Description

Technical Field

[0001] The invention relates to a method for operating an information system, a computer program product and a vehicle. Background Art

[0002] It is known from the prior art to warn the driver of a vehicle, for example when parking the vehicle, of a possible collision with an object representing an obstacle to the vehicle. For this purpose, parking distance control systems are often used in conjunction with optical parking systems. In this case, the display is provided by a separate top view and the drawing of a distance bar. However, such a display requires additional space in the display screen.

[0003] For example, DE 10 2009 055 649 A1 discloses displaying the outline of an obstacle in a so-called measuring lobe to visualize a collision warning for the driver. In this case, a display with a measuring lobe requires its own graphic representation, which does not provide the driver with information about the rest of the vehicle environment. As a result, distances that are not correctly recognized by the vehicle can be easily overlooked by the driver.

[0004] Furthermore, with known solutions, the driver can only verify obstacles detected by the parking distance control system by looking at them from the vehicle, which can lead to a significant loss of comfort, especially in the case of a large number of obstacles. It is therefore desirable to provide the driver with a better overview of the driving situation, so that the driver can visually verify the vehicle surroundings and / or the distance. Summary of the invention

[0005] The object of the present invention is to at least partially eliminate the above-mentioned disadvantages known from the prior art. In particular, the object of the present invention is to improve the overview of the vehicle surroundings when providing information about at least one obstacle in a vehicle.

[0006] The above object is achieved by a method having the features of claim 1, a computer program product having the features of claim 14 and a vehicle having the features of claim 15. Further features and details of the invention are derived from the corresponding dependent claims, the description and the drawings. Features and details described in conjunction with the method according to the invention naturally also apply to the computer program product according to the invention and / or the vehicle according to the invention, and vice versa, so that reference is always made to one another or can be made to one another with respect to the disclosure of the individual inventive aspects.

[0007] According to a first aspect of the invention, a method for operating an information system for providing information about at least one obstacle to a vehicle is provided. The method comprises, in particular in the form of method steps:

[0008] - acquiring environmental data, in particular by means of an environmental sensor device of the information system, to acquire at least one geometrical feature of the obstacle,

[0009] - providing representation data for representing an image of the vehicle environment with geometric features of obstacles, in particular by means of a control unit of the vehicle and / or a vehicle camera of the vehicle,

[0010] - in particular by determining distance data from the vehicle to the geometric feature using the surrounding data by means of the control unit,

[0011] - in particular by modifying the presentation data in dependence on the positioning of the distance data in the presentation data by the control unit for visualizing the distance data in the presentation data,

[0012] - Outputting the modified presentation data, in particular via a control unit and / or a display device.

[0013] Preferably, the vehicle can be a motor vehicle, in particular a motor vehicle in the form of an electric vehicle, and / or an aircraft. The information system can be at least partially or completely integrated into the vehicle. For example, the information system can include an output interface for outputting modified presentation data. The output interface can be integrated into the control unit in order to process presentation data of a display device, for example in the form of an instrument cluster in the passenger compartment of the vehicle and / or in particular an external mobile terminal.

[0014] The environmental data can be acquired based on sensor data of an environmental sensor device of the information system. To acquire the sensor data, the environmental sensor device can include, for example, a radar, a lidar, an ultrasonic sensor device and / or a vehicle camera. Based on the sensor data, geometric features of obstacles can be identified. For example, obstacles can be other vehicles, especially parked vehicles, trees, traffic signs and / or the like. It is also conceivable that the obstacle is part of a narrow area, for example when driving into a parking lot and / or when driving over a bridge that limits the lane horizontally and / or vertically.

[0015] The display data can be generated at least partially or completely from the environment data or can be generated independently of the environment data. The image of the vehicle environment can in particular be a real image (e.g. in the form of image data) or a stylized image (e.g. in the form of a virtualization and / or graphics processing of the vehicle environment). Advantageously, the image can be designed in two dimensions or in three dimensions. Preferably, the vehicle environment can include a plurality of obstacles and / or further environment features, such as lane markings, houses, signs and / or the like.

[0016] When determining the distance data, the distance of the vehicle, in particular a predefined point and / or region of the vehicle, to the obstacle can be determined. It is conceivable to normalize the distance data to a predetermined height from the background and / or a predetermined vehicle component. In order to determine the distance data, the surrounding data can also be analyzed and / or processed in the form of a point cloud.

