Abstract

To simplify the setup, more particularly for commissioning and maintenance purposes, of imaging sensors, such as for example passenger count sensors and monitoring cameras, in relation to the effort associated therewith and thus to improve the associated costs, it is proposed that an ACTUAL individual image (I-EB) or ACTUAL video (I-VD) of an imaging sensor (S_BG), which is correctly set up and compared in relation to either sensor identification information or connection-related port information and a sensor-specific reference situation relating to positioning, orientation, configuration of a reference parameter set (R-PS) and data-transfer and electrical connection, by means of which imaging sensor at least one individual reference image (R-EB) or reference video (R-VD), in which a marking is located, was taken, is compared with the marked individual reference image (R-EB_M) or reference video (R-VD_M), and on the basis thereof a check is performed to determine whether the set-up imaging sensor (S_BG) is correctly oriented, configured and cabled. If this is not the case, a first error message (FM1), or a first error message (FM1) and a correct, corrected parameter set (PS_K) resulting from the parameter set comparison is generated after a first comparison check and a second error message (FM) is generated after a second comparison check.

Method for setting up imaging sensors, computer program product for setting up imaging sensors, sensor system and installation

The invention relates to a method for setting up imaging sensors according to the preamble of Patentanspru Ches 1, a computer program product for setting bildge bender sensors according to the preamble of claim 9, a sensor device system according to the preamble of Pa tentanspruches 17 and a system according to the preamble of claim 25.

In the establishment of imaging sensors, such as e.g. Passenger counting sensors or surveillance cameras, of equipment, e.g. a vehicles for passenger transport, especially in rail and road transport, or devices for room monitoring, a device of the sensor by a Ex perten is usually necessary to ensure a functionally correct positioning and orientation of the sensor (eg, the counting sensor is functionally correct on aligning a counting line), ensuring correct configuration with parameter sets (eg recording by a video camera with the required resolution and frame rate) and ensuring proper cabling with network or bus systems. In the context of developing, producing,

Commissioning and maintenance (short: the engineering) complex technical systems, such as. Vehicles in Schienenver bund (train), the use of such experts is expensive.

Furthermore, such an expert deployment is superfluous for the case in which several identical installations (for example several identically constructed trains of the same fleet) are to be built, because the same installation must always be made.

In practice, it can be seen that the same device of the sensors in several identical systems fails again and again. suggests. This is due on the one hand to oversight errors of experts or to inadequate execution of installation instructions by installers.

Finally, it turns out that sensors slip during operation due to maintenance work, vandalism or material tiredness of brackets or are supplied in the context of Up dates with wrong parameter sets. In this case, the respective sensor may no longer be able to fulfill its function correctly.

So far, the problem has mainly been solved by detailed procedural instructions for setup and configuration, by regular visual inspection of the installation or by regular manual analysis of the acquired image material.

Beyond the known cases of false equipment is to be assumed by a "dark figure" at faulty facilities that are not noticeable during operation, such. Passenger counter sen- sors that deliver incorrect counts, but not significantly false counts that are noticeable during operation.

The object underlying the invention is to specify a method for setting up imaging sensors, a computer program product for setting up imaging sensors, a sensor device system and a system, with which the setting up, in particular for commissioning and maintenance purposes, imaging sensors, such as Passenger counting sensors and surveillance cameras, in terms of the associated effort is simplified and the associated costs is improved.

This object is achieved on the basis of the in the preamble of Pa tentanspruchs 1 defined method for setting bildge Bender sensors by the features specified in the characterizing part of claim 1. In addition, the task is based on the handle in the Oberbe of claim 9 defined computer program product for setting imaging sensors by the features specified in the characterizing part of claim 9 solves ge.

Furthermore, the object is achieved on the basis of the defined in the preamble of claim 17 Sensoreinrichtungssystem by the features specified in the characterizing part of claim 17.

In addition, the object is achieved on the basis of the system defined in the preamble of claim 25 by the features indicated in the characterizing part of claim 25.

The idea underlying the invention according to the independent claims 1, 9, 17 and 25 is, by matching an actual frame or actual video of an imaging sensor, with respect to either a sensor identification information or a port technical information and a sensor-specific reference situation in terms of positioning, alignment, configuration of a reference parameter set, such as a data transmission and electrical connection, is properly set up and aligned, and taken with the at least one reference frame or reference video in which a marker is located is to check with the selected reference frame or reference video whether the configured imaging sensor is correctly aligned, configured and wired.

