Definitions
- the present invention relates to a method for creating a three-dimensional documentation for a commodity, which consists of several parts.
- Documentation such as Manuals, operating instructions, assembly instructions, repair instructions, training documents, etc., for various consumer goods, from household appliances, toys, machines and machine components to highly complex technical equipment, are in most cases available in printed form, or in a digital equivalent, for example as a pdf file or html file.
- Such documentation generally contains various two-dimensional illustrations of the article of daily use, by means of which a user of the article of daily use is to grasp the function of the article of daily use or by means of which the user receives instructions for using the article of daily use.
- An illustration may be a simple view or an isometric drawing or a photograph of a view of the commodity.
- Such illustrations in printed documentations are necessarily two-dimensional representations of different views of the everyday object. The user of the commodity must therefore use the documentation two-dimensional views on the real three-dimensional commodity move, which is a quite complex mental challenge and is a problem for many people due to the lack of or little spatial imagination.
- Augmented Reality is generally understood, the real sense perception of a person of reality, especially what is seen, heard or felt to expand or supplement additional information. This additional information can also be conveyed to a person visually, acoustically or haptically.
- the commodity with a recording unit such as a digital camera of a smartphone or a tablet PC, a 3D scanner, etc.
- a recording unit such as a digital camera of a smartphone or a tablet PC, a 3D scanner, etc.
- recorded and expanded the view of the utility object in real time with additional information expanded by these eg displayed on the captured and displayed image or by playing an acoustic information.
- This also automatically takes place an adaptation of the representation when changing the relative position between the receiving unit and the utility object.
- augmented reality There are already approaches to realize the documentation of everyday objects in three dimensions, also with augmented reality.
- the creation of a three-dimensional documentation of a commodity is a very complex and time-consuming task, especially if it still three-dimensional animations, possibly in real time (as in augmented reality) is desired.
- This object is achieved according to the invention by determining image parameters of at least one image of the commodity in an existing two-dimensional documentation, bringing a 3D model of the commodity with the determined image parameters into coincidence with the image, and comparing the two-dimensional image and the image 3D model with the determined image parameters from the two-dimensional image additional information is obtained, forms together with the SD model, the three-dimensional documentation of the commodity.
- This procedure makes it possible to analyze images in existing two-dimensional documentation in order to obtain additional information that can then be displayed in any view of the 3D model. It does not matter whether the two-dimensional documentation is in the form of an already existing printed documentation with two-dimensional imaging that can be used for the method according to the invention, or whether the two-dimensional documentation is recreated only for the creation of three-dimensional documentation.
- a plurality of corresponding points are selected in the image and in the 3D model and the image parameters are varied until the image and the 3D model overlap.
- a suitable criterion for determining a sufficient coverage can be determined.
- related components are determined in the figure, the eccentricities of the connected components are determined, and the determined eccentricities are compared with a predefined threshold value in order to determine at least one candidate for a guide line.
- a line is placed representing the guide line and based on a mask obtained from the 3D model of the commodity determines which end point of the straight line is in the commodity.
- This method can be implemented automatically by means of digital image processing, whereby guide lines can be easily identified as additional information. If a search region is defined around the other end point of the straight line, which is examined by means of a character recognition software for note text, the existing note text assigned to the guide line can also be determined automatically and preferably stored assigned to the guide line.
- the straight line can advantageously be realized by placing in the contiguous component of the candidate an ellipse whose main axis (as a straight line) lies in the direction of the longitudinal extent and whose vertices represent the end points of the determined guide line. This allows a very stable algorithm to be realized.
- the end point of the straight line which lies within the article of daily use, is assigned to a part of the article of daily use.
- the guidance line can be anchored to the correct part in every view of the object of use.
- the movement possibilities of at least a part of the commodity is advantageously determined by a method for motion planning. This too can be easily implemented using existing methods.
- coherent components can be determined in the figure, wherein at least one coherent component is determined that has characteristic features of a movement arrow. For a translational movement arrow, this is done in a simple manner by determining at least one coherent component whose circumference has exactly two concavities. Again, an ellipse having a major axis in the longitudinal direction of the contiguous component may be fitted to the contiguous component, with a vertex of the ellipse closer to the concavities being interpreted as the apex of a motion arrow. This can be a desired direction vector of a part of the commodity determine.
- This information can be advantageously used by using the determined movement arrow to an implied movement of a part of the commodity is concluded and based on the motion planning at least a part of the commodity is determined, which can perform this movement.
- additional information can Here you can determine which parts can be moved on the real object of daily use.
