Description

Technical Field

[0001] The present invention relates to a reality capture device for generating a digital three-dimensional representation of an environment, in particular for surveying or monitoring infrastructure. Background Art

[0002] Reality capture devices often utilize a variety of sensors. For example, a combination of different cameras, such as visual and thermal cameras, can be used to provide both daytime and nighttime surveying and monitoring capabilities. Different sensors also provide different information, enabling improved object recognition and detection of critical events, such as based on visual appearance and temperature.

[0003] LiDAR (Light Detection and Ranging) technology can be used to create light barriers for intrusion detection or mobile sensors for movement detection.

[0004] Laser scanning units can be used to generate 3D point clouds of infrastructure for surveying or monitoring infrastructure and objects within it in three dimensions. In the case of monitoring, for example, this enables 3D change detection and 3D object tracking in any light conditions.

[0005] As an example, reality capture devices are used to monitor nerve pain points in cities, such as train stations, airports, city parks, or other busy public places. Reality capture devices are also used to monitor or protect restricted or dangerous areas, such as factories, construction sites, or commercial buildings.

[0006] Nowadays, increasingly standardized reality capture devices are used in modern survey systems. These devices are capable of autonomously identifying objects and / or situations related to a scene to be monitored, for example, to automatically issue an alarm or to mark a scene for review by a human operator. For example, a distributed network of reality capture devices is used, configured to automatically identify and track people or other mobile objects, such as cars, so that the path of the mobile object can be automatically followed using data from the network of reality capture devices.

[0007] As another example, reality capture devices are used to support the operation of a facility, such as supervision of a warehouse or parking lot.

[0008] In the field of surveying, reality capture devices are beneficial for architects or craftsmen to quickly assess the actual condition of a room or the progress of a construction site, for example, to effectively plan the next work step. Using a digital visualization of the actual condition, for example in the form of a point cloud or vector file model, or using augmented reality functions, different options for further steps or expansions can be examined and optionally presented to employees or clients in an easily accessible manner.

[0009] There is now increasing standardization of referencing and fusing of different data types, such as laser scanner data, camera data, and positioning data such as from global navigation satellite systems.

[0010] In particular, the reality capture device can be mobile and configured to provide survey data and reference data simultaneously, for example, wherein at least trajectory data (e.g., position and / or pose data) of the device is provided together with detection data (e.g., laser scanner data and / or camera data), so that detection data from different positions of the reality capture device can be combined into a common coordinate system. Typically, the reality capture device is configured to autonomously create a 3D map of the new environment, for example, by means of a simultaneous localization and mapping (SLAM) function.

[0011] The 3D model data can then be analyzed using feature recognition algorithms to automatically identify semantic and / or geometric features captured by the probe data, for example, by using shape information provided by the virtual object data from the CAD model. This type of feature recognition, particularly for identifying geometric primitives, is now widely used to analyze 3D data.

[0012] For example, the trend toward increasing the functionality of modern reality capture devices has led to an increasing demand for compact integration of complex sensor technologies accompanied by miniaturization of electronics and optics. At the same time, the lifespan of reality capture devices must be maintained or increased.

[0013] While the development of miniaturized electronics and optical components has enabled the miniaturization and compact design of reality capture devices, heat generation within the devices remains a problem, and the cooling effort for key components has remained essentially the same or even increased. For example, the lifespan and handling of reality capture devices are closely tied to temperature control. Summary of the Invention

[0014] It is an object of the present invention to provide an improved reality capture device that is more compact and easier to use.

[0015] Another object of the present invention is to provide a more compact reality capture device while increasing the robustness and longevity of the device.

[0016] These objects are achieved at least in part by the following means.

[0017] The present invention relates to a reality capture device for generating a digital representation of an environment, the reality capture device comprising a laser scanner and a housing enclosing an interior space, the interior space including at least a portion of the laser scanner. The laser scanner is configured to provide a scanning movement of a laser measurement beam for generating lidar data, which can be used, for example, to generate a three-dimensional model such as a three-dimensional point cloud or a three-dimensional mesh.

[0018] The reality capture device is configured such that the interior space has a first climate zone and a second climate zone. For example, the second climate zone provides a cooling capacity (for cooling components arranged within the second climate zone) that is different from the cooling capacity of the first climate zone (for cooling components arranged within the first climate zone). Thus, the use of two different climate zones advantageously enables grouping different heat sources with different cooling requirements, which provides optimized cooling for the reality capture device, particularly a compact reality capture device.

[0019] As another example, during operation of the reality capture device, the second climate zone provides a nominal temperature range that is different than the nominal temperature range of the first climate zone.