If this is not the case, a first error message or a first error message and a corrected, correct parameter set resulting from the parameter set matching become a second error message in the course of a second comparison check generated. In order to be able to recognize a wrong sensor orientation, wrong parameter sets and a wrong wiring, proceed as follows according to the idea outlined above.

First, for a reference plant [e.g. a first vehicle in the rail network (train) of a train fleet] detects the possible installation situations of imaging sensors, and defines the correct positioning, alignment, configuration with parameter sets and cabling by an expert.

Following this specification, the sensors in the reference system are set up and the correct setup is checked by the expert. Subsequently, the specific installation situation and the selected parameter set are stored for these sensors and a plurality of reference individual images and reference videos are recorded, possibly to different light and external conditions that can occur during operation.

Finally, in these reference frames or reference videos distinctive objects are marked, which distinguish installation situations and must always occur in the reference frames or the reference videos in the same place, e.g. Handrails in trains. If such objects do not exist, artificial markers (e.g., red dots) could also be placed in the equipment where the imaging sensors are located.

For the next system of the same design, the sensors are then set up according to the specifications of the expert. Subsequently, an inventive method for setting bildge bender sensors, an inventive computer program product for setting up imaging sensors and / or he inventive sensor device system is used to check for egg nen arbitrary sensor whose device. It is initially assumed that a sensor has been correctly set up. Due to cabling or parameter set, this sensor can then be used according to the method, the computer Program product and / or the sensor device system are addressed accordingly.

In a first step, it is then checked whether a correct actual sensor ID and / or a correct actual sensor type are reported by the sensor. This is done first by comparison with a stored setpoint Id of the sensor and / or a stored target type. If the sensor does not know its actual ID or its actual type, the adjustment is made via a correct connection-related actual port number with a target port number.

In a second step, a check is then made as to whether a configured actual parameter set reported by the sensor coincides with a setpoint parameter set required on the basis of the installation situation and, if appropriate, the sensor type. If not, a first error message is sent to a downstream in-put setting / maintenance system and / or to the sensor. Parallel to this, optionally a corrected, correct parameter set can be transmitted to the sensor either directly or indirectly via the commissioning / maintenance system by appropriate insertion into the sensor.

In a third step, then the sensor-supplied IST individual images or actual videos with the reference frames and reference videos are compared with respect to the lo calized markers (striking objects or artificial markers). If these are not located at the intended locations, then either the sensor has slipped, incorrectly wired or incorrectly installed. In this case, a second error message is sent to the commissioning / maintenance system and / or the sensor. Since faulty devices are not the standard case, these errors can then be corrected manually. Occasional false error messages can also be corrected manually.

In an extension of the invention, the method, the computer program product and / or the sensor device system can be used. be used for monitoring the setup of the sensor during operation. This is useful, for example, if due to the environment or maintenance a Modifika tion in the sensor device (eg by slipping of the sensor, by software updates) is to be expected. In this case, you would just record the reference frames or reference videos only for the sensor that has been set up and not use them for other sensors.

In a further extension of the invention, in the evaluation of individual images or videos, the context of a system [e.g. Vehicle in the rail network (train)], in which the sensors are present, are considered, e.g. whether doors of the train are straight open or closed or just light on or off etc.

In an additional extension of the invention, the misalignment of imaging sensors could be compensated for by intelligent software of the sensor, i. the ak quirierte image material are converted. For example, For example, passenger counting sensors can often view a larger area than is necessary for counting. In this case, the misalignment can be compensated by considering the misalignment shifted image section (assuming moderate misalignments).

In a further extension of the invention, the concept could be extended in principle for sensors of all kinds. However, environmental factors would have to be influenced if necessary. For example, you could import audio sequences for checking a microphone, which are then checked for correct acquisition by the microphone. For example, an automated announcement could be made in one go and then checked for correct entry. This could be used to check both announcement systems and microphones (eg in a microphone unit). The above-outlined comparison of installation situations, parameter sets and reference individual images or reference videos with the respective actual situation makes it possible to achieve:

- Errors in the device of imaging sensors for multiple use in identical systems automated he can be known.

