Technical Field
[0001] The embodiments herein generally relate to surface modification and finishing methodologies, and more particularly to an automated system and method which continuously modifies and enhances the surface properties of compatible materials.
Description of the Related Art
[0002] All existent operations related to the modification and finishing of any surface shall hereby be referred to as surface enhancements, in the context of the present invention.
[0003] A variety of surface enhancements exist to enable the modification of surfaces in both physical and visual senses, giving surfaces selective colour application, or, through selective additive or subtractive methods, giving the surface a physical texture. However, these enhancements are generally not dependent on the existing surface features (either visual or physical) of the surface.
[0004] Existing enhancement/modification methods are generally used separately and the material is transferred from one workstation to the next, where each workstation specifically deals with one method. Also, conventional system does not allow for much flexibility in a surface modification other than smoothening, roughening and tinting of color. Some existing technologies allow a custom print on a veneer but these are completely independent of original surface features and have less to do with enhancement and more to do with customization. The UV printing method on wood is a commonly utilized process, but not on the scale of mass production. The costs of UV printing process are also high. The UV printing yields a layer of ink which may or may not carry the original grain of the wood based on the type of grain carried by the same wood. The UV ink yields are of desirable color rendition but has very little penetration into the wood.
[0005] Three-dimensional CNC routing is another option to modify surface features. However, it is the most time consuming of all, and levels of detail are entirely dependent on the size of the router bit. Sand blasting is another option, but in order to achieve fine details, an equally detailed masking sheet may be made and applied to the surface. Sanding and wire brushing are also candidates for this process, but it is nearly impossible to achieve fine levels of detail, unless there is a masking sheet applied to the surface.
[0006] The incorporation of digital modification process for wood on large scale is desirable and has not been known. Further, a multi-functional system that can perform simultaneous functions including scanning and printing on substrates remains a major challenge, particularly in existing technologies.
[0007] Accordingly, there remains a need for a system and method in order to enhance/modify the surface digitally in correlation to its existing visual and physical features in real-time.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
[0036] The embodiments herein and the various features and advantageous details thereof are explained more fully with reference to the non-limiting embodiments that are illustrated in the accompanying drawings and detailed in the following description. Descriptions of well-known components and processing techniques are omitted so as to not unnecessarily obscure the embodiments herein. The examples used herein are intended merely to facilitate an understanding of ways in which the embodiments herein may be practiced and to further enable those of skill in the art to practice the embodiments herein. Accordingly, the examples should not be construed as limiting the scope of the embodiments herein.
[0037] As mentioned, there remains a need for a system and method for enhancing or modifying the surface of the material digitally in correlation to its existing visual and physical features in real-time. Referring now to the drawings, and more particularly to FIGS. 1 through 17, where similar reference characters denote corresponding features consistently throughout the figures, there are shown preferred embodiments.
[0038] FIG. 1 illustrates a perspective view of a surface enhancement system 100 according to an embodiment herein. The surface enhancement system 100 includes an image scanner 102, a workpiece material 104, an ink-jet printer head 106, workpiece thickness adjustment knobs 108, feed rollers 110, a set of adjustable pressure rollers 112A-B, a vertical fixed gantry 114A, a horizontal fixed gantry 114B, chassis 116, a slide plate 118, a drive motor unit 120, a drive pulley 122 and a drive belt 124. In an embodiment, the workpiece material 104 moves in forward direction on the slide plate 118 with the aid of the feed rollers 110 and the set of adjustable pressure rollers 112A-B. The image scanner 102 obtains digital image data periodically in real-time of the workpiece material 104. The digital image data are stored in a scan data buffer. In one embodiment, the image scanner 102 is fixed rigidly to a separate gantry.
[0039] The ink-jet printer head 106 moves along with the horizontal fixed gantry 114B from one end of work area on the workpiece material 104 to another end of the workpiece material 104 to enhance the surface of the workpiece material 104. The drive motor unit 120 moves the workpiece material 104, through the slide plate 118 and feed rollers 110.