[0017] For example, the visualization of the distance data may include graphically marking (e.g. in a color-highlighted manner) areas that embody geometric features, areas associated with geometric features and / or specific image elements of the display data. For example, the geometric features may include the side and / or edges of the obstacle facing the vehicle. In particular, it can be arranged that the modification of the display data and / or the visualization of the distance data is only implemented for critical areas in the display data. For example, at least one threshold value of the maximum distance can be defined, for which the display data is modified and / or visualized. When locating the distance data in the display data, it can preferably be arranged that the distance data is directly associated with the geometric features and / or the obstacle, so that visualization can be achieved directly at the obstacle in the image of the vehicle environment.

[0018] The output of the modified presentation data may in particular include displaying and / or providing presentation data with an image of the vehicle environment, in particular in the form of image data and / or in the form of graphic data. For example, the presentation data may be displayed directly on a display device during the output. However, it is also conceivable that the presentation data is sent to a display device and / or provided to a device for displaying on a display device during the output.

[0019] Thus, by modifying the display data, an in particular enhanced illustration of the vehicle environment can be generated. As a result, the user of the vehicle obtains an improved overview of the vehicle environment, wherein the relevant distance information can be displayed at the same time. This can significantly improve user comfort if the driver no longer or only looks around the vehicle for safety reasons to get a sense of the vehicle's surroundings. By having an overview of the vehicle environment, the user can also, for example, visually verify the distance data and / or perform a plausibility check, thereby improving the user's trust in the vehicle and / or the information system (in particular when using driver assistance functions). For example, the method can be carried out when parking the vehicle and / or when driving through a narrow area.

[0020] Preferably, in the method according to the invention, it can be provided that the display data are acquired based on image data of at least one vehicle camera of the vehicle, in particular wherein the positioning of the distance data is performed based on image elements of the image data. The image elements may include pixels, voxels and / or graphic elements (such as, for example, polygons), geometric elements, display areas and / or groups of the above-mentioned graphic elements. It is also conceivable that, when providing the display data, additional information and / or graphics (such as, for example, a diagram of the vehicle) are added to the vehicle environment by calling from a storage unit. Preferably, in the method, distance data of a plurality of image elements and / or a plurality of obstacles can be determined and used to modify the display data. Preferably, when modifying the display data, in particular in the form of augmented reality, the display data is extended in a data and / or computer-aided manner based on the distance data. Thus, the display data may in particular include or consist of image data. In particular, when outputting the modified display data, the modified display data also includes image data with visualization of the distance data in the image data. Advantageously, the image data may be two-dimensional image data or three-dimensional image data. Thus, by using the image data, a realistic image of the vehicle environment can be displayed to the user, whereby in particular details of the vehicle environment that are not contained in the environment data can be realistically reflected and a realistic image of the environment can be displayed to the user. In this case, the user can recognize the distance information in the image data particularly easily. In this case, by associating the image data with pixels, the distance information of the distance data can be directly integrated into the image data for visualization.

[0021] It is also conceivable within the scope of the present invention that the display of the image of the vehicle environment is three-dimensional and / or includes a bird's-eye view of the vehicle environment. For example, the vehicle camera can be designed as a stereo camera, or multiple vehicle cameras can be provided to acquire image data in three dimensions. As a result, the perception of the reality of the modified display data by the user can be further improved. For example, the three-dimensional image can improve the height perception and / or depth perception. As a result, the user can perform a plausibility check on the distance data more simply and / or more reliably. The bird's-eye view of the vehicle environment can be, for example, isometric or planar. In addition, the bird's-eye view can be composed of image data from multiple vehicle cameras. Here, the image data can be at least partially added to the vehicle image. Precisely during the parking process of the vehicle, the vehicle may be surrounded by multiple obstacles. Through the bird's-eye view, the user obtains an improved overview of all obstacles.

[0022] Preferably, the method according to the present invention can be arranged such that the method comprises the following steps:

[0023] - in particular creating an environment map of the vehicle environment by means of the control unit from the environment data,

[0024] Therein, the distance data are determined based on an environment map and / or the display data are modified based on the environment map. In addition, it is also conceivable that the environment map is created based on the distance data. The environment map can also be referred to as a virtual world. Preferably, the environment map can be created three-dimensionally (for example in the form of a point cloud). In particular, the environment map can be created based on sensor data from multiple sensors of an environment sensor device. Based on the environment map, it is possible to acquire multiple obstacles and / or geometric features. Preferably, when determining the distance data, the distance to the vehicle can be determined for each point of the vehicle environment that is identified in the environment map and / or considered as an obstacle. Thereby, critical areas, especially in terms of possible collisions, can be identified in a simple manner. In addition, the positioning of the distance data in the display data can be achieved through the environment map.