- Errors can be automatically detected by changing the device during operation.

Further advantages of the invention will become apparent from the fol lowing description of an embodiment of the invention with reference to the single FIGURE.

This shows a sensor device system for setting up imaging sensors in a plant, e.g. a vehicle for passenger transport, especially in rail and road traffic, or a device for room surveillance.

FIGURE shows a sensor device system SES for setting up imaging sensors in a system AL, such as a vehicle FZ for passenger transport, especially in rail and road transport, or a device for room monitoring VRÜ. This sensor device system SES contains according to "Opti on A" in the FIGURE at least one imaging sensor S _BG , a database DBK, which is ver connected with the imaging sensor S _B G, and a control unit STE, with the bildge Benden sensor S _BG and the database DBK is connected. The said system components thus also belong to the system AL, the vehicle FZ or the device for room monitoring VRÜ according to "Option A".

The imaging sensor S _BG is preferably a passenger counting sensor or a surveillance camera with a target sensor identification information S-SKI, which is formed, for example, from a configured target sensor identifier S-SK and / or a configured target sensor type data S-STD, and a connective SOLL port information S-PI. In this regard, and with regard to a sensor-specific reference situation, which relates to positioning, alignment, configuration of a reference parameter set R-PS as well as a data transmission technology and electrical connection, the imaging sensor S _B G is set up correctly.

The sensor-specific reference situation, as regards the positioning tion, the orientation, the configuration of the reference parameter set R-PS, the data transmission technology and electrical connection and the correct device of the imaging sensor S _B G is in the system AL, preferably before in the vehicle FZ for passenger transport with passenger counting sensors, eg in rail and road transport, or in the device for room monitoring VRÜ with surveillance cameras, given.

At least one reference single image R-EB or reference video R-VD is recorded with the imaging sensor S _BG thus arranged.

Each reference frame R-EB or reference video R-VD recorded in this way is combined with the reference parameter set R-PS, the desired sensor identification information S-SKI, S-SK, S-STD and the connection-related desired port information S-S. PI is supplied from the imaging sensor S _BG to the database DBK and stored therein.

In addition, the imaging sensor S _BG is soft and hard-formed in such a way that in the recorded reference frame R-EB or reference video R-VD at least one marking a distinctive object or one for the sensor-specific reference situation for recording of the reference frame R-EB or reference videos R-VD gefaf fene artificial marker is located and provided with the marker reference frame R-EB _M or reference video R-VD _M in turn supplied to the database DBK and is stored in this. For setting up the imaging sensor S _B G forms this together with the database DBK a common Funktionsein unit with the control unit STE. For this purpose and to design the functional unit, the control unit STE contains a computer program product CPP for setting up imaging sensors with a non-volatile, readable memory SP, in which processor-readable control program instructions of a program module PGM carrying out the installation are stored, and a processor PZ connected to the memory SP, which executes the control program instructions of the program module PGM for setting up the imaging sensors.

The set-up of the imaging sensor S _B G with the functional unit thus formed and configured is now checked as follows.

In a first step, as a kind of preparation, for carrying out this check of the set-up imaging sensor S _BG , the reference frame R-EB _M or reference video R-VD _M provided with the marking, the reference parameter set R- PS, the target sensor identification information S-SKI, S-SK, S-STD and the connector-related desired port information S-PI loaded into the processor PZ.

Thereafter, in a second step, the examination of the one-directional imaging sensor S _{BG is} performed, in which

an actual sensor identification information I-SKI of the imaging sensor S _BG loaded in the processor PZ, which is preferably and in analogy to the desired sensor identification information S-SKI, S-SK, S-STD from a configured actual sensor identifier I-SK and / or a configured actual sensor type data I-STD is formed, with the target sensor identification information S-SKI, S-SK, S-STD from the database DBK or loaded in the processor PZ technical connection port mation I-PI is compared with the connection technical target port information S-PI from the database DBK, an actual parameter set I-PS of the imaging sensor S _B G loaded into the processor PZ is matched with the reference parameter set R-PS from the database DBK,

- At least one loaded into the processor PZ actual frame I-EB or actual video I-VD of the imaging sensor S _B G out clearly the respective mark with the respective, the mark having reference frame R-EB _M or Refe rence -Video R-VD _{M is} adjusted.

