Further subjects of the invention form a simulation system for simulating a vehicle operating device in the interior of a vehicle, in particular a military vehicle, within a simulation room and a method for setting up such a simulation system in the simulation room.
- the invention is used to simulate the interior of a vehicle, in particular a military vehicle, in a simulation room.
- Simulation rooms are used on the one hand to train crew members of the vehicle for initial initial training or to refresh and further memorize processes that have already been trained in operating the vehicle.
- simulation rooms are also used in the conception or further development of the vehicle interior as part of a design process, in particular on the part of the manufacturer.
- the simulation of the vehicle interior that takes place in the simulation room enables the training or the design process to be carried out without having to use a real vehicle.
- the simulation is significantly more flexible and easier to change and adapt than the real vehicle interior.

For example, a collision with the real operating device is possible during a movement, which cannot occur with a pure VR simulation.

Due to the different viewing angles of the 3D sensor systems, obscuring the real operating device can be avoided even more reliably, since the real operating device is at the same time can be recorded by several 3D sensor systems from different angles.
- the position of individual points in the simulation space is measured relative to the 3D sensor system.
- the depth information of the entire simulation space can be recorded in a simple manner.
- To measure the position of a point in particular its distance and its solid angle relative to the 3D sensor system can be determined.
- the position of individual points can advantageously be measured by means of the 3D sensor system in the manner of a time-of-flight camera.
- the points to be measured can be marked points on the real operating element, which are marked, for example, with markers or in color.
- the points can also be specified by a regular or irregular scanning pattern of the 3D sensor system.
- the regular scanning pattern can correspond to the arrangement of the image points of the 3D sensor system.
- the position of each pixel of the depth camera can be determined in the simulation space.
- the specification of the points by a regular or irregular scanning pattern of the 3D sensor system can offer the advantage that other objects can also be detected.
- These other objects can be displayed in the virtual environment in addition to the real operator panel.
- These other objects can be, for example, an obstacle element that simulates the spatial conditions in the real vehicle interior. In this way, the realism of the simulation can be increased.
- the position of the real operating device in particular a large number of individual points on the real operating device, is measured relative to the 3D sensor system.
- the measurement of the position offers a higher precision and accuracy than is possible with a method based purely on the interpretation of image information.
- the position and location of individual operating elements can be precisely recorded.
- the actuation of the real operating device can thus be detected via a change, in particular the position of one of the operating elements of the real operating device, and represented accordingly in the virtual environment.
- the measured positions are preferably combined into point cloud data and displayed as a point cloud in the virtual environment.
- the point cloud data contains the position information of the measured points.
- the individual points of the point cloud data can be stored in a format containing color and position information.
- this format can contain, for example, the distance to this 3D sensor system as well as the color values for red, green and blue or the color values for yellow, magenta, cyan.
- the format can contain the coordinates of the respective point based on a coordinate reference system, especially when using several 3D sensor systems, as well as the color values for red, green and blue or the color values for yellow, magenta, cyan.
- the point cloud data can be passed on in a simple manner to a rendering system generating the virtual environment, in particular the server or the simulation computer, for display.
- a rendering system generating the virtual environment, in particular the server or the simulation computer
- By displaying the point cloud data as a point cloud a more error-tolerant display of the real environment and in particular of the hands in the virtual environment can be achieved than would be possible with a display with a more computationally intensive, closed polygon mesh that includes the point cloud data.
- An error-prone conversion of the point cloud data into a polygon mesh or into a reshaping of a stored closed polygon mesh can be dispensed with.
- the simulation room can be empty; in particular, neither the setter nor another person is in the simulation room during the exposure, nor is the operating device (s) in the simulation room.
- This one-time created background depth recording can be used to subtract the background in the manner of a "background subtraction" process. In this way, points in space are recognized that lie in front of this background depth recording. This makes it easy to identify the fitter, his hands and everything that has changed since the background depth photograph was taken. What lies in front of the background depth recording is determined within a tolerance threshold which is selected to be sufficiently large to reliably filter potentially noisy sensor data. Since the depth information together with the color information form the point cloud data, it is possible to identify the points that change in the simulation space, in particular the points of the operating device. The resulting reduction in point cloud data is particularly advantageous. Only the points that have changed compared to the background depth recording are processed, transferred and displayed.