- views can be created in which a part of the commodity is moved and / or shown twisted.
- the position of at least part of the utility object in the 3D model can also be varied until the image and the 3D model sufficiently overlap.
- the type and the distance of the movement of the part can be obtained here.
- exploded views can be displayed as views of the commodity.
- two images of the utility object can be examined, wherein a first image differs from a second image by at least one added, removed or repositioned part of the commodity and a part in the 3D model based on the movement possibilities determined from the movement planning is added, a part in the 3D model is removed or the position of at least one part in the 3D model is varied to get from the first image to the second image.
- This additional information can be used particularly advantageously for a representation of a sequence of actions to be set on the commodity, preferably in the form of a series of views of the commodity.
- the two maps can first be used to determine the differing regions and to investigate the possibilities of movement of only those parts which lie in the differentiating regions.
- 1 and 2 show the procedure for determining the image parameters of an image of a two-dimensional documentation
- FIGS. 14 to 16 show the method in a concrete example.
- an arrow is added in a two-dimensional image of a view of the utility object, which indicates a (translational or rotary) movement of a part of the commodity that is to be implemented by a user on the commodity.
- This type of representation is often used in operating, service or repair instructions to indicate to a user how to use a part of the commodity.
- a sequence of two-dimensional images of the commodity is generally depicted, each image being differentiated from its predecessor or successor by at least one part that has either been added, removed, or changed in position relative to other parts. Often added, removed or repositioned parts are also provided with guide lines or arrows to indicate the intended attachment point to the commodity.
- the various figures often show an identical view of the commodity in different configurations. This style of display is commonly used in assembly or disassembly instructions to give the user step-by-step instructions for action.
- the two-dimensional documentation may be in the form of pre-existing printed documentation with two-dimensional imaging, typically in the form of manuals, user manuals, assembly instructions, repair instructions, training materials, etc.
- the two-dimensional documentation for the preparation of Re-create three-dimensional documentation first.
- the article of daily use could be photographed in various views and configurations prior to application of the method of the invention and the photos used as two-dimensional images. Both are understood as two-dimensional documentation within the meaning of the present invention.
- the present invention is based thereon, from an existing conventional two-dimensional documentation of a commodity 1 in printed form (or in digital equivalent as a computer file) largely automated to create a three-dimensional documentation of this commodity 1, which then, for example, for an augmented reality application for a Web-based training or for animated documentation can be used.
- at least one existing image A of the everyday object 1 in the two-dimensional documentation 2 is analyzed and information for a three-dimensional documentation is obtained therefrom.
- the figure A in the documentation 2 is available in digital form, for example, in that the image A of the documentation 2 is scanned in two dimensions with sufficient resolution or the documentation 2 is already present in digital format. In this case, a resolution corresponding to the level of detail of the image is usefully chosen.
- a prerequisite for the method according to the invention is that a digital 3D model M of the utility article 1 is present.
- the digital 3D model M can be present, for example, in the form of a 3D-CAD drawing.
- the documentation 2 is usually created by the manufacturer of the utility item 1 and in the present time, the development and construction of the commodity 1 by means of or by means of 3D drawings is common, in most cases, such a 3D-CAD drawing will be available.
- a 3D CAD drawing has the advantage that all parts are included and identifiable.
- the utility article 1 could also be used to make a 3D scan.
- individual parts of the everyday object 1 could be individually scanned three-dimensionally and subsequently joined together to form a 3D model of the article of daily use 1.
- 3D scanners and associated software are available, which allow to make such 3D scans.
- Kinect® sensor from Microsoft® in combination with the open source software package KinFu.
- the two-dimensional image A of a view of the utility article 1 was created in the printed documentation 2, regardless of whether the image A is a photograph or a drawing .
- the two essential image parameters are the viewing position in space with respect to the commodity 1 and the focal length, with the commodity 1 was considered.
- the image changes when the viewing position of the camera is changed to the commodity 1 or when the camera settings, in particular the focal length, is changed.
- a plurality, preferably four or more, of corresponding points P1A-P1M, P2A-P2M, P3A-P3M, P4A-P4M are marked, as indicated in FIG.
- Corresponding points P1A-P1M, P2A-P2M, P3A-P3M, P4A-P4M are identical points of the commodity 1 in Figure A and in the 3D model M. It is needless to say that the points P1 A, P2A, P3A , P4A in the illustration A of the utility item 1 are shown.
- the focal length is estimated as the image parameter if, as is usually the case, it is not known.
