instruction codes for extracting data from the image recorded in the memory 306.
- a zone 309c includes instruction codes for controlling the printing means 307.
- Figure 3b shows the device 101 seen from below.
- the device 101 comprises a wheel.
- the wheels 311 and 312 are fixed on axes extending in a direction parallel to the plane of the wall 102 and perpendicular to the handle 301.
- the wheels 311 and 312 each include a pressure sensor which is connected to the bus 310. These pressure sensors act as switches for the operation of the printing means 307.
- the printing means are, for example, an inkjet device.
- This device then comprises 4 nozzle lines, 3 chromatic lines and a black line. These four lines are parallel and close to each other. At least one nozzle on each line is required to print a dot in any visible color. Together, these four lines form an inkjet print head.
- This print head can be seen as a succession of dots. Nozzles should only spray ink if they are well away from the surface to be colored. This distance is appreciated, for example, via the wheels 311 and 312. When the latter are in contact with a surface, this surface exerts pressure on the wheels, and this pressure is detected by the device 101 which then knows that it can activate the nozzles. In a variant, this activation is carried out by the operator who actuates a button of a man-machine interface 313 connected to the bus 310.
- This positioning of the printing means 307 makes it possible to limit the non-printable margins.
- the distribution of the nozzles over four lines is just one example. In practice, this distribution depends on the print head used. In particular, the distribution of colors varies from one manufacturer to another. These can be polychrome printheads on which the distribution of colors, ie nozzles, is particular, or monochrome printheads distributed in lines or in squares.
- the sensor 303 is therefore capable of acquiring a location image comprising an element of the grid and location information associated with an intersection of this grid element. Thanks to this location image, the device 101 is able to locate itself on the surface 102. In a variant, the sensor 303 does not systematically have an intersection in its field of acquisition. In this variant, between two measurements made on intersections, the sensor measures the relative displacement of the bottom of the grid using the elements of this grid that it perceives. To this end, it is possible to add imperfections to the grid making it possible to measure the relative displacement of said grid. This relative displacement of the grid relative to the sensor 303, therefore to the device 101, can also be evaluated by a sensor looking at the wall 102 and its imperfections.
- FIG. 6 illustrates a succession of steps implementing the device 101 according to the invention.
- FIG. 6 shows a preliminary step 601 of loading an image and displaying the grid.
- the display of the grid is achieved by the correct positioning of the projector 103 relative to the wall 102. This positioning is ensured, if necessary, using micrometric screws. The positioning is correct when the projected grid covers the surface to be painted.
- the image is loaded into the memory 306 using the connector 308.
- the image represents the fresco to be transferred to the wall 102.
- the dimensions of the image to be transferred are correlated with the dimensions of the wall 102 and the resolution of the impression.
- Print resolution is expressed, for example, in dots per inch (DPI, Digits Per Inch, or dots per inch). Resolution is a parameter of the 307 printheads.
- the dimension of the image recorded in the memory 306 in pixels is therefore obtained by multiplying the dimensions of the wall by the resolution of the print.
- Either memory 306 can contain all of the image, or the device 101 is permanently connected to a third-party device storing the image, the device 101 accessing this third-party device at will via the connector 308.
- a third-party device is, for example, an external hard disk or a laptop.
- From step 601 we pass to a step 602 for determining the position of the device 101. This position is determined by the interpretation by the device 101 of the image acquired by the sensor 303. Once the image to be transferred loaded , an operator can place the device 101 against the wall 102 and begin the transfer of the image, or printing of the image.
- From step 602 we pass to a step 603 of determining the orientation of the device 101. This orientation is obtained by the interpretation of the signals produced by the means 305.
- the device 101 To determine the print commands as efficiently as possible, the device 101 must also know the points which have already been printed. . Thus, each time the device 101 prints a dot, it updates the content of the memory 315. This update corresponds to a transfer of the image to be printed to the memory 315, as this image is printed on wall 102.
- step 604 once the device 101 has read the content of the memory 306 corresponding to its position, it reads the content of the memory 315 corresponding to its position, then it compares the result of the two readings.
- the result of a reading for a device having a linear print head, is the description of a line of dots, i.e. the description of a color for each point. If a point is marked as already printed in memory 315, it must no longer be printed again. The description of this point then becomes transparent.
- the device 101 therefore performs a subtraction between the result of the first reading and the result of the second reading.
- the result of the subtraction is a line description in which the points already printed are assigned a transparent color.
- the result of this subtraction is the print command.
- Step 604 corresponds to an extraction of information from the memory 306. From step 604 we pass to a printing step 605 in which the device 101 uses the printing command determined in step 609 to control the printing means 307. Each point corresponds to a certain number of nozzles. These nozzles are activated according to the color to be produced. For a transparent point, no ink is projected. In step 605, the device 101 also updates the content of the memory 315.