[0040] The set of adjustable pressure rollers 112A-B are attached each side of the image scanner 102 in order to eliminate distortions in the captured image arising from warp in the workpiece material 104. In one embodiment, the image is captured through a linear image scanner, which may incorporate either CIS (Contact Image Sensor) or CCD (Charge Coupled Device) or any other suitable technology which require predetermined fixed distance between the workpiece material and the scanning device for accurate results. In one embodiment, image capture is achieved with a camera placed at a fixed distance from the workpiece material 104. However, this may not be ideal in practice, as the thicknesses of different materials are not constant, and the image capture result may vary in size due to change in distance from the workpiece to the camera, in the case of a fixed camera setup. Compensation for this enlargement or reduction in size may be achieved in image processing system or by adjusting the camera position vertically. It is also to be noted that materials with significantly uneven surfaces or warping may be partially out of focus. Another limitation of the camera based imaging system is the level of detail due to resolving power of the camera lens itself. Optical distortions may also have to be considered as a defining factor in terms of image quality. In another embodiment, it is these considerations that leads to line-by-line image scanning as the tentative ideal. Other, more suitable methods may also be used in case they are more compatible with the workpiece and environmental factors. The image capture method is not limited to contact image scanning. However, in the surface enhancement system 100, it has been used for its compatibility with the needs.
[0041] The surface enhancement system 100 further includes a system controller unit (not shown in FIG. 1). The system controller unit includes an image controller, and a print controller. The image controller includes a node-based digital image processor that is configured to modify the digital image data obtained by the image scanner 102 based on predefined effect definitions. The modified digital image data is stored in the scanned data buffer. The print controller receives modified image data for printing from the image controller and enhances the surfaces of the work piece material 104 using the inkjet print head 106. The modified digital image data for printing is stored in a print data buffer.
[0042] In one embodiment, the surface enhancement system 100 is operated in both real time and non-real-time to achieve a high-speed method of surface enhancement. In one embodiment, the workpiece material 104 is continuously driven through the surface enhancement system 100 in real-time operation without the need to stop or pause, other than the time needed for the inkjet print head 106 carriage to reverse direction once it has reached the end of its travel at either end of the horizontal fixed gantry 114B. In one embodiment, the slight delay is eliminated by replacing the movable inkjet print head 106 with a multitude of fixed print heads staggered along the width of the horizontal fixed gantry 114B, as an array, such that they cover the entire width of the workpiece material 104, and all the print heads may jet ink continuously as the workpiece material 104 moves beneath them.
[0043] The system controller unit may synchronize operations of scanner 102, and the ink-jet printer head 106 such that each system operates on a relevant part of the workpiece material 104 passing under it, therefore allowing for continuous movement of the workpiece material 104 through the system.
[0044] In one embodiment, the digital images are stored on a network based digital storage device. The system controller unit processes the digital images to extract features of the workpiece material 104 in each of the digital images. In one embodiment, the surface enhancement system 100 achieves multiple finishes (e.g. visual enhancement or physical modification) on one surface. In the surface enhancement system 100, screen printing and offset printing are not ideal, as the same print is to be repeated multiple times in these processes, whereas the required output in the surface enhancement system 100 is dependent on the existing visual features on the material, which may or may not change from one workpiece to another.
[0045] In one embodiment, in the case of non-real time surface enhancement, the material is held still, while the image scanner 102, and the ink-jet printer head 106 are attached to a sliding gantry which is able to move over the length of the workpiece material 104, and the surface enhancement system 100 perform their respective operations in succession.
[0046] In one embodiment, the surface enhancement system 100 utilizes a moving inkjet carriage, the inkjet carriage that actively interrupts motion of the workpiece material 104 through a machine, or the movement of the gantry in case it is a moving part, whose range of motion extends from one end of the workpiece material 104 to the other, lengthwise. The enhancement operations are performed exactly the same way as in the case of moving material. In case the gantry is a moving part, the material is placed on the system, processed, removed and replaced with the next piece of material.

