Description

The present application relates to a device for the physical, in particular for the optical detection of at least one usage object and a corresponding device.

Previous devices for assigning a usage object to a usage object class are inexpensive, but quite imprecise.

As a rule, a photograph of an object in use is taken for this purpose in order to be able to identify this on the basis of its structural and / or haptic features. A database was often used for this purpose in order to compare the usage object depicted in the photograph with usage objects stored in a database, but this comparison was often incorrect and imprecise, since the comparison often depends on optical and / or technical details. One aim of the present application is to avoid such inaccuracies and / or errors that occur in the comparison process between the recorded usage object and a usage object stored in the database.

A solution to the above problem is therefore the claimed and presented claim 1.

It is therefore an object of the present invention to offer a device for the physical, in particular for the optical detection of at least one usage object, which is not only cost-effective and time-saving, but also has a particularly high level of accuracy in the comparison between a usage object and a usage object stored in a database forms in order to be able to uniquely, preferably unambiguously identify a usage object.

According to at least one embodiment, the device presented here for the physical, in particular for the optical detection of at least one usage object, comprises at least one provision of a usage object, at least one processing unit, by means of which a usage object and / or an identification means assigned to the usage object can be physically detected, preferably one-to-one, from which at least one characteristic value of the usage object can be obtained, and further wherein the processing unit and / or a CPU is set up and provided to carry out a usage object classification insofar as a characteristic value of the usage object can be obtained with at least one in a database of the processing unit and / or with a database is comparable to an external CPU, and the processing unit and / or the CPU and / or the user himself selects a database object corresponding to the characteristic value and displays the processing in a screen unit so that a camera image of the usage object together with the database object can at least partially be visually superimposed on the screen and / or displayed next to one another,

According to the invention, by means of the processing unit and / or the CPU, at least one physical acquisition process, in particular at least one photograph, of the usage object can be carried out on the basis of the database object depicted on the screen, so that the user records the usage object in such a way that an image of the usage object recorded by the acquisition process Usage object is displayed identically or scaled identically to the database object shown on the screen, whereby the usage object can be assigned to at least one usage object class, for example a vehicle type, by the processing unit and / or the CPU and / or the user.

The usage object can generally be an object, in particular a three-dimensional object, which is supplied or to be supplied to or contained in a use. The term "use" in the sense of the registration means any handling with regard to a purpose.

The processing unit can be a computer and / or storage unit. The processing unit is preferably also set up and provided for taking photographs. For this purpose, the processing unit can have at least one camera or at least part of a camera. For example, the usage object is designed to be portable, which means that the usage object cannot be connected to a floor or to a handling device connected to the floor element. In the context of the invention, “portable” can mean in particular that the processing element has such dimensions and such a weight that it is set up and intended to be held by hand, in particular with one hand. As an alternative to this, the processing unit can also be detachably or permanently connected to a floor on which the usage object is set up. Such a connection can be established via the handling device described above. In this embodiment, the processing unit can be guided along guide paths, for example along at least one rail or a rail system relative to the object of use.

wobei die Werte K1 bis K3 die jeweiligen Teilwerte darstellen und die Faktoren G1 bis G3 (welche reelle positive Zahlen darstellen) jeweilig Gewichtsfaktoren der Teilkennwerte bezeichnen. Bei der hier vorgestellten Nutzungsobjektklassifikation kann es sich um einen rein optischen Vergleich zwischen dem mit einer obig genannten Kamera aufgenommenen Nutzungsobjekt und einer in optischer Weise entsprechend hinterlegten Nutzungsobjektvorlage in einer Datenbank handeln.The characteristic value can be a real number greater than 0, but it is also conceivable that the characteristic value is composed of various partial characteristic values. A usage object can therefore have a partial characteristic value with regard to an exterior color, for example, with regard to maximum dimensions in height and width and / or depth a further characteristic value, and with regard to weight a further partial characteristic value. For example, such a characteristic value can therefore be formed by combining these three partial characteristic values. A combination can take the form of a sum or a fraction. However, the characteristic value is preferably determined in the form of a sum of the aforementioned partial characteristic values. However, the individual partial parameters can also be included in the summation with different weightings. For this purpose, it is conceivable that each partial parameter has a first weight factor as a weight factor, the second partial parameter with a second weight factor and a third partial parameter with a third weight factor according to the formula: $$\text{K}=\text{<figure-callout id="1" label="G" filenames="DE102019110344A1\_0002.png,DE102019110344A1\_0003.png" state="{{state}}">G</figure-callout>}1*\text{<figure-callout id="1" label="K" filenames="DE102019110344A1\_0002.png,DE102019110344A1\_0003.png" state="{{state}}">K</figure-callout>}1+\text{<figure-callout id="2" label="G" filenames="DE102019110344A1\_0002.png,DE102019110344A1\_0003.png" state="{{state}}">G</figure-callout>}2*\text{<figure-callout id="2" label="K" filenames="DE102019110344A1\_0002.png,DE102019110344A1\_0003.png" state="{{state}}">K</figure-callout>}2+\text{<figure-callout id="3" label="G" filenames="DE102019110344A1\_0002.png" state="{{state}}">G</figure-callout>}3*\text{<figure-callout id="3" label="K" filenames="DE102019110344A1\_0002.png" state="{{state}}">K</figure-callout>}\mathrm{3,}$$