- Steps 602 to 605 are repeated cyclically, either at a fixed frequency, or each time the device 101 detects a movement. This detection is carried out either by the movement of the wheels, or via a sensor 316 connected to the bus 310 and located on the underside of the device 101, facing the wall 102, or directly by the sensor 303.
- the sensor 316 is then of the type of the one that equips optical mice and is able to provide direction and distance of movement.
- steps 602 to 605 makes it possible to transfer the image from memory 306 to the wall 102, by printing taking place during the movement of the device 101 over the entire surface of the wall 102.
- the projector 103 is replaced by a panel on which is printed a grid as described in FIG. 2.
- FIG. 4c shows such a panel 404 positioned parallel to the wall 102.
- the panel is then seen by sensor 303.
- sensor 303 is focused on the panel.
- the panel 404 is placed at a distance from the wall 102 such that there is room for an operator to manipulate the device 101 between the panel and the wall. The location and orientation of the device 101 are then made relative to the panel.
- localization is obtained by printing marks invisible to the naked eye.
- the device then includes a scanner allowing it to see these marks around the printing area. These marks are deposited by the device 101 as and when printing, using invisible ink except by the scanner. This scanner may illuminate the area with suitable light.
- the device 101 can then superimpose on the image that it prints marks invisible to the naked eye. With a sweeping step by step, the device knows its position at all times thanks to the marks printed during a previous and neighboring pass.
- the identification is initiated by a printed sheet pasted on the wall. This sheet has invisible markers except for the scanner. The position of this sheet in the image to be printed is known. It is therefore possible to start printing on this sheet and from there on the rest of the wall.
- the sheet is peeled off and its location is traversed by the device 101 so as to paint it.
- the location and the orientation are carried out by ultrasound. It then suffices to position 3 transmitters (501-503) in the room and two receivers on the device 101.
- the device 101 is then capable of determining the distance separating it from the 3 transmitters and therefore, by triangulation, of determining its position.
- a means is required to memorize the position of the transmitter (s) so as to be able to replace it or replace them in the same places to carry out repairs on the fresco. This memorization can be done by a nail planted in a specific place by example.
- the localization is carried out using a laser which scans the surface of the wall.
- This laser is detected at an instant t by the device 101.
- This instant t corresponds to a known position of the laser.
- This position is obtained by interrogating the laser emission device, via the means 308 for example.
- the laser draws on the wall 102 a grid similar to that described in FIG. 2.
- the orientation is determined by means of the sensor 316 which is capable of measuring a displacement relative to a known position. We are thus able, from a known initial position, to estimate the displacement carried out, and therefore the current location and orientation.
- the device 101 includes a scanner, it is possible to use the latter to acquire an image. This acquisition is carried out by moving the device 101 above the image that one wishes to acquire. This acquired image is then recorded, for example, in the memory 306. This acquired image can then be transferred to another wall, or recovered by a third-party device via the means 308.
- the projector 103 includes a shock detector making it possible to warn the operator when the latter has to reposition the grid. In this case the repositioning is equivalent to a readjustment as previously described.
- the 313 man-machine interface is located either on the body or on the handle. It comprises, for example, on / off buttons, a button for resetting the memory 315 to zero, a button for forcing printing independently of the content of the memory 315.
- This interface also includes diodes, and or sound means, making it possible to warn the operator of certain events such as a too rapid movement of the device on the wall, a low level of ink reserves, a displacement of the grid.
- a speed of movement of the device 101 is easily estimated either via the speed of rotation of the wheels 311, 312 and 317, or via the sensor 316, or via the sensor 303. These wheels and these sensors also give access to the acceleration of the device 101.
- printing can also be suspended so as to avoid imperfections in the transfer of the image if the means 307 cannot print in a manner compatible with the speed of movement of the device 101. The printing is also suspended if the operator stands between the sensor 303 and the grid.
- the dye tanks are either integrated into the device 101 or remote.
- the dye is then supplied via pipes connecting the reservoirs to the device according to the invention.
- the calculations and data extracts can be transferred, like memories 306 and 315, to a third-party device connected to device 101.
- either the image is cut so as to take it into account, or the device 101 is configured accordingly.
- This configuration is carried out, for example, by positioning the device 101 at the vertices of the zone to which the image is to be transferred. At each positioning at a vertex the operator presses a button, which allows the device 101 to define the printing area. This zone is located in the polygon defined by the vertices, and the printing is activated only when the device 101 is located inside this polygon.
- the device according to the invention is implemented by a robot which makes it sweep the wall.