- the corresponding points P1A-P1M, P2A-P2M, P3A-P3M, P4A-P4M and the estimated focal length, the viewing position BP which has led to the view A of the utility article 1, by means of available and well-known Algorithms of digital image processing, such as the known POSIT algorithm, are determined.
- the image A and the view of the 3D model M with the determined viewing position BP1, for example by displaying them together on a screen, the result can be checked, as shown in FIG.
- the focal length can be changed and / or other or further corresponding points can be selected. This can be iteratively repeated until there is a sufficiently accurate coverage of the image A with the view of the 3D model M at a determined viewing position BPn (FIG. 2, right).
- the determination of the viewing position BP can be easily determined by a user, whereby the user himself decides when sufficient coverage has been achieved.
- the viewing position BP can equally well be automated with the aid of standard methods of digital image processing, such as methods for point identification and for determining image coverage.
- the focal length can also be changed iteratively in an automated manner until the best possible image coverage and thus the desired viewing position BP, which has led to the image A, results.
- the determination of the viewing position BP can be repeated for each two-dimensional image A of the printed documentation 2 of interest. Often, however, it is the case that all images A of the printed documentation 2 were created with the same image parameters. Therefore, it may also be sufficient to determine the image parameters only once and then to apply to all images A of interest, or at least some of them.
- the map A After covering the two-dimensional map A in the printed documentation 2 and the 3D model M as described, the map A can be analyzed with respect to the above representations.
- the basic procedure is such that additional information is obtained from the comparison of the two-dimensional image and a view of the 3D model with the determined image parameters from the two-dimensional image, which information is then displayed in a view of the 3D model of the object of use. Standes, in the form of a view of the 3D model, can be displayed.
- the additional information is preferably assigned to individual parts of the everyday object 1, so that the additional information can always be displayed correctly in the respective view even when changing the view (eg when the SD model M is rotated in space).
- a two-dimensional mask S (FIG. 3, right) is created, which contains all the pixels of the determined view of the 3D model M.
- the mask S With the mask S, all pixels of the digitized image A (which is in coincidence with the view of the 3D model M) can now be determined, which lie outside the view of the commodity 1.
- related components are now searched for in the digitized image A.
- MSER Maximally Stable Extremal Regions
- Component K thus comprises a number of pixels (indicated by the points in FIG. 4) of the digitized image A.
- coherent components K those which can represent a guide line 3i, 3 2 in FIG.
- the eccentricity of the connected components K can be determined.
- the eccentricity is defined here as the ratio between the greatest longitudinal extent and the greatest transverse extent (normal to the longitudinal extension) of the contiguous component K.
- a corresponding threshold can be defined.
- Each contiguous component K1, K2, whose eccentricity exceeds this threshold and the outer boundary of the mask S intersects, or at least touches, (as a guide line 3i, 3 2 must point to a part of the utensil 1) is interpreted as a guide line 3i, 3 2 (Fig.4).
- the end points E1 1, E12 of a guide lines 3i, 3 2 are to be determined.
- any method can be used in order to best fit a straight line in the pixels of the contiguous components K1, K2 in the direction of the longitudinal extent.
- an ellipse with a major axis H in the direction of the longitudinal extent can be fitted around the pixels of the connected components K1, K2, as indicated for the components K1 in FIG.
- the vertices of the ellipse on the major axis H are then interpreted as endpoints E1 1, E12 of the desired guide line 3i. Based on the mask S can now be easily determined which end point E1 1, E12 are in the range of the commodity 1 and which outside.
- the end point E12 within the article of daily use 1 it is also possible to ascertain on the basis of the 3D model M that the determined guide line 3i points to the soft part of the article of daily use 1.
- This assignment can also be stored in a separate parts memory containing all individually identifiable parts of the commodity 1.
- the determined end point E12 within the article of daily use 1 is stored as an anchor point AP1 (FIG. 5) of the guide line 3i for the three-dimensional documentation, optionally together with the assignment to a specific part of the article 1 in the parts store.
- anchor point AP1 can also be laid in the respective body center of the associated part T, which may be advantageous for a later three-dimensional representation of the article of daily use 1.
- a search region SR (FIG. 4) which is searched for text or numbers, for example by means of conventional character recognition (OCR) software, can now be defined around the end point E1 1 which lies outside of the article of daily use 1.
- OCR character recognition
- an annotation text could also be manually added to the determined guideline 3.
- the comment text thus determined is likewise stored for the guide line 3i, for example again in the parts memory.
- the view of the commodity 1 is changed, e.g. the camera position for receiving the utility item 1 is changed
- the insertion of the determined guide line 3i and the associated annotation text can be retraced by the fixed anchor point AP1 accordingly.