[0020] For example, the two climate zones can be thermally isolated from one another by an insulating layer and / or by being constructed and arranged relative to one another in such a way that air circulation between the two zones is prevented.

[0021] Each of the climate zones is connected to a corresponding heat sink element, and each heat sink element is configured to transfer heat from an internal component of the heat sink element arranged inside the corresponding climate zone to an external component of the heat sink element arranged outside the corresponding climate zone.

[0022] The heat dissipation element can be configured to passively transfer heat, for example, wherein the heat dissipation element comprises a heat pipe that is in thermal contact with the corresponding climate zone and connected to external cooling ribs. The heat dissipation element can also be configured to actively pump heat from one end to the other, for example based on the Peltier effect, and thus actively generate a temperature gradient from one end to the other.

[0023] According to one aspect of the invention, the reality capture device has a common air circulation element, such as a common fan, which is configured to provide active air circulation through the air guiding device for cooling the external parts of the heat dissipation element, wherein the air guiding device is configured such that different air flow characteristics of the active air circulation are achieved with respect to different areas associated with the cooling of the external parts of the heat dissipation element (the areas associated with the cooling of the external parts of the heat dissipation element connected to the first climate zone are different from the areas associated with the cooling of the external parts of the heat dissipation element connected to the second climate zone).

[0024] According to another aspect of the invention, separately or in combination with the above aspect, the first climate zone is configured without active air circulation and the second climate zone is configured with active air circulation for guiding air to the inner parts of the corresponding heat dissipating elements.

[0025] As an example, two different climate zones are connected by heat conduction to two different areas of the air guiding device, wherein outer parts of the heat dissipating element are configured as cooling ribs or cooling fins (or the like) exposed to the air flow generated by the common air circulation element.

[0026] In order to generate different air flow characteristics in different areas, the air guiding device comprises, for example, air ducts of different shapes and / or sizes, for example, wherein the cross-section of the air ducts is different for different areas.

[0027] In particular, the air ducts of the air guiding device can be formed / defined by specifically arranging and shaping cooling elements such as cooling ribs or cooling fins to provide different air flow characteristics. Alternatively, different air flow characteristics can be generated by the air guiding device independently of the arrangement and shape of the cooling elements.

[0028] In one embodiment, the air guiding device comprises a plurality of sections which are insulated from one another against heat conduction from one section to the other sections, in particular wherein the second climate zone is connected by heat conduction to a section of the air guiding device which is insulated from the rest of the air guiding device against heat conduction.

[0029] In another embodiment, the air guiding device extends on the side surface of the reality capturing device at least along a portion of a circumference around the vertical axis of the reality capturing device. In particular, the air guiding device extends along the entire circumference around the vertical axis.

[0030] In another embodiment, the air guiding device includes cooling ribs associated with cooling the outer portion of the heat dissipation element, wherein the cooling ribs have varying spacing relative to one another. For example, the cooling ribs are arranged on a side surface of the reality capture device along at least a portion of a circumference about the vertical axis, and the spacing between the cooling ribs varies along the circumference.

[0031] For example, the distance between the cooling ribs which are designed to cool the second climate zone is smaller than the distance between the cooling ribs which are designed to cool the first climate zone.

[0032] In another embodiment, the first climate zone includes at least a part of the electronic components of the laser scanner, in particular a computing unit for controlling the laser scanner and / or for data processing, such as for processing lidar data or laser scanner data including lidar data of scanning movements of the laser measuring beam and angle data.

[0033] In another embodiment, the laser scanner has a static section that is included in the first climate zone and that is free of rotating parts of the laser scanner.

[0034] In another embodiment, the second climate zone comprises at least one of: a radiation source for generating a laser measurement beam, an optical component configured to interact with the laser measurement beam (e.g. a deflection element such as a rotating mirror), and a detector for receiving at least a portion of the laser measurement beam.

[0035] In another embodiment, the laser scanner has a movement section which is comprised in the second climate zone and which comprises a rotation part for providing a scanning movement of the laser measuring beam.

[0036] In another embodiment, the second climate zone is sealed against external penetration to at least IP67.

[0037] In another embodiment, the heat-dissipating element of the second climate zone is configured to actively generate a heat transfer from an inner part to an outer part of the heat-dissipating element, for example based on the Peltier effect.

