Definitions
- the present invention relates to a method and a system for monitoring a means of transport environment, in particular in and around a train, as well as a means of transport, in particular a train, with such a system.
- doors can be closed with the help of technical systems, such as anti-trap protection to detect a person or an object in the closing door , monitored and the closed state of the doors can be reported to the driver of the vehicle. to provide an overview of the area around the vehicle before closing the doors or before the vehicle leaves.
- This object is achieved by a method and a system for monitoring a means of transport environment, in particular in and around a train, as well as a means of transport, in particular a train, with such a system according to the independent claims.
- goods to be transported in the surroundings of a means of transport are detected with the aid of at least one sensor.
- Corresponding sensor data are also generated.
- at least one image of at least a part of the area around the means of transport is displayed with the aid of a display device, in particular the means of transport.
- a position of the detected goods in the transport means environment is determined on the basis of the sensor data and (ii) it is checked whether the determined position fulfills a predetermined test criterion.
- the display of the at least one image can then be modified.
- a means of transport within the meaning of the invention is preferably a means of transporting people and / or objects, for example a train composed of several (rail) vehicles or a single vehicle such as a bus.
- a means of transport environment in the sense of the invention is preferably to be understood as the environment in and around a means of transport, in particular a train.
- the transport means environment can include, for example, a platform and / or at least part of the transport means interior.
- the transport means can in particular encompass an area at the edge of a platform and / or an entry or exit area in the transport means, for example in front of a means of transport access.
- An image of a means of transport environment within the meaning of the invention is preferably a pictorial representation or image of the means of transport environment, for example on a screen.
- an image is also to be understood as meaning, in particular, a moving image or an image stream.
- Modifying a representation of an image within the meaning of the invention is preferably a change in the mode of representation of the image.
- the modification of the display can also be implemented by modifying or changing the displayed image itself.
- One aspect of the invention is based on the approach of modifying the representation of at least one image that shows at least part of a means of transport environment of a means of transport when a determined position of a transported goods detected by a sensor in the means of transport, for example a person and / or an object that fulfills a specified test criterion.
- the position of the goods to be transported is preferably determined on the basis of sensor data that are generated by the sensor when the goods to be transported are detected. In this way, it can be checked, for example, whether a person is or would be caught or trapped when a door of the means of transport is closed.
- the driver of the vehicle If necessary, a warning can then be given, preferably in the form of the modified representation of the image. This allows an increase in operational safety.
- the position can be determined as coordinates in a coordinate system, for example of the sensor, by coordinate transformation, possibly also in a coordinate system of the transport means environment.
- a coordinate system for example of the sensor
- coordinate transformation possibly also in a coordinate system of the transport means environment.
- the goods to be transported spatially i. H. is recorded in three dimensions, for example with the help of a stereo camera. This makes it possible to check the position in which the goods to be transported are in relation to a danger area, for example to a closing area of a door of the means of transport.
- the test criterion can serve or at least be understood as a measure for the endangerment of the detected goods by the means of transport or a component of the means of transport. If the test criterion is met, there is preferably a risk to the recorded goods. If, on the other hand, the test criterion is not met, there is preferably no or at least only a low risk to the detected goods to be transported.
- one of several cameras attached to or in a train for example an outside camera or a stereo camera of a counting sensor for counting goods in transit, such as people and / or objects entering or leaving the means of transport, can detect a person who is between two door leaves of a sliding door of the train is located.
- the presence of the person between the two door leaves enables the test criterion to be met, so that the image generated by the camera can be highlighted when shown on the display device, for example a screen in the driver's position of the train. This will It is possible to draw the train driver's attention to the entry and exit situation at the sliding door of the train and, if necessary, to take measures to resolve the situation.
- a predetermined danger area in the area surrounding the means of transport.
- a closing area can in this case be defined, for example, by the closing movement of a door, ie it can correspond to the area swept over by the door when closing.
- the test criterion can be met and the display of the at least one image can be modified.
- Checking the relative position of the determined position and the specified danger area in the transport means enables, for example, a particularly reliable and precise assessment of the question of whether there is a dangerous situation for a person detected in the vehicle environment. In particular, it can be reliably assessed whether a person detected in the vehicle environment would be trapped when the door is closed.
- the at least one image displayed with the aid of the display device is based on the sensor data.
- the sensor data are preferably suitable for both detecting a transport item and determining its position and also for displaying at least part of the transport environment.
- the sensor data can contain image data, for example, in particular in the form of camera images.
- Such sensor data can be generated, for example, by a sensor designed as a camera. From sensor data in the form of camera images, the positions of the transported goods depicted in the images are derived, preferably with the aid of digital image processing algorithms and / or artificial intelligence.
- the at least one displayed image is based on the sensor data, this can facilitate the modification of the display of the image. In particular, this can result in a simple manner which of several displayed images z. B. marked, should be framed and / or colored, for example, to indicate to a vehicle driver the detection of a dangerous situation in the area of the means of transport.
- the modified display of the at least one image has a graphic marking, an enlargement and / or a changed display sequence of several images.
- the image is preferably enlarged with a marker and / or displayed in a different order in relation to other displayed images.
- the at least one sensor is designed as an optical counting sensor, preferably arranged in the access area of a means of transport access, for counting goods such as people and / or objects entering or leaving the means of transport.
- the sensor can, for example, be arranged above a door threshold, in particular installed in the means of transport access.
- a door threshold in particular installed in the means of transport access.
- the access area of the means of transport access can be reliably and essentially completely covered.