- the anchor point AP1 thereby remains on the identified part of the commodity 1 and the other end point E1 1 of the guide line 3i with the annotation text can be positioned in the augmented reality display at any desired location, preferably a location outside the commodity 1, as in Fig.5 shown.
- the guide line 3 with annotation text can, of course, be displayed in any three-dimensional view of the utility item 1.
- Figures with movement arrows Fig.6 to 8
- parts T of the commodity 1 is first to determine which parts T are individually movable at all.
- This information can either already be contained in the 3D model M or can be determined by known methods. Such methods are known in particular from the field of motion planning of components. In this case, it is examined which parts T1, T2 of the object of daily use 1 are moved in the 3D model M (translational and / or rotational) can and if so, in which area, without colliding with other parts of the commodity 1.
- both a possible direction vector RV1 (or several possible direction vectors) of a translatory movement or a rotation axis (or several possible axes of rotation) of a possible rotational movement are determined, as well as the possible distance D of the movement, as in FIG indicated for a translational movement.
- a method for this is eg in Lozano-Perez, T., "Spatial planning: A configuration space approach", IEEE Trans. Comput. 32, 2 (Feb. 1983), p.108-120.
- the information of the determined possible movements is stored for each part T1, T2 of the 3D model M, for example again in the parts memory.
- the motion arrows P in Figure A are to be identified, as exemplified by Figure 7.
- an ellipse with a major axis H is again adapted to the coherent component K, the major axis H being oriented in the direction of the longitudinal extension of the contiguous component K. That vertex of the ellipse closer to the concavities V1, V2 is interpreted as the peak SP of the movement arrow P. The other vertex is then the base B of the movement arrow P. From the main axis H of the ellipse, as well as base B and tip SP (or one of the two), a directional vector RV of an intended movement of a part T1, T2 of the commodity 1 can be determined. Now it is still necessary to determine which part T1, T2 of the commodity 1 is to be moved.
- the parts T2 that can be moved in the direction of the direction vector RV are determined.
- the parts T2 are searched whose direction vector RV1 of the possible movement (from the motion planning method described above) coincides with the direction vector RV of the movement arrow P.
- a spatial angle range ⁇ is usefully set by which the two directional vectors RV, RV1 may deviate, as indicated in FIG.
- movement arrows P which represent a rotational movement, it is possible to proceed analogously. So first identification of the movement arrow P and the desired rotation (or rotation axis), and then determining the parts that can perform the rotation.
- a movement arrow P can then be superimposed, for example in a recorded real view of the utility object 1, and an animation is started when the movement arrow P is clicked, which animates the movement of a part T2 of the commodity object 1 over the receptacle of the utility object 1. Again, the animation can be retraced when changing the viewing position in real time.
- Exploded views FIGS. 9 to 10.
- the method described above can be used e.g. only on a part T2 of the exploded view ( Figure 9), preferably a main component applied.
- the determination of the possible movements of the parts T of the utility article 1, as described above, is at the beginning.
- the determined image parameters BP for the image A of the exploded view see above
- the movable parts T of the commodity 1 in the 3D model M are varied according to the determined possibilities of movement, ie different positions of the movable parts T are assumed (FIG. and in each case checked to what extent the image A and the respective view of the 3D model M coincide with the determined image parameters BP.
- Standard methods of digital image processing can also be used again. Basically, any algorithm for varying the possible motions can be implemented. Examples are found in Agrawala, M., et al., Designing effective step-by-step assembly instructions, ACM Trans. Graph.
- the goal of the algorithm implemented should of course be performance, in order to obtain more complex objects 1 with many parts T
- FIG. 1 a montage sequence of parts T1, T2, T3 on the article of daily use 1 is shown by way of example with the figures A1, A2 of the documentation 2.
- the part T2 with part 3 is arranged on the part T1.
- a reverse assembly planning starting with the fully assembled commodity 1 will be applied.
- the starting point here is again the image A and the 3D model M brought into coincidence with it.
- the motion possibilities of the parts T are examined and the parts in the 3D model M are varied until the best possible coverage is found ,
- the 3D model M is advantageously reduced to the parts which are contained in the figures A1, A2, which is possible in each case using the reverse order.