[0038] In another embodiment, the reality capture device includes insulation that isolates the second climate zone from the rest of the reality capture device to resist thermal conduction. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] Figure 5 An embodiment of an exemplary structure of an air guiding device is schematically depicted, which has two sections that are insulated from one another against heat conduction. DETAILED DESCRIPTION

[0045] Figure 1 An exemplary application of a reality capture device 1 in the field of surveillance, for example for monitoring a crowded subway station, is shown. Typically, such a monitoring system comprises multiple reality capture devices 1 distributed throughout the infrastructure to provide complete coverage with minimal blind spots. For example, modern monitoring systems utilizing reality capture devices within the meaning of the present invention are configured to automatically identify and track pedestrians 2 based on data from the reality capture devices, and to automatically detect left behind objects 3, such as suitcases, that could potentially contain hazardous materials or explosives.

[0046] Typically, reality capture devices 1 utilize a variety of sensors, such as for visual and infrared imaging, range imaging, or 3D scanning. Particularly for monitoring purposes, the devices must be compact, lightweight, and quiet, while also being robust against damage and manipulation. Because some of the sensors and electronics used generate significant heat, these requirements quickly conflict with typical cooling solutions, which, for example, would prefer large (and loud) fans, bulky components, and an open device architecture.

[0047] In particular, the use of laser scanning units generates significant amounts of internal heat that must be transported away from critical device components.

[0048] Figure 2 An exemplary embodiment of the basic structure of a reality capture device according to the invention is shown, here comprising a laser scanner 4 and an imaging camera 5. By way of example, the laser scanner 4 is implemented as a 3D laser scanner, which provides a scanning movement of a laser measuring beam 6 relative to two different, here two essentially orthogonal, axes of rotation 7, 8.

[0049] The laser scanner 4 comprises a base 9 and a support 10 which is rotatably mounted on the base 9 about a support rotation axis 7, said support typically defining an upright axis 11 of the laser scanner or the reality capture device, respectively. Rotation of the support 10 about the support rotation axis 7 is also referred to as azimuthal rotation, regardless of whether the laser scanner or the support rotation axis 7 is exactly aligned vertically.

[0050] The laser scanner 4 further comprises an optical distance measuring unit 12, which is arranged in the support 10 and is configured to perform distance measurements by emitting transmitted radiation 6 (e.g. pulsed laser radiation) and detecting the returned portion of the transmitted radiation by means of a receiving unit comprising a light-sensitive sensor. Thus, pulse echoes are received from backscattered surface points of the environment, wherein the distance to the surface point can be derived based on the flight time, shape and / or phase of the emitted pulses.

[0051] The scanning movement of the laser measuring beam 6 about the two rotation axes 7 , 8 is performed by rotating the support 10 relative to the base 9 about the support rotation axis 7 and by means of a rotation body 13 rotatably mounted on the support 10 and rotating about the beam rotation axis 8 .

[0052] As an example, both the transmitted radiation 6 and the returned portion of the transmitted radiation are deflected by means of a reflecting surface which is integral with the rotating body 13 or are applied to the rotating body 13 .

[0053] Alternatively, the transmitted radiation may come from the side facing away from the reflective surface, ie from the interior of the rotating body 13 , and be emitted to the environment via a channel region in the reflective surface, for example by using a prism mounted inside the rotating body 13 .

[0054] In order to determine the emission direction of the distance-measuring beam 6, a number of different angle determination units are known in the prior art. For example, the emission direction can be detected by means of an angle encoder that is configured to acquire angle data for detecting the absolute angular position and / or relative angular change of the support 10 about the support rotation axis 7 or the absolute angular position and / or relative angular change of the rotating body 13 about the beam rotation axis 8, respectively. Another possibility is to determine the angular position of the support 10 or the rotating body, respectively, by detecting only complete rotations and using knowledge of a set rotation frequency.

[0055] Visualization of the data and, for example, fusion with camera data can be generated by using known data processing steps and / or display options, for example wherein the acquired data are presented in the form of a 3D point cloud or wherein a 3D vector file model is generated.

[0056] Figure 3 The interior of a reality capture device according to the present invention is schematically depicted, said interior having a first climate zone 14 and a second climate zone 15. Heat from the two climate zones 14, 15 is transferred to the exterior of the reality capture device by heat conduction via heat dissipation elements (not shown), wherein outer parts 16 of the corresponding heat dissipation elements (e.g. cooling ribs or cooling fins) are exposed to the heat dissipation provided by an air guiding device (e.g. see Figure 4) generated air flow.

[0057] According to one aspect of the invention, the first climate zone 14 is configured without active air circulation, and the second climate zone 15 is configured with active air circulation for directing air to the inner components of the corresponding heat dissipating elements (components within the second climate zone), here, for example, represented by the “cold side” 17 of the Peltier element (see below).

[0058] As an example, the first climate zone 14 includes fewer heat-sensitive components or components that generate less heat than the second climate zone 15. For example, the second climate zone 15 includes heat-sensitive components of a laser scanner, such as a laser source or a lidar detector for generating a laser measurement beam, which have higher requirements for temperature control than other components of the reality capture device, such as the electronics of the laser scanner.

