Description

Description: The present invention relates to a carrier module for releasably connecting to a receiving cabin having the features of the preamble of claim 1 and to a receiving cabin having at least one such carrier module.

From WO 2006/074310 A2, for example, a digitizing system is known with which a scene can be detected using a texture image and a measurement image and from it a three-dimensional surface model can be generated. The measurement image is thereby generated by projecting an infrared stripe pattern onto a three-dimensional object and simultaneously acquiring a stereoscopic image of the three-dimensional object with the projected pattern, wherein the stereoscopic image is detected by a pair of cameras with upstream infrared photographic filters. The texture image can be captured simultaneously with the measurement image and can be captured by a single texture camera with unfiltered light.

Furthermore, from DE 20 2014 010 159 U1 a visualization studio for generating three-dimensional images with a support frame constructed from a plurality of wall module elements with a plurality of camera units arranged on the wall module elements and a processor-controlled evaluation unit is known. The wall module elements are composable to form a sphere and again detachable from each other. Stereoscopic images are recorded by the camera units which can be actuated at the same time, in each case via adapter elements on the wall module elements, by means of which three-dimensional images can be created by a processor-controlled evaluation device.

A disadvantage of the arrangements known in the prior art or modules or arrangements of image acquisition units, which are suitable for generating three-dimensional images of persons or objects, is the resulting in their construction and construction high workload and due, for example, large dimensions the modules and the high susceptibility to transport damage given poor transportability of such arrangements or modules. Also, the design and setting may require trained specialized personnel. Due to the design, settings made during construction can easily change during transport, which can negatively influence the generation of the images and result in increased maintenance requirements.

The object of the invention is to provide a carrier module in which the aforementioned disadvantages do not occur.

This object is achieved by a carrier module with the features of claim 1 and a receiving cabin with at least one such carrier module. Advantageous embodiments of the invention are defined in the dependent claims.

The object is achieved in that a front surface of the carrier module in the assembled state forms part of a surface surrounded by this interior, and that on the carrier module at least one camera and / or at least a projector for capturing image data of the person to be imaged or of the object to be imaged is or are. As a result, it is possible on the carrier module to create an arrangement of at least one camera and / or at least one projector which, individually or in combination of a plurality of carrier modules, serves to capture image data of a person to be imaged or an object to be imaged. As a camera is generally understood a device for image capture, which creates a two-dimensional image of a person or an object, and may be formed for example as a CCD camera with digitally readable image data. A projector can generally be understood to mean a lighting device or a part of a lighting device for generating light which can be projected onto the person or object to be imaged. The persons or objects to be imaged may have a texture and a volume which are respectively calculated from the image data captured by the at least one camera, possibly also using the at least one projector. A thus calculated three-dimensional volume model of, for example, substantially the entire person or object to be imaged can be coated with the calculated texture to generate a three-dimensional image. The carrier module can be designed to be portable and allow a structurally simple arrangement of the at least one camera and / or the at least one projector. The arrangement of the at least one camera and / or the at least one projector can take place at predetermined positions of the carrier module. The manner of the arrangement on the carrier module can be detachably fastened, for example via a screw connection, or also permanently, for example via a riveted or glued connection.

It can be advantageous that the front surface of the carrier module in a vertical section along a longitudinal extent substantially has a concave curvature. It can thereby be achieved that an arrangement of the at least one camera and / or at least one projector in a curved plane, especially in a plane concavely curved about a horizontal axis, is created by the carrier module about the person to be imaged or the object to be imaged. This allows the covering or positioning of the at least one camera over a large solid angle range of the person to be imaged or of the object to be imaged. The vertical section can be located, for example, by a substantially vertical plane, which runs through the center of the interior of the receiving cabin.

Advantageously, it may be further that the substantially curved front surface is formed by juxtaposed planar partial surfaces. The flat partial surfaces can be strung together at impact, so bordering each other, at a certain angle to each other. In other words, the essentially curved front surface may consist of a traverse following a curve. The flat partial surfaces may have different dimensions and be lined up to form different bending angles to each other.

It can also be provided that the curvature is substantially constant. Such a curved front surface may correspond in its curvature substantially a segment of a circular line.

It can be provided that the carrier module has at least one substantially perpendicular to the front surface adjacent side surface, wherein the side surface adjoins the interior side facing away from the front surface of the front surface and is formed by the front surface and the side surface an inner region of the carrier module , In other words, the carrier module can thus have a substantially L-shaped or also U-shaped cross-section in a horizontal section. A substantially rectangular or C-shaped cross section in such a horizontal section should not be excluded. The inner region of the carrier module can thus be delimited on at least two sides by a surface of the carrier module.