- 11 shows a calibration of several 3D sensor systems on top of one another.
- the simulation room 200 shows a simulation room 200 with a setter 100 located therein, which sets up the simulation system 1 in it.
- the simulation room 200 is located outside the real vehicle 1000 and can in particular be accommodated in a building of a training center or a design workshop.
- the setter 100 positions in the simulation room 200 at the facility that belongs to the simulation system 1.
- Real operating devices 5 in order to simulate the vehicle interior 1100 and in particular a vehicle operating device 300 at a crew position in the vehicle interior 1100, such as a commander, driver or gunner.
- the setup can be a pure replica Set-up, in which the setter 100 positions the real operating device 5 to simulate a predetermined vehicle interior in the simulation room 200, or a design set-up act, in which the setter 100 as the designer of the simulated vehicle interior as part of a design process associated with the set-up redesigned or redesigned and for this purpose the real operating element 5 is positioned in the simulation room 200.
- the setup person 100 wears a display device 4 which is designed in the manner of VR glasses.
- This display device 4 is fixed to the head and is arranged in the field of vision of the setter 100, so that the setter 100 is shown a purely virtual environment 2 via the display device 4.
- This virtual environment 2 can be a simple, essentially empty space. However, it can also be a visual simulation of the vehicle interior 1100 of a real vehicle 1000. This virtual environment can, for example, be displayed to a crew member of the vehicle 1000 during training with the simulation system 1. In this case, the virtual environment 2 also contains further representations of objects and items that are not actually present in the simulation space 200.
- the fitter 100 can thus find himself, for example, in an armored turret 2.1. Nevertheless, the virtual environment 2 can also only be used for setting up, while the simulation, in particular for training a crew member, can be carried out without a virtual environment 2 and without a display device 4.
- Objects that have no counterpart in the simulation space 200 such as a weapon 2.2, for example, can be represented in the virtual environment 2 of the armored turret 2.1.
- Other objects in the virtual environment 2 have a counterpart in the simulation room 200, such as the virtual operating devices 3, which are assigned to the real operating devices 5.
- the real operating devices 5 arranged in the simulation room 200 provide haptic feedback when the virtual operating device 3 is operated.
- the real operating devices 5 are arranged in the simulation room 200 in such a way that their relative position and location to the display device 4 correspond to the position and location of the virtual operating device 3 to the display device 4 in the virtual environment 2.
- the real operating device 5 should therefore be at the same position in the simulation room 200 as the virtual operating device 3, which is displayed in the virtual environment 2. Since only the virtual environment 2 can be visually perceived via the display device 4, the haptic feedback of the real operating device 5 assigned to the virtual operating device 3 enables this virtual operating device 3 in the perception of the fitter 100 or a crew member during a training simulation to feel.
- two signal transmitters 18, which belong to a VR display system are arranged in the simulation room 200.
- the position and location of the display device 4, which also belongs to the VR display system, and thus also the position and location of the setter 100 in the simulation room 200 can be determined via this signal transmitter 18.
- the stationary signal generators 18 send position signals into the simulation room 200, which signals are received by the display device 4.
- the display device 4 and the signal transmitters 18 are synchronized with one another in such a way that the received time difference between the transmission of the position signals from one of the signal transmitters 18 and the reception of that position signal the distance between the respective signal generators 18 and the display device 4 can be determined by the display device 4.
- a triangulation of the position of the display device 4 in the simulation space 200 is then carried out using the known distances between the stationary signal generators 18 and the display device 4.
- the display device 4 also has sensors (not shown in the figure), in particular position sensors, with which it is also possible to determine the position of the display device 4 in the simulation space 200. In this way, a tilting or tilting of the display device 4, which corresponds to a corresponding tilting or tilting of the head of the fitter 100, can be detected and taken into account when the virtual environment 2 is displayed on the display device 4.
- the setter 100 Since the setter 100 only sees the virtual environment 2 and not the interior of the real simulation room 200 via the display device 4, the setter 100 cannot directly perceive the position and location of his own hands visually either.