[0025] It is further conceivable within the scope of the invention that, in order to modify the presentation data, a coordinate transformation is implemented, in which the environment map and / or the presentation data are converted into a common coordinate system for the environment map and the presentation data. This coordinate system can be the initial coordinate system of the environment data or the presentation data. For example, the coordinate system of the presentation data can include image coordinates, and the coordinate system of the environment map can include world coordinates. In particular, the coordinate transformation can include an image-to-world transformation and / or a world-to-image transformation. Thus, the environment map can be associated with image elements. For example, points of a point cloud of the environment map can be associated with pixels of the image data by means of a coordinate transformation.

[0026] Preferably, in the method according to the invention it can be provided that, when modifying the presentation data, the visualization of the distance data is performed according to the division of the distance data into a plurality of segments extending from the vehicle. For example, the segments can form sectors of a measurement lobe or parts of sectors. In this case, the segments can be projected, in particular, from the vehicle into an image of the presentation data. It is conceivable that the visualization of the distance data is performed according to the segments and / or is respectively constant on the segments. For example, for visualization, the coloring of the image elements can be implemented segment by segment. By means of the segments, the association of the distance data and / or the evaluation of the visualization by the user can be simplified. As a result, in particular in the case of a plurality of obstacles, a clear association of the distance data can be achieved.

[0027] It is also conceivable within the scope of the present invention that, in order to visualize the distance data, when modifying the display data and / or determining the distance data, a polygon with at least one color information is generated based on the geometric features and the environmental data, wherein the color information is specified based on the distance data. For example, the polygon can be formed by points of a point cloud. It can be arranged that, based on the distance data, uniform color information or a color gradient is specified for each of the polygons. Preferably, for the geometric features, the distance value can be determined based on the distance data. The color information can be specified based on the classification of the distance value. For example, for a first distance value, a red color can be specified for the polygon to visualize the distance data, and for a second distance value greater than the first distance value, an orange, yellow or green color can be specified for the polygon to visualize the distance data. As a result, the user can perceive the visualization of the distance data in an intuitive way.

[0028] Furthermore, it can be advantageously provided in the method according to the invention that the polygons are generated according to an envelope model of the environmental data. By means of the envelope model, virtual boundaries of a plurality of elements of the obstacle and / or vehicle environment can be created. In this case, the polygons can be created, for example, according to virtual boundaries of geometric features. In this case, for example, the boundaries can be simplified according to geometric features and / or the minimum distance of the obstacle to the vehicle. As a result, it is not necessary to acquire every detail of the obstacle and / or vehicle environment in the environmental data. As a result, the calculation time can be reduced, so that the output of the modified presentation data can have a short response time.

[0029] Furthermore, it is conceivable in the method according to the invention that the distance data is determined based on first height information of the geometric feature, wherein the first height information of the geometric feature and / or the second height information of the display data are taken into account when modifying the display data. In particular, the second height information can be determined based on the display data. For example, for this purpose, a plurality of temporally consecutive image data can be analyzed, in particular when the vehicle is in motion, in order to determine the second height information. The first height information and the second height information make it possible to visualize the distance information in the display data in a differentiated manner. This allows the user to recognize, for example, whether a highly prominent geometric shape of an obstacle has been correctly identified.

[0030] Furthermore, it can be advantageously provided in the method according to the invention that when modifying the display data, a comparison of the first height information and the second height information is performed, wherein the distance data is positioned in the display data as a function of the comparison of the first height information and the second height information. During the comparison, it can be checked whether the first height information and the second height information are in particular exactly the same or in a tolerance range. It can be provided that if the first height information and the second height information are in agreement, the distance data are visually associated with the geometry data. As a result, the user can recognize, in particular directly at the geometric feature in the image of the vehicle environment, whether a specific geometric feature has a critical distance to the vehicle.

[0031] Furthermore, it is conceivable in the method according to the invention that when modifying the display data, a projection of the distance data, that is to say a visualization of the distance data, onto a background of the vehicle environment is performed based on the first height information and the second height information, so that the visualization of the distance data in the display data can be displayed at obstacles on the background. The background can, for example, include a ground plane. In this case, the background can be identified in particular based on the second height information. For example, starting from the image elements in which the first height information and the second height information coincide, an image element vertical thereto can be determined in which the second height information has a zero height and / or the height of the background. By displaying on the background, it is possible to avoid modifying obstacles, whereby the modified display data can achieve a free and / or unaffected viewing angle of obstacles.