It can be provided that at least one camera and / or at least one projector is arranged in the interior of the carrier module or are. As a result, it may thus follow that the at least one camera and / or the at least one projector is or are arranged on a side of the front surface of the carrier module facing away from the interior of the receiving cabin. The interior of the receiving cabin can thus be kept free of visually disturbing in their appearance elements. The arrangement of the at least one camera and / or the at least one projector in the inner region of the carrier module also provides protection against external influences. This can ensure that the carrier module is easy and safe to transport.

It may be advantageous further that the carrier module is designed as a push-in element. A support module designed as a slide-in element can be moved or pushed into a suitable receptacle, for example a support construct, by a simple, optionally rectilinear motion and thus be connected to the receptacle cabin in a simple and accurate manner, in particular also in a holistic manner.

It may be advantageous that the at least one camera is designed as a camera for capturing image data in the visual area. By a camera, which is designed to capture image data in the visual, visible (optical) region of the light spectrum, for example, the texture of the persons or objects to be imaged can be detected.

Advantageously, it may be further that the at least one camera is designed as a camera for capturing image data in the infrared range. By means of a camera which is designed to acquire image data in the infrared region of the light spectrum which is thus not visible to the human eye, an additional infrared light projected onto the persons or objects to be imaged can be detected, for example. The at least one camera for capturing image data in the infrared region can be used to capture image data for calculating a three-dimensional volume model of the persons or objects to be imaged.

Advantageously, it can be further that the at least one projector for the projection of light is formed on the person to be imaged or the object to be imaged. When capturing image data of the at least one camera, the projector can project light onto the person to be imaged or the object to be imaged.

It may be advantageous that the projected light is infrared light. As a result, image data of the person to be imaged or the object to be imaged can be detected by at least one camera when the light or the same is illuminated with light in the infrared range.

It may be further advantageous that the projector projects a dot pattern, preferably a pseudo-random dot pattern, on the person to be imaged or the object to be imaged. In this case, at least by a camera for capturing image data in the infrared region, image data can be acquired when the person to be imaged or the object to be imaged is illuminated with a pseudo-random dot pattern in the infrared region. By means of such a dot pattern, in which each point within the pattern can have a unique distribution of the distances to its nearest neighbor, it is particularly easy to identify identical regions of the person or object to be imaged in images or image data captured by different cameras. In addition, different projectors of a carrier module or even of several carrier modules can project a pattern which differs in each case from the patterns of the other projectors. As a result, it can be achieved that each point on the surface of the person to be imaged or of the object to be imaged can be clearly distinguished from the other points on the surface, since the projected dot patterns do not repeat.

Advantageously, it may further be that the carrier module has at least one illumination element for illuminating the person to be imaged or the object to be imaged. This can be designed to evenly illuminate the person to be imaged or the object to be imaged. The light conditions in the interior of the receiving cabin can also be controlled or influenced by at least one such lighting element.

It may be advantageous that the illumination element radiates substantially only light in the visual field. As a result, influences of the at least one lighting element on the projection of light in the infrared range can be avoided by a projector.

Advantageously, it may be further that the arranged on the carrier module at least one camera and / or the at least one projector is substantially flat on the front surface of the carrier module, preferably substantially flat and mounted on the side facing away from the interior of the front surface of the carrier module , This can be achieved that the camera or the projector already receives the correct orientation through the assembly and no further adjustment work is needed. The planar assembly can be done in each case plan on a flat portion of the substantially curved front surface of the support module. In general, the assembly can take place in such a way that the optical axis of the camera or of the projector is directed in the direction of the radius of curvature of the curvature of the front surface, ie in the mounting position in the direction of the interior of the receiving cabin. An assembly of the at least one camera and / or the at least one projector on the side facing away from the interior of the receiving cabin side of the front surface of the carrier module may have the advantage that the interior of the receiving cabin itself is kept free of disturbing elements and can also be a relief in the design and For example, bring wiring of the carrier module.

It may be advantageous that the carrier module has at least one information processing device for controlling the at least one camera and / or the at least one projector. By means of such an information processing device, the at least one camera can be actuated to record an image and the projector can be activated for the projection of light. It is also conceivable that each camera or each projector has its own information processing device or even multiple cameras or multiple projectors - even distributed over a plurality of carrier modules - are controlled by an information processing device. The information processing device can also be used to evaluate image data captured by the at least one camera. The information processing device may communicate with the at least one camera and / or the at least one projector via a data link, which may be in the form of a wired connection and may use various interfaces or communication standards, such as USB, Ethernet or I2C. Likewise, a wireless data connection is conceivable, which can be done for example via WLAN or Bluetooth. The information processing device can also communicate with another arithmetic unit via a data connection, wherein the further arithmetic unit can also be used for processing image data.

It may be advantageous that at least one camera and / or the at least one projector at the same time for capturing the image data and for the projection of light can be activated by the at least one information processing device or are. This allows simultaneous acquisition of the image data by the cameras and a projection of light. With a corresponding design of a carrier module or a plurality of carrier modules, a simultaneous recording of the image data of the cameras in the visible range for detecting the texture and the image data of the cameras in the infrared range for detecting the volume can be made possible. By such a control, the recording of the image data for calculating the texture of the body without time difference for receiving the image data for the calculation of the three-dimensional volume model is possible.