- a plurality of sensors for recognizing the hands of the fitter 100 are arranged in the simulation room 200.
- the sensors are 3D sensor systems 7, which are designed in particular as 3D camera systems. These 3-D sensor systems 7 also serve to detect the real operating device 5 in the simulation room 200.
- the coordinate system of the 3-D sensor system 7 and a coordinate system of the VR display system of the simulation system 1, which includes the display device 4, are calibrated to one another.
- a spatial point P in the simulation space 200 is recognized as being in the same position after the calibration by the 3D sensor system 7 and the VR display system. Positions in the virtual environment 2, which is displayed via the display device 4 in the coordinate system of the VR display system, are based on these Congruently with corresponding positions in the real simulation space 200.
- the action area 201 of the fitter 100 in the simulation room 200 is monitored with the 3-D sensor system 7.
- the action area 201 is the area of the simulation room 200 in which the hands of the setter 100, the crew member to be trained or a designer can move during the simulation in a set up simulation system 1 to operate the real operating device 5.
- one of the 3-D sensor systems 7 is arranged in the rear area of the simulation room 200 and offset upwards in relation to the action area 201 in the simulation room 200.
- This 3D sensor system 7 casts an over-the-shoulder view of the action area 201, so that, if possible, the real one is covered or shaded
- Control device 5 in the action area 201 can be avoided. Even if the fitter 100 extends his hands far into the action area 201 to position the real operating device 5, this over-the-shoulder view enables a largely undisturbed detection of the real operating device 5 within the limits of the sensor area 7.1 without the real operating device being affected. advises 5, for example by the hands or arms of the fitter 100, is covered.
- the setter 100 can move largely freely in the simulation room 200, despite this over-the-shoulder view, it cannot be ruled out that the real operating device 5 may be covered up if, for example, the setter 100 is different from the one in FIG Fig. 1 assumes the position shown.
- another 3-D sensor system 7 is arranged in the simulation room 200. This is arranged below the real operating device 5 and offset to the side by the setter 100, so that it is inclined from Looks at action area 201 below.
- Such an arrangement of the 3D sensor systems 7 has the advantage that even if the real operating device 5 in the action area 201 is covered or shaded from the point of view of one of the 3D sensor systems 7, the position of the real operating device 5 is nonetheless caused by the other 3D sensor system 7 can be detected.
- 3D sensor systems 7 can also be arranged in the simulation room 200, whereby the probability of the real operating device 5 being hidden from all 3D sensor systems 7 can be further reduced and the reliability of the detection of the position and location of the real operating device 5 is further increased.
- obstacle elements 19 that can be positioned are also arranged in the simulation room 200. For the sake of clarity, only one obstacle element 19 is shown in FIG. 1, it also being possible for further elements to be arranged in the simulation room 200. With this obstacle element 19, the spatial restrictions of the vehicle interior 1100 of the real vehicle 1000 can be reproduced.
- these spatial restrictions correspond to the spatial conditions as they exist in the virtual environment 2 and are presented to the setter 100 via the display device 4. If the fitter 100 moves within the simulation room 2 in such a way that this would lead to a collision with other elements in the vehicle interior or the vehicle wall, then the obstacle element 19 provides appropriate feedback to the fitter 100.
- an impact on the obstacle element 19, which is at the same position relative to the fitter 100 in the simulation room 200 becomes like a corresponding virtual obstacle 2.3 in the virtual environment 2 or a corresponding obstacle 1003 in the real vehicle 1000 is realistically prevented from penetrating such a virtual obstacle.
- These obstacle elements 19 can be positioned in the simulation room 200 during setup in the same way as is described below for the real operating devices 5.
- the combination of display device 4, real operating element 5, 3D sensor systems 7 and signal transmitter 18 forms a structurally simple simulation system 1.
- the simulation system 1 can be set up in different simulation rooms 200. In this way, for example, a room otherwise used as an office can be converted into a simulation room 200.
- the individual components of the simulation system 1 can be set up differently in the simulation room 200 depending on the vehicle type to be simulated, and the simulation room 200 can in this way be flexibly adapted to a simulation to be carried out.
- the simulation system 1 also includes further elements that are not used in the simulation shown, such as further real operating devices 5 or obstacle elements 19, which have a different shape than the obstacle element 19 shown in FIG. 1.