[0054] FIG. 9 is a block diagram of the system controller unit 602 according to an embodiment herein. The system controller unit 602 includes the imaging controller 902, the print controller 904, the scanned data buffer 906, and the print data buffer 908. The image controller 902 includes the node-based digital image processor that is configured to modify the digital image data obtained by the image scanner 102 based on predefined effect definitions. The modified digital image data is stored in the scanned data buffer 906. The print controller 904 receives modified image data for printing from the image controller 902 and enhances the surfaces of the work piece material 104 using the inkjet print head 106. The modified digital image data for printing is stored in the print data buffer 908.
[0055] FIGS. 10A-10B are block diagrams of image capturing according to an embodiment herein. The block diagram includes the image scanner 102, the system controller unit 602, the imaging controller 902, the print data buffer 908, a storage 1002, a media drive motor 1004, an image bank 1006 and a node-based digital image processor 1008. The image scanner 102 scans the surface of the workpiece material 104 to obtain the scanned data. The modified digital image data is stored in the scanned data buffer 906. In one embodiment, the scanned data is stored. In one embodiment, the imaging controller 902 controls scanner operations including but not limited to synchronization of image capture with material/ gantry movement. The workpiece material 104 is continuously driven through such that the image scanner 102 continuously produces image data, one line or band at a time. This is relevant to CIS scanner technology. In this case, one line of image data consists an image spanning the width of the material, one pixel in height. A multitude of these lines placed successive in rows would define a band. In the case of CCD technology, the native form of data output from the scanner would be a band, as each CCD sensor module captures a 2-D image, which is then digitally stitched to the image captured from the adjacent CCD. In either case, the image data is stored in the scanned data buffer 1008, and may optionally be stored in the storage 1002, which may be a disk drive. The node-based digital image processor 1008 reads data from the scanned data buffer 906, which is sent by the imaging controller 902. The node-based digital image processor 1008 applies modifications to the image data based on pixel manipulation algorithms, which allow for localized displacement of pixels based on hue/saturation or brightness of the pixels, and also on color adjustment algorithms, which allow for various existing effect definitions to be applied, such as but not limited to blurring, sharpening, color washes, brightness/contrast adjustments, color shifts, etc. These modifications may optionally be driven by secondary image data from another source such as the image bank 1006. The node-based digital image processor 1008 outputs 3 streams of data. Storage, which may be a hard disk or equivalent archival memory device, optionally receives color image data, intended for the print data buffer 908. Storage is accessed by the image bank 1006 function, such that stored image data may be re-used in the processing of new image data from the scanned data buffer 906. In on embodiment, image bank 1006 function also access images on other memory devices.
[0056] FIG. 11 illustrates a memory usage of the surface enhancement system 100 according to an embodiment herein. In one embodiment, effect definitions are pre-defined before the invention is put into operation, and are located in effect definition (node set) from database/list, which in turn is located on a storage device, and may be modified as required. The print data buffer 908 hold relevant bands of image data, that are utilized by the respective modules print head(s). Each physical, widthwise line on the surface of the workpiece material 104 has a corresponding line of digital image data in the print data buffer 908, which is constantly shifted downwards as the material progresses through the machine. The data is only retained until its corresponding operation is fulfilled, and is discarded, line-by-line, or band-by band, to free up space for new image data that is received from the node-based digital image processor 1008, as the print data buffer 908 have a predefined storage capacity. In one embodiment, the new image data is added to the top of the band stored in both buffers. The node-based digital image processor 1008 may compute image modifications based on neighboring pixels, the maximum size of pixel neighborhood being the distance between the image scanner 102 and the ink-jet printer head 106 in the case of print image data processing. The entire imaged width of the workpiece material 104 is available for sampling in both cases.
[0057] FIG. 12 is a block diagram of the print controller 904 of FIG. 9 according to an embodiment herein.

The print controller 904 may receive instructions or feedback from the printer interface 1204 or the printer control board 1206. The print controller 904 receives print data to further process to the raster image processor 1202. The function of these components has been described above.