whereby the values K1 to K3 represent the respective partial values and the factors G1 to G3 (which represent real positive numbers) respectively designate weighting factors of the partial characteristic values. The usage object classification presented here can be a purely optical comparison between the usage object recorded with a camera mentioned above and a usage object template stored in a database in an optically corresponding manner.

However, it is also possible for the usage object to be divided into individual object classes in terms of data or to be able to be categorized. In this respect, instead of an (analog) and optical comparison between the recorded usage object and the usage object stored in the database, a data-related, for example analog, comparison is made. The usage object is therefore broken down into individual data, for example data classes, by a conversion unit, which is then compared individually or jointly with data or data classes correspondingly stored in the database.

The data object can accordingly be a template image of the corresponding usage object stored in the database. Once the characteristic value of the usage object has been determined, it can be conceivable that the corresponding database object, which can optically depict the usage object, is selected on the basis of the characteristic value in order to be displayed on the screen next to the usage object actually recorded.

According to at least one embodiment, the processing unit is set up and provided that a recording process is carried out, for example, by a user and / or an implementation device of the usage object, so that the usage object is recorded in such a way that an image of the usage object recorded by the recording process is identical or scaled identical to the database object displayed on the screen. “Identical” in this context means a closest approximation to a usage object stored in the database using the characteristic value and / or the optical dimensions of the usage object. This can mean that the usage object, which can be detected by the processing unit, does not correspond in all dimensions and wear and tear to the usage object identified in the database according to the characteristic value, but the greatest correspondence is established on the basis of predetermined minimum dimensions.

It is conceivable that the usage object is a vehicle, for example a 3 Series BMW. The usage object itself can, for example, have a spoiler and / or be set lower. If a corresponding usage object is not stored in the database with an additional spoiler and a lower version, but the database only generally has a basic model of a 3 Series BMW, the processing unit and / or the database and / or the external CPU can still use this Select the basic 3-series model as the closest match to the usage object, for example because the characteristic values of the usage object are identical, for example based on a vehicle sticker.

With the above-mentioned usage object classification in conjunction with the corresponding implementation based on the physical acquisition process, the acquisition process can result in the usage object being assigned to at least one usage object class by the processing unit and / or the CPU and / or the user, for example a vehicle type becomes.

As already described above, the vehicle type can be, for example, a BMW of the 3-series or any other vehicle approved on German roads or the international road system.

According to at least one embodiment, the physical acquisition process comprises at least one temporal acquisition sequence, where at least two different recordings of the usage object are carried out during the acquisition sequence, each recording being assigned to at least one database object.

For example, the acquisition sequence records instructions to an implementation device and / or to a user to photograph the usage object at different angles, different distances with different color contrasts or the like in order to simplify identification with a usage object stored in the database.

According to at least one embodiment, after the characteristic value acquisition and for the usage object class identification on the screen, at least one chronologically sequential acquisition instruction of the temporal acquisition sequence for acquiring at least two recordings takes place. In particular, the processing unit is set up and provided that this lateral detection sequence is followed. The acquisition sequence can therefore have precise instructions to the user and / or an implementation device with regard to the location, the exposure brightness or the like, so that the processing unit, which preferably comprises an optical camera, optically fends off the object of use along predetermined points.

For more precise orientation at special orientation points of the usage object, at least one, but preferably a plurality of orientation points, preferably also detachably, can be attached to the usage object. Such orientation points can be marking elements which the camera of the processing unit can record particularly easily. For example, the marking elements are barcodes or barcodes and / or NFC chips.