- toggle switch make can be used for the toggle switches 5.1a can be used than is the case with the toggle switch 301a of the vehicle operating device 300.

- each of the partial cameras 8.1 simultaneously records an independent image of the real operating device 5. Since the real operating device 5 in the simulation room 200 is seen by the two partial cameras 8.1 each at a different solid angle ⁇ , ⁇ relative to their respective straight-ahead direction R and the distance between the two partial cameras 8.1 is known from one another, the distance A of individual points can be the real operating device 5 and thus also the entire real operating device 5 can be determined by triangulation.

- the 3D sensor system 7 shown in FIG. 10b has a depth camera 8 in the manner of a time-of-flight camera with a transmission module 8.2 and a reception module 8.3.
- the distance A between the real operating device 5 and the 3D sensor system 7 is not determined via triangulation with multiple recordings, but rather via the transit time of a light pulse 10.
- the transmitter module 8.2 emits this light pulse 10, which is thrown back by the real operating device 5 as a reflected pulse 11 and hits a light sensor 8.4 of the receiving module 8.3.
- the light pulse 10 emitted by the transmission module 8.2 can be emitted as a wide-spread pulse, which in particular can cover the area lying between the limits of the sensor area 7.1.
- the light pulse 10 can be a focused pulse, which the transmission module 8.2 emits in a time offset along a different spatial direction for scanning the area extending between the boundaries of the sensor area 7.1.
- the transmitting module 8.2 and the receiving module 8.3 are synchronized with one another in such a way that the time between the Emitting the light pulse 10 by the transmitter module 8.2 and the detection of the reflected pulse 11 by the light sensor 8.4 of the receiving module 8.3 can be precisely determined.
- the distance A can be determined from this time difference and the known propagation speed of the light pulse 10 and the reflected pulse 11.

- the simulation room 200 is shown with two 3D sensor systems 7 arranged therein.
- Each of the 3D sensor systems 7 has its own coordinate system B1, B2 in which the position of a point in space P measured by the respective 3D sensor system 7 is determined.
- a coordinate reference system B0 to which the 3-D sensor systems 7 are to be calibrated, is also shown in the simulation space 200.
- This coordinate reference system B0 can be a coordinate system of a third 3D sensor system 7 or, for example, a coordinate system assigned to the display device 4.
- An individual spatial point P located in the simulation space 200 is assigned its own different coordinates in each of the coordinate systems B1, B2 and the coordinate reference system B0.
- the spatial point P in the coordinate system B1 bears the Cartesian coordinates x 1 , y 1 and z 1 , in the coordinate system B2 the Cartesian coordinates X 2 , y 2 and Z 2 and in the coordinate reference system B0 the Cartesian coordinates x 0 , y 0 , z 0 . So that this individual spatial point P is assigned the same coordinates by all 3D sensor systems 7 for the subsequent movement, a calibration K to the coordinate reference system B0 takes place. During this calibration K, the positions and locations of the 3D sensor systems 7 and thus their respective coordinate systems B1 and B2 are determined relative to the coordinate reference system B0.
- a transformation function in particular in the form of a transformation matrix, is now determined for each of the coordinate systems B1, B2 and applied to these coordinate systems B1, B2 in relation to the relative positions and positions.
- the two 3D sensor systems 7 each assign the corresponding Cartesian coordinates x 0 , y 0 , z 0 to the spatial point P, which correspond to the position of the spatial point P based on the coordinate reference system BO.
- a Cartesian coordinate system such a calibration can also take place in another coordinate system, such as a spherical coordinate system or cylinder coordinate system.