[0059] For example, a laser diode is often one of the key components, where the diode is specified to a maximum temperature of, for example, 70° C. To increase the lifetime of the laser diode, the second climate zone 15 can be temperature-controlled such that during operation of the reality capture device, the temperature of the second climate zone 15 is maintained well below the specified maximum temperature of the laser diode, where, for example, the maximum nominal temperature of the second climate zone is 60° C. As an example, the reality capture device is configured to provide a nominal temperature range of 45° C. to 60° C. within the second climate zone 15 during operation of the reality capture device.

[0060] In particular, the reality capture device is configured to provide a nominal temperature range for the second climate zone 15 during operation of the reality capture device, the nominal temperature range having an upper nominal temperature boundary below 60°C, more particularly below 50°C.

[0061] In contrast, the requirements for the nominal temperature range of the first climate zone 14 may be more relaxed, for example where the first climate zone 14 comprises the electronics of the laser scanner 4. As an example, the electronics for control and / or for data processing may tolerate temperatures of up to 70°C.

[0062] Thus, the nominal temperature range of the first climate zone 14 may be arranged to tolerate average temperatures close to 60°C or even close to 70°C during operation of the reality capture device.

[0063] In the embodiment shown, the second climate zone 15 is cooled using a Peltier element for actively pumping heat from a so-called “cold side” 17 of the Peltier element to a so-called “hot side” 18 of the Peltier element, which is connected to cooling ribs 16 .

[0064] Figure 4Three different views of an exemplary embodiment of a reality capture device according to the present invention are shown, the left and middle illustrations being side views rotated 180 degrees relative to each other, and the right illustration being a top view.

[0065] As an example, the reality capture device comprises a laser scanner 4 and four cameras 5, which are arranged circumferentially around an upright axis 11 on a housing of the reality capture device. Here, the housing comprises a protective cover 19 and completely surrounds the laser scanner 4. For example, the cover 19 is opaque to visible light and semi-transparent to the wavelength range of the transmitted radiation, for example, where the transmitted radiation is emitted in the infrared wavelength range. Thus, rotating parts of the laser scanner, such as Figure 2 As shown, it is concealed by the cover 19, wherein the cover is stationary relative to the base 9 (e.g. Figure 2 ).

[0066] The reality capture device has a cooling device having a fan (not shown) which is configured to provide active air circulation through the air guiding device for discharging heat from the interior of the reality capture device to the surrounding environment, for example, wherein the heat is discharged to cooling ribs or cooling fins which are exposed to the air flow generated by the air guiding device. For example, the cooling ribs are arranged at the air inlet 20, where the cooling ribs are arranged circumferentially around the vertical axis 11 of the reality capture device on the side surface of the reality capture device, wherein the air guiding device provides an air flow of ambient air through the air inlet 20 to the air outlet 21 for discharging the heated air to the surrounding environment. Additional air inlets 22 can be used to increase the cooling capacity, for example for cooling particularly hot components, such as the "hot side" of a Peltier component (see for example Figure 3 ).

[0067] The air guiding device is configured such that different air flow characteristics of the active air circulation are achieved for different zones. For example, the spacing of the cooling ribs varies along the circumference, for example the spacing between the cooling ribs of the first zone 23 associated with the cooling of the first climate zone 14 (see Figure 3 ) is wider than the spacing between the cooling ribs of the second area 24 associated with the cooling of the second climate zone 15 .

[0068] Figure 5 An exemplary embodiment of the structure of an air guiding device is schematically depicted. Here, the air guiding device comprises two sections 25 , 26 , which are insulated from one another by a thermal insulation layer 27 to counteract heat conduction.

[0069] As an example, one of the sections 25 has a narrower air duct than the other section 26 and is thermally connected to the second climate zone 15 (see FIG. 1 ) comprising heat-intensive and / or heat-sensitive components of the laser scanner. Figure 3), wherein the other section 26 is thermally connected to the first climate zone comprising relatively few heat-sensitive components (eg processing electronics). Thus, a thermal short circuit between the two climate zones is suppressed.

[0070] In order to force the air flow through the air duct, the air guiding device can include a cover (not shown). As an example, the cooling ribs can be manufactured in an extrusion process so that the shape and arrangement of the cooling ribs define the air flow characteristics provided by the air guiding device. The cover can be made of plastic.

[0071] Although the present invention has been described above in part with reference to some preferred embodiments, it must be understood that many modifications and combinations of the different features of the embodiments are possible, all of which are within the scope of the appended claims.