Such marking elements can therefore also be passive components. However, it is also conceivable that such marking elements can be releasably applied to the usage object, for example glued on. Such usage objects can have their own energy supply, for example a battery supply. Such marking elements provided with a battery can emit electromagnetic rays in the optically visible or invisible, for example infrared or microwave range, which can be detected by a locating element of the processing unit and whereby the processing unit is able to determine the position in which it is is relative to the usage object.

Alternatively or additionally, however, it is also conceivable that the marking elements are virtual marking elements which are loaded from the database and which, like the usage object itself, from the database as an image, for example as a third image together with a photograph of the usage object and accordingly virtually from the Database-loaded appearance of the usage object can be displayed on the screen of the usage object, as can the database objects (which can map the usage objects in a virtual sense and which are stored in the database), as well as further database objects in the database of the processing unit and / or the external CPU. For example, with one and the same characteristic value, both the usage object and the further database object (at least one marking element) can be loaded together into the processing unit and / or displayed on the screen of the processing unit.

According to at least one embodiment, the chronologically sequential version instructions give the user a detection distance and / or a detection angle relative to the object of use.

As already mentioned above, the recording instructions therefore provide a precise schedule, preferably in a fully automatic manner with regard to the recording of the individual images, in particular photographs of the objects in use.

According to at least one embodiment, the characteristic value is taken and / or can be removed, in particular scanned, from an identification means, for example a usage badge of the usage object. The characteristic value is therefore also preferably recorded fully automatically by the processing unit, which has an optical camera, for example. It is preferably no longer necessary for the user and / or the implementation device to have to enter the characteristic value manually into the processing unit.

According to at least one embodiment, the processing unit comprises or is a smartphone or a camera. If the processing unit is a smartphone or a camera, it can, as already mentioned above, be manageable.

According to at least one embodiment, the processing unit is attached to a receiving element which moves relative to the object of use in accordance with the specifications through the acquisition sequence. The processing unit can therefore move together with the receiving element in accordance with the detection sequence relative to the usage object. In such a case, the processing unit can be or comprise a smartphone or a camera and the processing unit can nevertheless also be a manageable processing unit. However, this is attached to a larger unit, namely the receiving element. Preferably, the receiving element comprises all the necessary components to be moved fully automatically or by manual force of the user along the usage object.

According to at least one embodiment, the recording element is a drone which is steered relative to the object of use in accordance with the detection sequence in order to be able to take the individual recordings preferably along or on the above-mentioned marking elements.

In the context of the invention, a “drone” can be an unmanned vehicle, preferably an unmanned aircraft with one or more helicopter rotors. The drone can then be controlled wirelessly or wired via a control device by the user and / or by the implementation device manually or also fully automatically and thus steered.

By means of the drone it is possible to the extent that a very space-saving procedure can be used when recording the object of use around the object of use. In particular, it is possible to dispense with a safety distance between the object of use and other objects of use, for example other cars in a car showroom, so that the drone preferably moves hovering over the individual positions to be photographed in accordance with the determination sequence, without having to drive very far away other objects of use that are not involved. The drone would then simply approach the object of use from above and, for example, also drive into the interior of the car in order to also be able to take indoor photos.

According to at least one embodiment, the acquisition sequence also includes control data on the flight altitude of the drone, so that the drone flies off the acquisition sequence from the side, preferably fully automatically. If, for example, a certain acquisition sequence, which can be specified by the user and / or implementation device, is called up by the processing unit on the basis of the above-mentioned marking elements, a fully automatic process can run, at the end of which the unambiguous or preferably the unambiguous identification of the usage object with a can be used object stored in the database.

It is generally pointed out that features formulated on the process side in the application are also to be regarded as disclosed on the device side, and vice versa.

Further advantages and embodiments emerge from the accompanying drawings.

• 3A -3E eine weitere Ausführungsform der hier beschriebenen Vorrichtung.

Show in it:

• 1 - 2C Device according to the invention described herein;
• 3A - 3E another embodiment of the device described here.

In the figures, identical or identically acting components are each provided with the same reference numerals. In the 1 is a device according to the invention 100 shown, the device 100 is set up and provided to detect a usage object in physical terms, in particular optically.