[0032] Preferably, in the method according to the invention, it can be provided that the output of the modified display data comprises displaying the modified display data on a display device of the vehicle. The display device can comprise a display, preferably in the form of a touch screen. Thus, the modified display data with the visualization of the distance data can be provided directly to the driver of the vehicle. It is also conceivable that the modified display data, in particular the visualization of the distance data, can be adjusted and / or personalized via the display device. For example, it can be provided that the projection of the distance data onto the background can be activated and / or deactivated via the distance device.

[0033] Preferably, in the method according to the invention, it can be arranged that the output of the modified display data is carried out according to the at least partially or fully automated parking process for moving the vehicle onto the parking surface. Here, for example, it is conceivable that, in particular, if the user of the vehicle is outside the vehicle during the parking process, the modified display data is sent to an external display device (e.g., a mobile device, such as, for example, a smart phone or a tablet computer). Thus, the user can check at any time during the parking process whether the vehicle has correctly identified the vehicle environment and stopped the at least partially automated parking process and / or manually intervened in the parking process. Preferably, the parking surface on which the vehicle should stay can be automatically identified and visualized when modifying the display data. Additionally or alternatively, it can be arranged that a manual parking process (e.g., according to the low speed of the vehicle) is automatically identified, and the output of the modified display data is carried out according to the identification and / or activation of such a parking process.

[0034] According to another aspect of the invention, a computer program product is provided. The computer program product comprises commands which, when executed by a control unit, cause the control unit to carry out the method according to the invention.

[0035] Thus, the computer program product according to the present invention brings the same advantages as those described in detail with reference to the method according to the present invention. The method can be a computer-implemented method in particular. The computer program product can be implemented as a computer-readable instruction code. In addition, the computer program product can be stored in a computer-readable storage medium (such as a data disk), a removable drive, a volatile or non-volatile memory, or a built-in memory / processor. In addition, the computer program product can be provided or provided in a network (such as the Internet, for example), and the computer program product can be downloaded from the network or implemented online by a user as needed. The computer program product can be implemented by means of software and one or more special electronic circuits (that is, in hardware) or in any mixed form (that is, by means of software components and hardware components).

[0036] According to another aspect of the invention, a vehicle is provided. The vehicle has an information system for providing information about at least one obstacle for the vehicle. The information system includes a control unit for carrying out the method according to the invention.

[0037] The vehicle according to the invention thus brings the same advantages as have been described in detail with reference to the method according to the invention and / or the computer program product according to the invention. The control unit may comprise a processor and / or a microprocessor. Furthermore, the control unit may be part of a central controller of the vehicle. However, it is also conceivable that the control unit is integrated in a distributed manner into one or more non-central controllers, in particular of the vehicle. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] In the following description of several embodiments of the present invention, the same reference numerals are used for the same technical features in different embodiments. DETAILED DESCRIPTION

[0046] Figure 1 The display of modified presentation data 300 in a method 100 according to the invention for operating an information system 10 for providing information about at least one obstacle 2 for a vehicle 1 is shown in a first exemplary embodiment. In this case, a visualization 302 of distance data 210 from the vehicle 1 to the obstacle 2 is performed directly at the location of the obstacle 2 in an image of the vehicle surroundings 3 of the vehicle 1 in which the obstacle 2 is located.

[0047] Transportation 1 Figure 4 As shown in FIG. 1 , method 100 is Figure 5For the method 100 , the vehicle 1 has an information system 10 with a control unit 11 which is designed to carry out the method 100 . For example, a computer program product may be provided which includes commands which, when carried out by the control unit 11 , cause the control unit 11 to carry out the method 100 .

[0048] In order to generate modified presentation data 300, in method 100, firstly environmental data 200 are acquired 101 to acquire at least one geometrical feature 2.1 of an obstacle 2. For this purpose, the vehicle 1 and / or the information system 10 may include an environmental sensor device 20, in order to obtain environmental data 200 based on sensor data of the environmental sensor device 20. For example, the environmental data 200 may include sensor data of a plurality of sensors of the environmental sensor device 20. In particular, an environmental map 202 of the vehicle environment 3 is created 102 based on the environmental data 200. For this purpose, for example, a point cloud may be created from the environmental data 200.