Once these reconciliation checks are complete, you will

1) generates a first error message FM1 or the first error message FM1 and a corrected, correct parameter set PS _K resulting from the parameter set matching if the matching check according to the second indent or the first and second indents does not match the actual value Parameter set I-PS and the reference parameter set R-PS delivers, and

2) generates a second error message FM2 when the comparison check according to the third indent shows that the mark in the actual frame I-EB or actual video I-VD and the mark in the reference frame R- EB _M or reference video R-VD _M are essentially not located in the same place in each frame or video.

The generated by the control unit STE error messages FM1, FM2 and possibly additionally generated, corrected correct, corrected parameter set PS _K are transmitted to commissioning and maintenance systems IWS to a commissioning / maintenance system IWS, which is for this purpose connected to the control unit STE. The corrected, correct parameter set PS _K can be recorded either directly by the control unit STE or indirectly via the commissioning / maintenance system IWS in the set up, imaging sensor S _BG for parameter set correction.

This commissioning / maintenance system IWS can now ent neither according to "Option I" in the FIGURE to the sensor system SES and thus to the system AL, preferably to the vehicle FZ or to the room monitoring device VRÜ, or it is according to "Option II" in the FIGURE is not part of the system SES sensor system and thus also not Be part of the system AL, the vehicle FZ or the room monitoring device VRÜ.

While a discrepancy between the actual parameter set I-PS and the reference parameter set R-PS is signaled with the first error message FM1, the second error message FM2 is used to signal and display a faulty device / misalignment of the imaging sensor S _BG .

The incorrect means / misalignment of the imaging sensor S _BG occurs, for example, by slippage of the sensor, a faulty data transmission technology and electrical connection rule of the sensor, eg by incorrect wiring or obstruction, a poor alignment of the sensor or not yet done software update.

The faulty device / misalignment due to poor direction of the sensor can be compensated either by a loadable in the imaging sensor S _BG or pre installed smart software, which can be, for example, as "App" out compensate, by the bildgeben the sensor S _BG supplied image material is converted, or - in the case of passenger counting sensors or surveillance cameras as imaging sensor S _BG , which often cover a larger Be rich than he is necessary for counting or monitoring - compensate by viewing a misalignment / Fehlaus direction shifted image detail ,

In addition, the misdirection / misalignment of the imaging sensor S _BG for these causes can be always ma naught corrected.

In addition, the control unit STE can still be connected to a memory device SPE for the storage of system-context-specific information. With this memory Direction SPE forms the control unit STE another joint function unit GE and is designed such that for the review of the established imaging sensor S _B G in the system AL, FZ, VRÜ a plant context, insbesonde re plant type, eg rail vehicle of the series ICE , the components or subsystems installed in the system, the system state, eg the operating mode, the state of a component, eg opening a door, is taken into account.

For the storage device SPE, the same applies with regard to the plant affiliation as with the commissioning / maintenance system IWS. The memory device SPE can demzu consequence again either according to "Option I" in the FIGURE Sensoreinungssystemungssystem SES and thus to the system AL, preferably before the vehicle FZ or Raumüberwachungsvorrich device VRÜ belong, or it is not according to "Option II" in the FIGURE System component of the sensor system SES and therefore not part of the system AL, the vehicle FZ or the room monitoring device VRÜ.

In addition to the sensor device system SES described above according to "Option A" in the system AL, the vehicle FZ or the device for room monitoring VRÜ according to "Option A", it is also possible due to the FIGURE

in the sensor device system SES according to "Option B", the at least one imaging sensor S _B G and the control unit STE are included, which thus also belong to the system AL, the vehicle FZ or the device for room monitoring VRÜ according to "Option B",

- In the sensor device system SES according to "Option C" only the computer program product CPP the control unit STE ent hold is and to the system AL, the vehicle FZ or the device for room monitoring VRÜ according to "Option C" finally out of at least one imaging Sensor S _B G hears.

In the case of "Option A" and "Option B", the software implemented real-time check of the installed, imaging Sensor S _B G in the system AL, the vehicle FZ or the device for room monitoring VRÜ instead of place, whereas in the "Option C" the software realized verification of a directed, imaging sensor S _B G outside the system AL, the vehicle FZ or the device for room monitoring VRÜ takes place, for example, in a cloud in which the computer program product CPP is installed or the corresponding software runs.