As from the 1 is apparent, includes the device 100 a processing unit 2 , by means of which a usage object 1 and / or a usage object 1 uniquely and preferably uniquely assigned, the identification means 11 is physically detectable, from which at least one characteristic value of the usage object can be obtained and further wherein the processing unit 2 and / or a CPU is set up and provided to carry out a usage object classification to the extent that a characteristic value of the usage object is at least one in a database of the processing unit 2 and / or is comparable to a database of an external CPU and the processing unit 2 and / or the CPU and / or the user himself a characteristic value 3 corresponding database object 4th and in a screen of the processing unit 2 represents, so that a camera image of the usage object 1 together with the database object 4th at least partially visually on the screen 21st can be superimposed and / or displayed next to one another.

By means of the processing unit 2 and / or the CPU is more able to do at least one physical acquisition process 5 based on the in the screen 21st depicted database object 4th perform so that the user can use the object 1 detects that an image of the usage object detected by the detection process is identical or scaled to be identical, at least essentially identical, to that on the screen 21st database object shown 4th is displayed at the same time, whereby the usage object 1 from the processing unit 2 and / or at least one usage object class, for example a vehicle type, can be assigned to the CPU and / or user.

In the 2A an exemplary first step is shown, with the usage object shown there 1 , which is shown in the form of a smartphone, on the screen 21st a usage object class (for example the images 30th ), especially in the form of an example vehicle type, is shown optically. The example vehicle type is not just in the area on a reduced scale B1 presented on the screen but also in a enlarged, for example a 1: 1 shape shaded gray on the screen 21st (see area B2 ) shown.

This optically depicted usage object class, that is to say this depicted vehicle type, serves as an orientation for the object to be photographed. A controller is also shown 40 , by setting a contrast and / or a brightness of the orientation image, that is to say in particular of the images 30th which each correspond to an optical representation of a usage object class. In this way, problems that arise with high brightness can be eliminated.

The 2 B shows characteristic values based on a usage badge 50 of the utility vehicle. Here the usage badge 50 optically through the processing unit 2 scanned. Depending on the usage object to be photographed 1 changes the angle at which the processing unit 2 , shown here as a smartphone as an example, must be held, whereby an optimal quality for the comparison and classification process can be achieved.

In the 2C is shown in a further representation that the processing unit 2 in different angular positions relative to the usage object 1 must be kept.

The above therefore does not just represent the physical sensing process 5 but also the above-described characteristic value acquisition for classifying objects of use.

In the 3 is shown in a further embodiment that the processing unit 2 on a receiving element 23 , in this case a drone, is attached.

The 3A therefore not just a drone 23 , but also in turn the processing unit 2 and the object of use 1 dar, being a drone 23 in the case of a drone launch, initially a distance into the processing unit 2 is entered beforehand or is specified by the acquisition sequence.

Before the drone can orient itself automatically and without a drone pilot, it needs information about the object in use 1 . The drone can then be in front of the vehicle at a defined distance 11 be laid (see 3B) to use the vehicle dimensions in relation to the starting point to fly all positions in accordance with the acquisition sequence. In the 3C are corresponding marking elements 60 shown which either on the usage object 1 are attached or are optically "superimposed" virtually.

The marking can be so-called ARUCo marking. These can be high-contrast symbols that have been specially developed for camera applications. These can not only contain orientation aids, but also information. With such a marker the drone can 23 recognize the starting point of the drone flight yourself.

In the 3D Another sequence of the drone flight is shown, which is also from the 3E emerges. In the 3E however, it is also shown optically, such as the focal length of a lens from the drone 23 transported processing unit 2 affects the recording quality. On the usage object shown on the far left 1 this was recorded with a wide-angle camera, while the usage object shown in the middle 1 with a normal angle camera and the usage object 1 on the far right was taken with a telecamera. The wide-angle camera can be at a distance of 0 to 45 mm from the utility vehicle 2 allow the normal angle camera a distance of about 50 mm and a telephoto lens can allow a distance of 55 mm or more.

This is because focal lengths of less than 50 mm and greater than 50 mm can produce different distortion and distortion effects. Due to the various use of focal lengths of 6 mm, for example, visible distortions occur in the recorded images, so that a comparison of all images can be made afterwards if the recorded photographs should not be post-processed, so that the various lenses mentioned above have to be used.

The invention is not limited on the basis of the description and the exemplary embodiments; rather, the invention encompasses every new feature and every combination of features, which in particular includes every combination of the claims, even if this feature or this combination itself is not explicitly stated in the claims or the embodiments is reproduced.