[0049] Furthermore, in the method 100, presentation data 300, in particular with a plurality of image elements, are provided 103 for presenting an image of the vehicle surroundings 3. The presentation data 300 can be acquired on the basis of image data of at least one vehicle camera 21 of the vehicle 1. The vehicle camera 21 can in particular be part of the surroundings sensor device 20. However, in particular in contrast to the surroundings map 202, the image data of the presentation data 300 can continue to be retained and / or only modified. The image elements of the presentation data 300 can be formed, for example, by pixels of the image data.

[0050] Here, Figure 1 The display data 300 are shown in the form of a top view of a vehicle environment 3 with a vehicle 1. The display data 300 can be composed of image data from a plurality of vehicle cameras 21. In particular, the output 106 of the modified display data 300 can be carried out in accordance with an at least partially automated parking process for moving the vehicle 1 onto a parking surface. The top view has the advantage that the user can simultaneously identify and monitor a plurality of obstacles 2 during the parking process. However, it is also conceivable that the display data 300 includes image data from a single vehicle camera 21 (in Figure 2 In particular, if a plurality of vehicle cameras 21 are used and / or the vehicle camera 21 is designed as a stereo camera, it can be provided that the image of the vehicle surroundings 3 is presented in three dimensions.

[0051] Furthermore, the method 100 comprises determining 104 distance data 210 of the vehicle 1 to the geometric feature 2.1, that is to say in particular to the obstacle 2, based on the environment data 200. Preferably, the distance data 210 comprises distance values ​​and / or distance information of a distance or distances between the vehicle 1 and the obstacle 2. The distance data 210 can be determined based on the environment map 202. However, it is also conceivable that the distance data 210 are determined before the environment map 202 is generated and the environment map 202 is determined based on the distance data 210.

[0052] Furthermore, the display data 300 are modified 105 in accordance with the positioning of the distance data 210 in the display data in order to visualize 302 the distance data 210 in the display data 300. Advantageously, for the visualization 302 of the distance data 210, in particular when modifying 105 the display data 300 and / or when determining 104 the distance data 210, a polygon 201 having at least one color information is generated in accordance with the geometrical feature 2.1 and the environment data 200, in particular the environment map 202. In this case, the polygon 201 is generated in accordance with an envelope model 203 of the environment data 200, as in Figure 3 . In this case, a virtual boundary is generated around the obstacle 2, to which the distance data 210 are related. In this case, the color information for the polygon 201 is specified as a function of the distance data 210. Advantageously, the modification 105 of the presentation data 300 can be carried out as a function of the environment map 202. For this purpose, a coordinate transformation can be carried out, in which the environment map 202 and / or the presentation data 300 are converted into a common coordinate system for the environment map 202 and the presentation data 300.

[0053] As in Figure 1 and Figure 2As shown in , it can furthermore advantageously be provided that the visualization 302 of the distance data 210 in the presentation data 300 is performed at the obstacle 2 on the background of the vehicle environment 3 by positioning the distance data 210 in the presentation data 300. For this purpose, the distance data 210 are determined on the basis of the first height information 211 of the geometrical feature 2.1. Subsequently, when modifying 105 the presentation data 300, a comparison of the first height information 211 with the second height information 212 is performed. The second height information 212 is associated with an image element and is determined on the basis of the presentation data 300. Furthermore, when modifying 105 the presentation data 300, a projection of the distance data 210 onto the background of the vehicle environment 3 is performed on the basis of the first height information 211 and the second height information 212 in such a way that firstly, in particular, the consistency of the first height information 211 and the second height information 212 is identified in a common coordinate system, and the projection onto the background is performed starting from the image element with the consistency. However, it is also conceivable, in addition or alternatively, that the visualization 302 is performed directly in the image element, in particular without projection, so that, for example, on the basis of Figure 2 The display enables the user to vertically associate the visualization 302 of the distance data 210 directly with the geometrical feature 2 . 1 .

[0054] As in Figure 1 , it may also be advantageous if, when modifying 105 presentation data 300 , visualization 302 of distance data 210 is performed based on a division of distance data 210 into a plurality of sections extending from vehicle 1 . This may simplify the perception of distance data 210 and / or visualization 302 of obstacle 2 .

[0055] Next, output 106 of the modified presentation data 300 is performed. For example, output 106 of the modified presentation data 300 may include displaying the modified presentation data 300 on a display device 12 of the vehicle 1 in order to provide the modified presentation data 300 to the driver of the vehicle 1 .