- the sensor is preferably designed as a stereo sensor, in particular a stereo camera, and is thus set up to detect the access area, i. H.
- the access area i. H.
- people and / or objects located in the access area are to be recorded in three dimensions.
- the sensor data generated in this way can also be used in a particularly diverse manner for other tasks such as counting transported goods.
- the senor can also be set up to generate a so-called infrared grid with which the goods to be transported are preferably used in the access area of the transport means access, in particular spatially, i. H. in three dimensions.
- the sensor data contain height profile information relating to the height profile of the detected goods to be transported.
- the po- The position of the recorded goods to be transported is determined on the basis of this height profile information.
- Such height profile information can be provided, for example, by a sensor designed as a stereo sensor, in particular as a stereo camera, and allows particularly reliable detection of the goods being transported in the vicinity of the means of transport.
- the position of the detected goods to be transported and / or the test with regard to the at least one test criterion is determined or carried out when there is a closing command to close the means of transport, in particular train doors, of the means of transport.
- a closing command can, for example, be in the form of a closing signal which is generated or triggered by the vehicle driver when a corresponding switch is actuated.
- computing power can, for example, initially be used in a dedicated manner for counting people entering or leaving the means of transport. Only when the closing command is present, for example when a closing signal is detected, can at least part of the computing power be used to determine the position and / or to carry out the test.
- a means of transport access in particular a train door, of the means of transport is identified on the basis of location information assigned to the sensor data.
- the closing command for the identified means of transport access is preferably canceled or at least suspended.
- the location information assigned to the sensor data is preferably based on an assignment of the at least one sensor to the means of transport access.
- each means of transport access to the means of transport can have a sensor assigned to it, in particular a counting sensor, which is each set up to detect transport goods in the access area at the corresponding means of transport access.
- the position of the at least one sensor in the means of transport and thus also the position, for example, of the part of the area around the means of transport shown by the sensor is known.
- the closing command can be reliably canceled for a specific train door, for example, if the test with regard to the test criterion has shown that a person would be trapped when closing the door.
- the closing command is canceled until a bridging command is available.
- a bridging command can be in the form of a bridging signal, for example. It can, for example, be provided that the train driver acknowledges the modified representation, whereupon the bridging signal is generated. This ensures that the train driver has noticed the situation.
- a warning signal is output in the transport means environment as a function of a result of the test. For example, if that The test criterion is met, ie if, for example, a problematic or even critical entry or exit situation is present in the access area at a means of transport, an optical signal such as a flashing light is triggered at the means of transport access. Alternatively or additionally, an acoustic signal such as an announcement can be output at the means of transport access in this case, e.g. B. that the access area should be kept free. In this way, for example, people in the vicinity of the means of transport can be made aware of a possible hazard, for example that they are in a danger area, in particular in the closed area of a means of transport access.
- the warning signal is preferably output on the basis of the location information assigned to the sensor data.
- z For example, it can be determined at which of several means of transport access the warning signal is to be output, since a situation detected in the means of transport environment can be assigned to a specific transport means telzugang, for example, via the location information. This thus enables a particularly targeted output of the warning signal, e.g. B. issuing an announcement on a door blocked by a person.
- the position and / or the test is determined or carried out with the aid of trained artificial intelligence.
- the artificial intelligence can be set up, for example by means of appropriate training, for example by providing appropriate training data, to recognize or track people and / or objects in images based on the sensor data and thereby
- the artificial intelligence can be set up to assess whether a person has been detected and / or a detected object is located within a danger area in the vicinity of the means of transport.
- the use of an artificial intelligence with which z. B. recurring patterns associated with goods and / or dangerous situations for example, allow particularly efficient monitoring of the area around the means of transport.
- a system for monitoring a means of transport environment, in particular in and around a train, according to a second aspect of the invention has at least one sensor that is set up to detect a transport good in the area of the means of transport and generate corresponding sensor data, and a display device that is used to display an image of at least a part of the transport means environment is set up.

- the access area 7, which comprises part of a means of transport interior and part of an external area of means of transport, in the example shown a part of the platform with a safety marking of a danger area at the edge of the platform, is visible in the picture from a bird's eye view.
- Such an image B can, for example, be based on sensor data, in particular image data contained in the sensor data, which are installed by a counting sensor on the means of transport access 6, in particular above a door threshold or a sliding step 6a of the means of transport access 6, and for counting the transport means entering or leaving transport goods 9 is set up, are generated.
- a person who is a transport item 9 within the meaning of the invention is located in the access area 7 in front of the opened wings 6b of a train door.
- FIG. 3 shows an example of an image B from the access area 6 from FIG. 2, in which a predetermined danger area G is drawn.
- the danger area G is indicated by hatching in FIG. 3 and extends from the safety marking on the platform shown in FIG. H. from the outside of the means of transport to the inside of the means of transport via the sliding step, also shown in FIG.

- the vehicle driver can have an announcement output at a means of transport access where the goods to be transported are located within the specified danger area.
- a bridging command can be given, for example by the vehicle driver, which bridges the cancellation of the closing command.
- a bridging command is preferably in the form of a bridging signal that is generated when the result of the test from method step S5b, in particular the fulfillment of the test criterion, e.g. B. is acknowledged by the driver.
- the means of transport Accesses are thus closed in method step S9, so that method 100 ends with the departure of the means of transport at E.
- test in method step S5b shows that the specified test criterion is not met, d. H. that no transport goods are found within the specified danger area, then in a further method step S10 all transport means accesses can be closed directly and the transport means can leave.