- regions R of the figures A1, A2 can be examined, in which changes have taken place (FIG. 12). These regions R can be found, for example, by determining a pixel-by-pixel difference in the illustrated sequence of Figures A1, A2. If the figures A1, A2 show the parts T1, T2, T3 chig filled with different colors, which is often the case, the region R of the change can be determined simply by pixel-wise subtraction and thresholding (to eliminate possible slight differences). As a pixel-by-pixel subtraction here is the subtraction of the color values of each pixel understood, resulting in a difference between the images.
- images A1, A2 For simple line drawings as images A1, A2, which is also often the case, the images A1, A2 can be improved beforehand, in which first the silhouettes of Figure A1, A2 (ie the outer border) are determined and then the background of Figure A1, A2 outside the silhouette can be filled with a uniform color.
- images A1, A2 other methods of digital image processing can be used to locate the changing regions.
- SIFT scale-invariant feature transform
- a complete sequence of a structural representation can then be animated.
- a montage or disassembly sequence can be displayed in a recorded representation of the utility article 1.
- the methods described above and the procedure for analyzing a picture 2 of a documentation of a commodity 1 is again clearly shown in FIG.
- the starting point is the 3D model M and a two-dimensional image A of a view of the object of utility 1.
- Information about the individual parts T of the object of use 1 can be stored in a parts memory TS, eg a unique identification of each part T.
- the first step S1 determines the image parameters BP.
- the notes x, y and the guide lines 3 are determined in step S2 and optionally stored in the partial memory TS (possibly with the anchor points AP) to the respective parts T.
- a movement planning of the parts T of the utility article 1 is provided in step S3. hen.
- the possibilities of movement (direction vector RV and / or rotation axis) of each part T are again stored in the parts memory TS.
- the movement arrows P are identified in step S4 and assigned to certain parts T of the utility item 1, which is again stored in the parts store TS.
- the described algorithms for image comparison are used in step S5. Again, the information obtained EX1 (shift, rotation of certain parts T) is partially stored in the parts memory TS.
- step S6 algorithms for the analysis of regions R with changes can also be used in step S6 in order to obtain the information EX2 of the changed parts T between two images A1, A2.
- the steps S1 to S6 are also carried out in combination, so that combinations of different images 15 can also be analyzed.
- the result is a three-dimensional documentation 10 of the article of daily use 1 which can be adapted as required, for example with annotations (01), as an animation of a movement of a part T on the basis of identified movement arrows (02), as an exploded view (03), as an assembly sequence ( 04) or as any combination of the possibilities described above (05).
- the information from the parts memory TS can be used.
- FIGS. 14 to 16 this will be described on a concrete example in the form of a documentation 2 for a filter.
- a first figure A1 the filter with the three parts housing T1, screw T2 and T3 filter insert is shown, wherein the three parts T1, T2, T3 also comments and guidelines are included.
- the illustrations A2 and A3 describe a filter change with a sequence of images in the form of a structural representation.
- the screw cap T2 is shown removed from the filter housing T1 in Figure A2 and indicated the necessary action (unscrewing the lid) by a movement arrow P1.
- the filter insert T3 is shown removed from the filter housing and the necessary action for it is again indicated by a movement arrow P2.
- These images A1, A2, A3 can be analyzed as described above to create a three-dimensional documentation 10, which in turn can be reused, e.g. in an augmented reality application.
- the article of daily use 1 is first digitally recorded, eg by means of a digital camera, 3D scanner, etc., and then the 3D model M is brought into conformity with the recorded view of the article of daily use 1. This can either be done manually or using known algorithms, such as the SAC-IA (Sample Consensus Initial Alignment) algorithm. algorithm.
- SAC-IA Sample Consensus Initial Alignment
- the recorded view of the commodity 1 can then be enriched as needed with the information obtained from the analysis of the documentation 2 described above.
- annotations obtained from the printed documentation 2 can be displayed in the respective real view of the article of daily use 1.
- the guide line 3 is represented starting from the anchor point AP so that the annotations can be displayed optimally.
- the annotations may be dragged along.
- Explosion or structural representations in augmented reality may also be user-controlled, e.g. by the user indicating which or how many parts are displayed in an exploded view.
- the representation of the augmented reality can be reproduced either in completely rendered representations, or only the outlines above the recorded image of the commodity 1 can be displayed.
- computer goggles can also be used, with which the article of daily use 1 is filmed and superimposed on the previously obtained additional information on the object of daily use 1 as required in the field of vision of the wearer of the computer goggles.
- the obtained three-dimensional documentation 10 can also be used in a virtual reality viewer, e.g. for training on the utility object 1.
- various views of the 3D model M can be represented, which can be enriched by the additional information obtained or in which the commodity 1 in various representations, e.g. in an exploded view, is shown.