It may also be provided that a portion of the cameras for capturing image data in the visual field as wide-angle cameras, so cameras with particularly large angle range detected by these, are formed and this circumferentially at the same height - for example, approximately at hip height to be imaged Person - are arranged. With a group of cameras arranged in this way, a preview of the detected texture can be generated quickly and without much computational effort. Such an arrangement is also known as "inverse panorama".

As mentioned above, protection for a receiving cabin is desired with at least one carrier module. By arranging a plurality of side by side - for example, along a peripheral line around the person to be imaged or the object to be imaged - arranged carrier modules, a spatial arrangement of cameras and / or projectors along substantially horizontally extending circumferential lines, for example, along substantially horizontally extending latitudinal circles, and along of substantially vertically extending circumferential lines, for example along substantially vertically extending sections of longitudinal circles. As a result, it is also possible to achieve a spatial arrangement of cameras and / or projectors at regular or even intervals around the person to be imaged or the object to be imaged, by means of which seamless recording of their texture and / or volume can be made possible. Due to the regularity of the arrangement or also by the placement and number of the carrier modules for calculating the texture and the volume, the required overlap between the respectively acquired image data can be optimized. Also, an arrangement of cameras and / or projectors can be achieved by appropriate placement and distribution of the carrier modules, in which cameras of a particular group, for example a group of cameras for capturing image data in the visible range of the light spectrum, in their effectively resulting arrangement order wind the person to be imaged or the object to be imaged upwards or downwards helically or spirally. By such an arrangement, the smallest possible number of cameras and / or projectors can result, which can cover the largest possible area on the object to be measured.

In such a receiving cabin may be advantageous that the carrier module is arranged substantially vertically in mounting position along its longitudinal extent. Such an arrangement makes it possible to cover image areas or illumination areas in a substantially vertical direction by the at least one camera and / or the at least one projector of the carrier module. Thus, an arrangement of cameras and / or projectors along a substantially vertically extending circumferential line, for example along a substantially vertically extending section of a circle of longitude, can be created by a single carrier module.

Further, it may be advantageous that the receiving cabin has a support structure and the at least one support module from an inner region of the receiving cabin radially outwardly into the support structure can be inserted and preferably in the support structure is detachably fastened. Such a support structure may have shaft-shaped receptacles for one or more support modules, in which a support module can be inserted for mounting and it can also be releasably secured therein. To align and adjust the cameras and / or the projectors no further steps are necessary.

Further, it may be advantageous that the receiving cabin has one of a - preferably curved - surface formed interior, a ceiling and a floor, and wherein in the floor and / or the ceiling in addition at least one camera and / or at least one projector for detecting of image data of the person to be imaged or the object to be imaged is or are arranged. This allows the widest possible area of the interior of the receiving cabin to be used for generating a three-dimensional image of a person or an object. This can be achieved by using as few cameras and projectors as possible.

Also, it may be advantageous if the carrier module and the support structure having mutually corresponding connection devices, preferably connectors, for data line and / or power supply for the at least one camera and / or the at least one projector of the at least one carrier module, wherein it is at an insertion the carrier module in the supporting structure for forming a connection of the connecting devices comes. A connection to the at least one information processing device may also be provided. Thus, a connection of the carrier modules to a supply network or a data network of the receiving cabin can be carried out when mounting the carrier modules in the receiving cabin. As a result, it is possible to reduce the amount of work and time required to build up the receiving cabin.

Further, it may be advantageous that a first group of cameras for capturing image data in the visual area, a second group of cameras capturing of image data in the infrared range and a lighting device with at least one projector for the projection of by the at least one carrier module in mounting position Infrared light, preferably a dot pattern of infrared light, is formed. The carrier modules may further comprise at least one information processing device, by which the cameras of the first group, the cameras of the second group and the projectors are controllable and to which the image data of the cameras of the first and the second group can be supplied, wherein from the image data of the cameras of the first Group the texture of at least a part of the person to be imaged or the objects to be imaged can be calculated.

Also, ultimately, a - preferably integrated in the information processing device - computing unit may be provided which calculates a three-dimensional volume model of the entire body of the image data of the cameras of the second group - and possibly the image data of the cameras of the first group.

One of a single, along its longitudinal extension substantially vertically arranged support module 1 created arrangement would thereby an array of cameras 41, 42 and projectors 5 along the substantially vertical circumferential line 19 (here only shown as a section) correspond. In this case, the carrier modules 1 can be equipped and arranged such that, for example, for the cameras 41 for capturing image data in the visual range, a helical spatial distribution indicated by the dashed line 20 results.
